NOTICE: This release contains a significant restructuring of the experimental event API and the API incubator artifact. Please read the notes in the API -> Incubator section carefully.
BREAKING: Rename opentelemetry-extension-incubator to opentelemetry-api-incubator, merge opentelemetry-api-events into opentelemetry-api-incubator. (#6289)
BREAKING: Remove domain from event api. EventEmitterProvider#setEventDomain has been removed. The event.name field should now be namespaced to avoid collisions. See Semantic Conventions for Event Attributes for more details. (#6253)
BREAKING: Rename EventEmitter and related classes to EventLogger. (#6316)
BREAKING: Refactor Event API to reflect spec changes. Restructure API to put fields in the AnyValue log record body. Add setters for timestamp, context, and severity. Set default severity to INFO=9. (#6318)
SDK
Add get{Signal}Exporter methods to Simple{Signal}Processor, Batch{Signal}Processor. (#6078)
Metrics
Use synchronized instead of reentrant lock in explicit bucket histogram (#6309)
Bugfix: Use getPrometheusName for Otel2PrometheusConverter map keys to avoid metric name conflicts (#6308)
Extensions
Add Metric exporter REUSABLE_DATA memory mode configuration options, including autoconfigure support via env var OTEL_JAVA_EXPERIMENTAL_EXPORTER_MEMORY_MODE=REUSABLE_DATA. (#6304)
Add autoconfigure console alias for logging exporter (#6027)
Update jaeger autoconfigure docs to point to OTLP (#6307)
Add ServiceInstanceIdResourceProvider implementation for generating service.instance.id UUID if not already provided by user. Included in opentelemetry-sdk-extension-incubator. (#6226)
Add GCP resource detector to list of resource providers in autoconfigure docs (#6336)
