🛑 Breaking changes 🛑

• pkg/stanza: Move filelog.container.removeOriginalTimeField feature gate to beta (#33389)

  • Disable the filelog.container.removeOriginalTimeField feature gate to get the old behavior.

• resourcedetectionprocessor: Move processor.resourcedetection.hostCPUSteppingAsString feature gate to stable. (#31136)

• resourcedetectionprocessor: Remove processor.resourcedetection.hostCPUModelAndFamilyAsString feature gate. (#29025)

🚩 Deprecations 🚩

• hostmetricsreceiver: Set the receiver.hostmetrics.normalizeProcessCPUUtilization feature gate to stable. (#34763)

🚀 New components 🚀

• azurelogs_translater: Adds a new translater that converts Azure EventHub logs to OpenTelemetry logs used by the Azure Events Hub receiver. (#39704)
• dorisexporter: logs implementation (#33479)
• dorisexporter: traces implementation (#33479)

💡 Enhancements 💡

• otelarrowexporter: Allow separate arrow exporter per unique value of configured metadataKeys. (#34178)

• processor/transform: Add custom function to the transform processor to convert exponential histograms to explicit histograms. (#33827)

• datadogconnector: Map the new OTel semantic convention deployment.environment.name to env for OTLP traces in APM stats. (#35147)
  The old convention deployment.environment still works

• datadogexporter: Map the new OTel semantic convention deployment.environment.name to env for OTLP traces, metrics and logs. (#35147)
  The old convention deployment.environment still works

• file_storage: provide a new option to the user to create a directory on start (#34939)

• headersetterextension: adding default_value config (#34412)
  default_value config item applied in case context value is empty

• kafkaexporter: Add support for encoding extensions in the Kafka exporter. (#34384)
  This change adds support for encoding extensions in the Kafka exporter. Loading extensions takes precedence over the internally supported encodings.

• datadogexporter: Adds exporter.datadogexporter.metricremappingdisabled featuregate which disables renaming OpenTelemetry metrics to match Datadog semantics. This feature gate is only for internal use. (#35025)

• otelarrowexporter: Add BatcherConfig field following similar in OTLP exporter. (#34802)

• otelarrowreceiver: Add gRPC timeout propagation. (#34742)

• kafkareceiver: Add support for otlp_json encoding to Kafka receiver. The payload is deserialized into OpenTelemetry traces using JSON format. (#33627)
  This encoding allows the Kafka receiver to handle trace data in JSON format,
  enabling integration with systems that export traces as JSON-encoded data.

• pkg/ottl: Improved JSON unmarshaling performance by 10-20% by switching dependencies. (#35130)

• pkg/ottl: Added support for locale in the Time converter (#32978)

• remotetapprocessor: Origin header is no longer required for websocket connections (#34925)

• deltatorateprocessor: Remove unnecessary data copies. (#35165)

• transformprocessor: Remove unnecessary data copy when transform sum to/from gauge (#35177)

• sapmexporter: Prioritize token in context when accesstokenpassthrough is enabled (#35123)

• tailsamplingprocessor: Fix the behavior for numeric tag filters with inverse_match set to true. (#34296)

🧰 Bug fixes 🧰

• splunkenterprise: Fix a flaky search related to iops metrics. (#35081)

• azuremonitorexporter: fix issue for property endpoint is ignored when using instrumentation_key (#33971)

• groupbytraceprocessor: Ensure processor_groupbytrace_incomplete_releases metric has a unit. (#35221)

• datadogreceiver: Fix numeric span attributes (#35087)

• deltatocumulative: do not drop gauges and summaries (#35284)
  Gauges and Summaries are no longer dropped from processor output.
  Instead, they are passed through as-is

• pkg/stanza: Do not get formatted message for Windows events without an event provider. (#35135)
  Attempting to get the formatted message for Windows events without an event provider can result in an error being logged. |
  This change ensures that the formatted message is not retrieved for such events.

• cmd/opampsupervisor: Ensure the Supervisor processes all fields in a ServerToAgent message. (#34349)

• signalfxexporter: Ensure token is not sent through for event data (#35154)

• prometheusreceiver: Fix the retrieval of scrape configurations by also considering scrape config files (#34786)

• redactionprocessor: Fix panic when using the redaction processor in a logs pipeline (#35331)

• exporter/splunkhec: Fix incorrect claim that the exporter doesn't mutate data when batching is enabled. (#35306)
  The bug lead to runtime panics when the exporter was used with the batcher enabled in a fanout scenario.
