Release v0.25.1

What's Changed

• Fixes broken pom by removing versionMapping by @psx95 in #242

Details

The broken POM change for exporter-auto in v0.25.0 has been fixed now.

Release 0.25.0

Changes Highlights

• With this release a shaded variant of the auto-exporter is being provided along with an un-shaded variant. The shaded jar is recommended when the auto-exporter required to be provided as an agent. This is a common use-case when using OTel auto-instrumentation.
• Fixed underlying bug with the exporters that caused OpenTelemetry to disable if this library was used with opencensus-shim (#141).
• Updated metric exporter to set label descriptors for metrics to type String if the default prefix - workload.googleapis.com is used (#159).
• Documentation updates and fixes to the examples that make them easier to run & follow.

Important - Broken Dependencies

• The non-shaded variant for exporter-auto has a broken POM, which will cause issues in a Maven project. Use the shaded variant instead.

Release 0.21.0

This release provides a preview of the stable metric-exporer for Java, additionally releasing alpha-versions of important OTEL components individually consumable.

GCP Propagators

This release includes a new maven artifact: com.google.cloud.opentelemetry:propagators-gcp. This provides hooks to leverage the X-Cloud-Trace-Context propagation header used by Google Cloud load balancers. See the readme for details.

GCP Resource Detection

This release includes a new maven artifact: com.google.cloud.opentelemetry:detector-resources. This provides hooks to detect GCP related resource attributes, e.g. cloud.platform.
See the readme for details.

Tracing Exporter Changes

This release includes some (possibly breaking) trace exporter changes. Specifically, the exporter will now include more attributes in spans by default, including instrumentation scope, resource and others.

Release 0.20.0

• Update to stable version of metrics API
• Breaking: Update + Fix monitored resource mapping for latest monitored resource usage in GKE.

Release 0.19.0
