    • Add image.distroless, alloy.resizePolicy and configReloader.resizePolicy values.

  Fixed

  • mimir.rules.kubernetes recovers after a restart while Mimir is unreachable. It no longer stays unhealthy until the next pod restart (grafana/alloy#7554).
• Nov 3, 2026 Security external-secrets v2.14.0

  Changed

  • Updating to the v2.14.0 version.

  Fixed

  • Make the upstream helm unit tests pass against our chart: expect our unprefixed resource names, the Giant Swarm image and metrics Services, drop the cases for upstream image, securityContext and CRD settings our templates do not use, and pin the chart version in the snapshot suites so release PRs do not break them.
• Nov 3, 2026 Connectivity envoy-gateway-app v1.10.5

  Changed

  • Update Envoy Gateway to v1.9.3.
  • Update Envoy Proxy image to distroless-v1.39.6, which includes CVE fixes and ca-certificates without the compromised eMudhra intermediate CAs.
  • Update architect to v10.16.4, which pushes the chart to the git catalogs with the architect GitHub App instead of the catalogbot account.

  Fixed

  • Fix the basic e2e suite for gateway-api-bundle v2, which deploys envoy-gateway as a Flux HelmRelease instead of an App CR.
  • The helm.sh/chart label is valid for long chart versions: the 63-character cut trims the whole trailing run of -, . and _.
• Nov 3, 2026 Developer Portal backstage v3.29.0

  Added

  • (gs) Add Gateways tab to the cluster detail page by @weatherhog — A cluster’s page has a Gateways tab: its Gateways with their listeners, and its HTTPRoutes with their parents and Accepted and ResolvedRefs conditions, failing routes first. Read from the installation’s metrics; clusters on an observability-bundle older than 3.6.0 show Not available.

  Fixed

  • (agent-platform) Refuse an answer to a request the task no longer asks by @QuentinBisson — When an agent’s question was already answered in Slack and the agent asked another, an answer sent from the session page is refused instead of being applied to the new question you never saw.

  Development and CI/CD

  • (ci) Run node-build’s tests on two containers by @fiunchinho — CircleCI’s node-build job splits the unit tests across two containers, cutting the job from 10 to 12 minutes to about 6 to 7, for about a fifth more credits.
