Summary

Surfaces batch accounting data (model, token usage, and cost) in the logs table UI, and ensures batch_debug is included in list queries so that data is available for display. Batch log entries that lack a top-level model, token usage, or cost now fall back to values derived from the batch debug accounting breakdowns. Additionally, the server version is propagated into the context at bootstrap so that batch accounting settlement logs carry a UserAgent field.

Changes

  • Added BifrostContextKeyRuntimeVersion context key and set it at server bootstrap so the runtime version is available throughout the request lifecycle.
  • Added userAgentFromContext helper that reads the runtime version from context and builds a "bifrost/<version>" user agent string, falling back to "bifrost".
  • Passed the resolved user agent into buildAggregateLog and set it as UserAgent on the resulting log entry during batch accounting settlement.
  • Added batch_debug to the listSelectColumns query so batch debug data is returned when listing log entries.
  • Added a batchAccountingDisplay helper that aggregates model and token usage across batch_debug.accounting.model_breakdowns, returning "mixed" when multiple models are present.
  • Model and token usage columns now fall back to batchAccountingDisplay when the top-level fields are absent.
  • The cost column now renders the settled batch cost (from batch_debug.accounting.cost) with a tooltip explaining it is billed once, rather than showing N/A.
  • Replaced batchDebug-gated UI logic with an isBatch flag derived from the log object type, so batch cancel and list operations are handled correctly even when batch_debug is absent.
  • Batch ID and status in the detail view now fall back to the raw provider response payload when batch_debug is not present.
  • Moved the status badge from the summary header section into the Details tab alongside the batch ID, so it is consistently sourced from either batch_debug or the raw response.

Type of change

  • Bug fix
  • Feature
  • Refactor
  • Documentation
  • Chore/CI

Affected areas

  • Core (Go)
  • Transports (HTTP)
  • Providers/Integrations
  • Plugins
  • UI (React)
  • Docs

How to test

  1. Submit a batch request and wait for it to settle.
  2. Open the logs table and locate the batch log entry.
  3. Verify the model column shows the correct model name (or "mixed" for multi-model batches).
  4. Verify the token usage column shows aggregated prompt, completion, and total tokens.
  5. Verify the cost column shows the settled batch cost with a tooltip reading "Settled cost of this batch, billed once." instead of N/A.
  6. Open a batch cancel or batch list log entry and verify the Details tab and batch ID/status fields render correctly without batch_debug.
# Core/Transports
go test ./...

# UI
cd ui
pnpm i || npm i
pnpm build || npm run build

Screenshots/Recordings

Before: Model, token usage, and cost columns showed N/A for settled batch log entries. Batch cancel and list log entries did not render a Details tab or batch status.

After: All three columns display values derived from batch_debug accounting data, with a tooltip on the cost cell. Batch cancel and list entries correctly show or hide the Details tab based on object type.

Breaking changes

  • Yes
  • No

Security considerations

No new auth, secrets, PII, or sandboxing concerns introduced.

Checklist

  • I read docs/contributing/README.md and followed the guidelines
  • I added/updated tests where appropriate
  • I updated documentation where needed
  • I verified builds succeed (Go and UI)
  • I verified the CI pipeline passes locally if applicable

Review Change Stack

📝 Walkthrough

Summary by CodeRabbit

  • New Features

    • Added batch accounting details to the logs table, including aggregated token usage, fallback model information, and settled costs.
    • Batch log details now display batch IDs, statuses, and request/response payloads even when debug data is unavailable.
    • Batch operations are automatically recognized and no longer show irrelevant Messages or Tools tabs.
  • Bug Fixes

    • Improved runtime version tracking for aggregated batch logs.
    • Fixed log queries to include batch debugging information.

Walkthrough

Batch aggregate logs now persist runtime-version user agents. Log queries include batch debug data. The logs table displays batch accounting fallbacks. Batch detail views detect batch operations from object names and resolve identifiers and status from debug or raw response data.

Changes

Batch accounting logs

Layer / File(s) Summary
Expose batch accounting data
core/schemas/bifrost.go, transports/bifrost-http/server/server.go, framework/batchaccounting/accounting.go, framework/logstore/rdb.go
The server adds runtime version to context. Aggregate logs persist a versioned user agent. Log list queries select batch_debug.
Render batch accounting fallbacks
ui/app/workspace/logs/views/columns.tsx
The logs table derives fallback model and token values from batch accounting data. It displays settled batch cost in a tooltip when direct cost is unavailable.
Render batch operation details
ui/app/workspace/logs/sheets/logDetailView.tsx
The detail view detects batch operations from object names, parses raw payloads, resolves batch ID and status, and hides Messages and Tools tabs.
Estimated code review effort: 3 (Moderate) ~20 minutes

Merge Risk: 🔴 Critical · up to 800c6

The PR has a release-blocking compile risk because server bootstrap references a runtime-version context key reported as undefined, which can prevent the Go build from succeeding. It also retains bounded UI accessibility and state-association issues. Merge should be blocked until the compile issue is resolved.

2303-2304: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use customId as the stable accordion key.

An item reorder can attach open accordion state to a different batch item because both keys include the array index. customId already has a fallback for missing provider IDs, so do not append index.

<Note>
v2.0.0 is the first stable release on the 2.0 line. This changelog rolls
up `2.0.0-prerelease1` (based on
[v1.6.3](https://docs.getbifrost.ai/changelogs/v1.6.3)),
`2.0.0-prerelease2`, `2.0.0-prerelease3` and the final release window,
so it is the complete delta for a deployment upgrading from any v1.6.x
release. Fixes that also shipped on the v1.6.x line after v1.6.3 are
listed once here.
</Note>

<Warning>
**Breaking changes.** Read the [v2.0.0 migration
guide](https://docs.getbifrost.ai/migration-guides/v2.0.0) before
upgrading.

- **Custom plugin downloads are SSRF-protected** - a plugin `path`
pointing at an http(s) URL is rejected if it resolves to a loopback,
private, CGNAT, link-local or otherwise non-public address, and every
custom plugin path is re-verified on each restart, including ones
defined in `config.json`.
- **Custom plugin create and update require admin authentication** -
`POST /api/plugins` and `PUT /api/plugins/{name}` reject a custom `path`
when the caller only got through because dashboard auth is disabled or
unconfigured.
- **Governance APIs moved under `/api/governance/*`** - `/api/teams`,
`/api/users`, `/api/roles`, `/api/audit-logs` and other top-level
governance paths moved under one namespace; Team and User lists use
`limit`/`offset` pagination. Routing rules and the complexity analyzer
moved from `/api/governance/*` to `/api/routing/rules` and
`/api/routing/complexity-analyzer-config`; the old paths remain as
deprecated aliases.
- **`HTTPTransportPreHook` now runs after authentication** - the
pipeline is `HTTPTransportPreAuthHook -> auth -> HTTPTransportPreHook ->
handler`. Plugins that inject a credential (`x-bf-vk`, `Authorization`,
`x-api-key`) must move that work to the new `HTTPTransportPreAuthHook`,
and Go plugins implementing `HTTPTransportPlugin` must add the method
(`.so` plugins that predate it are skipped for that phase).
- **Legacy telemetry attributes removed** - the `gen_ai.*`-namespaced
Bifrost-internal span attributes,
`gen_ai.usage.prompt_tokens`/`completion_tokens`, the nanosecond
`time_to_first_token` attribute and `x-bf-prom-*` request-header
Prometheus dimensions are gone from the OTel and Prometheus connectors.
Dashboards should read the `bifrost.*` keys and `time_to_first_chunk`.
- **Gemini tool preference** - a Gemini API request carrying both
function declarations and Google Search without
`include_server_side_tool_invocations` now keeps the function
declarations and drops Google Search (previously the opposite). Set
`include_server_side_tool_invocations: true` to send both on Gemini 3
models. Vertex is unaffected.
</Warning>

