open-telemetry/opentelemetry-go v1.23.0 on GitHub

This release contains the first stable, v1, release of the following modules:

See our versioning policy for more information about these stability guarantees.

Add WithEndpointURL option to the exporters/otlp/otlpmetric/otlpmetricgrpc, exporters/otlp/otlpmetric/otlpmetrichttp, exporters/otlp/otlptrace/otlptracegrpc and exporters/otlp/otlptrace/otlptracehttp packages. (#4808)
Experimental exemplar exporting is added to the metric SDK. See metric documentation for more information about this feature and how to enable it. (#4871)
ErrSchemaURLConflict is added to go.opentelemetry.io/otel/sdk/resource. This error is returned when a merge of two Resources with different (non-empty) schema URL is attempted. (#4876)

The Merge and New functions in go.opentelemetry.io/otel/sdk/resource now returns a partial result if there is a schema URL merge conflict. Instead of returning nil when two Resources with different (non-empty) schema URLs are merged the merged Resource, along with the new ErrSchemaURLConflict error, is returned. It is up to the user to decide if they want to use the returned Resource or not. It may have desired attributes overwritten or include stale semantic conventions. (#4876)

Fix ContainerID resource detection on systemd when cgroup path has a colon. (#4449)
Fix go.opentelemetry.io/otel/sdk/metric to cache instruments to avoid leaking memory when the same instrument is created multiple times. (#4820)
Fix missing Mix and Max values for go.opentelemetry.io/otel/exporters/stdout/stdoutmetric by introducing MarshalText and MarshalJSON for the Extrema type in go.opentelemetry.io/sdk/metric/metricdata. (#4827)
