• (Contrib) oracledbreceiver: Fix incorrect values being set for oracledb.tablespace_size.limit and oracledb.tablespace_size.usage (#31451)
  • Please grant the DBA_TABLESPACE_USAGE_METRICS permission to the user connecting to the Oracle DB instance to ensure all enabled metrics are properly ingested.
• (Contrib) pkg/stanza: Revert recombine operator's 'overwrite_with' default value. (#30783)
• (Contrib) processor/attributes, processor/resource: Remove stable coreinternal.attraction.hash.sha256 feature gate. (#31997)

🚩 Deprecations 🚩

• (Contrib) postgresqlreceiver: Minimal supported PostgreSQL version will be updated from 9.6 to 12.0 in a future release. (#30923)
  Aligning on the supported versions as can be seen in the PostgreSQL releases section

🚀 New components 🚀

• (Splunk) Add SQL Server receiver (#4649)

💡 Enhancements 💡

• (Splunk) Automatically set splunk_otlp_histograms: true for collector telemetry exported via signalfx metrics exporter (#4655)
• (Splunk) Windows installer now removes the unused configuration files from the installation directory (#4645)
• (Core) otlpexporter: Checks for port in the config validation for the otlpexporter (#9505)
• (Core) service: Validate pipeline type against component types (#8007)
• (Contrib) ottl: Add new Unix function to convert from epoch timestamp to time.Time (#27868)
• (Contrib) filelogreceiver: When reading a file on filelogreceiver not on windows, if include_file_owner_name is true, it will add the file owner name as the attribute log.file.owner.name and if include_file_owner_group_name is true, it will add the file owner group name as the attribute log.file.owner.group.name. (#30775)
• (Contrib) - 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.
• (Contrib) spanmetricsconnector: Change default value of metrics_flush_interval from 15s to 60s (#31776)
• (Contrib) pkg/ottl: Adding a string converter into pkg/ottl (#27867)
• (Contrib) loadbalancingexporter: Support the timeout period of k8s resolver list watch can be configured. (#31757)
