• Export the PeriodicReader struct in go.opentelemetry.io/otel/sdk/metric. (#4244)
• Add support for exponential histogram aggregations.
  A histogram can be configured as an exponential histogram using a view with "go.opentelemetry.io/otel/sdk/metric".ExponentialHistogram as the aggregation. (#4245)

• Add WithoutCounterSuffixes option in go.opentelemetry.io/otel/exporters/prometheus to disable addition of _total suffixes. (#4306)
• Add info and debug logging to the metric SDK in go.opentelemetry.io/otel/sdk/metric. (#4315)
• The go.opentelemetry.io/otel/semconv/v1.21.0 package.
  The package contains semantic conventions from the v1.21.0 version of the OpenTelemetry Semantic Conventions. (#4362)
• Accept 201 to 299 HTTP status as success in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp and go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp. (#4365)
• Document the Temporality and Aggregation methods of the "go.opentelemetry.io/otel/sdk/metric".Exporter" need to be concurrent safe. (#4381)
• Expand the set of units supported by the Prometheus exporter, and don't add unit suffixes if they are already present in go.opentelemetry.op/otel/exporters/prometheus (#4374)
• Move the Aggregation interface and its implementations from go.opentelemetry.io/otel/sdk/metric/aggregation to go.opentelemetry.io/otel/sdk/metric. (#4435)
• The exporters in go.opentelemetry.io/otel/exporters/otlp/otlpmetric now support the OTEL_EXPORTER_OTLP_METRICS_DEFAULT_HISTOGRAM_AGGREGATION environment variable. (#4437)
• Add the NewAllowKeysFilter and NewDenyKeysFilter functions to go.opentelemetry.io/otel/attribute to allow convenient creation of allow-keys and deny-keys filters. (#4444)

Changed

• NewManualReader in go.opentelemetry.io/otel/sdk/metric returns *ManualReader instead of Reader. (#4244)
• NewPeriodicReader in go.opentelemetry.io/otel/sdk/metric returns *PeriodicReader instead of Reader. (#4244)
• Count the Collect time in the PeriodicReader timeout in go.opentelemetry.io/otel/sdk/metric. (#4221)
• The function New in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc returns *Exporter instead of "go.opentelemetry.io/otel/sdk/metric".Exporter. (#4272)
• The function New in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp returns *Exporter instead of "go.opentelemetry.io/otel/sdk/metric".Exporter. (#4272)

• Restrict Meters in go.opentelemetry.io/otel/sdk/metric to only register and collect instruments it created. (#4333)
• PeriodicReader.Shutdown and PeriodicReader.ForceFlush in go.opentelemetry.io/otel/sdk/metric now apply the periodic reader's timeout to the operation if the user provided context does not contain a deadline. (#4356, #4377)
• Upgrade all use of go.opentelemetry.io/otel/semconv to use v1.21.0. (#4408)
