Changed

• Upgrade all use of go.opentelemetry.io/otel/semconv to use v1.24.0. (#4754)
• Update transformations in go.opentelemetry.io/otel/exporters/zipkin to follow v1.24.0 version of the OpenTelemetry specification. (#4754)
• Record synchronous measurements when the passed context is canceled instead of dropping in go.opentelemetry.io/otel/sdk/metric.
  If you do not want to make a measurement when the context is cancelled, you need to handle it yourself (e.g if ctx.Err() != nil). (#4671)
• Improve go.opentelemetry.io/otel/trace.TraceState's performance. (#4722)
• Improve go.opentelemetry.io/otel/propagation.TraceContext's performance. (#4721)
• Improve go.opentelemetry.io/otel/baggage performance. (#4743)
• Improve performance of the (*Set).Filter method in go.opentelemetry.io/otel/attribute when the passed filter does not filter out any attributes from the set. (#4774)
• Member.String in go.opentelemetry.io/otel/baggage percent-encodes only when necessary. (#4775)
• Property.Value in go.opentelemetry.io/otel/baggage now returns a raw string instead of a percent-encoded value. (#4804)

Fixed

• Fix Parse in go.opentelemetry.io/otel/baggage to validate member value before percent-decoding. (#4755)
• Fix whitespace encoding of Member.String in go.opentelemetry.io/otel/baggage. (#4756)
• Fix baggage item key so that it is not canonicalized in go.opentelemetry.io/otel/bridge/opentracing. (#4776)
• Fix go.opentelemetry.io/otel/bridge/opentracing to properly handle baggage values that requires escaping during propagation. (#4804)
• Fix a bug where using multiple readers resulted in incorrect asynchronous counter values in go.opentelemetry.io/otel/sdk/metric. (#4742)
