End user changelog

🛑 Breaking changes 🛑

• elasticsearchexporter: Remove Index config, which was deprecated and replace with LogsIndex since v0.60.0 (#37094)

• elasticsearchexporter: Remove dedup config setting that was deprecated in v0.104.0 (#33773)

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

• pkg/ottl: Support dynamic indexing of maps and slices. (#36644)

• prometheusremotewriteexporter: Only append label values if they are different for colliding OTel attributes (#35896)
  This change ensures that, when translating colliding attributes from OTel attributes to Prometheus label, the label values are only appended if their values are different.
  This is a breaking change as it changes the value of label outputted.

• routingconnector: Disconnect match_once parameter from functionality. (#29882)
  The parameter will be ignored, except to trigger a warning log about its upcoming removal in v0.120.0.

🚩 Deprecations 🚩

• awscloudwatchmetricsreceiver: move the component to unmaintained status (#36599)
• githubgen: Deprecate githubgen in this repository (#37294)
  githubgen has moved to opentelemetry-go-build-tools. Please change your scripts to use this new location.

🚀 New components 🚀

• intervalprocessor: Interval Processor is now Alpha stability and is added to the contrib and k8s distributions (#36514)
• exporter/bmchelix: Add a new component for exporting metrics to BMC Helix (#36773)
• gitlabreceiver: Adds webhook skeleton to GitLab receiver to receive events from GitLab for tracing. (#35207)
  This PR adds a skeleton for the GitLab receiver to receive events from GitLab for tracing via a webhook. The trace portion of this receiver will run and respond to GET requests for the health check only.
• extension/skywalkingencodingextension: Support skywalking_encoding extension for skywalking traces. (#28693)

💡 Enhancements 💡

• mysqlreceiver: Add delete_multi, update_multi metrics to mysql.commands for mysqlreceiver (#37301)
• datadogexporter: Add a feature gate datadog.EnableReceiveResourceSpansV2. Enabling this gate uses a refactored implementation of OTLP->Datadog Span translation in datadogexporter and datadogconnector which improves performance by 10%, and deprecates the following functionality: - No longer checks for resource-related values (container, env, hostname) in span attributes. This previous behavior did not follow the OTel spec. (#37171)
• pkg/ottl: Add the Nanosecond converter to return the nanosecond component from the specified time.Time (#37042)
• pkg/ottl: Add the Second converter to return the second component from the specified time.Time (#37042)
• vcenterreceiver: Adds vCenter memory capacity for hosts and memory granted metric for VMs. (#37257)
• awss3exporter: Implement sending queue for S3 exporter (#37274, #36264)
• huaweicloudces: Move huaweicloudces receiver to alpha (#34953)
• cgroupruntimeextension: Implement ECS metadata retrieval for cgroupruntime extension. (#36814)
• deltatocumulativeprocessor: cap the number of exponential histogram buckets to 160 (#33277)
• resourcedetectionprocessor: This enhancement detects AWS EKS cloud account ID (#37179)
• elasticsearchexporter: Handle EventName for log records in OTel mode (#37011)
• elasticsearchexporter: More efficient JSON encoding for OTel mode (#37032)
  Increases throughput for metrics by 2x and for logs and traces by 3x
• elasticsearchexporter: Mark OTel mapping mode as stable (#37240)
  OTel mapping mode should no longer be considered unstable as there is no planned breaking change.
• googlecloudmonitoringreceiver: set the minimum collection interval as 60s (#36898)
• datadogexporter: Add a feature gate datadog.EnableOperationAndResourceNameV2. Enabling this gate modifies the logic for computing operation and resource names from OTLP spans to produce shorter, more readable names and improve alignment with OpenTelemetry specifications. (#36419)
• dorisexporter: send json lines to doris rather than json array (#36896)
• k8sattributesprocessor: For pods with only one container, the container.id and k8s.container.name are not longer required in the resource attributes to add the container attributes (#34189)
• logdedupprocessor: Add 'include_fields' option to deduplicate log records via body or attribute fields. (#36965)
• pkg/ottl: Enhanced error messages for invalid cache access and introduced options to configure their values within the OTTL contexts. (#29017)
• pkg/ottl: Add the FormatTime function to convert time.Time values to human-readable strings (#36870)
• prometheusremotewriteexporter: Re allows the configuration of multiple workers (#36134)
• receiver/prometheusremotewrite: Check if Scope is already present comparing with the received labels (#36927)
• extension/jaegerremotesampling: remove dependency on jaeger internal code (#36976)
• telemetrygen: Remove go-grpc-middleware dependency (#37103)
• resourcedetectionprocessor: Introduce kubeadm detector to retrieve local cluster name. (#35116)
• signalfxexporter: Prioritize retrieving token from context when accesstokenpassthrough is enabled (#37102)
• signaltometricsconnector: Add core logic for the signal to metrics connector to make it functional. (#35930)
• signaltometrics: Adds resource attributes based on telemetry settings to the connector to ensure single writer (#35930)
• tailsamplingprocessor: Added debug logging to the sampling decision caches. (#37038)
• tailsamplingprocessor: Improved not sampled decision cache usage and deleting traces from the internal map when they are in a decision cache. (#37189)

🧰 Bug fixes 🧰

• googlecloudpubsubreceiver: Fix a goroutine leak during shutdown. (#30438)
  A goroutine leak was found in the googlecloudpubsubreceiver.
  The goroutine leak was caused by the receiver not closing the underlying created gRPC client when using an insecure custom endpoint.

• signalfxexporter: Honor access_token_passthrough config option for sending events (#37102)

• clickhouseexporter: Fix Nil Pointer Exception on Metrics/Traces export without service.name Resource Attribute (#37030)

• k8sattributesprocessor: Ensure the pods gathered by the processor contain the information about their related replica sets and deployments after the initial sync (#37056)

• logdedupprocessor: Fix config validation not working when creating a processor. (#37278)

• pkg/ottl: Fix bug with replace_all_matches and replace_all_patterns that caused non-string values to be changed to empty string when matching against empty string. (#37071)

• tailsamplingprocessor: Fixed sampling policy evaluation debug logging batch metrics (e.g. sampled). (#37040)

• tailsamplingprocessor: Late span age histogram should include sampled traces. (#37180)

API changelog

🛑 Breaking changes 🛑

• routingconnector: Change match_once parameter from bool to *bool. (#29882)
  Boolean values should still unmarshal successfully, but direct instantiation in code will fail.
  The change allows us to check for usage and warn of the upcoming removal in v0.120.0.

💡 Enhancements 💡

• pkg/ottl: Enhanced error messages for invalid cache access and introduced options to configure their values within the OTTL contexts. (#29017)
• pkg/ottl: Add value expression parser that enables components using ottl to retrieve values from the output of an expression (#35621)
  the expression can be either a literal value, a path value within the context, or the result of a converter and/or a mathematical expression.
