Added

• The WithView Option is added to the go.opentelemetry.io/otel/sdk/metric package.
  This option is used to configure the view(s) a MeterProvider will use for all Readers that are registered with it. (#3387)
• Add Instrumentation Scope and Version as info metric and label in Prometheus exporter.
  This can be disabled using the WithoutScopeInfo() option added to that package.(#3273, #3357)
• OTLP exporters now recognize: (#3363)
  • OTEL_EXPORTER_OTLP_INSECURE
  • OTEL_EXPORTER_OTLP_TRACES_INSECURE
  • OTEL_EXPORTER_OTLP_METRICS_INSECURE
  • OTEL_EXPORTER_OTLP_CLIENT_KEY
  • OTEL_EXPORTER_OTLP_TRACES_CLIENT_KEY
  • OTEL_EXPORTER_OTLP_METRICS_CLIENT_KEY
  • OTEL_EXPORTER_OTLP_CLIENT_CERTIFICATE
  • OTEL_EXPORTER_OTLP_TRACES_CLIENT_CERTIFICATE
  • OTEL_EXPORTER_OTLP_METRICS_CLIENT_CERTIFICATE
• The View type and related NewView function to create a view according to the OpenTelemetry specification are added to go.opentelemetry.io/otel/sdk/metric.
  These additions are replacements for the View type and New function from go.opentelemetry.io/otel/sdk/metric/view. (#3459)
• The Instrument and InstrumentKind type are added to go.opentelemetry.io/otel/sdk/metric.
  These additions are replacements for the Instrument and InstrumentKind types from go.opentelemetry.io/otel/sdk/metric/view. (#3459)
• The Stream type is added to go.opentelemetry.io/otel/sdk/metric to define a metric data stream a view will produce. (#3459)
• The AssertHasAttributes allows instrument authors to test that datapoints returned have appropriate attributes. (#3487)

Changed

• The "go.opentelemetry.io/otel/sdk/metric".WithReader option no longer accepts views to associate with the Reader.
  Instead, views are now registered directly with the MeterProvider via the new WithView option.
  The views registered with the MeterProvider apply to all Readers. (#3387)
• The Temporality(view.InstrumentKind) metricdata.Temporality and Aggregation(view.InstrumentKind) aggregation.Aggregation methods are added to the "go.opentelemetry.io/otel/sdk/metric".Exporter interface. (#3260)
• The Temporality(view.InstrumentKind) metricdata.Temporality and Aggregation(view.InstrumentKind) aggregation.Aggregation methods are added to the "go.opentelemetry.io/otel/exporters/otlp/otlpmetric".Client interface. (#3260)
• The WithTemporalitySelector and WithAggregationSelector ReaderOptions have been changed to ManualReaderOptions in the go.opentelemetry.io/otel/sdk/metric package. (#3260)
• The periodic reader in the go.opentelemetry.io/otel/sdk/metric package now uses the temporality and aggregation selectors from its configured exporter instead of accepting them as options. (#3260)

Fixed

• The go.opentelemetry.io/otel/exporters/prometheus exporter fixes duplicated _total suffixes. (#3369)
• Remove comparable requirement for Readers. (#3387)
• Cumulative metrics from the OpenCensus bridge (go.opentelemetry.io/otel/bridge/opencensus) are defined as monotonic sums, instead of non-monotonic. (#3389)
• Asynchronous counters (Counter and UpDownCounter) from the metric SDK now produce delta sums when configured with delta temporality. (#3398)
• Exported Status codes in the go.opentelemetry.io/otel/exporters/zipkin exporter are now exported as all upper case values. (#3340)
• Aggregations from go.opentelemetry.io/otel/sdk/metric with no data are not exported. (#3394, #3436)
• Reenabled Attribute Filters in the Metric SDK. (#3396)
• Asynchronous callbacks are only called if they are registered with at least one instrument that does not use drop aggragation. (#3408)
• Do not report empty partial-success responses in the go.opentelemetry.io/otel/exporters/otlp exporters. (#3438, #3432)
• Handle partial success responses in go.opentelemetry.io/otel/exporters/otlp/otlpmetric exporters. (#3162, #3440)
• Prevent duplicate Prometheus description, unit, and type. (#3469)
• Prevents panic when using incorrect attribute.Value.As[Type]Slice(). (#3489)

Removed

• The go.opentelemetry.io/otel/exporters/otlp/otlpmetric.Client interface is removed. (#3486)
• The go.opentelemetry.io/otel/exporters/otlp/otlpmetric.New function is removed. Use the otlpmetric[http|grpc].New directly. (#3486)

Deprecated

• The go.opentelemetry.io/otel/sdk/metric/view package is deprecated.
  Use Instrument, InstrumentKind, View, and NewView in go.opentelemetry.io/otel/sdk/metric instead. (#3476)
