+- Added `resource.Default()` for use with meter and tracer providers. (#1507)
+- `AttributePerEventCountLimit` and `AttributePerLinkCountLimit` for `SpanLimits`. (#1535)
+- Added `Keys()` method to `propagation.TextMapCarrier` and `propagation.HeaderCarrier` to adapt `http.Header` to this interface. (#1544)
+- Added `code` attributes to `go.opentelemetry.io/otel/semconv` package. (#1558)
+- Compatibility testing suite in the CI system for the following systems. (#1567)

+### Changed
+
+- Replaced interface `oteltest.SpanRecorder` with its existing implementation
+  `StandardSpanRecorder` (#1542).
+- Default span limit values to 128. (#1535)
+- Rename `MaxEventsPerSpan`, `MaxAttributesPerSpan` and `MaxLinksPerSpan` to `EventCountLimit`, `AttributeCountLimit` and `LinkCountLimit`, and move these fields into `SpanLimits`. (#1535)
+- Renamed the `otel/label` package to `otel/attribute`. (#1541)
+- Vendor the Jaeger exporter's dependency on Apache Thrift. (#1551)
+- Parallelize the CI linting and testing. (#1567)
+- Stagger timestamps in exact aggregator tests. (#1569)
+- Changed all examples to use `WithBatchTimeout(5 * time.Second)` rather than `WithBatchTimeout(5)`. (#1621)
+- Prevent end-users from implementing some interfaces (#1575)

+- The `test-benchmark` is no longer a dependency of the `precommit` make target. (#1567)
+- Removed the `test-386` make target.
+   This was replaced with a full compatibility testing suite (i.e. multi OS/arch) in the CI system. (#1567)
+
+### Fixed
+
+- The sequential timing check of timestamps in the stdout exporter are now setup explicitly to be sequential (#1571). (#1572)
+- Windows build of Jaeger tests now compiles with OS specific functions (#1576). (#1577)
+- The sequential timing check of timestamps of go.opentelemetry.io/otel/sdk/metric/aggregator/lastvalue are now setup explicitly to be sequential (#1578). (#1579)

+### Changed
+
+- Rename project default branch from `master` to `main`. (#1505)

+- Move metric-related public global APIs from otel to otel/metric/global. (#1528)
+
+## Fixed
+
+- Fixed otlpgrpc reconnection issue.
+- The example code in the README.md of `go.opentelemetry.io/otel/exporters/otlp` is moved to a compiled example test and used the new `WithAddress` instead of `WithEndpoint`. (#1513)
+- The otel-collector example now uses the default OTLP receiver port of the collector.
