Summary

This release includes several bug fixes and new features, primarily focusing on Anthropic beta headers support, provider reliability improvements, and enhanced model metadata capabilities.

Changes

Fixed timeout status code handling - Standardized timeout error responses across all providers
Enhanced semantic cache - Preserved cached provider metadata during cross-provider cache hits to maintain consistency
Prevented content leakage - Fixed issue where reasoning text was incorrectly appearing in Gemini response content
Added Anthropic beta headers support - Implemented validation and filtering of anthropic-beta headers for Azure, Bedrock, and Vertex AI providers with configurable overrides
Added model details API - New /api/models/details endpoint providing model capability metadata
Fixed governance APIs - Properly populated customer virtual_keys in governance API responses
Improved enterprise model catalog - Enhanced sync reliability for enterprise deployments

Type of change

How to test

Validate the changes with the following steps:

# Core/Transports
go version
go test ./...

# Test Anthropic beta headers
curl -X POST /v1/chat/completions \
  -H "anthropic-beta: computer-use-2024-10-22" \
  -H "Content-Type: application/json" \
  -d '{"model": "claude-3-sonnet", "messages": [{"role": "user", "content": "Hello"}]}'

# Test model details endpoint
curl /api/models/details

# Test timeout handling
# Configure a provider with very low timeout and verify proper error codes

The beta headers feature can be configured via the Beta Headers tab in provider configuration or through beta_header_overrides in provider settings.

Screenshots/Recordings

Added documentation screenshots showing the Beta Headers configuration interface for:

AWS Bedrock Anthropic beta headers configuration
Azure Anthropic beta headers configuration
Vertex AI Anthropic beta headers configuration

Breaking changes

Yes
No

Related issues

This release addresses provider reliability and adds support for Anthropic's beta feature ecosystem across cloud providers.

Security considerations

Beta headers are validated and filtered to prevent unsupported features from being forwarded
Timeout handling improvements reduce potential for hanging requests
Model metadata endpoint follows existing authentication patterns

Walkthrough

Release bump across core, framework, transports, and multiple plugins; added changelog entries and updated Anthropic beta header docs for Azure/Bedrock/Vertex. Migration test seed now includes calendar_aligned for governance budgets.

Changes

Cohort / File(s)	Summary
Core & Framework `core/version`, `core/changelog.md`, `framework/version`, `framework/changelog.md`	Core and framework version bumps (core 1.4.15→1.4.16, framework 1.2.34→1.2.35) and added changelog entries (timeout handling, cached metadata preservation, Gemini reasoning removal, models/details endpoint).
Transports `transports/version`, `transports/changelog.md`	Version bump (1.4.18→1.4.19) with detailed changelog covering Model Details API, Anthropic beta header support, multiple fixes, and maintenance notes.
Plugins — versions & changelogs `plugins/governance/version`, `plugins/governance/changelog.md`, `plugins/jsonparser/...`, `plugins/litellmcompat/...`, `plugins/logging/...`, `plugins/maxim/...`, `plugins/mocker/...`, `plugins/otel/...`, `plugins/semanticcache/...`, `plugins/telemetry/...`	Version increments across plugins (e.g., governance 1.4.34→1.4.35, jsonparser 1.4.33→1.4.34, litellmcompat 0.0.23→0.0.24, etc.) and small changelog entries (core/framework upgrade notes and targeted fixes).
Docs — Anthropic Beta Headers `docs/providers/supported-providers/azure.mdx`, `docs/providers/supported-providers/bedrock.mdx`, `docs/providers/supported-providers/vertex.mdx`	Documentation updated to state Bifrost validates and drops unsupported `anthropic-beta` headers (vs. prior behavior), plus embedded UI screenshots illustrating supported/unsupported features and overrides.
Migration Test Seed `.github/workflows/scripts/run-migration-tests.sh`	Added `calendar_aligned` column and values to `governance_budgets` SQL seed rows (explicit 0 and 1).

Poem

🐰 Hop, hop, hooray — the versions climb high,
Seeds sown for budgets beneath the sky,
Beta headers pruned with a careful paw,
Changelogs singing what code just saw,
A tiny rabbit cheers: release, oh my! 🥕

Confidence Score: 4/5

Safe to merge after fixing the boolean literal type mismatch in the migration test script.

One P1 defect: the new calendar_aligned INSERT values use integer literals 0/1 instead of false/true, which will cause the PostgreSQL migration test to error out. All other changes are version bumps, changelogs, and documentation which are straightforward and correct.

.github/workflows/scripts/run-migration-tests.sh — the calendar_aligned boolean values need to be changed from 0/1 to false/true.

Important Files Changed

Filename	Overview
.github/workflows/scripts/run-migration-tests.sh	Adds `calendar_aligned` column to the `governance_budgets` INSERT, but uses integer literals `0`/`1` instead of `false`/`true`, which will fail on PostgreSQL's native BOOLEAN type.
docs/providers/supported-providers/vertex.mdx	Updates behavior description from "unsupported headers are rejected with a clear error" to "drops unsupported headers from the request"; adds a screenshot frame. Documentation accurately reflects the new silently-dropping behavior.
docs/providers/supported-providers/bedrock.mdx	Updates beta-header behavior description to "drops unsupported headers" and adds screenshot frame; no issues found.
docs/providers/supported-providers/azure.mdx	Updates beta-header behavior description to "drops unsupported headers" and adds screenshot frame; no issues found.
transports/changelog.md	New changelog for transports v1.4.19, summarising all features and bug fixes in this release; no issues found.
core/changelog.md	New changelog entries for core v1.4.16 covering timeout, semantic cache, Gemini content-leak, and beta-headers fixes; no issues found.

Integer literals 0/1 incompatible with PostgreSQL BOOLEAN column

The calendar_aligned column is defined in Go as bool with gorm:"default:false", which GORM maps to a native BOOLEAN type in PostgreSQL. PostgreSQL does not accept bare integer literals (0, 1) for BOOLEAN columns and will throw ERROR: column "calendar_aligned" is of type boolean but expression is of type integer, causing the PostgreSQL migration test to fail.

Every other boolean column in this same script uses false/true (e.g. send_back_raw_request/send_back_raw_response in the config_providers insert, and enabled in config_log_store), both of which are valid boolean literals accepted by PostgreSQL and modern SQLite (≥ 3.23.0) alike.
