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)

User facing changes

💡 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.

🛑 Breaking changes 🛑

• obsreport: remove methods/structs deprecated in previous release. (#8492)
• extension: remove deprecated Configs and Factories (#8631)
