1.4.3 enterprise release notes

[akshaydeo]

Summary

Adds the Enterprise v1.4.3 changelog page and registers it in the docs navigation. This release is built on a clean OSS base of transports/v1.5.4 (fixing v1.4.2's pinned untagged commit) and delivers a large set of new capabilities and fixes across DAC, clustering, access/identity, guardrails, observability, and the dashboard.

Changes

• Added docs/changelogs/ent-v1.4.3.mdx documenting all features, fixes, and dependency versions for the Enterprise v1.4.3 release
• Registered changelogs/ent-v1.4.3 as the first entry in the Enterprise changelogs section of docs/docs.json

Key headline items covered in the changelog:

• Data Access Control (DAC) extended fleet-wide across API keys, access profiles, roles, guardrails, MCP clients/tool groups, customers, teams, business units, and OAuth tokens, with targeted per-entity cache hydration
• Broker-mode clustering routing inter-node traffic through a central gRPC relay for platforms without inbound peer connectivity (e.g. Cloud Run), plus heartbeat-based ghost node detection and cluster health APIs
• Temporary access tokens and MCP per-user OAuth for scoped, time-limited credentials
• Three new guardrail providers: CrowdStrike AIDR, Patronus AI, and Google Model Armor
• OTEL-parity attributes for Datadog and BigQuery exporters
• Dedicated Dashboard RBAC resource, role and access-profile duplication, calendar-aligned budgets at team/access-profile level, and cluster-gossiped feature flags

Confidence Score: 5/5

Documentation-only change adding release notes and a nav entry; no code logic is modified.

Both files are purely documentation. The changelog content is well-structured, the date matches the release, and the nav entry is correctly ordered before v1.4.2. No logic, migrations, or runtime behavior is affected.

No files require special attention.
