v1.13.0
Breaking risk
⚠ Upgrade required
- Add sablier.idle.replicas=1 to existing workloads that previously relied on CPU/memory throttling via idle.cpu or idle.memory settings.
Breaking changes
- sablier.idle.cpu and sablier.idle.memory no longer enable throttling without setting sablier.idle.replicas=1
Notable features
- --auto-stop-externally-started flag added
- OpenTelemetry distributed tracing support added
- SSE instance events endpoint (api) added
