Changes and Releases

Updates on Giant Swarm workload cluster releases, apps, UI improvements and documentation changes.

• Jun 1, 2026 Security rbac-bootstrap-app v0.3.0

  Added

  • Add io.giantswarm.application.managed chart annotation for Backstage visibility.
  • Add optional cluster-reader ClusterRole (off by default, enabled via clusterReader.enabled: true) that aggregates into the built-in view ClusterRole and grants read access (get/list/watch) on cluster-scoped resources.

  Changed

  • Migrate chart metadata annotations to OCI-compatible format.
• Jun 1, 2026 Fleet Management kubectl-gs v5.6.4

  Added

  • login: new --oidc-scope flag (repeatable, comma-separated) appends extra scopes to the direct workload-cluster OIDC request. Use --oidc-scope=groups with Okta to receive group memberships in the ID token when the workload cluster’s structured auth is configured with groupsClaim.
• Jun 1, 2026 AI Agents klaus v0.0.177

  What’s Changed

  • chore(deps): update dependency @anthropic-ai/claude-code to v2.1.159 by @renovate[bot] in https://github.com/giantswarm/klaus/pull/286

  Full Changelog: https://github.com/giantswarm/klaus/compare/v0.0.176...v0.0.177

• Jun 1, 2026 Developer Portal backstage v0.133.0

  Added

  • AI chat: add Opus 4.8 context window info.

  Changed

  • AI chat: make the Anthropic thinking config model-aware so adaptive-thinking Claude models (Opus 4.5+, Sonnet 4.6) use the adaptive thinking interface with a configurable effort (aiChat.anthropic.effort, default high), while older Claude models keep the legacy budget-based interface.

  Fixed

  • AI chat: forward chat-level errors to the error reporter (Sentry) so the “Network error” banner is no longer silent, and log a backend warning when the client disconnects mid-stream. See ./docs/releases/v0.133.0-changelog.md for more information.
