Added

  • The go.opentelemetry.io/otel/semconv/v1.22.0 package. The package contains semantic conventions from the v1.22.0 version of the OpenTelemetry Semantic Conventions. (#4735)
  • The go.opentelemetry.io/otel/semconv/v1.23.0 package. The package contains semantic conventions from the v1.23.0 version of the OpenTelemetry Semantic Conventions. (#4746)
  • The go.opentelemetry.io/otel/semconv/v1.23.1 package. The package contains semantic conventions from the v1.23.1 version of the OpenTelemetry Semantic Conventions. (#4749)
  • The go.opentelemetry.io/otel/semconv/v1.24.0 package. The package contains semantic conventions from the v1.24.0 version of the OpenTelemetry Semantic Conventions. (#4770)
  • Add WithResourceAsConstantLabels option to apply resource attributes for every metric emitted by the Prometheus exporter. (#4733)
  • Experimental cardinality limiting is added to the metric SDK. See metric documentation for more information about this feature and how to enable it. (#4457)
  • Add NewMemberRaw and NewKeyValuePropertyRaw in go.opentelemetry.io/otel/baggage. (#4804)

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)
