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.
