+### 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)
+
+### Deprecated
+
+- The `NewMetricExporter` in `go.opentelemetry.io/otel/bridge/opencensus` is deprecated.
+  Use `NewMetricProducer` instead. (#3541)
+- The `go.opentelemetry.io/otel/metric/instrument/asyncfloat64` package is deprecated.