## ✨ Features

- **Batch Accounting** - Provider batch jobs are tracked in a new
`batch_jobs` table and settled asynchronously: results are priced per
model from catalog batch rates (0.5 default ratio) on the `/results`
path, one aggregate cost log is written idempotently with the creating
request's identity, a background sweeper with ownership fencing
re-drives jobs that timed out, settled usage is charged exactly once to
the creating user's budgets and rate limits (including unscoped virtual
key budgets on model-less batch-create requests), mixed-model batch rows
are repriced during cost recalculation, and the log detail view shows a
Batch Details block with per-state request counts and the settled cost
(#5291, #5292, #5293, #5294, #5295, #5296, #6109, #6121, #6376, #6410,
#6474, #6505)
- **Claude-on-Vertex Batches** - Vertex batch jobs route Anthropic
models to `publishers/anthropic/...`, build Claude-on-Vertex JSONL
instances, round-trip `custom_id`, and preserve `tools`, `toolConfig`,
`cachedContent`, `labels` and `display_name` on Gemini/Vertex batch
requests (#5368)
- **Input / Output Cost Split** - Every log carries `input_cost`,
`output_cost` and `additional_cost` (guardrails, semantic cache, MCP)
next to the total, across the RDB, ClickHouse, matviews, recalculation
and the quota API; speech, transcription and OCR usages carry
`BifrostCost`; the log detail view shows the split with per-category
detail (#6511)
- **Bifrost Overhead Latency** - `upstream_latency` and
`overhead_latency` are recorded on every log, aggregated (avg, p90, p95,
p99) in the dashboard's new Bifrost Overhead chart and shown in the log
detail view; the overhead is decomposed by span self-time into
serialization, conversion, plugins, middleware, key selection, queue
wait, networking, client delivery and scheduling buckets (including
streaming per-chunk parse, conversion and backpressure and the worker
hand-off), persisted to `overhead_breakdown` and rendered as a stacked
bar in the log detail view; a `bifrost_overhead_latency_microseconds`
histogram is exported to Prometheus and OpenTelemetry and
`upstream_latency_ms`/`overhead_latency_ms` tags to Maxim, while
breakdown spans are kept out of observability connectors (#5533, #5534,
#5535, #6345, #6388, #6389, #6433, #6470, #6495)
- **Notification Center** - Role-targeted dashboard notifications stored
in the database, delivered over WebSocket and surfaced in a topbar tray
via `GET/POST /api/notifications` (#6207, #6227, #6324)
- **Topbar and Responsive Dashboard** - Persistent topbar with page
titles, theme toggle, external links, user menu and version; responsive
layouts across all views with truncation and tooltips for long values
and icon-only buttons; version-skew detection with an auto-reloading
upgrading screen (#6196, #6105, #6126, #6204, #6232, #6330, #6370,
#6476, #6485, #6493)
- **Video Edits** - `POST /v1/videos/edits` applies prompt-driven edits,
upscaling and background removal to an existing video supplied as bytes,
a URL or a provider video ID, on OpenAI and Runware (#6270)
- **Runware Chat, Catalog and Media Operations** - Chat completions,
streaming and Responses via Runware's OpenAI-compatible endpoint,
`ListModels` from the curated catalog, image upscale via
`/v1/images/edits` (`type=upscale`), image-to-3D and async 3D generation
via `/v1/videos` (`type=3d`), provider-reported per-task cost, and a raw
`/runware_passthrough` route (#6260, #6372, #6208, #6075)
- **JSON Image Edits** - `POST /v1/images/edits` accepts JSON bodies
with URL or base64 images and typed extra params in addition to
multipart (#6418)
- **OpenAI Ultrafast Service Tier** - `service_tier: "ultrafast"` is
forwarded only to models that support it and billed at dedicated
ultrafast rates, with matching custom pricing override fields (#6396,
#6399)
- **Service Tier on Logs** - Logs record the tier actually served,
including Anthropic's `service_tier` from `message_start` on streams,
with a Service Tier column and detail field so repricing uses the served
tier (#6233, #6236)
- **Pricing Fields** - New per-request flat fee (`cost_per_request`),
megapixel-based image tiers (4/8/16/32/64 MP), per-size and joint
size+quality image rates for `gpt-image-1`-style models, and
`input_cost_per_query` for rerank flow through datasheet sync, the cost
engine, custom overrides, the API and the UI override form; upscale
output resolution is backfilled from `target`/`factor` on Replicate so
tiered rates bill the real output size (#6079, #6082, #6083, #6379,
#6380)
- **Model Catalog Pricing and Overrides** - Pricing data in the model
catalog (thanks [@johnbrett](https://github.com/johnbrett)!), with
resolved pricing overrides exposed on `/api/models/details` and on
catalog rows, shown in the dashboard (#6055, #6056, #6058)
- **Typed Embeddings on Bedrock** - Titan V2 `embeddingTypes` and Cohere
`embedding_types` on Converse, the native invoke route and LangChain
`BedrockEmbeddings` (#6381)
- **Rerank Upgrades** - Structured JSON documents, `return_documents`,
`next_token` pagination, caller document IDs preserved in every result,
Cohere-shaped errors, cross-provider responses converted back to the
caller's wire shape, and `/genai/v1/rank` served cross-provider (#6328,
#6301, #6432)
- **OpenRouter Speech, Transcription and Embeddings** - TTS and STT
through OpenRouter's audio endpoints, and embedding models included in
`ListModels` (#5734, #6264)
- **Grok on Bedrock Mantle** - `xai.` models route through the
`openai/v1` Mantle path (#6022)
- **Gemini 3 Thinking Levels** - A per-model `thinkingLevel` support
table clamps requested levels to the rungs each model implements;
`reasoning_effort: "none"` sets the model's floor level instead of
zeroing `thinkingBudget` (#6280)
- **Datasheet-Backed Compatibility** - Anthropic, Bedrock, Cohere and
Gemini request shaping (adaptive thinking, native effort,
disable-reasoning, mid-conversation system turns, computer-use and
text-editor tool generations, default max output tokens, tool
validation) is resolved from model capabilities instead of hardcoded
model-name checks (#6281, #6492)
- **Reasoning Effort None** - Models that reason by default but do not
support reasoning with tool calls get `reasoning.effort: "none"` when
they advertise `supports_none_reasoning_effort`, instead of losing
`reasoning` entirely (#6293)
- **HTTP Transport Pre-Auth Hook** - New `HTTPTransportPreAuthHook`
plugin phase runs before transport authentication so plugins can inject
credentials such as `x-bf-vk`; a `virtual-key-from-config` native plugin
example ships alongside it (#6375, #6373)
- **Plugin Inject Limits** - Per-plugin `semaphore_size` and
`inject_timeout` on `PluginConfig` bound observability `Inject` calls so
a hung connector releases its slot (#6341)
- **Harness Session Autodetection** - Claude Code, Codex CLI and
OpenCode session headers populate the session ID when `x-bf-session-id`
is absent (#6333)
- **Auth and Model Check Skip Paths** - Context keys let trusted
internal callers bypass auth resolution, and let evaluate-only requests
such as `/inspect` bypass the virtual key provider and model allowlists
while budgets and rate limits still apply (#6124, #6479)
- **Passthrough Encoding Negotiation** - Forwarded `Accept-Encoding` is
filtered to decodable codecs (gzip, deflate, brotli, zstd; gzip and
identity for streams) and chained content encodings are decoded (#6360)
- **Routing Plugin** - Routing rules and the complexity router live in a
dedicated `routing` plugin that runs after governance so rules evaluate
on the fully stamped context; endpoints moved to `/api/routing/rules`
and `/api/routing/complexity-analyzer-config` with deprecated
`/api/governance/*` aliases; complexity routing now reads the text of
mixed text+image turns (#6144, #6145, #6146, #6147, #6253)
- **Dimension Scope Ceiling** - Grouped log analytics (rankings,
histograms, key pairs) are bounded to the customer, team, business unit,
user and virtual key ids the caller may see (#6262)
- **MCP Per-User OAuth and Token Exchange** - MCP clients can hold
per-user OAuth credentials and per-user headers, configurable from
`config.json` as well as the UI, with a documented shared vs
per-identity token lookup contract, `oauth_config.resource` (RFC 8707),
VK/Users filters on the OAuth Grants and MCP Auth Sessions sidebars and
one shared create/install client form; `token_exchange` gains
`use_idp_credentials` to reuse SSO login app credentials for providers
such as Microsoft Entra ID (`client_id` becomes optional) and combines
`offline_access` with `<audience>/.default` for Entra OBO; shared-OAuth
clients show `needs_reauth` when their token row is invalidated,
`Reauthorize` is limited to shared clients, the OAuth flow claim is
atomic against concurrent reauth, stored scopes survive a decode
failure, and credential caches propagate cancellation and version their
entries (#6068, #6069, #6078, #6411, #6428, #6429, #6504)
- **MCP Connection Lifecycle and Tool Discovery** - Discovered tools
persist and resync uniformly across all client types through a
hash-gated core callback, surviving restarts and propagating across a
cluster; connections use make-before-break reconnects with ephemeral
clients rebuilt across the whole connect+init retry, last-known tool
maps preserved, connect attempts bound to entry identity and background
reconnects deduped; `needs_session_stickiness` is pinned across
`config.json` reconciliation; updating static headers on a sticky client
pre-flight verifies the new credential and swaps it onto the live
connection, per-call shared-credential clients refresh tools
synchronously, and a failed enable parks the client at `Disabled` so it
can be retried; the global `tool_sync_interval` hot-reloads and re-times
running checkers; state badges render with spaces and the `disconnected`
filter bucket is now `unstable` (#6409, #6430, #6431, #6483, #6502)
- **Air-Gapped MCP Catalog** - `mcp_library_sync_interval: 0` disables
catalog sync and `file://` URLs load the MCP server library from disk
(#6195)
- **MCP Log Redaction and Plugin Logs** - MCP tool logs carry redaction
mappings and plugin logs (#5744, #5746)
- **Splunk Connector Configuration** - `config.schema.json`, Helm values
and dashboard entries for the Splunk HEC observability connector (#6296,
#6091, #6099)
- **Helm Broker Clustering** - `bifrost.cluster.type: broker` with
broker address, port and TLS settings alongside the existing mesh
transport (#6398)
- **HTTP/2 Ping Interval in the UI** - Provider network configuration
exposes `http2_ping_interval_in_seconds` (#6228)
- **Status Code Badges** - Error and passthrough logs show the upstream
HTTP status code in the log detail header (#5536)
- **Server-Side Tool Calls in Logs** - `web_search_call`,
`code_interpreter_call` and similar Responses items render their full
payload in the log detail view (#6475)
- **Gemini Server-Side Tool Calls** - Gemini `toolCall`/`toolResponse`
parts surface as `web_search_call` items with their own call ID and
queries, unmapped tool types are preserved on the native round-trip, and
each `thoughtSignature` appears exactly once on replay (#6071)
- **Bedrock VPC Endpoints** - AWS Bedrock keys can target VPC endpoints
(#6064)
- **W3C Trace ID Propagation** - Requests carry a W3C trace ID on the
context (#5945)
- **Durable Background Jobs** - New `sidekiq` background-job table,
store methods, and runner with recovery and reaper; cost recalculation
migrated to a durable, resumable and cancellable job with polling
instead of SSE (#5800, #5801)
- **Separate OTEL Metrics Pipeline** - The OTEL collector supports a
metrics tab independent of traces, plus separate headers for traces and
metrics (#5939, #5940)
- **Grouped Logs View** - The logs table groups fallback chains under
expandable roots backed by the new `roots_only` filter with child
aggregates, and the model catalog persists tab, search and provider in
the URL (#5522, #5737, #6059)
- **User Agent and App Attribution** - Logs and MCP tool logs record
user agent, app, source, decision, app key and device ID, with custom
user-agent mapping and dashboard dimension rankings; MCP tool logs
observed by the Bifrost Edge agent can be ingested with device, app key,
decision and source attribution
- **S3 Log Export Metadata** - Additional metadata is written alongside
S3 log exports (#6070)
- **Matview Maintenance Off Switch** - `matview_refresh_interval`
accepts `"off"` to disable logstore matview maintenance entirely (thanks
[@jeremym-tanium](https://github.com/jeremym-tanium)!) (#5693)
- **Video Request Info in Logs UI** - Video requests surface their
details in the logs UI (#5946)
- **Shell Rewriter Hook** - The UI handler exposes a `ShellRewriter`
hook for pre-hydration HTML rewriting (#5807)
- **Custom Branding** - Logo and icon branding support with an OSS
fallback stub, cached in localStorage to prevent a logo flash on load
(#5806, #6096)
- **User Assignment on Virtual Keys** - Users can be assigned from the
virtual key sheet (#5863)
- **Quarterly Budgets** - Quarterly budget windows with a configurable
fiscal year start for customers and virtual key provider configs,
surfaced in budget labels (#5996, #5997, #5999, #6115, #6116)
- **Sarvam AI Provider** - Added Sarvam AI as a first-class provider
with chat, text-to-speech, and speech-to-text support (thanks
[@Purvi09](https://github.com/Purvi09)!)
- **ElevenLabs Sound Effects** - Added text-to-sound generation support
via `/v1/sound-generation` (thanks
[@SecretSun](https://github.com/SecretSun)!)

audit log archival
- **Alerting Configuration** - Alerting schema in `config.schema.json`
with declarative channels and CEL-based rules, Helm chart support, and
enterprise fallback pages
- **Canonical Model Names** - Dashboard model rankings now show
canonical model names instead of inference-profile IDs (thanks
[@satyamkrishna](https://github.com/satyamkrishna)!)

mirrored schema locations in isolated deployments
- **Vertex Single-Region Config** - Enforce single-region configuration

- **ChatGPT Passthrough** - Added a ChatGPT passthrough route on the
OpenAI integration with dedicated request handling
- **Edge Fallback Pages** - Added fallback pages for Bifrost Edge
control views (config, devices, inventory) backed by governance resolver
support
- **Agent Handover View** - Added an agent handover page with seeded
end-to-end data support
- **First-Time Setup Token** - A setup token gates first-time setup so a
fresh deployment is not open to the world, and the onboarding checklist
is back, completing its dashboard auth step on SSO deployments (#5759,
#5784, #6322)

## 🐞 Fixed

- **Structured Output Schema Order** - `response_format` JSON schemas
are forwarded byte-for-byte to OpenAI, Anthropic, Bedrock, Gemini and
Cohere so the model generates fields in the caller's declared order
instead of a re-sorted one (#6235)
- **Thinking Block Typing on Streams** - Reasoning items carrying both
an encrypted payload and a visible summary open as `thinking` blocks
instead of `redacted_thinking` (#6292)
- **Replayed Thinking Blocks via `bedrock/` Prefix** - Content-less
`tool_result` blocks are kept, interleaved block order is preserved,
`incomplete` maps to `error` on Converse, and pending reasoning is
consumed by its owning item, so multi-turn tool use no longer wedges
(#6346)
- **Gemini 400s on Claude Code Traffic** - Trailing assistant prefills
are trimmed and mid-conversation system turns are inlined for
Gemini/Vertex; `extra_fields` is echoed on `/anthropic/v1/messages`
(#6363)
- **Bedrock Tool Use IDs** - IDs longer than 64 characters or outside
Bedrock's charset (such as Gemini thought-signature IDs) are aliased
deterministically on both `tool_use` and `tool_result` (#6300)
- **Azure Responses Stream Errors** - Terminal `error` and
`response.failed` events inside an already-open HTTP 200 SSE stream are
surfaced as errors with their nested type, code and message (thanks
[@dani29](https://github.com/dani29)!) (#6302)
- **GenAI SSE Heartbeats** - GenAI streams delimit heartbeat comments so
Google SDK clients preserve the following event, while older openai-go
clients keep the bare heartbeat (thanks
[@dani29](https://github.com/dani29)!) (#6252)
- **OpenCode max_tokens** - `max_tokens` is preserved for
OpenCode-compatible chat endpoints (thanks
[@Alex-wangyang](https://github.com/Alex-wangyang)!) (#6458)
- **HuggingFace Streaming Usage** - HuggingFace is no longer listed as
omitting the `[DONE]` marker, and `stream_options.include_usage`
defaults on its chat streaming path, so streamed calls stop reporting
zero tokens and zero cost (thanks
[@elliottrabac](https://github.com/elliottrabac)!) (#6478)
- **Provider Key Name on Update** - A key PUT that omits `name` no
longer clears it, and already-exists errors keep their constraint detail
(thanks [@cpsc](https://github.com/cpsc)!) (#6417)
- **Bedrock Mantle Streaming** - Bedrock Mantle is registered in
`ProviderSendsDoneMarker` so streams end after `finish_reason` (#6021)
- **URL-Sourced Files and Images** - `gs://` URIs go to Gemini/Gemma as
`fileData.fileUri` and are read from Cloud Storage for Claude-on-Vertex,
`s3://` references go to Bedrock Converse as `s3Location`, Bedrock
rerank synthesizes the foundation-model ARN from a bare model ID, OpenAI
file blocks keep `file_url`, non-http schemes pass through on the OpenAI
and native-Anthropic paths, and Gemini always emits a candidate with its
finish reason and drops payload-free parts (#6239)
- **Together and Alias Pricing** - The management catalog resolves
runtime provider `together` to the datasheet identity and prices
configured aliases through their target model (thanks
[@dani29](https://github.com/dani29)!) (#6257, #6320)
- **Redis Vector Store TAG Escaping** - All RediSearch special
characters are escaped in TAG query values (thanks
[@AdityaPainuli](https://github.com/AdityaPainuli)!) (#5351)
- **MCP Tool Sync Interval Corruption** - Toggling an MCP client's
enable/disable switch no longer corrupts `tool_sync_interval`; the value
is a whole number of minutes, negative values are rejected instead of
silently disabling sync, and re-enabling a per-call client restarts its
discovery cycle (#6409, #6502)
- **MCP Tool Map Staleness** - `SetClientTools` replaces the in-memory
tool map instead of merging, so tools removed upstream leave memory once
the database has dropped them (#6484)
- **SSE Reconnect Identity** - `OnConnectionLost` on SSE MCP clients is
gated on connection identity so a stale connection cannot tear down its
replacement
- **Connector Header Redaction** - `Authorization`, `x-api-key`,
Cloudflare Access and AWS ALB OIDC headers are redacted before export to
every observability backend (#6371)
- **Vertex Mixed Tools** - Vertex AI accepts function declarations and
Google Search in the same request without
`includeServerSideToolInvocations`, and search localization via
`retrievalConfig.latLng` is preserved (#6066)
- **Gemini Tool Preference** - When tool combination is disabled,
function declarations win over Google Search so the model can still call
the caller's tools (#6065)
- **Bedrock Stop Reasons** - Bedrock `content_filter` and
`guardrail_intervened` stop reasons map to `incomplete` status with a
`content_filter` reason
- **Encrypted Reasoning on Compaction** - The fail-soft that strips
`encrypted_content` before retrying a rejected request also covers
`/v1/responses/compact` and count-tokens requests, and recognizes
Anthropic's `redacted_thinking` rejection (#6041, #5960)
- **DAC-Scoped VK Reads** - `from_memory` virtual key reads are blocked
for DAC-scoped callers
- **Path Normalization Auth Bypass** - Fixed a path normalization flaw
that allowed auth to be bypassed (#5763)
- **Minimal Reasoning Effort on GPT-5 Models** - `reasoning_effort:
"minimal"` is preserved for GPT-5-family OpenAI models instead of being
downgraded to `low` (thanks [@jitokim](https://github.com/jitokim)!)
(#6046)
- **Gemini Truncated Response Finish Reason** - Truncated Gemini
responses report `MAX_TOKENS` instead of `OTHER` (thanks
[@AdityaPainuli](https://github.com/AdityaPainuli)!) (#5979)
- **Null Tool-Call Function Name on Streaming** - Streaming continuation
deltas no longer materialize an absent tool-call function name as `null`
(thanks [@AdityaPainuli](https://github.com/AdityaPainuli)!) (#5966)
- **Bedrock Document Uploads** - Fixed Bedrock file handling in
inference so office and PDF documents sent as OpenAI `type: "file"` are
accepted (#5947)
- **xAI Usage Cost** - Fixed USD cost ticks for xAI usage (#5950)
- **Governance List-Models Call** - Budgets and rate limits no longer
trigger a list-models call (#6051)
- **Realtime Response Create Input** - Guarded `response.create` input
(#6050)
- **Governance Rate-Limit Reset CPU** - Guards against invalid reset
timeouts, parallelized resting-budget flows only when absolutely
required, and fixed the calendar-based alignment qualifier
- **Masked Key Persistence** - Never persist masked provider key
previews to config storage (thanks
[@eyeveil](https://github.com/eyeveil)!)
- **OpenShift Arbitrary UIDs** - Build-time group-0 ownership with no
runtime chown (thanks [@eyeveil](https://github.com/eyeveil)!)
- **Passthrough Virtual Key Attribution** - Passthrough calls via the
Azure `api-key` header now attribute to the virtual key (thanks
[@eyeveil](https://github.com/eyeveil)!)
- **Rerank for Custom Providers** - `/v1/rerank` now works with custom
OpenAI-compatible providers (thanks
[@eyeveil](https://github.com/eyeveil)!)
- **Responses Stream Usage** - Persist stream usage when providers omit
or reuse sequence numbers (thanks
[@eyeveil](https://github.com/eyeveil)!)
- **Wildcard allowed_models Repair** - Repair bare wildcard
`allowed_models` rows that broke admin provider updates (thanks
[@eyeveil](https://github.com/eyeveil)!)
- **Streaming Error Panic** - Nil-safe tracing span lookup prevents
panics on streaming errors (thanks
[@eyeveil](https://github.com/eyeveil)!)
- **Anthropic Tool ID Sanitization** - Sanitize `tool_use`/`tool_result`
ids to Anthropic's charset (thanks
[@Shaik-Sirajuddin](https://github.com/Shaik-Sirajuddin)!)
- **Realtime Transcription Sessions** - Support GA transcription-type
sessions in `POST /v1/realtime/client_secrets` (thanks
[@Shaik-Sirajuddin](https://github.com/Shaik-Sirajuddin)!)
- **Diarized Transcription** - Support `diarized_json` segments and
ElevenLabs speaker passthrough (thanks
[@Shaik-Sirajuddin](https://github.com/Shaik-Sirajuddin)!)
- **Model Discovery** - Skip disabled keys when scheduling
model-discovery fetches (thanks
[@Shaik-Sirajuddin](https://github.com/Shaik-Sirajuddin)!)
- **MCP Timeout Placeholder** - Show the real global default in the MCP
tool execution timeout placeholder (thanks
[@Shaik-Sirajuddin](https://github.com/Shaik-Sirajuddin)!)
- **Redacted Thinking Round-Trip** - Round-trip Anthropic
`redacted_thinking` blocks on the Responses surface (thanks
[@fus3r](https://github.com/fus3r)!)

