+
+### Changed
+
+- Jaeger and Zipkin exporter use `github.com/go-logr/logr` as the logging interface, and add the `WithLogr` option. (#3497, #3500)
+- Instrument configuration in `go.opentelemetry.io/otel/metric/instrument` is split into specific options and confguration based on the instrument type. (#3507)
+  - Use the added `Int64Option` type to configure instruments from `go.opentelemetry.io/otel/metric/instrument/syncint64`.
+  - Use the added `Float64Option` type to configure instruments from `go.opentelemetry.io/otel/metric/instrument/syncfloat64`.
+  - Use the added `Int64ObserverOption` type to configure instruments from `go.opentelemetry.io/otel/metric/instrument/asyncint64`.
+  - Use the added `Float64ObserverOption` type to configure instruments from `go.opentelemetry.io/otel/metric/instrument/asyncfloat64`.
+- Return a `Registration` from the `RegisterCallback` method of a `Meter` in the `go.opentelemetry.io/otel/metric` package.
+  This `Registration` can be used to unregister callbacks. (#3522)
+- Global error handler uses an atomic value instead of a mutex. (#3543)
+- Add `NewMetricProducer` to `go.opentelemetry.io/otel/bridge/opencensus`, which can be used to pass OpenCensus metrics to an OpenTelemetry Reader. (#3541)
+- Global logger uses an atomic value instead of a mutex. (#3545)
+- The `Shutdown` method of the `"go.opentelemetry.io/otel/sdk/trace".TracerProvider` releases all computational resources when called the first time. (#3551)
+- The `Sampler` returned from `TraceIDRatioBased` `go.opentelemetry.io/otel/sdk/trace` now uses the rightmost bits for sampling decisions.
+  This fixes random sampling when using ID generators like `xray.IDGenerator` and increasing parity with other language implementations. (#3557)
+- Errors from `go.opentelemetry.io/otel/exporters/otlp/otlptrace` exporters are wrapped in erros identifying their signal name.
+  Existing users of the exporters attempting to identify specific errors will need to use `errors.Unwrap()` to get the underlying error. (#3516)
+- Exporters from `go.opentelemetry.io/otel/exporters/otlp` will print the final retryable error message when attempts to retry time out. (#3514)
+- The instrument kind names in `go.opentelemetry.io/otel/sdk/metric` are updated to match the API. (#3562)
+  - `InstrumentKindSyncCounter` is renamed to `InstrumentKindCounter`
+  - `InstrumentKindSyncUpDownCounter` is renamed to `InstrumentKindUpDownCounter`
+  - `InstrumentKindSyncHistogram` is renamed to `InstrumentKindHistogram`
+  - `InstrumentKindAsyncCounter` is renamed to `InstrumentKindObservableCounter`
+  - `InstrumentKindAsyncUpDownCounter` is renamed to `InstrumentKindObservableUpDownCounter`
+  - `InstrumentKindAsyncGauge` is renamed to `InstrumentKindObservableGauge`
+- The `RegisterCallback` method of the `Meter` in `go.opentelemetry.io/otel/metric` changed.
+  - The named `Callback` replaces the inline function parameter. (#3564)
+  - `Callback` is required to return an error. (#3576)
+  - `Callback` accepts the added `Observer` parameter added.
+    This new parameter is used by `Callback` implementations to observe values for asynchronous instruments instead of calling the `Observe` method of the instrument directly. (#3584)
+  - The slice of `instrument.Asynchronous` is now passed as a variadic argument. (#3587)
+- The exporter from `go.opentelemetry.io/otel/exporters/zipkin` is updated to use the `v1.16.0` version of semantic conventions.
+  This means it no longer uses the removed `net.peer.ip` or `http.host` attributes to determine the remote endpoint.
+  Instead it uses the `net.sock.peer` attributes. (#3581)
+- The `Min` and `Max` fields of the `HistogramDataPoint` in `go.opentelemetry.io/otel/sdk/metric/metricdata` are now defined with the added `Extrema` type instead of a `*float64`. (#3487)
+
+### Fixed
+
+- Asynchronous instruments that use sum aggregators and attribute filters correctly add values from equivalent attribute sets that have been filtered. (#3439, #3549)
+- The `RegisterCallback` method of the `Meter` from `go.opentelemetry.io/otel/sdk/metric` only registers a callback for instruments created by that meter.
+  Trying to register a callback with instruments from a different meter will result in an error being returned. (#3584)
+

+
+### 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 `Reader`s 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_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 `Reader`s. (#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` `ReaderOption`s have been changed to `ManualReaderOption`s 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 `Reader`s. (#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)

+- Reenabled Attribute Filters in the Metric SDK. (#3396)

+
+### 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)
