• podmanreceiver: Adds metrics and resources metadata and sets seconds precision for cpu metrics (#​28640)

• clickhouseexporter: Add ServiceName as column into Clickhouse metrics tables (#​31670)
  It's a breaking change. users who upgrade to the latest version need to alter the Clickhouse table:

  ALTER TABLE otel_metrics_exponential_histogram ADD COLUMN ServiceName LowCardinality(String) CODEC(ZSTD(1));
  ALTER TABLE otel_metrics_gauge ADD COLUMN ServiceName LowCardinality(String) CODEC(ZSTD(1));
  ALTER TABLE otel_metrics_histogram ADD COLUMN ServiceName LowCardinality(String) CODEC(ZSTD(1));
  ALTER TABLE otel_metrics_sum ADD COLUMN ServiceName LowCardinality(String) CODEC(ZSTD(1));
  ALTER TABLE otel_metrics_summary ADD COLUMN ServiceName LowCardinality(String) CODEC(ZSTD(1));

• elasticsearchexporter: Initial pass in implementing the ecs mapping mode (#​31553)
  Breaking change if mapping mode is set to ecs, use none to maintain existing format

• pkg/stanza: Revert recombine operator's 'overwrite_with' default value. (#​30783)
  Restores the previous the default value of oldest, meaning that the recombine operator will emit the
  first entry from each batch (with the recombined field). This fixes the bug introduced by 30783 and restores
  the default setting so as to effectively cancel out the bug for users who were not using this setting.
  For users who were explicitly setting overwrite_with, this corrects the intended behavior.

• processor/attributes, processor/resource: Remove stable coreinternal.attraction.hash.sha256 feature gate. (#​31997)

• receiver/dockerstats: Remove stable receiver.dockerstats.useScraperV2 feature gate. (#​31999)

• awsxrayexporter: change x-ray exporter's translator to make "." split annotation pass as-is (#​31732)
  In the past, X-Ray doesn’t support “.”. So we have a translator in x-ray export to translates it to “_” before sending traces to X-Ray Service. | To match otel naming style, x-ray service team decide to change their service to support both "." type and "" type of naming. In this case the translator that translate "." to "" is no-longer needed. This PR change the way this translator work | X-Ray PMs agree on rolling out this change by using feature-gate

• exceptionsconnector: change stability of exceptionsconnector from development to alpha (#​31820)

• exceptionsconnector: Copy span attributes to the generated log from exception. (#​24410)

• prometheusreceiver: Allows receiving prometheus native histograms (#​26555)

  • Native histograms are compatible with OTEL exponential histograms.
  • The feature can be enabled via the feature gate receiver.prometheusreceiver.EnableNativeHistograms.
    Run the collector with the command line option --feature-gates=receiver.prometheusreceiver.EnableNativeHistograms.
  • Currently the feature also requires that targets are scraped via the ProtoBuf format.
    To start scraping native histograms, set
    config.global.scrape_protocols to [ PrometheusProto, OpenMetricsText1.0.0, OpenMetricsText0.0.1, PrometheusText0.0.4 ] in the
    receiver configuration. This requirement will be lifted once Prometheus can scrape native histograms over text formats.
  • For more up to date information see the README.md file of the receiver at
    https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/receiver/prometheusreceiver/README.md#prometheus-native-histograms.

  When enabled, the receiver.hostmetrics.normalizeProcessCPUUtilization feature gate will cause process.cpu.utilization values to be divided by the number of logical cores on the system. This is necessary to produce a value on the interval of [0-1], as the description of process.cpu.utilization the metric says.

• transformprocessor: Change metric unit for metrics extracted with extract_count_metric() to be the default unit (1) (#​31575)
  The original metric unit does not apply to extracted count metrics the same way it does to sum, min or max.

• kafkareceiver: standardizes the default topic name for metrics and logs receivers to the same topic name as the metrics and logs exporters of the kafkaexporter (#​27292)
  If you are using the Kafka receiver in a logs and/or a metrics pipeline
  and you are not customizing the name of the topic to read from with the topic property,
  the receiver will now read from otlp_logs or otlp_metrics topic instead of otlp_spans topic.
  To maintain previous behavior, set the topic property to otlp_spans.

• pkg/stanza: Entries are no longer logged during error conditions. (#​26670)
  This change is being made to ensure sensitive information contained in logs are never logged inadvertently.
  This change is a breaking change because it may change user expectations. However, it should require
  no action on the part of the user unless they are relying on logs from a few specific error cases.

• pkg/stanza: Invert recombine operator's 'overwrite_with' default value. (#​30783)
  Previously, the default value was oldest, meaning that the recombine operator should emit the
  first entry from each batch (with the recombined field). However, the actual behavior was inverted.
  This fixes the bug but also inverts the default setting so as to effectively cancel out the bug fix
  for users who were not using this setting. For users who were explicitly setting overwrite_with,
  this corrects the intended behavior.

🧰 Bug fixes 🧰

• basicauthextension: Accept empty usernames. (#​30470)
  Per https://datatracker.ietf.org/doc/html/rfc2617#section-2, username and password may be empty strings ("").
  The validation used to enforce that usernames cannot be empty.

• servicegraphconnector: update prefix to match the component type (#​31023)

• datadog/connector: Create a separate connector in the Datadog connector for the trace-to-metrics and trace-to-trace pipelines. It should reduce the number of conversions we do and help with Datadog connector performance. (#​30828)
  Simplify datadog/connector with two separate connectors in trace-to-metrics pipeline and trace-to-trace pipeline.

• datadogreceiver: Set AppVersion to allow Datadog version property to transform properly to service.version resource attribute (#​30225)

• cmd/opampsupervisor: Fix memory leak on shutdown (#​30438)

• exporter/datadog: Fixes a bug where empty histograms were not being sent to the backend in the distributions mode. (#​31019)

• pkg/ottl: Fix parsing of string escapes in OTTL (#​23238)

• pkg/stanza: Recombine operator should always recombine partial logs (#​30797)
  Previously, certain circumstances could result in partial logs being emitted without any
  recombiniation. This could occur when using is_first_entry, if the first partial log from
  a source was emitted before a matching "start of log" indicator was found. This could also
  occur when the collector was shutting down.

• pkg/stanza: Fix bug where recombine operator's 'overwrite_with' condition was inverted. (#​30783)

• exporter/signalfx: Use "unknown" value for the environment correlation calls as fallback. (#​31052)
  This fixed the APM/IM correlation in the Splunk Observability UI for the users that send traces with no "deployment.environment" resource attribute value set.

• namedpipereceiver: Fix SIGSEGV when named pipe creation fails (#​31088)