`finish_reason` in the accumulated streaming response (thanks
[@fus3r](https://github.com/fus3r)!)
- **Gemini Grounded Streaming** - Reset web-search flag when recycling
pooled stream state so `web_search_call` items keep emitting (thanks
[@fus3r](https://github.com/fus3r)!)
- **Bedrock Truncation Signal** - Signal `max_output_tokens` truncation
on the Responses API (thanks
[@jeremym-tanium](https://github.com/jeremym-tanium)!)
- **Bedrock Reasoning Config** - Preserve `reasoning_config` on
cross-provider translation so fallbacks keep extended thinking (thanks

`tool_search` on the Responses path (thanks
[@ws4charlie](https://github.com/ws4charlie)!)

(thanks [@nettee](https://github.com/nettee)!) and serialize compaction
request `input` correctly (thanks

- **additional_tools Support** - Added `additional_tools` message type
support, preserving nested tool types on `/v1/responses`

`/api/dev` prefix
- **Bedrock Error Types** - Surface the AWS exception type
(`X-Amzn-Errortype`) on non-streaming Bedrock error responses instead of
dropping it

## 🔧 Maintenance

- **Hot-Path Performance** - Cached serialization for shared MCP tools,
a direct `OrderedMap` JSON writer, bulk span attribute writes with
cached span pointers, reusable worker delivery timers, retained span
attribute maps, generation-stamped memoization of `GetProvidersForModel`
and `GetModelsForProvider` via the new `gencache` package, sonic-based
JSON responses, and a plugin-log existence check before draining (#6242,
#6241, #5956, #5957, #5657, #6387, #5641, #6224, #6268, #6211)

## 🗄️ Database Migrations

All migrations below are new relative to v1.6.11. Deployments on an
older v1.6.x release should also review the intermediate v1.6.x
changelogs.

**configstore:**

- **add_mcp_client_pending_oauth_config_json_column** - Adds
`pending_oauth_config_json` to `config_mcp_clients`. Reversible: drops
the added column.
- **merge_oauth_token_tables** - Consolidates `oauth_tokens` and
`oauth_user_tokens` into `mcp_oauth_tokens`. **Non-reversible**:
rollback deliberately leaves `mcp_oauth_tokens` in place, because every
OAuth read and write targets it from this migration onward and dropping
it would destroy any token created or refreshed since, forcing every
holder to re-authorize.
- **create_mcp_oauth_flows_table** - Creates `mcp_oauth_flows` to track
in-flight OAuth flows. Reversible: drops the new table.
- **drop_oauth_config_pkce_columns** - Drops CSRF state, PKCE verifier
and `expires_at` from the OAuth config table now that they live on
`mcp_oauth_flows`. **Non-reversible**: forward-only, the dropped values
were per-flow ephemeral and re-adding empty columns would restore
nothing.
- **drop_oauth_config_token_id_column** - Drops `token_id`.
**Non-reversible**: forward-only, it was a pure FK shortcut now
reachable via `(oauth_config_id, auth_mode)`.
- **add_mcp_admin_auth_mode_indexes** - Adds admin partial unique
indexes on `mcp_oauth_tokens` and `mcp_per_user_header_credentials`.
Reversible: drops both indexes.
- **add_mcp_client_token_exchange_json_column** - Adds
`token_exchange_json` to `config_mcp_clients`. Reversible: drops the
added column.
- **add_needs_session_stickiness_column** - Adds
`needs_session_stickiness` to `config_mcp_clients`. Reversible: drops
the added column.
- **add_bedrock_endpoints_columns** - Adds Bedrock VPC endpoint columns
to the keys table. Reversible: drops the added columns.
- **add_cost_per_request_pricing_column** - Adds `cost_per_request` to
model pricing. Reversible: drops the added column.
- **add_notifications_table** - Creates the `notifications` table for
the dashboard notification center. Reversible: drops the table.
- **add_batch_jobs_table** - Creates `batch_jobs` with a unique
`(provider, batch_id)` identity index, a sweeper scan index and a
runner-id index. Reversible: drops the table.
- **add_image_megapixel_tier_pricing_columns** - Adds the five
`output_cost_per_image_above_{4,8,16,32,64}_megapixels` columns to model
pricing. Reversible: drops the added columns.
- **add_input_cost_per_query_column** - Adds `input_cost_per_query` to
model pricing for rerank. Reversible: drops the added column.
- **add_ultrafast_pricing_columns** - Adds the four `*_ultrafast` token
rate columns to model pricing. Reversible: drops the added columns.
- **add_image_size_quality_pricing_columns** - Adds the 14 per-size and
size+quality image output rate columns to model pricing. Reversible:
drops the added columns.
- **add_batch_jobs_attribution_columns** - Adds `user_id`, `team_id`,
`customer_id` and `source_log_id` to `batch_jobs` plus a `user_id`
index. Reversible: drops the index and the four columns.

**logstore:**

- **logs_add_guardrail_debug_column** - Adds `guardrail_debug` to logs.
Reversible: drops the added column.
- **mcp_tool_logs_add_redaction_mapping_column** - Adds the redaction
mapping column to MCP tool logs. **Non-reversible**: rollback is a no-op
because dropping the column would permanently destroy reveal data for
already-redacted MCP logs.
- **logs_add_user_agent_column** - Adds user agent and app columns,
their indexes, and a `UserAgentMapping` table. Reversible: drops the
indexes and the mapping table.
- **mcp_tool_logs_add_user_agent_column** - Adds user agent and app
columns plus indexes to MCP tool logs. Reversible: drops both indexes
and the `app` column.
- **logs_recreate_matviews_with_app_column** - Recreates the log
materialized views to include the user agent and app columns. Rollback
is a no-op because `ensureMatViews` recreates them on next startup.
- **mcp_tool_logs_add_endpoint_columns** - Adds `source`, `decision`,
`app_key` and `device_id` to MCP tool logs. Reversible: drops all four
columns.
- **mcp_tool_logs_add_plugin_logs_column** - Adds `plugin_logs` to MCP
tool logs. Reversible: drops the added column.
- **logs_add_video_edit_input_column** - Adds `video_edit_input` to
logs. Reversible: drops the added column.
- **logs_add_upstream_and_overhead_latency_columns** - Adds
`upstream_latency` and `overhead_latency` to logs. Reversible: drops
both columns.
- **logs_add_batch_debug_column** - Adds `batch_debug` to logs.
Reversible: drops the added column.
- **logs_add_cost_breakdown_columns** - Adds `input_cost`, `output_cost`
and `additional_cost` to logs. Reversible: drops the three columns.
- **logs_recreate_matviews_with_cost_breakdown** - Marks the hourly
matview for rebuild with the cost split columns; `repairMatViewShapes`
drops and recreates `mv_logs_hourly` on the next startup. Rollback is a
no-op because `ensureMatViews` recreates it on next startup.
- **logs_add_overhead_breakdown_column** - Adds `overhead_breakdown` to
logs. Reversible: drops the added column.

<Warning>
**High-throughput deployments: run the logstore migrations during a
low-activity window.**

Every logstore migration above alters `logs` or `mcp_tool_logs`, the two
highest-insert tables in Bifrost, and several also build indexes on
them. On a busy instance the index builds hold locks that block
concurrent log inserts for the duration of the build, and the matview
recreations rebuild against the full table. Schedule the upgrade for a
low-traffic period, or expect elevated log-write latency and possible
request-path backpressure while the migrations run.
</Warning>

<Warning>
`merge_oauth_token_tables`, `drop_oauth_config_pkce_columns` and
`drop_oauth_config_token_id_column` transform or remove existing OAuth
state and cannot be rolled back. Take a database backup before
upgrading, and do not roll the binary back past this release once the
migration has run.
</Warning>

…lls when resolved by sweeper (maximhq#6474)

## Summary

Surfaces batch accounting data (model, token usage, and cost) in the logs table UI, and ensures `batch_debug` is included in list queries so that data is available for display. Batch log entries that lack a top-level model, token usage, or cost now fall back to values derived from the batch debug accounting breakdowns. Additionally, the server version is propagated into the context at bootstrap so that batch accounting settlement logs carry a `UserAgent` field.

## Changes

- Added `BifrostContextKeyRuntimeVersion` context key and set it at server bootstrap so the runtime version is available throughout the request lifecycle.
- Added `userAgentFromContext` helper that reads the runtime version from context and builds a `"bifrost/<version>"` user agent string, falling back to `"bifrost"`.
- Passed the resolved user agent into `buildAggregateLog` and set it as `UserAgent` on the resulting log entry during batch accounting settlement.
- Added `batch_debug` to the `listSelectColumns` query so batch debug data is returned when listing log entries.
- Added a `batchAccountingDisplay` helper that aggregates model and token usage across `batch_debug.accounting.model_breakdowns`, returning `"mixed"` when multiple models are present.
- Model and token usage columns now fall back to `batchAccountingDisplay` when the top-level fields are absent.
- The cost column now renders the settled batch cost (from `batch_debug.accounting.cost`) with a tooltip explaining it is billed once, rather than showing `N/A`.
- Replaced `batchDebug`-gated UI logic with an `isBatch` flag derived from the log object type, so batch cancel and list operations are handled correctly even when `batch_debug` is absent.
- Batch ID and status in the detail view now fall back to the raw provider response payload when `batch_debug` is not present.
- Moved the status badge from the summary header section into the Details tab alongside the batch ID, so it is consistently sourced from either `batch_debug` or the raw response.

## Type of change

- [ ] Bug fix
- [x] Feature
- [ ] Refactor
- [ ] Documentation
- [ ] Chore/CI

## Affected areas

- [x] Core (Go)
- [x] Transports (HTTP)
- [ ] Providers/Integrations
- [ ] Plugins
- [x] UI (React)
- [ ] Docs

## How to test

1. Submit a batch request and wait for it to settle.
2. Open the logs table and locate the batch log entry.
3. Verify the model column shows the correct model name (or `"mixed"` for multi-model batches).
4. Verify the token usage column shows aggregated prompt, completion, and total tokens.
5. Verify the cost column shows the settled batch cost with a tooltip reading "Settled cost of this batch, billed once." instead of `N/A`.
6. Open a batch cancel or batch list log entry and verify the Details tab and batch ID/status fields render correctly without `batch_debug`.

```sh
# Core/Transports
go test ./...

# UI
cd ui
pnpm i || npm i
pnpm build || npm run build
```

## Screenshots/Recordings

Before: Model, token usage, and cost columns showed `N/A` for settled batch log entries. Batch cancel and list log entries did not render a Details tab or batch status.

After: All three columns display values derived from `batch_debug` accounting data, with a tooltip on the cost cell. Batch cancel and list entries correctly show or hide the Details tab based on object type.

## Breaking changes

- [ ] Yes
- [x] No

## Security considerations

No new auth, secrets, PII, or sandboxing concerns introduced.

## Checklist

- [ ] I read `docs/contributing/README.md` and followed the guidelines
- [ ] I added/updated tests where appropriate
- [ ] I updated documentation where needed
- [ ] I verified builds succeed (Go and UI)
- [ ] I verified the CI pipeline passes locally if applicable

<Note>
v2.0.0 is the first stable release on the 2.0 line. This changelog rolls
up `2.0.0-prerelease1` (based on
[v1.6.3](https://docs.getbifrost.ai/changelogs/v1.6.3)),
`2.0.0-prerelease2`, `2.0.0-prerelease3` and the final release window,
so it is the complete delta for a deployment upgrading from any v1.6.x
release. Fixes that also shipped on the v1.6.x line after v1.6.3 are
listed once here.
</Note>

<Warning>
**Breaking changes.** Read the [v2.0.0 migration
guide](https://docs.getbifrost.ai/migration-guides/v2.0.0) before
upgrading.

