💡 Enhancements 💡

• statusreporting: Automates status reporting upon the completion of component.Start(). (#7682)
• service: add resource attributes as labels to otel metrics to ensures backwards compatibility with OpenCensus metrics. (#9029)
• semconv: Generated Semantic conventions 1.21. (#9056)
• config/confighttp: Exposes http/2 transport settings to enable health check and workaround golang http/2 issue golang/go#59690 (#9022)
• cmd/builder: running builder version on binaries installed with go install will output the version specified at the suffix. (#8770)

🧰 Bug fixes 🧰

• exporterhelper: fix missed metric aggregations (#9048)
  This ensures that context cancellation in the exporter doesn't interfere with metric aggregation. The OTel
  SDK currently returns if there's an error in the context used in Add. This means that if there's a
  cancelled context in an export, the metrics are now recorded.

• service: Fix bug where MutatesData would not correctly propagate through connectors. (#9053)

User facing changes

💡 Enhancements 💡

• fanoutconsumer: Enable runtime assertions to catch incorrect pdata mutations in the components claiming as non-mutating pdata. (#6794)
  This change enables the runtime assertions to catch unintentional pdata mutations in components that are claimed
  as non-mutating pdata. Without these assertions, runtime errors may still occur, but thrown by unrelated components,
  making it very difficult to troubleshoot.

🧰 Bug fixes 🧰

• exporterhelper: make enqueue failures available for otel metrics (#8673)
• exporterhelper: Fix nil pointer dereference when stopping persistent queue after a start encountered an error (#8718)
• cmd/builder: Fix ocb ignoring otelcol_version when set to v0.86.0 or later (#8692)

API changes

💡 Enhancements 💡

• pdata: Add IsReadOnly() method to p[metrics|logs|traces].[Metrics|Logs|Spans] pdata structs allowing to check if the struct is read-only. (#6794)

💡 Enhancements 💡

• service/telemetry exporter/exporterhelper: Enable sampling logging by default and apply it to all components. (#8134)
  The sampled logger configuration can be disabled easily by setting the service::telemetry::logs::sampling::enabled to false.
• core: Adds the ability for components to report status and for extensions to subscribe to status events by implementing an optional StatusWatcher interface. (#7682)

🧰 Bug fixes 🧰

• telemetry: remove workaround to ignore errors when an instrument includes a / (#8346)

API changes

💡 Enhancements 💡

• pdata: Introduce API to control pdata mutability (#6794)
  This change introduces new API pdata methods to control the mutability:
  • p[metric|trace|log].[Metrics|Traces|Logs].MarkReadOnly() - marks the pdata as read-only. Any subsequent
    mutations will result in a panic.
  • p[metric|trace|log].[Metrics|Traces|Logs].IsReadOnly() - returns true if the pdata is marked as read-only.
    Currently, all the data is kept mutable. This API will be used by fanout consumer in the following releases.
