Version 0.14.0

This update is compatible with the OpenTelemetry Java SDK 0.14.1. Most breaking changes are in the SDK so if you are using library instrumentation and the SDK directly, you may need to update code for initializing the SDK.

• Spring batch chunks #1850
• Spring batch partitioning #2034
• App-server specific runtimes
  • Undertow #1917
  • Liberty #1929
  • Jetty #2029

📈 Improvements

• Grizzy spans have exceptions added #1987
• AWS Lambda flush timeout can be configured #1960
• Context propagation for apache camel instrumentation #2042
• Netty instrumentation adds exceptions #2027
• Logging exporter outputs one span per line instead of combining a batch #2054
• Lambda SQS users do not need to configure xray as their app propagators anymore #2056
• Armeria instrumentation updated to target 1.3.0 which had breaking changes

🛠️ Bug fixes

• External exporter JAR file is closed correctly during initialization #1970
• Correctly propagate context in Jetty #1966
• Correctly handle servlet2 response with unset status #1985
• Agent logs its version at startup again #2026

🧰 Tooling

Version 0.13.0

This update is compatible with the OpenTelemetry Java SDK 0.13.1. Most breaking changes are in the SDK so if you are using library instrumentation and the SDK directly, you may need to update code for initializing the SDK.

🌟 New instrumentation

• Context propagation for Spring SimpleAsyncTaskExecutor #1897
• Spring batch jobs #1843
• Tomcat server handlers for more precise instrumentation vs generic servlet #1902
• OpenTelemetry baggage is now bridged and can be used in apps #1927

• SPI resources injected by instrumentation now detected by muzzle #1918
• Muzzle warnings correctly logged in tests #1930

☢️ Breaking changes

• Attributes that are not part of the opentelemetry specification have been hidden behind opt-in flags. If there are any attributes that you think would be great for anyone, please file an issue on the spec repo for adding them natively.

Flag guards are per instrumentation

• Hytrix: otel.instrumentation.hystrix.experimental-span-attributes
• Kafka: otel.instrumentation.kafka.experimental-span-attributes
• Spring Webflux: otel.instrumentation.spring-webflux.experimental-span-attributes

otel.hystrix.tags.enabled --> otel.instrumentation.hystrix.tags
otel.kafka.client.propagation.enabled --> otel.instrumentation.kafka.client-propagation
otel.instrumentation.defaultEnabled --> otel.instrumentation.default-enabled

Instrumentation affected: apache-camel, couchbase, grpc, jaxrs, kafka-clients, lettuce, rabbitmq, spring

• Exporter packages use exporter instead of exporters in artifact name, e.g., opentelemetry-javaagent-exporter-zipkin
