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)
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)
The base2 exponential histogram aggregation has been marked as stable. To use, configure
your MetricExporter with a default aggregation
of Aggregation.base2ExponentialBucketHistogram() for histogram instruments. If using OTLP
exporter with autoconfigure,
set OTEL_EXPORTER_OTLP_METRICS_DEFAULT_HISTOGRAM_AGGREGATION=BASE2_EXPONENTIAL_BUCKET_HISTOGRAM.
If using configuring OTLP programatically,
use Otlp*MetricExporterBuilder#setDefaultAggregationSelector(DefaultAggregationSelector).
The metrics SDK undergone significant internal refactoring which results in reduced complexity and
significantly reduced memory allocation during metric collection / export.

Logs
WARNING: Split out Event API from Log API. Event API is now published in opentelemetry-api-events.
API / SDK usage has also changed - see PR for details.
