  Affected components

  • routingprocessor
  • transformprocessor

• pkg/ottl: Add support for setting Maps in Values. This enables Contexts to set map values for attributes. (#16352)

• prometheusreceiver: Trim type's and unit's suffixes from metric name as per otel specs. (#8950)
  Can be enabled by the featuregate pkg.translator.prometheus.NormalizeName

• pkg/ottl: Remove duplicate parse IDs code, avoid coreinternal dependency (#16393)
  The "[trace|span]_id_string" func returns "000..000" string for invalid ids.

• exporter/signalfxexporter: Allow user to add a custom CA so the ingest and api clients can verify and communicate with custom TLS servers. (#16250)
  "ingest_tls" and "api_tls" can be used to set the absolute path to the CA file "ca_file".
  This is needed when the exporter is pointing to a TLS enabled signalfx receiver or/and TLS enabled http_forwarder
  and the CA is not in the system cert pool

• pkg/stanza: Support to Customize bufio.SplitFunc (#14593)

• processor/transform: Adds new configuration options that allow specifying the OTTL context to use when executing statements. See Transform Processor README for more details. (#15381)
  The existing configuration options will be deprecated in a future release.

• transformprocessor: Added OTTL function ConvertCase into the Transform Processor (#16083)

🧰 Bug fixes 🧰

• Fixes missed dependency updates in v0.65.0

• receiver/jaeger: Fix an error message in thrift HTTP message decoder (#16372)

• spanmetricsprocessor: Register processor.spanmetrics.PermissiveLabelSanitization featuregate, which was only defined but not registered. (#16269)

• splunkhecexporter: Apply max content length to compressed HEC content (#13995)
  The Splunk HEC exporter uses the unzipped content to check the size of the payload to send, instead of the compressed content.
  The max content length configuration should apply to the zipped content when compression is enabled.

• receiver/hostmetrics: Remove "Deprecated" label from network metrics (#16227)
  Replacement of the metrics was rejected some time ago, but the labels were not updated.

• mongodbatlasreceiver: Checks host and port before assigning attributes in poll mode (#16284)

• datadogexporter: Fixes crash when logging error on logs exporter (#16077)

• pkg/ottl: Fix list argument parsing when using internal arguments (#16298)

• pkg/stanza, filelog, journald, windowseventlog: Fix issue where specifying a non-existent storage extension caused panic during shutdown. (#16212)

• pkg/stanza: Fix severity range unmarshaling (#16339)

• splunkhecexporter: Do not log a warning on mapping empty metrics. (#3549)

• exporter/datadog: Fixes bug to append tags in attributes instead of replacing them, simplifies filelog receiver setup, and adds otel_source tag. (#15387)

• processor/transform: Fix issue where the metric context was using datapoint functions. (#16251)

• vcenterreceiver: collect VM may be panic nil pointer. (#16277)
