This release targets the OpenTelemetry SDK 1.55.0.
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.
⚠️ Breaking Changes
- Hadoop JMX metrics have been renamed to align with semantic conventions. If you are using Hadoop JMX metrics, you will need to update your dashboards and alerts. (#14411)
- Lettuce 5.1 instrumentation now aligns with other instrumentations and no longer sets the span status description. (#14886)
🚫 Deprecations
- The following Logback appender configuration properties have been renamed for clarity. The old property names have been deprecated and will be removed in a future release: - Java agent:
otel.instrumentation.logback-appender.experimental.capture-logstash-attributes→otel.instrumentation.logback-appender.experimental.capture-logstash-marker-attributes- Spring Boot starterotel.instrumentation.logback-appender.experimental.capture-logstash-markers→otel.instrumentation.logback-appender.experimental.capture-logstash-marker-attributes- Logback appender configuration property:captureLogstashAttributes→captureLogstashMarkerAttributes- Logback appender API:setCaptureLogstashAttributes()→setCaptureLogstashMarkerAttributes()(#14959)