- **Custom plugin downloads are SSRF-protected** - a plugin `path`
pointing at an http(s) URL is rejected if it resolves to a loopback,
private, CGNAT, link-local or otherwise non-public address, and every
custom plugin path is re-verified on each restart, including ones
defined in `config.json`.
- **Custom plugin create and update require admin authentication** -
`POST /api/plugins` and `PUT /api/plugins/{name}` reject a custom `path`
when the caller only got through because dashboard auth is disabled or
unconfigured.
- **Governance APIs moved under `/api/governance/*`** - `/api/teams`,
`/api/users`, `/api/roles`, `/api/audit-logs` and other top-level
governance paths moved under one namespace; Team and User lists use
`limit`/`offset` pagination. Routing rules and the complexity analyzer
moved from `/api/governance/*` to `/api/routing/rules` and
`/api/routing/complexity-analyzer-config`; the old paths remain as
deprecated aliases.
- **`HTTPTransportPreHook` now runs after authentication** - the
pipeline is `HTTPTransportPreAuthHook -> auth -> HTTPTransportPreHook ->
handler`. Plugins that inject a credential (`x-bf-vk`, `Authorization`,
`x-api-key`) must move that work to the new `HTTPTransportPreAuthHook`,
and Go plugins implementing `HTTPTransportPlugin` must add the method
(`.so` plugins that predate it are skipped for that phase).
- **Legacy telemetry attributes removed** - the `gen_ai.*`-namespaced
Bifrost-internal span attributes,
`gen_ai.usage.prompt_tokens`/`completion_tokens`, the nanosecond
`time_to_first_token` attribute and `x-bf-prom-*` request-header
Prometheus dimensions are gone from the OTel and Prometheus connectors.
Dashboards should read the `bifrost.*` keys and `time_to_first_chunk`.
- **Gemini tool preference** - a Gemini API request carrying both
function declarations and Google Search without
`include_server_side_tool_invocations` now keeps the function
declarations and drops Google Search (previously the opposite). Set
`include_server_side_tool_invocations: true` to send both on Gemini 3
models. Vertex is unaffected.
</Warning>

## ✨ Features

- **Batch Accounting** - Provider batch jobs are tracked in a new
`batch_jobs` table and settled asynchronously: results are priced per
model from catalog batch rates (0.5 default ratio) on the `/results`
path, one aggregate cost log is written idempotently with the creating
request's identity, a background sweeper with ownership fencing
re-drives jobs that timed out, settled usage is charged exactly once to
the creating user's budgets and rate limits (including unscoped virtual
key budgets on model-less batch-create requests), mixed-model batch rows
are repriced during cost recalculation, and the log detail view shows a
Batch Details block with per-state request counts and the settled cost
(maximhq#5291, maximhq#5292, maximhq#5293, maximhq#5294, maximhq#5295, maximhq#5296, maximhq#6109, maximhq#6121, maximhq#6376, maximhq#6410,
maximhq#6474, maximhq#6505)
- **Claude-on-Vertex Batches** - Vertex batch jobs route Anthropic
models to `publishers/anthropic/...`, build Claude-on-Vertex JSONL
instances, round-trip `custom_id`, and preserve `tools`, `toolConfig`,
`cachedContent`, `labels` and `display_name` on Gemini/Vertex batch
requests (maximhq#5368)
- **Input / Output Cost Split** - Every log carries `input_cost`,
`output_cost` and `additional_cost` (guardrails, semantic cache, MCP)
next to the total, across the RDB, ClickHouse, matviews, recalculation
and the quota API; speech, transcription and OCR usages carry
`BifrostCost`; the log detail view shows the split with per-category
detail (maximhq#6511)
- **Bifrost Overhead Latency** - `upstream_latency` and
`overhead_latency` are recorded on every log, aggregated (avg, p90, p95,
p99) in the dashboard's new Bifrost Overhead chart and shown in the log
detail view; the overhead is decomposed by span self-time into
serialization, conversion, plugins, middleware, key selection, queue
wait, networking, client delivery and scheduling buckets (including
streaming per-chunk parse, conversion and backpressure and the worker
hand-off), persisted to `overhead_breakdown` and rendered as a stacked
bar in the log detail view; a `bifrost_overhead_latency_microseconds`
histogram is exported to Prometheus and OpenTelemetry and
`upstream_latency_ms`/`overhead_latency_ms` tags to Maxim, while
breakdown spans are kept out of observability connectors (maximhq#5533, maximhq#5534,
maximhq#5535, maximhq#6345, maximhq#6388, maximhq#6389, maximhq#6433, maximhq#6470, maximhq#6495)
- **Notification Center** - Role-targeted dashboard notifications stored
in the database, delivered over WebSocket and surfaced in a topbar tray
via `GET/POST /api/notifications` (maximhq#6207, maximhq#6227, maximhq#6324)
- **Topbar and Responsive Dashboard** - Persistent topbar with page
titles, theme toggle, external links, user menu and version; responsive
layouts across all views with truncation and tooltips for long values
and icon-only buttons; version-skew detection with an auto-reloading
upgrading screen (maximhq#6196, maximhq#6105, maximhq#6126, maximhq#6204, maximhq#6232, maximhq#6330, maximhq#6370,
maximhq#6476, maximhq#6485, maximhq#6493)
- **Video Edits** - `POST /v1/videos/edits` applies prompt-driven edits,
upscaling and background removal to an existing video supplied as bytes,
a URL or a provider video ID, on OpenAI and Runware (maximhq#6270)
- **Runware Chat, Catalog and Media Operations** - Chat completions,
streaming and Responses via Runware's OpenAI-compatible endpoint,
`ListModels` from the curated catalog, image upscale via
`/v1/images/edits` (`type=upscale`), image-to-3D and async 3D generation
via `/v1/videos` (`type=3d`), provider-reported per-task cost, and a raw
`/runware_passthrough` route (maximhq#6260, maximhq#6372, maximhq#6208, maximhq#6075)
- **JSON Image Edits** - `POST /v1/images/edits` accepts JSON bodies
with URL or base64 images and typed extra params in addition to
multipart (maximhq#6418)
- **OpenAI Ultrafast Service Tier** - `service_tier: "ultrafast"` is
forwarded only to models that support it and billed at dedicated
ultrafast rates, with matching custom pricing override fields (maximhq#6396,
maximhq#6399)
- **Service Tier on Logs** - Logs record the tier actually served,
including Anthropic's `service_tier` from `message_start` on streams,
with a Service Tier column and detail field so repricing uses the served
tier (maximhq#6233, maximhq#6236)
- **Pricing Fields** - New per-request flat fee (`cost_per_request`),
megapixel-based image tiers (4/8/16/32/64 MP), per-size and joint
size+quality image rates for `gpt-image-1`-style models, and
`input_cost_per_query` for rerank flow through datasheet sync, the cost
engine, custom overrides, the API and the UI override form; upscale
output resolution is backfilled from `target`/`factor` on Replicate so
tiered rates bill the real output size (maximhq#6079, maximhq#6082, maximhq#6083, maximhq#6379,
maximhq#6380)
- **Model Catalog Pricing and Overrides** - Pricing data in the model
catalog (thanks [@johnbrett](https://github.com/johnbrett)!), with
resolved pricing overrides exposed on `/api/models/details` and on
catalog rows, shown in the dashboard (maximhq#6055, maximhq#6056, maximhq#6058)
- **Typed Embeddings on Bedrock** - Titan V2 `embeddingTypes` and Cohere
`embedding_types` on Converse, the native invoke route and LangChain
`BedrockEmbeddings` (maximhq#6381)
- **Rerank Upgrades** - Structured JSON documents, `return_documents`,
`next_token` pagination, caller document IDs preserved in every result,
Cohere-shaped errors, cross-provider responses converted back to the
caller's wire shape, and `/genai/v1/rank` served cross-provider (maximhq#6328,
maximhq#6301, maximhq#6432)
- **OpenRouter Speech, Transcription and Embeddings** - TTS and STT
through OpenRouter's audio endpoints, and embedding models included in
`ListModels` (maximhq#5734, maximhq#6264)
- **Grok on Bedrock Mantle** - `xai.` models route through the
`openai/v1` Mantle path (maximhq#6022)
- **Gemini 3 Thinking Levels** - A per-model `thinkingLevel` support
table clamps requested levels to the rungs each model implements;
`reasoning_effort: "none"` sets the model's floor level instead of
zeroing `thinkingBudget` (maximhq#6280)
- **Datasheet-Backed Compatibility** - Anthropic, Bedrock, Cohere and
Gemini request shaping (adaptive thinking, native effort,
disable-reasoning, mid-conversation system turns, computer-use and
text-editor tool generations, default max output tokens, tool
validation) is resolved from model capabilities instead of hardcoded
model-name checks (maximhq#6281, maximhq#6492)
- **Reasoning Effort None** - Models that reason by default but do not
support reasoning with tool calls get `reasoning.effort: "none"` when
they advertise `supports_none_reasoning_effort`, instead of losing
`reasoning` entirely (maximhq#6293)
- **HTTP Transport Pre-Auth Hook** - New `HTTPTransportPreAuthHook`
plugin phase runs before transport authentication so plugins can inject
credentials such as `x-bf-vk`; a `virtual-key-from-config` native plugin
example ships alongside it (maximhq#6375, maximhq#6373)
- **Plugin Inject Limits** - Per-plugin `semaphore_size` and
`inject_timeout` on `PluginConfig` bound observability `Inject` calls so
a hung connector releases its slot (maximhq#6341)
- **Harness Session Autodetection** - Claude Code, Codex CLI and
OpenCode session headers populate the session ID when `x-bf-session-id`
is absent (maximhq#6333)
- **Auth and Model Check Skip Paths** - Context keys let trusted
internal callers bypass auth resolution, and let evaluate-only requests
such as `/inspect` bypass the virtual key provider and model allowlists
while budgets and rate limits still apply (maximhq#6124, maximhq#6479)
- **Passthrough Encoding Negotiation** - Forwarded `Accept-Encoding` is
filtered to decodable codecs (gzip, deflate, brotli, zstd; gzip and
identity for streams) and chained content encodings are decoded (maximhq#6360)
- **Routing Plugin** - Routing rules and the complexity router live in a
dedicated `routing` plugin that runs after governance so rules evaluate
on the fully stamped context; endpoints moved to `/api/routing/rules`
and `/api/routing/complexity-analyzer-config` with deprecated
`/api/governance/*` aliases; complexity routing now reads the text of
mixed text+image turns (maximhq#6144, maximhq#6145, maximhq#6146, maximhq#6147, maximhq#6253)
- **Dimension Scope Ceiling** - Grouped log analytics (rankings,
histograms, key pairs) are bounded to the customer, team, business unit,
user and virtual key ids the caller may see (maximhq#6262)
- **MCP Per-User OAuth and Token Exchange** - MCP clients can hold
per-user OAuth credentials and per-user headers, configurable from
`config.json` as well as the UI, with a documented shared vs
per-identity token lookup contract, `oauth_config.resource` (RFC 8707),
VK/Users filters on the OAuth Grants and MCP Auth Sessions sidebars and
one shared create/install client form; `token_exchange` gains
`use_idp_credentials` to reuse SSO login app credentials for providers
such as Microsoft Entra ID (`client_id` becomes optional) and combines
`offline_access` with `<audience>/.default` for Entra OBO; shared-OAuth
clients show `needs_reauth` when their token row is invalidated,
`Reauthorize` is limited to shared clients, the OAuth flow claim is
atomic against concurrent reauth, stored scopes survive a decode
failure, and credential caches propagate cancellation and version their
entries (maximhq#6068, maximhq#6069, maximhq#6078, maximhq#6411, maximhq#6428, maximhq#6429, maximhq#6504)
- **MCP Connection Lifecycle and Tool Discovery** - Discovered tools
persist and resync uniformly across all client types through a
hash-gated core callback, surviving restarts and propagating across a
cluster; connections use make-before-break reconnects with ephemeral
clients rebuilt across the whole connect+init retry, last-known tool
maps preserved, connect attempts bound to entry identity and background
reconnects deduped; `needs_session_stickiness` is pinned across
`config.json` reconciliation; updating static headers on a sticky client
pre-flight verifies the new credential and swaps it onto the live
connection, per-call shared-credential clients refresh tools
synchronously, and a failed enable parks the client at `Disabled` so it
can be retried; the global `tool_sync_interval` hot-reloads and re-times
running checkers; state badges render with spaces and the `disconnected`
filter bucket is now `unstable` (maximhq#6409, maximhq#6430, maximhq#6431, maximhq#6483, maximhq#6502)
- **Air-Gapped MCP Catalog** - `mcp_library_sync_interval: 0` disables
catalog sync and `file://` URLs load the MCP server library from disk
(maximhq#6195)
- **MCP Log Redaction and Plugin Logs** - MCP tool logs carry redaction
mappings and plugin logs (maximhq#5744, maximhq#5746)
- **Splunk Connector Configuration** - `config.schema.json`, Helm values
and dashboard entries for the Splunk HEC observability connector (maximhq#6296,
maximhq#6091, maximhq#6099)
- **Helm Broker Clustering** - `bifrost.cluster.type: broker` with
broker address, port and TLS settings alongside the existing mesh
transport (maximhq#6398)
- **HTTP/2 Ping Interval in the UI** - Provider network configuration
exposes `http2_ping_interval_in_seconds` (maximhq#6228)
- **Status Code Badges** - Error and passthrough logs show the upstream
HTTP status code in the log detail header (maximhq#5536)
- **Server-Side Tool Calls in Logs** - `web_search_call`,
`code_interpreter_call` and similar Responses items render their full
payload in the log detail view (maximhq#6475)
- **Gemini Server-Side Tool Calls** - Gemini `toolCall`/`toolResponse`
parts surface as `web_search_call` items with their own call ID and
queries, unmapped tool types are preserved on the native round-trip, and
each `thoughtSignature` appears exactly once on replay (maximhq#6071)
- **Bedrock VPC Endpoints** - AWS Bedrock keys can target VPC endpoints
(maximhq#6064)
- **W3C Trace ID Propagation** - Requests carry a W3C trace ID on the
context (maximhq#5945)
- **Durable Background Jobs** - New `sidekiq` background-job table,
store methods, and runner with recovery and reaper; cost recalculation
migrated to a durable, resumable and cancellable job with polling
instead of SSE (maximhq#5800, maximhq#5801)
- **Separate OTEL Metrics Pipeline** - The OTEL collector supports a
metrics tab independent of traces, plus separate headers for traces and
metrics (maximhq#5939, maximhq#5940)
- **Grouped Logs View** - The logs table groups fallback chains under
expandable roots backed by the new `roots_only` filter with child
aggregates, and the model catalog persists tab, search and provider in
the URL (maximhq#5522, maximhq#5737, maximhq#6059)
- **User Agent and App Attribution** - Logs and MCP tool logs record
user agent, app, source, decision, app key and device ID, with custom
user-agent mapping and dashboard dimension rankings; MCP tool logs
observed by the Bifrost Edge agent can be ingested with device, app key,
decision and source attribution
- **S3 Log Export Metadata** - Additional metadata is written alongside
S3 log exports (maximhq#6070)
- **Matview Maintenance Off Switch** - `matview_refresh_interval`
accepts `"off"` to disable logstore matview maintenance entirely (thanks
[@jeremym-tanium](https://github.com/jeremym-tanium)!) (maximhq#5693)
- **Video Request Info in Logs UI** - Video requests surface their
details in the logs UI (maximhq#5946)
- **Shell Rewriter Hook** - The UI handler exposes a `ShellRewriter`
hook for pre-hydration HTML rewriting (maximhq#5807)
- **Custom Branding** - Logo and icon branding support with an OSS
fallback stub, cached in localStorage to prevent a logo flash on load
(maximhq#5806, maximhq#6096)
- **User Assignment on Virtual Keys** - Users can be assigned from the
virtual key sheet (maximhq#5863)
- **Quarterly Budgets** - Quarterly budget windows with a configurable
fiscal year start for customers and virtual key provider configs,
surfaced in budget labels (maximhq#5996, maximhq#5997, maximhq#5999, maximhq#6115, maximhq#6116)
- **Sarvam AI Provider** - Added Sarvam AI as a first-class provider
with chat, text-to-speech, and speech-to-text support (thanks
[@Purvi09](https://github.com/Purvi09)!)
- **ElevenLabs Sound Effects** - Added text-to-sound generation support
via `/v1/sound-generation` (thanks
[@SecretSun](https://github.com/SecretSun)!)
- **Bedrock Project Scoping** - Added optional `project_id` to Bedrock
and Bedrock Mantle key configs with per-alias overrides for Bedrock,
Bedrock Mantle, and Vertex, plus UI support
- **Trace Redaction** - Phase-scoped redaction and revealing, transient
redaction data field for guardrails, and trace content redaction before
connector export
- **Audit Log Object Storage** - S3/GCS object storage config schema for
audit log archival
- **Alerting Configuration** - Alerting schema in `config.schema.json`
with declarative channels and CEL-based rules, Helm chart support, and
enterprise fallback pages
- **Canonical Model Names** - Dashboard model rankings now show
canonical model names instead of inference-profile IDs (thanks
[@satyamkrishna](https://github.com/satyamkrishna)!)
- **OAuth2 Hardening** - Allowlist for private-use redirect URI schemes
(RFC 8252 §7.1) and a `shouldSweep` gate on the OAuth2 sweep worker
- **Mirrored Schema Support** - `schema_url` / `BIFROST_SCHEMA_URL` for
mirrored schema locations in isolated deployments
- **Vertex Single-Region Config** - Enforce single-region configuration
in Vertex key config
- **Helm Chart Updates** - `bifrost.alerting`, audit-log object storage,
`postgresql.external.port` string support, and
`bifrost.mcp.toolGroups[*].id`
- **ChatGPT Passthrough** - Added a ChatGPT passthrough route on the
OpenAI integration with dedicated request handling
- **Edge Fallback Pages** - Added fallback pages for Bifrost Edge
control views (config, devices, inventory) backed by governance resolver
support
- **Agent Handover View** - Added an agent handover page with seeded
end-to-end data support
- **First-Time Setup Token** - A setup token gates first-time setup so a
fresh deployment is not open to the world, and the onboarding checklist
is back, completing its dashboard auth step on SSO deployments (maximhq#5759,
maximhq#5784, maximhq#6322)

