  Full Changelog: https://github.com/giantswarm/muster/compare/v0.1.159...v0.1.160

• May 11, 2026 Developer Portal backstage v0.130.0

  Added

  • PagerDuty integration: “Who is on call” entity card, catalog processor that auto-annotates entities with PagerDuty IDs, and MCP action to resolve PagerDuty IDs from catalog entities.

  Changed

  • Backstage liveness/readiness probe timings are now configurable via .Values.probes.{liveness,readiness} (initialDelaySeconds, periodSeconds, timeoutSeconds, failureThreshold) and the default timeoutSeconds is raised from the k8s implicit 1 to 5. The HTTP path/port stay fixed (/.backstage/health/v1/{liveness,readiness} on port). The k8s default 1s is tight against the chart’s 500m CPU limit: event-loop stalls during plugin startup, GC, or DB reconnects regularly miss the deadline and surface as Unhealthy: ... context deadline exceeded events even though the pod keeps serving traffic (observed on the BWI Backstage Deployment on spidertron, 2026-05-11). See ./docs/releases/v0.130.0-changelog.md for more information.
