v1.0.1/v0.92.0

🛑 Breaking changes 🛑

• exporters/sending_queue: Do not re-enqueue failed batches, rely on the retry_on_failure strategy instead. (#8382)
  The current re-enqueuing behavior is not obvious and cannot be configured. It takes place only for persistent queue
  and only if retry_on_failure::enabled=true even if retry_on_failure is a setting for a different backoff retry
  strategy. This change removes the re-enqueuing behavior. Consider increasing retry_on_failure::max_elapsed_time
  to reduce chances of data loss or set it to 0 to keep retrying until requests succeed.

• confmap: Make the option WithErrorUnused enabled by default when unmarshaling configuration (#7102)
  The option WithErrorUnused is now enabled by default, and a new option WithIgnoreUnused is introduced to ignore
  errors about unused fields.

• status: Deprecate ReportComponentStatus in favor of ReportStatus. This new function does not return an error. (#9148)

🚩 Deprecations 🚩

• connectortest: Deprecate connectortest.New[Metrics|Logs|Traces]Router in favour of connector.New[Metrics|Logs|Traces]Router (#9095)

• exporterhelper: Deprecate exporterhelper.RetrySettings in favor of configretry.BackOffConfig (#9091)

• extension/ballast: Deprecate memory_ballast extension. (#8343)
  Use GOMEMLIMIT environment variable instead.

• connector: Deprecate [Metrics|Logs|Traces]Router in favour of [Metrics|Logs|Traces]RouterAndConsumer (#9095)

💡 Enhancements 💡

• exporterhelper: Add RetrySettings validation function (#9089)
  Validate that time.Duration, multiplier values in configretry are non-negative, and randomization_factor is between 0 and 1

• service: Enable telemetry.useOtelForInternalMetrics by updating the flag to beta (#7454)
  The metrics generated should be consistent with the metrics generated
  previously with OpenCensus. Users can disable the behaviour
  by setting --feature-gates -telemetry.useOtelForInternalMetrics at
  collector start.

• mdatagen: move component from contrib to core (#9172)

• semconv: Generated Semantic conventions 1.22.0. (#8686)

• confignet: Add dialer_timeout config option. (#9066)

• processor/memory_limiter: Update config validation errors (#9059)

  • Fix names of the config fields that are validated in the error messages
  • Move the validation from start to the initialization phrase

• exporterhelper: Add config Validate for TimeoutSettings (#9104)

🧰 Bug fixes 🧰

• memorylimiterprocessor: Fixed leaking goroutines from memorylimiterprocessor (#9099)
• cmd/otelcorecol: Fix the code detecting if the collector is running as a service on Windows. (#7350)
  Removed the NO_WINDOWS_SERVICE environment variable given it is not needed anymore.
• otlpexporter: remove dependency of otlphttpreceiver on otlpexporter (#6454)

v0.91.0

💡 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)