## 🐞 Fixed

- **Structured Output Schema Order** - `response_format` JSON schemas
are forwarded byte-for-byte to OpenAI, Anthropic, Bedrock, Gemini and
Cohere so the model generates fields in the caller's declared order
instead of a re-sorted one (maximhq#6235)
- **Thinking Block Typing on Streams** - Reasoning items carrying both
an encrypted payload and a visible summary open as `thinking` blocks
instead of `redacted_thinking` (maximhq#6292)
- **Replayed Thinking Blocks via `bedrock/` Prefix** - Content-less
`tool_result` blocks are kept, interleaved block order is preserved,
`incomplete` maps to `error` on Converse, and pending reasoning is
consumed by its owning item, so multi-turn tool use no longer wedges
(maximhq#6346)
- **Gemini 400s on Claude Code Traffic** - Trailing assistant prefills
are trimmed and mid-conversation system turns are inlined for
Gemini/Vertex; `extra_fields` is echoed on `/anthropic/v1/messages`
(maximhq#6363)
- **Bedrock Tool Use IDs** - IDs longer than 64 characters or outside
Bedrock's charset (such as Gemini thought-signature IDs) are aliased
deterministically on both `tool_use` and `tool_result` (maximhq#6300)
- **Azure Responses Stream Errors** - Terminal `error` and
`response.failed` events inside an already-open HTTP 200 SSE stream are
surfaced as errors with their nested type, code and message (thanks
[@dani29](https://github.com/dani29)!) (maximhq#6302)
- **GenAI SSE Heartbeats** - GenAI streams delimit heartbeat comments so
Google SDK clients preserve the following event, while older openai-go
clients keep the bare heartbeat (thanks
[@dani29](https://github.com/dani29)!) (maximhq#6252)
- **OpenCode max_tokens** - `max_tokens` is preserved for
OpenCode-compatible chat endpoints (thanks
[@Alex-wangyang](https://github.com/Alex-wangyang)!) (maximhq#6458)
- **HuggingFace Streaming Usage** - HuggingFace is no longer listed as
omitting the `[DONE]` marker, and `stream_options.include_usage`
defaults on its chat streaming path, so streamed calls stop reporting
zero tokens and zero cost (thanks
[@elliottrabac](https://github.com/elliottrabac)!) (maximhq#6478)
- **Provider Key Name on Update** - A key PUT that omits `name` no
longer clears it, and already-exists errors keep their constraint detail
(thanks [@cpsc](https://github.com/cpsc)!) (maximhq#6417)
- **Bedrock Mantle Streaming** - Bedrock Mantle is registered in
`ProviderSendsDoneMarker` so streams end after `finish_reason` (maximhq#6021)
- **URL-Sourced Files and Images** - `gs://` URIs go to Gemini/Gemma as
`fileData.fileUri` and are read from Cloud Storage for Claude-on-Vertex,
`s3://` references go to Bedrock Converse as `s3Location`, Bedrock
rerank synthesizes the foundation-model ARN from a bare model ID, OpenAI
file blocks keep `file_url`, non-http schemes pass through on the OpenAI
and native-Anthropic paths, and Gemini always emits a candidate with its
finish reason and drops payload-free parts (maximhq#6239)
- **Together and Alias Pricing** - The management catalog resolves
runtime provider `together` to the datasheet identity and prices
configured aliases through their target model (thanks
[@dani29](https://github.com/dani29)!) (maximhq#6257, maximhq#6320)
- **Redis Vector Store TAG Escaping** - All RediSearch special
characters are escaped in TAG query values (thanks
[@AdityaPainuli](https://github.com/AdityaPainuli)!) (maximhq#5351)
- **MCP Tool Sync Interval Corruption** - Toggling an MCP client's
enable/disable switch no longer corrupts `tool_sync_interval`; the value
is a whole number of minutes, negative values are rejected instead of
silently disabling sync, and re-enabling a per-call client restarts its
discovery cycle (maximhq#6409, maximhq#6502)
- **MCP Tool Map Staleness** - `SetClientTools` replaces the in-memory
tool map instead of merging, so tools removed upstream leave memory once
the database has dropped them (maximhq#6484)
- **SSE Reconnect Identity** - `OnConnectionLost` on SSE MCP clients is
gated on connection identity so a stale connection cannot tear down its
replacement
- **Connector Header Redaction** - `Authorization`, `x-api-key`,
Cloudflare Access and AWS ALB OIDC headers are redacted before export to
every observability backend (maximhq#6371)
- **Vertex Mixed Tools** - Vertex AI accepts function declarations and
Google Search in the same request without
`includeServerSideToolInvocations`, and search localization via
`retrievalConfig.latLng` is preserved (maximhq#6066)
- **Gemini Tool Preference** - When tool combination is disabled,
function declarations win over Google Search so the model can still call
the caller's tools (maximhq#6065)
- **Bedrock Stop Reasons** - Bedrock `content_filter` and
`guardrail_intervened` stop reasons map to `incomplete` status with a
`content_filter` reason
- **Encrypted Reasoning on Compaction** - The fail-soft that strips
`encrypted_content` before retrying a rejected request also covers
`/v1/responses/compact` and count-tokens requests, and recognizes
Anthropic's `redacted_thinking` rejection (maximhq#6041, maximhq#5960)
- **DAC-Scoped VK Reads** - `from_memory` virtual key reads are blocked
for DAC-scoped callers
- **Path Normalization Auth Bypass** - Fixed a path normalization flaw
that allowed auth to be bypassed (maximhq#5763)
- **Minimal Reasoning Effort on GPT-5 Models** - `reasoning_effort:
"minimal"` is preserved for GPT-5-family OpenAI models instead of being
downgraded to `low` (thanks [@jitokim](https://github.com/jitokim)!)
(maximhq#6046)
- **Gemini Truncated Response Finish Reason** - Truncated Gemini
responses report `MAX_TOKENS` instead of `OTHER` (thanks
[@AdityaPainuli](https://github.com/AdityaPainuli)!) (maximhq#5979)
- **Null Tool-Call Function Name on Streaming** - Streaming continuation
deltas no longer materialize an absent tool-call function name as `null`
(thanks [@AdityaPainuli](https://github.com/AdityaPainuli)!) (maximhq#5966)
- **Bedrock Document Uploads** - Fixed Bedrock file handling in
inference so office and PDF documents sent as OpenAI `type: "file"` are
accepted (maximhq#5947)
- **xAI Usage Cost** - Fixed USD cost ticks for xAI usage (maximhq#5950)
- **Governance List-Models Call** - Budgets and rate limits no longer
trigger a list-models call (maximhq#6051)
- **Realtime Response Create Input** - Guarded `response.create` input
(maximhq#6050)
- **Governance Rate-Limit Reset CPU** - Guards against invalid reset
timeouts, parallelized resting-budget flows only when absolutely
required, and fixed the calendar-based alignment qualifier
- **Masked Key Persistence** - Never persist masked provider key
previews to config storage (thanks
[@eyeveil](https://github.com/eyeveil)!)
- **OpenShift Arbitrary UIDs** - Build-time group-0 ownership with no
runtime chown (thanks [@eyeveil](https://github.com/eyeveil)!)
- **Passthrough Virtual Key Attribution** - Passthrough calls via the
Azure `api-key` header now attribute to the virtual key (thanks
[@eyeveil](https://github.com/eyeveil)!)
- **Rerank for Custom Providers** - `/v1/rerank` now works with custom
OpenAI-compatible providers (thanks
[@eyeveil](https://github.com/eyeveil)!)
- **Responses Stream Usage** - Persist stream usage when providers omit
or reuse sequence numbers (thanks
[@eyeveil](https://github.com/eyeveil)!)
- **Wildcard allowed_models Repair** - Repair bare wildcard
`allowed_models` rows that broke admin provider updates (thanks
[@eyeveil](https://github.com/eyeveil)!)
- **Streaming Error Panic** - Nil-safe tracing span lookup prevents
panics on streaming errors (thanks
[@eyeveil](https://github.com/eyeveil)!)
- **Anthropic Tool ID Sanitization** - Sanitize `tool_use`/`tool_result`
ids to Anthropic's charset (thanks
[@Shaik-Sirajuddin](https://github.com/Shaik-Sirajuddin)!)
- **Realtime Transcription Sessions** - Support GA transcription-type
sessions in `POST /v1/realtime/client_secrets` (thanks
[@Shaik-Sirajuddin](https://github.com/Shaik-Sirajuddin)!)
- **Diarized Transcription** - Support `diarized_json` segments and
ElevenLabs speaker passthrough (thanks
[@Shaik-Sirajuddin](https://github.com/Shaik-Sirajuddin)!)
- **Model Discovery** - Skip disabled keys when scheduling
model-discovery fetches (thanks
[@Shaik-Sirajuddin](https://github.com/Shaik-Sirajuddin)!)
- **MCP Timeout Placeholder** - Show the real global default in the MCP
tool execution timeout placeholder (thanks
[@Shaik-Sirajuddin](https://github.com/Shaik-Sirajuddin)!)
- **Redacted Thinking Round-Trip** - Round-trip Anthropic
`redacted_thinking` blocks on the Responses surface (thanks
[@fus3r](https://github.com/fus3r)!)
- **Streaming Accumulation** - Preserve citation annotations and
`finish_reason` in the accumulated streaming response (thanks
[@fus3r](https://github.com/fus3r)!)
- **Gemini Grounded Streaming** - Reset web-search flag when recycling
pooled stream state so `web_search_call` items keep emitting (thanks
[@fus3r](https://github.com/fus3r)!)
- **Bedrock Truncation Signal** - Signal `max_output_tokens` truncation
on the Responses API (thanks
[@jeremym-tanium](https://github.com/jeremym-tanium)!)
- **Bedrock Reasoning Config** - Preserve `reasoning_config` on
cross-provider translation so fallbacks keep extended thinking (thanks
[@Purvi09](https://github.com/Purvi09)!)
- **Anthropic tool_search** - Forward and rebuild server-side
`tool_search` on the Responses path (thanks
[@ws4charlie](https://github.com/ws4charlie)!)
- **OpenAI Responses Input** - Strip `role` from non-message input items
(thanks [@nettee](https://github.com/nettee)!) and serialize compaction
request `input` correctly (thanks
[@mcclurmc](https://github.com/mcclurmc)!)
- **additional_tools Support** - Added `additional_tools` message type
support, preserving nested tool types on `/v1/responses`
- **Plugin Stream Errors** - Emit structured plugin stream errors on
integration routes (thanks [@jeffhos](https://github.com/jeffhos)!)

max reasoning effort
- **Anthropic Costing** - Correct inference geo cost and cache rate for
fast mode
- **SecretVar Parsing** - Parse `SecretVar` JSON with `ref`/`env_var`
fields even when `value` is absent
- **Telemetry** - Forward request id and trace id, reduce metrics
cardinality explosion risk, and send status codes on OTEL metrics

- **API Auth Bypass** - Stopped `/api/devices` bypassing auth via the
`/api/dev` prefix
- **Bedrock Error Types** - Surface the AWS exception type
(`X-Amzn-Errortype`) on non-streaming Bedrock error responses instead of
dropping it

