v2.3.0-beta.1

• Update to OpenTelemetry 2.3.0

v2.2.0-beta.1

• Update to OpenTelemetry 2.2.0
  • The resource providers for Google Cloud and AWS are not enabled by default anymore.
    You can enable them using OTEL_RESOURCE_PROVIDERS_AWS_ENABLED=true and OTEL_RESOURCE_PROVIDERS_GCP_ENABLED=true.
  • Jetty is now supported in Spring Boot 3.2.

v2.1.0-beta.1

• Update to OpenTelemetry 2.1.0
  • Actuator instrumentation has been disabled by default. You can enable using
    OTEL_INSTRUMENTATION_SPRING_BOOT_ACTUATOR_AUTOCONFIGURE_ENABLED=true or
    -Dotel.instrumentation.spring-boot-actuator-autoconfigure.enabled=true.

v2.0.0-beta.1

• Update to OpenTelemetry 2.0.0
  • Many Breaking Changes, most notably:
    • The default OTLP protocol has been changed from grpc to http/protobuf in order to align with
      the specification.
      You can switch to the grpc protocol using OTEL_EXPORTER_OTLP_PROTOCOL=grpc
      or -Dotel.exporter.otlp.protocol=grpc.
    • Micrometer metric bridge has been disabled by default. You can enable it using
      OTEL_INSTRUMENTATION_MICROMETER_ENABLED=true
      or -Dotel.instrumentation.micrometer.enabled=true.
  • Stable JVM semantic conventions are now emitted by default - but this was already the case in 0.32.0-beta.1
    (via opt-in), so no change here.
• (Informational, not related to this release) Spring Boot 3.2 is supported, except for Jetty
  (see compatibility matrix).
• The following GRAFANA_* environment variables are now deprecated and will be removed in a future release.
  Please use OTEL_* environment variables instead
  (in the spirit of making it easy to migrate away from this distribution).
  • GRAFANA_OTLP_DEBUG_LOGGING and GRAFANA_OTLP_LOGGING_EXPORTER_ENABLED
    (details)
  • GRAFANA_CLOUD_INSTANCE_ID, GRAFANA_CLOUD_ZONE, and GRAFANA_CLOUD_API_KEY
    (details)

Full Changelog: v0.32.0-beta.1...v2.0.0-beta.1

v0.32.0-beta.1

• Update to OpenTelemetry 1.32.0
• Breaking Change: Use new JVM semantic conventions
• Breaking Change: Use telemetry.distro.name = grafana-opentelemetry-java
  and telemetry.distro.version = 0.32.0-beta.1 to identify this distribution instead of
  telemetry.sdk.name = grafana-opentelemetry-java and telemetry.sdk.version = 0.32.0
  (for reference: from now on telemetry.sdk.name = opentelemetry and telemetry.sdk.version = 1.32.0.

v0.31.0

• This is the first public preview release of this distribution which is released together with the public release of Grafana Cloud Application Observability.
• This release is based on OpenTelemetry 1.31.0 - so the version number becomes 0.31.0 (we'll switch to 1.x.y with the first GA release).
• No functional changes.

v0.3.0

• Add resource detectors for Google Cloud and AWS - mainly for Kubernetes monitoring.
• Add ability to drop metrics that are not needed for Application Observability (docs).
• Rename grafana cloud environment variables GRAFANA_OTLP_CLOUD_* to GRAFANA_CLOUD_*.
