+### Added
+
+- Add `WithProxy` option in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`. (#4906)
+- Add `WithProxy` option in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlptracehttp`. (#4906)
+- Add `AddLink` method to the `Span` interface in `go.opentelemetry.io/otel/trace`. (#5032)
+- The `Enabled` method is added to the `Logger` interface in `go.opentelemetry.io/otel/log`.
+  This method is used to notify users if a log record will be emitted or not. (#5071)
+- Add `SeverityUndefined` `const` to `go.opentelemetry.io/otel/log`.
+  This value represents an unset severity level. (#5072)
+- Add `Empty` function in `go.opentelemetry.io/otel/log` to return a `KeyValue` for an empty value. (#5076)
+- Add `go.opentelemetry.io/otel/log/global` to manage the global `LoggerProvider`.
+  This package is provided with the anticipation that all functionality will be migrate to `go.opentelemetry.io/otel` when `go.opentelemetry.io/otel/log` stabilizes.
+  At which point, users will be required to migrage their code, and this package will be deprecated then removed. (#5085)
+- Add support for `Summary` metrics in the `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp` and `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc` exporters. (#5100)
+- Add `otel.scope.name` and `otel.scope.version` tags to spans exported by `go.opentelemetry.io/otel/exporters/zipkin`. (#5108)
+- Add support for `AddLink` to `go.opentelemetry.io/otel/bridge/opencensus`. (#5116)
+- Add `String` method to `Value` and `KeyValue` in `go.opentelemetry.io/otel/log`. (#5117)
+- Add Exemplar support to `go.opentelemetry.io/otel/exporters/prometheus`. (#5111)
+- Add metric semantic conventions to `go.opentelemetry.io/otel/semconv/v1.24.0`. Future `semconv` packages will include metric semantic conventions as well. (#4528)
+
+### Changed
+
+- `SpanFromContext` and `SpanContextFromContext` in `go.opentelemetry.io/otel/trace` no longer make a heap allocation when the passed context has no span. (#5049)
+- `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc` and `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc` now create a gRPC client in idle mode and with "dns" as the default resolver using [`grpc.NewClient`](https://pkg.go.dev/google.golang.org/grpc#NewClient). (#5151)
+  Because of that `WithDialOption` ignores [`grpc.WithBlock`](https://pkg.go.dev/google.golang.org/grpc#WithBlock), [`grpc.WithTimeout`](https://pkg.go.dev/google.golang.org/grpc#WithTimeout), and [`grpc.WithReturnConnectionError`](https://pkg.go.dev/google.golang.org/grpc#WithReturnConnectionError).
+  Notice that [`grpc.DialContext`](https://pkg.go.dev/google.golang.org/grpc#DialContext) which was used before is now deprecated.
+
+### Fixed
+
+- Clarify the documentation about equivalence guarantees for the `Set` and `Distinct` types in `go.opentelemetry.io/otel/attribute`. (#5027)
+- Prevent default `ErrorHandler` self-delegation. (#5137)
+- Update all dependencies to address [GO-2024-2687]. (#5139)
+
+### Removed
+
+- Drop support for [Go 1.20]. (#4967)
+
+### Deprecated
+
+- Deprecate `go.opentelemetry.io/otel/attribute.Sortable` type. (#4734)
+- Deprecate `go.opentelemetry.io/otel/attribute.NewSetWithSortable` function. (#4734)
