End User Changelog

🛑 Breaking changes 🛑

• awsfirehosereceiver: Follow receiver contract based on type of error (#5909)

• elasticsearchexporter: Respect flush::bytes in sync bulk indexer, flush::bytes measures uncompressed size, change default batcher::max_size_items to 0 (#36163)
  Limit the bulk request size to roughly flush::bytes for sync bulk indexer. Sync bulk indexer is used when batcher::enabled is either true or false. In order words, sync bulk indexer is not used when batcher config is undefined. Change flush::bytes to always measure in uncompressed bytes. Change default batcher::max_size_items to 0 as bulk request size limit is now more effectively enforced by flush::bytes.

• k8sattributesprocessor: Move k8sattr.fieldExtractConfigRegex.disallow feature gate to Beta. (#25128)
  Disable the k8sattr.fieldExtractConfigRegex.disallow feature gate to get the old behavior.

• internal: Remove stable gate component.UseLocalHostAsDefaultHost (#36589)

• cmd/opampsupervisor: Update default logger output paths to stderr (#36072)
  The default output paths for the opamp supervisor logger have been updated to stderr from [stdout, stderr].

• opampsupervisor: Enable strict unmarshalling of the OpAMP Supervisor config file. An error will now be returned if an invalid config key is set. (#35838)

🚩 Deprecations 🚩

• postgresqlreceiver: Minimal supported PostgreSQL version updated from 9.6 to 13.0 (#30923)
  Aligning on the supported versions as can be seen in the PostgreSQL releases section
• exporter/prometheusremotewrite: Change exporter.prometheusremotewriteexporter.deprecateCreatedMetric feature gate from Alpha to Beta version. (#35003)
  The export_created_metric configuration parameter is now ignored by default.

🚀 New components 🚀

• signaltometricsconnector: New component for generating metrics from raw signals using user defined OTTL expressions. (#35930)
• extension/cgroupruntime: Initial implementation for cgroupruntime extension. (#30289)
• huaweicloudcesreceiver: Introduce new receiver fetching data from huawei Cloud Eye Service. (#34953)
• netflowreceiver: Introduce the netflow receiver (#32732)

💡 Enhancements 💡

• datadogexporter: Add a configurable reporter_period parameter to the Datadog exporter’s host metadata configuration to allow users to specify the frequency at which host metadata is sent to Datadog. (#36450)

• awsemfexporter: Add support for 1 second metric resolution in CloudWatch Embedded Metrics Format based on metric attributes (#29506)

• awsemfexporter: Improvement unit conversion during EMF log translation (#35937)

• sumologicexporter: adding new products for auto discovery (#35622)

• postgresqlreceiver: Added new postgresql metrics to acheive parity with Telegraf (#36528)

• loadbalancingexporter: Adding sending_queue, retry_on_failure and timeout settings to loadbalancing exporter configuration (#35378, #16826)
  When switching to top-level sending_queue configuration - users should carefully review queue size
  In some rare cases setting top-level queue size to n*queueSize might be not enough to prevent data loss

• pkg/stanza: Introduce active file grouping mechanism. (#23787)

• receivercreator: Add support for starting receivers/scrapers based on provided annotations' hints for metrics' collection (#34427)

• tailsamplingprocessor: Adds decision cache for non-sampled trace IDs (#31583)

• cmd/opampsupervisor: Support environment variable expansion in the OpAMP supervisor config. (#36269)

• pkg/ottl: Move debug log to Statement.Execute so that components using it instead of StatementSequence also get debug logs. (#36456)

• routingconnector: Add abiilty to route by 'datapoint' context (#36523)

• signalfxreceiver: Follow receiver contract based on type of error (#5909)
  Use 503 error code for retryable and 400 error code for not-retryable errors instead of responding with a 500 unconditionally.

🧰 Bug fixes 🧰

• cmd/opampsupervisor: Do not log err if the last received doesn't exist (#36013)

• receiver/azureeventhub: When using a storage extension, the component will call Close on the client during component shutdown. This fixes a bug that resulted in a file potentially remaining locked after component shutdown. (#36238)

• azuremonitorexporter: Fixes an issue where the Azure Monitor exporter was not sending data to App Insights due to the Telemetry Channel not being flushed. (#35037)

• exporter/pulsarexporter: Change configuration option map_connections_per_broker, rename to max_connections_per_broker. (#36579)

• failoverconnector: Resolves a bug that prevents proper recovery when disabling max retries (#36587)

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

• processor/k8sattribute: fixes parsing of k8s image names to support images with tags and digests. (#36131)

• clickhouseexporter: Fix incorrect Resource Attribute service.name translation to ClickHouse ServiceName field for Logs Records (#36349)

• awsfirehosereceiver: fix timestamp when ingesting logs from CloudWatch through firehose (#36122)

• pkg/ottl: Allow indexing []int64, []float64, []bool, and []byte slices (#29441)
  It should now be possible to index all slice types

• opencensusreceiver: Do not report error message when OpenCensus receiver is shutdown cleanly. (#36622)

• loadbalancingexporter: The k8sresolver in loadbalancingexporter was triggering exporter churn in the way the change event was handled. (#35658)

• vcenterreceiver: The existing code did not honor TLS settings beyond 'insecure'. All TLS client config should now be honored. (#36482)
