API

  • WARNING: GlobalOpenTelemetry trigger of autoconfiguration is now opt-in. Previously, GlobalOpenTelemetry.get triggered autoconfiguration if opentelemetry-sdk-extension-autoconfigure was detected on the classpath. That behavior is now opt-in by setting environment variable OTEL_JAVA_GLOBAL_AUTOCONFIGURE_ENABLED=true. (#5010)
  • Update LoggerBuilder, MeterBuilder, TracerBuilder javadoc (#5050)

Context

  • Make closing scope idempotent and non-operational when corresponding context is not current. (#5061)

SDK

  • Standardize internal usage of ConfigUtil for reading environment variables and system properties (#5048)

Metrics

  • Lazily initialize exponential histogram buckets (#5023)
  • Delete MapCounter alternative exponential histogram implementation (#5047)
  • Add toString to SdkMeter, SdkObservableInstrument, AbstractInstrumentBuilder (#5072)

Exporter

  • OtlpGrpcSpanExporter, OtlpHttpSpanExporter, OtlpGrpcLogRecordExporter, OtlpHttpLogRecordExporter, ZipkinSpanExporter, and JaegerGrpcSpanExporter are now instrumented with GlobalOpenTelemetry by default. Instrumentation initializes lazily to prevent ordering issue of accessing GlobalOpenTelemetry.get before GlobalOpenTelemetry.set is called. (#4993)
  • Add ConfigurableSpanExporterProvider implementation for JaegerGrpcSpanExporter (#5002)
  • Add ConfigurableSpanExporterProvider, ConfigurableMetricExporterProvider, ConfigurableLogRecordExporterProvider for OtlpGrpc{Signal}Exporters and OtlpHttp{SignalExporters (#5003)
  • Replace OTLP User-Agent spaces with dashes (#5080)
  • Add AutoConfigurationCustomizerProvider implementation for PrometheusHttpServer (#5053)
  • Add resource target_info and scope target_info metrics to PrometheusHttpServer in compliance with spec (#5039)
  • Drop delta metrics in PrometheusHttpServer (#5062)
  • PrometheusHttpServer drops metrics with same name and different type (#5078)

SDK Extensions

  • DEPRECATION: Align autoconfigure exemplar filter names with spec. Previous names none, all, with_sampled_trace are deprecated. Use always_off, always_on, trace_based instead. (#5063)

OpenTracing Shim

  • Add createTracerShim function (#4988)
