💡 Enhancements 💡

  • cmd/mdatagen: Add support for defining stability levels for resource attributes (#15312)
  • cmd/mdatagen: Add semantic convention reference to resource attributes (#15313)
  • processor/memory_limiter: Adding health events for the memorylimiter (#14700) Publish health event from memorylimiter using componentstatus.ReportStatus

🧰 Bug fixes 🧰

  • cmd/mdatagen: Removes the extra line in the documentation.md between extended description and table (#15458)

  • exporter/otlp_http: Treat errors parsing successful (2xx) HTTP response bodies as permanent errors to prevent retrying already-accepted data. (#15386) When a server returns a 2xx status but the response body exceeds the 64kB read limit, the body is truncated and proto unmarshaling fails. Previously this was treated as a retryable error, causing duplicate data to be exported. Now it is marked as a permanent error so the retry logic will not re-send data that was already accepted by the server.

  • pkg/config/configretry: Always validate BackOffConfig fields regardless of the Enabled flag. (#15437)

  • pkg/service: Ensure receivers always start after all other components (#15495) There was previously a race condition where multiple receivers using a shared internal implementation, such as the OTLP receiver, could start sending telemetry into a pipeline before all its components had fully started.

  • processor/memory_limiter: Fix degenerate collector performance when exporter has problems causing permanent CPU-burning GC loop (#4981) Forced GC runs now use exponential backoff when deemed ineffective (still above soft limit and less than 5% reclaimed) to avoid preventing recovery by overloading CPU with excessive GC runs. The cap on the backoff interval is exposed via max_gc_interval_when_soft_limited and max_gc_interval_when_hard_limited (both default 30s); set either to 0 to disable backoff on that path.

  • provider/env: Fix empty env var default resolving to nil instead of empty string (#14587) When using ${env:VAR:-} with an unset variable, the empty default now correctly resolves to an empty string instead of nil.

🛑 Breaking changes 🛑

  • pkg/pprofile: add bounds checks to FromAttributeIndices (#15517)

💡 Enhancements 💡

  • cmd/mdatagen: Add field_name field to go_struct config in metadata.yaml to allow customizing the Go struct field name for generated config properties. (#15486)
  • cmd/mdatagen: Handle enum validators in generated config structs (#14805) Supported validators include enum.
  • cmd/mdatagen: Generate named Go types for primitive exported config schemas. (#15487) Primitive exported configs for string, integer, number, and boolean schemas now produce distinct exported types while default values and validation remain on referencing fields.
