Version 0.12.0

This update is compatible with the OpenTelemetry Java SDK 0.12.0. Most breaking changes in its API are API-compatible if you recompile your app.

NB: The snapshots repository has been moved to Sonatype OSS (https://oss.sonatype.org/content/repositories/snapshots/)

🌟 New instrumentation

• gRPC instrumentation has been updated to support the latest version #1839

📈 Improvements

• Context is propagated even when there is no span in more locations #1802 #1810 #1811
• WithSpan will not produce nested server or client spans anymore #1801
• Standard Resource extensions for process and runtime are enabled automatically #1809
• HTTP attributes are populated for AWS Lambda spans #1780
• Additional FaaS spans are populated for AWS Lambda #1831

🛠️ Bug fixes

• AWS SDK suppresses client spans, preventing authentication signature break #1837

🧰 Tooling

• A new matrix of tests of various app servers has been added #1821
• We now publish the instrumentation artifacts to Maven Central #1823

☢️ Breaking changes

• servlet.context span attribute is not set anymore #1783

• Some configuration properties have been renamed #1786

otel.instrumentation.executors.includeAll --> otel.instrumentation.executors.include-all
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

• Several custom attributes have been renamed to be prefixed by instrumentation name. If any of these seem interesting to formalize, let us know or go ahead and file a specification issue! #1784

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