## 🔧 Maintenance

- **Hot-Path Performance** - Cached serialization for shared MCP tools,
a direct `OrderedMap` JSON writer, bulk span attribute writes with
cached span pointers, reusable worker delivery timers, retained span
attribute maps, generation-stamped memoization of `GetProvidersForModel`
and `GetModelsForProvider` via the new `gencache` package, sonic-based
JSON responses, and a plugin-log existence check before draining (maximhq#6242,
maximhq#6241, maximhq#5956, maximhq#5957, maximhq#5657, maximhq#6387, maximhq#5641, maximhq#6224, maximhq#6268, maximhq#6211)
- **Go Toolchain** - Modules build with Go 1.26.6 and the Nix flake pins
1.26.7 (maximhq#6269, maximhq#6385)
- **Dependency Upgrades** - Dependabot updates across all modules,
newman 6.2.2 with pinned transitive overrides, module path fixes and
`openai_config` referenced from every provider config schema (maximhq#6040,
maximhq#5864, maximhq#6267, maximhq#6305, maximhq#6275)
- **Test Coverage** - vLLM instances provisioned on RunPod in the
release pipeline, Runware harness coverage including `/v1/images/edits`
and `/v1/videos`, batch and pricing-override lifecycle harness cases, an
Anthropic `message_start` usage regression test, LangChain rerank and
embedding integration tests, and e2e fixes for dashboard auth, budget
reset and MCP state (maximhq#5541, maximhq#6303, maximhq#6319, maximhq#6299, maximhq#6327, maximhq#6432, maximhq#6351)
- **Documentation** - v2.0.0 migration guide with the governance

deployments, v2.0.0 availability callouts, routing API namespace docs,
Bedrock application inference profiles, Splunk connector docs,
config.schema.json and Datadog env var reference fixes, and Discord
badge fixes (thanks [@Swpn0neel](https://github.com/Swpn0neel)!) (maximhq#6332,
maximhq#6374, maximhq#6420, maximhq#6147, maximhq#6203, maximhq#6099, maximhq#5938, maximhq#6019, maximhq#6425, maximhq#6448)

## 🗄️ Database Migrations

All migrations below are new relative to v1.6.11. Deployments on an
older v1.6.x release should also review the intermediate v1.6.x
changelogs.

**configstore:**

- **add_mcp_client_pending_oauth_config_json_column** - Adds
`pending_oauth_config_json` to `config_mcp_clients`. Reversible: drops
the added column.
- **merge_oauth_token_tables** - Consolidates `oauth_tokens` and
`oauth_user_tokens` into `mcp_oauth_tokens`. **Non-reversible**:
rollback deliberately leaves `mcp_oauth_tokens` in place, because every
OAuth read and write targets it from this migration onward and dropping
it would destroy any token created or refreshed since, forcing every
holder to re-authorize.
- **create_mcp_oauth_flows_table** - Creates `mcp_oauth_flows` to track
in-flight OAuth flows. Reversible: drops the new table.
- **drop_oauth_config_pkce_columns** - Drops CSRF state, PKCE verifier
and `expires_at` from the OAuth config table now that they live on
`mcp_oauth_flows`. **Non-reversible**: forward-only, the dropped values
were per-flow ephemeral and re-adding empty columns would restore
nothing.
- **drop_oauth_config_token_id_column** - Drops `token_id`.
**Non-reversible**: forward-only, it was a pure FK shortcut now
reachable via `(oauth_config_id, auth_mode)`.
- **add_mcp_admin_auth_mode_indexes** - Adds admin partial unique
indexes on `mcp_oauth_tokens` and `mcp_per_user_header_credentials`.
Reversible: drops both indexes.
- **add_mcp_client_token_exchange_json_column** - Adds
`token_exchange_json` to `config_mcp_clients`. Reversible: drops the
added column.
- **add_needs_session_stickiness_column** - Adds
`needs_session_stickiness` to `config_mcp_clients`. Reversible: drops
the added column.
- **add_bedrock_endpoints_columns** - Adds Bedrock VPC endpoint columns
to the keys table. Reversible: drops the added columns.
- **add_cost_per_request_pricing_column** - Adds `cost_per_request` to
model pricing. Reversible: drops the added column.
- **add_notifications_table** - Creates the `notifications` table for
the dashboard notification center. Reversible: drops the table.
- **add_batch_jobs_table** - Creates `batch_jobs` with a unique
`(provider, batch_id)` identity index, a sweeper scan index and a
runner-id index. Reversible: drops the table.
- **add_image_megapixel_tier_pricing_columns** - Adds the five
`output_cost_per_image_above_{4,8,16,32,64}_megapixels` columns to model
pricing. Reversible: drops the added columns.
- **add_input_cost_per_query_column** - Adds `input_cost_per_query` to
model pricing for rerank. Reversible: drops the added column.
- **add_ultrafast_pricing_columns** - Adds the four `*_ultrafast` token
rate columns to model pricing. Reversible: drops the added columns.
- **add_image_size_quality_pricing_columns** - Adds the 14 per-size and
size+quality image output rate columns to model pricing. Reversible:
drops the added columns.
- **add_batch_jobs_attribution_columns** - Adds `user_id`, `team_id`,
`customer_id` and `source_log_id` to `batch_jobs` plus a `user_id`
index. Reversible: drops the index and the four columns.

**logstore:**

- **logs_add_guardrail_debug_column** - Adds `guardrail_debug` to logs.
Reversible: drops the added column.
- **mcp_tool_logs_add_redaction_mapping_column** - Adds the redaction
mapping column to MCP tool logs. **Non-reversible**: rollback is a no-op
because dropping the column would permanently destroy reveal data for
already-redacted MCP logs.
- **logs_add_user_agent_column** - Adds user agent and app columns,
their indexes, and a `UserAgentMapping` table. Reversible: drops the
indexes and the mapping table.
- **mcp_tool_logs_add_user_agent_column** - Adds user agent and app
columns plus indexes to MCP tool logs. Reversible: drops both indexes
and the `app` column.
- **logs_recreate_matviews_with_app_column** - Recreates the log
materialized views to include the user agent and app columns. Rollback
is a no-op because `ensureMatViews` recreates them on next startup.
- **mcp_tool_logs_add_endpoint_columns** - Adds `source`, `decision`,
`app_key` and `device_id` to MCP tool logs. Reversible: drops all four
columns.
- **mcp_tool_logs_add_plugin_logs_column** - Adds `plugin_logs` to MCP
tool logs. Reversible: drops the added column.
- **logs_add_video_edit_input_column** - Adds `video_edit_input` to
logs. Reversible: drops the added column.
- **logs_add_upstream_and_overhead_latency_columns** - Adds
`upstream_latency` and `overhead_latency` to logs. Reversible: drops
both columns.
- **logs_add_batch_debug_column** - Adds `batch_debug` to logs.
Reversible: drops the added column.
- **logs_add_cost_breakdown_columns** - Adds `input_cost`, `output_cost`
and `additional_cost` to logs. Reversible: drops the three columns.
- **logs_recreate_matviews_with_cost_breakdown** - Marks the hourly
matview for rebuild with the cost split columns; `repairMatViewShapes`
drops and recreates `mv_logs_hourly` on the next startup. Rollback is a
no-op because `ensureMatViews` recreates it on next startup.
- **logs_add_overhead_breakdown_column** - Adds `overhead_breakdown` to
logs. Reversible: drops the added column.

<Warning>
**High-throughput deployments: run the logstore migrations during a
low-activity window.**

Every logstore migration above alters `logs` or `mcp_tool_logs`, the two
highest-insert tables in Bifrost, and several also build indexes on
them. On a busy instance the index builds hold locks that block
concurrent log inserts for the duration of the build, and the matview
recreations rebuild against the full table. Schedule the upgrade for a
low-traffic period, or expect elevated log-write latency and possible
request-path backpressure while the migrations run.
</Warning>

<Warning>
`merge_oauth_token_tables`, `drop_oauth_config_pkce_columns` and
`drop_oauth_config_token_id_column` transform or remove existing OAuth
state and cannot be rolled back. Take a database backup before
upgrading, and do not roll the binary back past this release once the
migration has run.
</Warning>

…lls when resolved by sweeper (maximhq#6474)

## Summary

Surfaces batch accounting data (model, token usage, and cost) in the logs table UI, and ensures `batch_debug` is included in list queries so that data is available for display. Batch log entries that lack a top-level model, token usage, or cost now fall back to values derived from the batch debug accounting breakdowns. Additionally, the server version is propagated into the context at bootstrap so that batch accounting settlement logs carry a `UserAgent` field.

## Changes

- Added `BifrostContextKeyRuntimeVersion` context key and set it at server bootstrap so the runtime version is available throughout the request lifecycle.
- Added `userAgentFromContext` helper that reads the runtime version from context and builds a `"bifrost/<version>"` user agent string, falling back to `"bifrost"`.
- Passed the resolved user agent into `buildAggregateLog` and set it as `UserAgent` on the resulting log entry during batch accounting settlement.
- Added `batch_debug` to the `listSelectColumns` query so batch debug data is returned when listing log entries.
- Added a `batchAccountingDisplay` helper that aggregates model and token usage across `batch_debug.accounting.model_breakdowns`, returning `"mixed"` when multiple models are present.
- Model and token usage columns now fall back to `batchAccountingDisplay` when the top-level fields are absent.
- The cost column now renders the settled batch cost (from `batch_debug.accounting.cost`) with a tooltip explaining it is billed once, rather than showing `N/A`.
- Replaced `batchDebug`-gated UI logic with an `isBatch` flag derived from the log object type, so batch cancel and list operations are handled correctly even when `batch_debug` is absent.
- Batch ID and status in the detail view now fall back to the raw provider response payload when `batch_debug` is not present.
- Moved the status badge from the summary header section into the Details tab alongside the batch ID, so it is consistently sourced from either `batch_debug` or the raw response.

## Type of change

- [ ] Bug fix
- [x] Feature
- [ ] Refactor
- [ ] Documentation
- [ ] Chore/CI

## Affected areas

- [x] Core (Go)
- [x] Transports (HTTP)
- [ ] Providers/Integrations
- [ ] Plugins
- [x] UI (React)
- [ ] Docs

## How to test

1. Submit a batch request and wait for it to settle.
2. Open the logs table and locate the batch log entry.
3. Verify the model column shows the correct model name (or `"mixed"` for multi-model batches).
4. Verify the token usage column shows aggregated prompt, completion, and total tokens.
5. Verify the cost column shows the settled batch cost with a tooltip reading "Settled cost of this batch, billed once." instead of `N/A`.
6. Open a batch cancel or batch list log entry and verify the Details tab and batch ID/status fields render correctly without `batch_debug`.

```sh
# Core/Transports
go test ./...

# UI
cd ui
pnpm i || npm i
pnpm build || npm run build
```

## Screenshots/Recordings

Before: Model, token usage, and cost columns showed `N/A` for settled batch log entries. Batch cancel and list log entries did not render a Details tab or batch status.

After: All three columns display values derived from `batch_debug` accounting data, with a tooltip on the cost cell. Batch cancel and list entries correctly show or hide the Details tab based on object type.

<Note>
v2.0.0 is the first stable release on the 2.0 line. This changelog rolls
up `2.0.0-prerelease1` (based on
[v1.6.3](https://docs.getbifrost.ai/changelogs/v1.6.3)),
`2.0.0-prerelease2`, `2.0.0-prerelease3` and the final release window,
so it is the complete delta for a deployment upgrading from any v1.6.x
release. Fixes that also shipped on the v1.6.x line after v1.6.3 are
listed once here.
</Note>

<Warning>
**Breaking changes.** Read the [v2.0.0 migration
guide](https://docs.getbifrost.ai/migration-guides/v2.0.0) before
upgrading.

- **Custom plugin downloads are SSRF-protected** - a plugin `path`
pointing at an http(s) URL is rejected if it resolves to a loopback,
private, CGNAT, link-local or otherwise non-public address, and every
custom plugin path is re-verified on each restart, including ones
defined in `config.json`.
- **Custom plugin create and update require admin authentication** -
`POST /api/plugins` and `PUT /api/plugins/{name}` reject a custom `path`
when the caller only got through because dashboard auth is disabled or
unconfigured.
- **Governance APIs moved under `/api/governance/*`** - `/api/teams`,
`/api/users`, `/api/roles`, `/api/audit-logs` and other top-level
governance paths moved under one namespace; Team and User lists use
`limit`/`offset` pagination. Routing rules and the complexity analyzer
moved from `/api/governance/*` to `/api/routing/rules` and
`/api/routing/complexity-analyzer-config`; the old paths remain as
deprecated aliases.
- **`HTTPTransportPreHook` now runs after authentication** - the
pipeline is `HTTPTransportPreAuthHook -> auth -> HTTPTransportPreHook ->
handler`. Plugins that inject a credential (`x-bf-vk`, `Authorization`,
`x-api-key`) must move that work to the new `HTTPTransportPreAuthHook`,
and Go plugins implementing `HTTPTransportPlugin` must add the method
(`.so` plugins that predate it are skipped for that phase).
- **Legacy telemetry attributes removed** - the `gen_ai.*`-namespaced
Bifrost-internal span attributes,
`gen_ai.usage.prompt_tokens`/`completion_tokens`, the nanosecond
`time_to_first_token` attribute and `x-bf-prom-*` request-header
Prometheus dimensions are gone from the OTel and Prometheus connectors.
Dashboards should read the `bifrost.*` keys and `time_to_first_chunk`.
- **Gemini tool preference** - a Gemini API request carrying both
function declarations and Google Search without
`include_server_side_tool_invocations` now keeps the function
declarations and drops Google Search (previously the opposite). Set
`include_server_side_tool_invocations: true` to send both on Gemini 3
models. Vertex is unaffected.
</Warning>

