🛑 Breaking changes 🛑

• exporterhelper: remove deprecated exporterhelper.RetrySettings and exporterhelper.NewDefaultRetrySettings (#9256)
• configopaque: configopaque.String implements fmt.Stringer and fmt.GoStringer, outputting [REDACTED] when formatted with the %s, %q or %#v verbs(#9213) This may break applications that rely on the previous behavior of opaque strings withfmt.Sprintfto e.g. build URLs or headers. Explicitly cast the opaque string to a string before using it infmt.Sprintf` to restore the previous behavior.

🚀 New components 🚀

• extension/memory_limiter: Introduce a memory_limiter extension which receivers can use to reject incoming requests when collector doesn't have enough memory (#8632)
  The extension has the same configuration interface and behavior as the existing memory_limiter processor, which potentially can be deprecated and removed in the future

💡 Enhancements 💡

• configtls: add cipher_suites to configtls. (#8105)
  Users can specify a list of cipher suites to pick from. If left blank, a safe default list is used.

• service: mark telemetry.useOtelForInternalMetrics as stable (#816)

• exporters: Cleanup log messages for export failures (#9219)

  1. Ensure an error message is logged every time and only once when data is dropped/rejected due to export failure.
  2. Update the wording. Specifically, don't use "dropped" term when an error is reported back to the pipeline.
     Keep the "dropped" wording for failures happened after the enabled queue.
  3. Properly report any error reported by a queue. For example, a persistent storage error must be reported as a storage error, not as "queue overflow".

🧰 Bug fixes 🧰

• configgrpc: Update dependency to address a potential crash in the grpc instrumentation (#9296)
• otlpreceiver: Ensure OTLP receiver handles consume errors correctly (#4335)
  Make sure OTLP receiver returns correct status code and follows the receiver contract (gRPC)
• zpagesextension: Remove mention of rpcz page from zpages extension (#9328)

  The following methods/structs have been moved from obsreporttest to componenttest:

  • obsreporttest.TestTelemetry -> componenttest.TestTelemetry
  • obsreporttest.SetupTelemetry -> componenttest.SetupTelemetry
  • obsreporttest.CheckScraperMetrics -> TestTelemetry.CheckScraperMetrics
  • obserporttest.TestTelemetry.TelemetrySettings -> componenttest.TestTelemetry.TelemetrySettings()

• confignet: Deprecates DialContext and ListenContext functions. Use Dial and Listen instead. (#9258)
  Unlike the previous Dial and Listen functions, the new Dial and Listen functions take a context.Context like DialContext and ListenContext.
