Release notes

telemetry.otlpEndpoints — per-signal OTLP HTTP endpoints (logs, traces, metrics) that override the shared telemetry.otlpEndpoint. Also accepted under each per-service telemetryOverrides block (engine, experienceApi, coordinator). Empty pillars fall back to telemetry.otlpEndpoint, then to otelConfig.endpoint.
telemetry.resourceAttributes — global OTel resource attributes as a k=v,k=v string. Merged with per-service <service>.telemetryOverrides.resourceAttributes.

features.discovery_enabled (engine.yaml) — master switch for MCP tool discovery. Defaults to true. Set to false on on-prem deployments without Condex to skip the discovery skill, skip discovery-store allocation, and treat per-gateway discoveryEnabled flags as off.

Glean — enterprise search toolkit.
Cursor Cloud Agents — 16 tools for managing Cursor cloud agents.
Fly.io — application and machine management.
Gmail: local file attachments now also work in Claude Code and Codex CLI hosts (Cursor shipped in 1.8.7).
Google Sheets: multi-document access pre-flight (check access to many spreadsheets in one call), scan_for_data_issues deterministic bad-data flagger, and Drive comment-thread management tools.
Ashby: notes and feedback now surface their author names.

Tool-discovery state now persists across restarts so a restart no longer drops in-flight gateway discovery work.
OAuth Protected-Resource-Metadata documents are now cached so concurrent OAuth flows do not re-fetch the same upstream PRM.

SSO/OIDC users can create projects again — no longer rejects requests from the dashboard.
Outbound fetches inject the W3C traceparent header, restoring distributed-trace propagation across service boundaries.
Outbound HTTP calls propagate X-Request-Id end-to-end.
Content area no longer scrolls behind the sidebar — content is contained inside SidebarInset.
OAuth and gateway ID validation matches the backend slug rule, eliminating client/server-side mismatch.

New optional Helm values: telemetry.otlpEndpoints and telemetry.resourceAttributes. Existing single-endpoint setups continue to work; per-signal routing and resource-attribute layering are opt-in.
New optional engine config: features.discovery_enabled defaults to true. On-prem deployments without Condex should set it to false to skip discovery-store allocation entirely.
PRM document caching reuses the chart's existing Redis dependency — no additional infrastructure is required.