## ✨ Features

- **Batch Accounting** - Provider batch jobs are tracked in a new
`batch_jobs` table and settled asynchronously: results are priced per
model from catalog batch rates (0.5 default ratio) on the `/results`
path, one aggregate cost log is written idempotently with the creating
request's identity, a background sweeper with ownership fencing
re-drives jobs that timed out, settled usage is charged exactly once to
the creating user's budgets and rate limits (including unscoped virtual
key budgets on model-less batch-create requests), mixed-model batch rows
are repriced during cost recalculation, and the log detail view shows a
Batch Details block with per-state request counts and the settled cost
(maximhq#5291, maximhq#5292, maximhq#5293, maximhq#5294, maximhq#5295, maximhq#5296, maximhq#6109, maximhq#6121, maximhq#6376, maximhq#6410,
maximhq#6474, maximhq#6505)
- **Claude-on-Vertex Batches** - Vertex batch jobs route Anthropic
models to `publishers/anthropic/...`, build Claude-on-Vertex JSONL
instances, round-trip `custom_id`, and preserve `tools`, `toolConfig`,
`cachedContent`, `labels` and `display_name` on Gemini/Vertex batch
requests (maximhq#5368)
- **Input / Output Cost Split** - Every log carries `input_cost`,
`output_cost` and `additional_cost` (guardrails, semantic cache, MCP)
next to the total, across the RDB, ClickHouse, matviews, recalculation
and the quota API; speech, transcription and OCR usages carry
`BifrostCost`; the log detail view shows the split with per-category
detail (maximhq#6511)
- **Bifrost Overhead Latency** - `upstream_latency` and
`overhead_latency` are recorded on every log, aggregated (avg, p90, p95,
p99) in the dashboard's new Bifrost Overhead chart and shown in the log
detail view; the overhead is decomposed by span self-time into
serialization, conversion, plugins, middleware, key selection, queue
wait, networking, client delivery and scheduling buckets (including
streaming per-chunk parse, conversion and backpressure and the worker
hand-off), persisted to `overhead_breakdown` and rendered as a stacked
bar in the log detail view; a `bifrost_overhead_latency_microseconds`
histogram is exported to Prometheus and OpenTelemetry and
`upstream_latency_ms`/`overhead_latency_ms` tags to Maxim, while
breakdown spans are kept out of observability connectors (maximhq#5533, maximhq#5534,
maximhq#5535, maximhq#6345, maximhq#6388, maximhq#6389, maximhq#6433, maximhq#6470, maximhq#6495)
- **Notification Center** - Role-targeted dashboard notifications stored
in the database, delivered over WebSocket and surfaced in a topbar tray
via `GET/POST /api/notifications` (maximhq#6207, maximhq#6227, maximhq#6324)
- **Topbar and Responsive Dashboard** - Persistent topbar with page
titles, theme toggle, external links, user menu and version; responsive
layouts across all views with truncation and tooltips for long values
and icon-only buttons; version-skew detection with an auto-reloading
upgrading screen (maximhq#6196, maximhq#6105, maximhq#6126, maximhq#6204, maximhq#6232, maximhq#6330, maximhq#6370,
maximhq#6476, maximhq#6485, maximhq#6493)
- **Video Edits** - `POST /v1/videos/edits` applies prompt-driven edits,
upscaling and background removal to an existing video supplied as bytes,
a URL or a provider video ID, on OpenAI and Runware (maximhq#6270)
- **Runware Chat, Catalog and Media Operations** - Chat completions,
streaming and Responses via Runware's OpenAI-compatible endpoint,
`ListModels` from the curated catalog, image upscale via
`/v1/images/edits` (`type=upscale`), image-to-3D and async 3D generation
via `/v1/videos` (`type=3d`), provider-reported per-task cost, and a raw
`/runware_passthrough` route (maximhq#6260, maximhq#6372, maximhq#6208, maximhq#6075)
- **JSON Image Edits** - `POST /v1/images/edits` accepts JSON bodies
with URL or base64 images and typed extra params in addition to
multipart (maximhq#6418)
- **OpenAI Ultrafast Service Tier** - `service_tier: "ultrafast"` is
forwarded only to models that support it and billed at dedicated
ultrafast rates, with matching custom pricing override fields (maximhq#6396,
maximhq#6399)
- **Service Tier on Logs** - Logs record the tier actually served,
including Anthropic's `service_tier` from `message_start` on streams,
with a Service Tier column and detail field so repricing uses the served
tier (maximhq#6233, maximhq#6236)
- **Pricing Fields** - New per-request flat fee (`cost_per_request`),
megapixel-based image tiers (4/8/16/32/64 MP), per-size and joint
size+quality image rates for `gpt-image-1`-style models, and
`input_cost_per_query` for rerank flow through datasheet sync, the cost
engine, custom overrides, the API and the UI override form; upscale
output resolution is backfilled from `target`/`factor` on Replicate so
tiered rates bill the real output size (maximhq#6079, maximhq#6082, maximhq#6083, maximhq#6379,
maximhq#6380)
- **Model Catalog Pricing and Overrides** - Pricing data in the model
catalog (thanks [@johnbrett](https://github.com/johnbrett)!), with
resolved pricing overrides exposed on `/api/models/details` and on
catalog rows, shown in the dashboard (maximhq#6055, maximhq#6056, maximhq#6058)
- **Typed Embeddings on Bedrock** - Titan V2 `embeddingTypes` and Cohere
`embedding_types` on Converse, the native invoke route and LangChain
`BedrockEmbeddings` (maximhq#6381)
- **Rerank Upgrades** - Structured JSON documents, `return_documents`,
`next_token` pagination, caller document IDs preserved in every result,
Cohere-shaped errors, cross-provider responses converted back to the
caller's wire shape, and `/genai/v1/rank` served cross-provider (maximhq#6328,
maximhq#6301, maximhq#6432)
- **OpenRouter Speech, Transcription and Embeddings** - TTS and STT
through OpenRouter's audio endpoints, and embedding models included in
`ListModels` (maximhq#5734, maximhq#6264)
- **Grok on Bedrock Mantle** - `xai.` models route through the
`openai/v1` Mantle path (maximhq#6022)
- **Gemini 3 Thinking Levels** - A per-model `thinkingLevel` support
table clamps requested levels to the rungs each model implements;
`reasoning_effort: "none"` sets the model's floor level instead of
zeroing `thinkingBudget` (maximhq#6280)
- **Datasheet-Backed Compatibility** - Anthropic, Bedrock, Cohere and
Gemini request shaping (adaptive thinking, native effort,
disable-reasoning, mid-conversation system turns, computer-use and
text-editor tool generations, default max output tokens, tool
validation) is resolved from model capabilities instead of hardcoded
model-name checks (maximhq#6281, maximhq#6492)
- **Reasoning Effort None** - Models that reason by default but do not
support reasoning with tool calls get `reasoning.effort: "none"` when
they advertise `supports_none_reasoning_effort`, instead of losing
`reasoning` entirely (maximhq#6293)
- **HTTP Transport Pre-Auth Hook** - New `HTTPTransportPreAuthHook`
plugin phase runs before transport authentication so plugins can inject
credentials such as `x-bf-vk`; a `virtual-key-from-config` native plugin
example ships alongside it (maximhq#6375, maximhq#6373)
- **Plugin Inject Limits** - Per-plugin `semaphore_size` and
`inject_timeout` on `PluginConfig` bound observability `Inject` calls so
a hung connector releases its slot (maximhq#6341)
- **Harness Session Autodetection** - Claude Code, Codex CLI and
OpenCode session headers populate the session ID when `x-bf-session-id`
is absent (maximhq#6333)
- **Auth and Model Check Skip Paths** - Context keys let trusted
internal callers bypass auth resolution, and let evaluate-only requests
such as `/inspect` bypass the virtual key provider and model allowlists
while budgets and rate limits still apply (maximhq#6124, maximhq#6479)
- **Passthrough Encoding Negotiation** - Forwarded `Accept-Encoding` is
filtered to decodable codecs (gzip, deflate, brotli, zstd; gzip and
identity for streams) and chained content encodings are decoded (maximhq#6360)
- **Routing Plugin** - Routing rules and the complexity router live in a
dedicated `routing` plugin that runs after governance so rules evaluate
on the fully stamped context; endpoints moved to `/api/routing/rules`
and `/api/routing/complexity-analyzer-config` with deprecated
`/api/governance/*` aliases; complexity routing now reads the text of
mixed text+image turns (maximhq#6144, maximhq#6145, maximhq#6146, maximhq#6147, maximhq#6253)
- **Dimension Scope Ceiling** - Grouped log analytics (rankings,
histograms, key pairs) are bounded to the customer, team, business unit,
user and virtual key ids the caller may see (maximhq#6262)
- **MCP Per-User OAuth and Token Exchange** - MCP clients can hold
per-user OAuth credentials and per-user headers, configurable from
`config.json` as well as the UI, with a documented shared vs
per-identity token lookup contract, `oauth_config.resource` (RFC 8707),
VK/Users filters on the OAuth Grants and MCP Auth Sessions sidebars and
one shared create/install client form; `token_exchange` gains
`use_idp_credentials` to reuse SSO login app credentials for providers
such as Microsoft Entra ID (`client_id` becomes optional) and combines
`offline_access` with `<audience>/.default` for Entra OBO; shared-OAuth
clients show `needs_reauth` when their token row is invalidated,
`Reauthorize` is limited to shared clients, the OAuth flow claim is
atomic against concurrent reauth, stored scopes survive a decode
failure, and credential caches propagate cancellation and version their
entries (maximhq#6068, maximhq#6069, maximhq#6078, maximhq#6411, maximhq#6428, maximhq#6429, maximhq#6504)
- **MCP Connection Lifecycle and Tool Discovery** - Discovered tools
persist and resync uniformly across all client types through a
hash-gated core callback, surviving restarts and propagating across a
cluster; connections use make-before-break reconnects with ephemeral
clients rebuilt across the whole connect+init retry, last-known tool
maps preserved, connect attempts bound to entry identity and background
reconnects deduped; `needs_session_stickiness` is pinned across
`config.json` reconciliation; updating static headers on a sticky client
pre-flight verifies the new credential and swaps it onto the live
connection, per-call shared-credential clients refresh tools
synchronously, and a failed enable parks the client at `Disabled` so it
can be retried; the global `tool_sync_interval` hot-reloads and re-times
running checkers; state badges render with spaces and the `disconnected`
filter bucket is now `unstable` (maximhq#6409, maximhq#6430, maximhq#6431, maximhq#6483, maximhq#6502)
- **Air-Gapped MCP Catalog** - `mcp_library_sync_interval: 0` disables
catalog sync and `file://` URLs load the MCP server library from disk
(maximhq#6195)
- **MCP Log Redaction and Plugin Logs** - MCP tool logs carry redaction
mappings and plugin logs (maximhq#5744, maximhq#5746)
- **Splunk Connector Configuration** - `config.schema.json`, Helm values
and dashboard entries for the Splunk HEC observability connector (maximhq#6296,
maximhq#6091, maximhq#6099)
- **Helm Broker Clustering** - `bifrost.cluster.type: broker` with
broker address, port and TLS settings alongside the existing mesh
transport (maximhq#6398)
- **HTTP/2 Ping Interval in the UI** - Provider network configuration
exposes `http2_ping_interval_in_seconds` (maximhq#6228)
- **Status Code Badges** - Error and passthrough logs show the upstream
HTTP status code in the log detail header (maximhq#5536)
- **Server-Side Tool Calls in Logs** - `web_search_call`,
`code_interpreter_call` and similar Responses items render their full
payload in the log detail view (maximhq#6475)
- **Gemini Server-Side Tool Calls** - Gemini `toolCall`/`toolResponse`
parts surface as `web_search_call` items with their own call ID and
queries, unmapped tool types are preserved on the native round-trip, and
each `thoughtSignature` appears exactly once on replay (maximhq#6071)
- **Bedrock VPC Endpoints** - AWS Bedrock keys can target VPC endpoints
(maximhq#6064)
- **W3C Trace ID Propagation** - Requests carry a W3C trace ID on the
context (maximhq#5945)
- **Durable Background Jobs** - New `sidekiq` background-job table,
store methods, and runner with recovery and reaper; cost recalculation
migrated to a durable, resumable and cancellable job with polling
instead of SSE (maximhq#5800, maximhq#5801)
- **Separate OTEL Metrics Pipeline** - The OTEL collector supports a
metrics tab independent of traces, plus separate headers for traces and
metrics (maximhq#5939, maximhq#5940)
- **Grouped Logs View** - The logs table groups fallback chains under
expandable roots backed by the new `roots_only` filter with child
aggregates, and the model catalog persists tab, search and provider in
the URL (maximhq#5522, maximhq#5737, maximhq#6059)
- **User Agent and App Attribution** - Logs and MCP tool logs record
user agent, app, source, decision, app key and device ID, with custom
user-agent mapping and dashboard dimension rankings; MCP tool logs
observed by the Bifrost Edge agent can be ingested with device, app key,
decision and source attribution
- **S3 Log Export Metadata** - Additional metadata is written alongside
S3 log exports (maximhq#6070)
- **Matview Maintenance Off Switch** - `matview_refresh_interval`
accepts `"off"` to disable logstore matview maintenance entirely (thanks
[@jeremym-tanium](https://github.com/jeremym-tanium)!) (maximhq#5693)
- **Video Request Info in Logs UI** - Video requests surface their
details in the logs UI (maximhq#5946)
- **Shell Rewriter Hook** - The UI handler exposes a `ShellRewriter`
hook for pre-hydration HTML rewriting (maximhq#5807)
- **Custom Branding** - Logo and icon branding support with an OSS
fallback stub, cached in localStorage to prevent a logo flash on load
(maximhq#5806, maximhq#6096)
- **User Assignment on Virtual Keys** - Users can be assigned from the
virtual key sheet (maximhq#5863)
- **Quarterly Budgets** - Quarterly budget windows with a configurable
fiscal year start for customers and virtual key provider configs,
surfaced in budget labels (maximhq#5996, maximhq#5997, maximhq#5999, maximhq#6115, maximhq#6116)
- **Sarvam AI Provider** - Added Sarvam AI as a first-class provider
with chat, text-to-speech, and speech-to-text support (thanks
[@Purvi09](https://github.com/Purvi09)!)
- **ElevenLabs Sound Effects** - Added text-to-sound generation support
via `/v1/sound-generation` (thanks
[@SecretSun](https://github.com/SecretSun)!)
- **Bedrock Project Scoping** - Added optional `project_id` to Bedrock
and Bedrock Mantle key configs with per-alias overrides for Bedrock,
Bedrock Mantle, and Vertex, plus UI support
- **Trace Redaction** - Phase-scoped redaction and revealing, transient
redaction data field for guardrails, and trace content redaction before
connector export
- **Audit Log Object Storage** - S3/GCS object storage config schema for
audit log archival
- **Alerting Configuration** - Alerting schema in `config.schema.json`
with declarative channels and CEL-based rules, Helm chart support, and
enterprise fallback pages
- **Canonical Model Names** - Dashboard model rankings now show
canonical model names instead of inference-profile IDs (thanks
[@satyamkrishna](https://github.com/satyamkrishna)!)
- **OAuth2 Hardening** - Allowlist for private-use redirect URI schemes
(RFC 8252 §7.1) and a `shouldSweep` gate on the OAuth2 sweep worker
- **Mirrored Schema Support** - `schema_url` / `BIFROST_SCHEMA_URL` for
mirrored schema locations in isolated deployments
- **Vertex Single-Region Config** - Enforce single-region configuration
in Vertex key config
- **Helm Chart Updates** - `bifrost.alerting`, audit-log object storage,
`postgresql.external.port` string support, and
`bifrost.mcp.toolGroups[*].id`
- **ChatGPT Passthrough** - Added a ChatGPT passthrough route on the
OpenAI integration with dedicated request handling
- **Edge Fallback Pages** - Added fallback pages for Bifrost Edge
control views (config, devices, inventory) backed by governance resolver
support
- **Agent Handover View** - Added an agent handover page with seeded
end-to-end data support
- **First-Time Setup Token** - A setup token gates first-time setup so a
fresh deployment is not open to the world, and the onboarding checklist
is back, completing its dashboard auth step on SSO deployments (maximhq#5759,
maximhq#5784, maximhq#6322)

