Releases and Updates

Here are the latest updates from some of our core repositories.

Specification

Version 1.24 includes metrics and logs.

Collector

Version 0.84.0 has been released, along with 0.83.

Notable user-facing changes include:

• loggingexporter now supports exemplars logging when the verbosity level is set to detailed.
• configgrpc now allows the use of any registered gRPC load balancer name.
• Internal traces can now be exported via OTLP.
• configgrpc now supports the :authority pseudo-header in gRPC client.

In addition, there’s a variety of bug fixes and changes in the Collector API for exporters.

collector-contrib includes many updates – be sure to check the release notes.

There are several user-facing changes, including breaking changes:

• The jaegerreceiver has deprecated the remote_sampling config. It will now fail to start if the config is specified. In a future version, this feature will be removed and the receiver will always fail when the config is specified.
• The googlecloudexporter has removed the retry_on_failure config, as it caused issues when handling retries.
• The Datadog processor has been deprecated in favor of the Datadog connector.
• The Tanzu Observability (Wavefront) Exporter has been deprecated in favor of native OTLP ingestion.
• The redisreceiver now supports adding a username parameter for connecting to Redis.
• The postgresqlreceiver has added the postgresql.temp_files metric.
• The receiver/azuremonitor has added new attributes to metrics like name, type, and resource_group.
