 The next release will require at least [Go 1.22].
 
 ### Added
 
-- Add macOS ARM64 platform to the compatibility testing suite. (#5577)
+- Add MacOS ARM64 platform to the compatibility testing suite. (#5577)
+- Add `InstrumentationScope` field to `SpanStub` in `go.opentelemetry.io/otel/sdk/trace/tracetest`, as a replacement for the deprecated `InstrumentationLibrary`. (#5627)
 - Make the initial release of `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`.
   This new module contains an OTLP exporter that transmits log telemetry using gRPC.
   This module is unstable and breaking changes may be introduced.
   See our [versioning policy](VERSIONING.md) for more information about these stability guarantees. (#5629)
-- Add `InstrumentationScope` field to `SpanStub` in `go.opentelemetry.io/otel/sdk/trace/tracetest`, as a replacement for the deprecated `InstrumentationLibrary`. (#5627)
-- Zero value of `SimpleProcessor` in `go.opentelemetry.io/otel/sdk/log` no longer panics. (#5665)
 - Add `Walk` function to `TraceState` in `go.opentelemetry.io/otel/trace` to iterate all the key-value pairs. (#5651)
 - Bridge the trace state in `go.opentelemetry.io/otel/bridge/opencensus`. (#5651)
+- Zero value of `SimpleProcessor` in `go.opentelemetry.io/otel/sdk/log` no longer panics. (#5665)
 - The `FilterProcessor` interface type is added in `go.opentelemetry.io/otel/sdk/log/internal/x`.
   This is an optional and experimental interface that log `Processor`s can implement to instruct the `Logger` if a `Record` will be processed or not.
   It replaces the existing `Enabled` method that is removed from the `Processor` interface itself.

 ### Changed
 
+- `NewMemberRaw`, `NewKeyProperty` and `NewKeyValuePropertyRaw` in `go.opentelemetry.io/otel/baggage` allow UTF-8 string in key. (#5132)
 - `Processor.OnEmit` in `go.opentelemetry.io/otel/sdk/log` now accepts a pointer to `Record` instead of a value so that the record modifications done in a processor are propagated to subsequent registered processors. (#5636)
 - `SimpleProcessor.Enabled` in `go.opentelemetry.io/otel/sdk/log` now returns `false` if the exporter is `nil`. (#5665)
 - Update the concurrency requirements of `Exporter` in `go.opentelemetry.io/otel/sdk/log`. (#5666)