## 🐞 Fixed

- **Structured Output Schema Order** - `response_format` JSON schemas
are forwarded byte-for-byte to OpenAI, Anthropic, Bedrock, Gemini and
Cohere so the model generates fields in the caller's declared order
instead of a re-sorted one (maximhq#6235)
- **Thinking Block Typing on Streams** - Reasoning items carrying both
an encrypted payload and a visible summary open as `thinking` blocks
instead of `redacted_thinking` (maximhq#6292)
- **Replayed Thinking Blocks via `bedrock/` Prefix** - Content-less
`tool_result` blocks are kept, interleaved block order is preserved,
`incomplete` maps to `error` on Converse, and pending reasoning is
consumed by its owning item, so multi-turn tool use no longer wedges
(maximhq#6346)
- **Gemini 400s on Claude Code Traffic** - Trailing assistant prefills
are trimmed and mid-conversation system turns are inlined for
Gemini/Vertex; `extra_fields` is echoed on `/anthropic/v1/messages`
(maximhq#6363)
- **Bedrock Tool Use IDs** - IDs longer than 64 characters or outside
Bedrock's charset (such as Gemini thought-signature IDs) are aliased
deterministically on both `tool_use` and `tool_result` (maximhq#6300)
- **Azure Responses Stream Errors** - Terminal `error` and
`response.failed` events inside an already-open HTTP 200 SSE stream are
surfaced as errors with their nested type, code and message (thanks
[@dani29](https://github.com/dani29)!) (maximhq#6302)
- **GenAI SSE Heartbeats** - GenAI streams delimit heartbeat comments so
Google SDK clients preserve the following event, while older openai-go
clients keep the bare heartbeat (thanks
[@dani29](https://github.com/dani29)!) (maximhq#6252)
- **OpenCode max_tokens** - `max_tokens` is preserved for
OpenCode-compatible chat endpoints (thanks
[@Alex-wangyang](https://github.com/Alex-wangyang)!) (maximhq#6458)
- **HuggingFace Streaming Usage** - HuggingFace is no longer listed as
omitting the `[DONE]` marker, and `stream_options.include_usage`
defaults on its chat streaming path, so streamed calls stop reporting
zero tokens and zero cost (thanks
[@elliottrabac](https://github.com/elliottrabac)!) (maximhq#6478)
- **Provider Key Name on Update** - A key PUT that omits `name` no
longer clears it, and already-exists errors keep their constraint detail
(thanks [@cpsc](https://github.com/cpsc)!) (maximhq#6417)
- **Bedrock Mantle Streaming** - Bedrock Mantle is registered in
`ProviderSendsDoneMarker` so streams end after `finish_reason` (maximhq#6021)
- **URL-Sourced Files and Images** - `gs://` URIs go to Gemini/Gemma as
`fileData.fileUri` and are read from Cloud Storage for Claude-on-Vertex,
`s3://` references go to Bedrock Converse as `s3Location`, Bedrock
rerank synthesizes the foundation-model ARN from a bare model ID, OpenAI
file blocks keep `file_url`, non-http schemes pass through on the OpenAI
and native-Anthropic paths, and Gemini always emits a candidate with its
finish reason and drops payload-free parts (maximhq#6239)
- **Together and Alias Pricing** - The management catalog resolves
runtime provider `together` to the datasheet identity and prices
configured aliases through their target model (thanks
[@dani29](https://github.com/dani29)!) (maximhq#6257, maximhq#6320)
- **Redis Vector Store TAG Escaping** - All RediSearch special
characters are escaped in TAG query values (thanks
[@AdityaPainuli](https://github.com/AdityaPainuli)!) (maximhq#5351)
- **MCP Tool Sync Interval Corruption** - Toggling an MCP client's
enable/disable switch no longer corrupts `tool_sync_interval`; the value
is a whole number of minutes, negative values are rejected instead of
silently disabling sync, and re-enabling a per-call client restarts its
discovery cycle (maximhq#6409, maximhq#6502)
- **MCP Tool Map Staleness** - `SetClientTools` replaces the in-memory
tool map instead of merging, so tools removed upstream leave memory once
the database has dropped them (maximhq#6484)
- **SSE Reconnect Identity** - `OnConnectionLost` on SSE MCP clients is
gated on connection identity so a stale connection cannot tear down its
replacement
- **Connector Header Redaction** - `Authorization`, `x-api-key`,
Cloudflare Access and AWS ALB OIDC headers are redacted before export to
every observability backend (maximhq#6371)
- **Vertex Mixed Tools** - Vertex AI accepts function declarations and
Google Search in the same request without
`includeServerSideToolInvocations`, and search localization via
`retrievalConfig.latLng` is preserved (maximhq#6066)
- **Gemini Tool Preference** - When tool combination is disabled,
function declarations win over Google Search so the model can still call
the caller's tools (maximhq#6065)
- **Bedrock Stop Reasons** - Bedrock `content_filter` and
`guardrail_intervened` stop reasons map to `incomplete` status with a
`content_filter` reason

`tool_search` on the Responses path (thanks
[@ws4charlie](https://github.com/ws4charlie)!)

cached span pointers, reusable worker delivery timers, retained span
attribute maps, generation-stamped memoization of `GetProvidersForModel`
and `GetModelsForProvider` via the new `gencache` package, sonic-based
JSON responses, and a plugin-log existence check before draining (maximhq#6242,
maximhq#6241, maximhq#5956, maximhq#5957, maximhq#5657, maximhq#6387, maximhq#5641, maximhq#6224, maximhq#6268, maximhq#6211)
- **Go Toolchain** - Modules build with Go 1.26.6 and the Nix flake pins
1.26.7 (maximhq#6269, maximhq#6385)
- **Dependency Upgrades** - Dependabot updates across all modules,
newman 6.2.2 with pinned transitive overrides, module path fixes and
`openai_config` referenced from every provider config schema (maximhq#6040,
maximhq#5864, maximhq#6267, maximhq#6305, maximhq#6275)
- **Test Coverage** - vLLM instances provisioned on RunPod in the
release pipeline, Runware harness coverage including `/v1/images/edits`
and `/v1/videos`, batch and pricing-override lifecycle harness cases, an
Anthropic `message_start` usage regression test, LangChain rerank and
embedding integration tests, and e2e fixes for dashboard auth, budget
reset and MCP state (maximhq#5541, maximhq#6303, maximhq#6319, maximhq#6299, maximhq#6327, maximhq#6432, maximhq#6351)
- **Documentation** - v2.0.0 migration guide with the governance
namespace mapping and a v1.5.x downgrade guide for `prerelease3`
deployments, v2.0.0 availability callouts, routing API namespace docs,
Bedrock application inference profiles, Splunk connector docs,
config.schema.json and Datadog env var reference fixes, and Discord
badge fixes (thanks [@Swpn0neel](https://github.com/Swpn0neel)!) (maximhq#6332,
maximhq#6374, maximhq#6420, maximhq#6147, maximhq#6203, maximhq#6099, maximhq#5938, maximhq#6019, maximhq#6425, maximhq#6448)

families (maximhq#5839)

## 🗄️ Database Migrations

All migrations below are new relative to v1.6.11. Deployments on an
older v1.6.x release should also review the intermediate v1.6.x
changelogs.

**configstore:**

- **add_mcp_client_pending_oauth_config_json_column** - Adds
`pending_oauth_config_json` to `config_mcp_clients`. Reversible: drops
the added column.
- **merge_oauth_token_tables** - Consolidates `oauth_tokens` and
`oauth_user_tokens` into `mcp_oauth_tokens`. **Non-reversible**:
rollback deliberately leaves `mcp_oauth_tokens` in place, because every
OAuth read and write targets it from this migration onward and dropping
it would destroy any token created or refreshed since, forcing every
holder to re-authorize.
- **create_mcp_oauth_flows_table** - Creates `mcp_oauth_flows` to track
in-flight OAuth flows. Reversible: drops the new table.
- **drop_oauth_config_pkce_columns** - Drops CSRF state, PKCE verifier
and `expires_at` from the OAuth config table now that they live on
`mcp_oauth_flows`. **Non-reversible**: forward-only, the dropped values
were per-flow ephemeral and re-adding empty columns would restore
nothing.
- **drop_oauth_config_token_id_column** - Drops `token_id`.
**Non-reversible**: forward-only, it was a pure FK shortcut now
reachable via `(oauth_config_id, auth_mode)`.
- **add_mcp_admin_auth_mode_indexes** - Adds admin partial unique
indexes on `mcp_oauth_tokens` and `mcp_per_user_header_credentials`.
Reversible: drops both indexes.
- **add_mcp_client_token_exchange_json_column** - Adds
`token_exchange_json` to `config_mcp_clients`. Reversible: drops the
added column.
- **add_needs_session_stickiness_column** - Adds
`needs_session_stickiness` to `config_mcp_clients`. Reversible: drops
the added column.
- **add_bedrock_endpoints_columns** - Adds Bedrock VPC endpoint columns
to the keys table. Reversible: drops the added columns.
- **add_cost_per_request_pricing_column** - Adds `cost_per_request` to
model pricing. Reversible: drops the added column.
- **add_notifications_table** - Creates the `notifications` table for
the dashboard notification center. Reversible: drops the table.
- **add_batch_jobs_table** - Creates `batch_jobs` with a unique
`(provider, batch_id)` identity index, a sweeper scan index and a
runner-id index. Reversible: drops the table.
- **add_image_megapixel_tier_pricing_columns** - Adds the five
`output_cost_per_image_above_{4,8,16,32,64}_megapixels` columns to model
pricing. Reversible: drops the added columns.
- **add_input_cost_per_query_column** - Adds `input_cost_per_query` to
model pricing for rerank. Reversible: drops the added column.
- **add_ultrafast_pricing_columns** - Adds the four `*_ultrafast` token
rate columns to model pricing. Reversible: drops the added columns.
- **add_image_size_quality_pricing_columns** - Adds the 14 per-size and
size+quality image output rate columns to model pricing. Reversible:
drops the added columns.
- **add_batch_jobs_attribution_columns** - Adds `user_id`, `team_id`,
`customer_id` and `source_log_id` to `batch_jobs` plus a `user_id`
index. Reversible: drops the index and the four columns.

**logstore:**

- **logs_add_guardrail_debug_column** - Adds `guardrail_debug` to logs.
Reversible: drops the added column.
- **mcp_tool_logs_add_redaction_mapping_column** - Adds the redaction
mapping column to MCP tool logs. **Non-reversible**: rollback is a no-op
because dropping the column would permanently destroy reveal data for
already-redacted MCP logs.
- **logs_add_user_agent_column** - Adds user agent and app columns,
their indexes, and a `UserAgentMapping` table. Reversible: drops the
indexes and the mapping table.
- **mcp_tool_logs_add_user_agent_column** - Adds user agent and app
columns plus indexes to MCP tool logs. Reversible: drops both indexes
and the `app` column.
- **logs_recreate_matviews_with_app_column** - Recreates the log
materialized views to include the user agent and app columns. Rollback
is a no-op because `ensureMatViews` recreates them on next startup.
- **mcp_tool_logs_add_endpoint_columns** - Adds `source`, `decision`,
`app_key` and `device_id` to MCP tool logs. Reversible: drops all four
columns.
- **mcp_tool_logs_add_plugin_logs_column** - Adds `plugin_logs` to MCP
tool logs. Reversible: drops the added column.
- **logs_add_video_edit_input_column** - Adds `video_edit_input` to
logs. Reversible: drops the added column.
- **logs_add_upstream_and_overhead_latency_columns** - Adds
`upstream_latency` and `overhead_latency` to logs. Reversible: drops
both columns.
- **logs_add_batch_debug_column** - Adds `batch_debug` to logs.
Reversible: drops the added column.
- **logs_add_cost_breakdown_columns** - Adds `input_cost`, `output_cost`
and `additional_cost` to logs. Reversible: drops the three columns.
- **logs_recreate_matviews_with_cost_breakdown** - Marks the hourly
matview for rebuild with the cost split columns; `repairMatViewShapes`
drops and recreates `mv_logs_hourly` on the next startup. Rollback is a
no-op because `ensureMatViews` recreates it on next startup.
- **logs_add_overhead_breakdown_column** - Adds `overhead_breakdown` to
logs. Reversible: drops the added column.

<Warning>
**High-throughput deployments: run the logstore migrations during a
low-activity window.**

Every logstore migration above alters `logs` or `mcp_tool_logs`, the two
highest-insert tables in Bifrost, and several also build indexes on
them. On a busy instance the index builds hold locks that block
concurrent log inserts for the duration of the build, and the matview
recreations rebuild against the full table. Schedule the upgrade for a
low-traffic period, or expect elevated log-write latency and possible
request-path backpressure while the migrations run.
</Warning>

<Warning>
`merge_oauth_token_tables`, `drop_oauth_config_pkce_columns` and
`drop_oauth_config_token_id_column` transform or remove existing OAuth
state and cannot be rolled back. Take a database backup before
upgrading, and do not roll the binary back past this release once the
migration has run.
</Warning>
