This release targets the OpenTelemetry SDK 1.34.1.
Note that many artifacts have the -alpha suffix attached to their version number, reflecting that they are still alpha quality and will continue to have breaking changes. Please see the VERSIONING.md for more details.
The 2.0.0 release contains significant breaking changes that will most likely affect all users, please be sure to read the breaking changes below carefully.
Note: 1.32.x will be security patched for at least 6 months in case some of the changes below are too disruptive to adopt right away.
⚠️⚠️ Breaking changes ⚠️⚠️
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.
The OTLP logs exporter is now enabled by default. You can disable it using OTEL_LOGS_EXPORTER=none or -Dotel.logs.exporter=none.
Controller spans are now disabled by default. You can enable them using OTEL_INSTRUMENTATION_COMMON_EXPERIMENTAL_CONTROLLER_TELEMETRY_ENABLED=true or -Dotel.instrumentation.common.experimental.controller-telemetry.enabled=true.
View spans are now disabled by default. You can enable them using OTEL_INSTRUMENTATION_COMMON_EXPERIMENTAL_VIEW_TELEMETRY_ENABLED=true or -Dotel.instrumentation.common.experimental.view-telemetry.enabled=true.
⚠️⚠️ Stable HTTP semantic conventions are now emitted ⚠️⚠️
