  • Add ErrorType attribute helper function to the go.opentelmetry.io/otel/semconv/v1.34.0 package. (#6962)
  • Add WithAllowKeyDuplication in go.opentelemetry.io/otel/sdk/log which can be used to disable deduplication for log records. (#6968)
  • Add WithCardinalityLimit option to configure the cardinality limit in go.opentelemetry.io/otel/sdk/metric. (#6996, #7065, #7081, #7164, #7165, #7179)
  • Add Clone method to Record in go.opentelemetry.io/otel/log that returns a copy of the record with no shared state. (#7001)
  • Add experimental self-observability span and batch span processor metrics in go.opentelemetry.io/otel/sdk/trace. Check the go.opentelemetry.io/otel/sdk/trace/internal/x package documentation for more information. (#7027, #6393, #7209)
  • The go.opentelemetry.io/otel/semconv/v1.36.0 package. The package contains semantic conventions from the v1.36.0 version of the OpenTelemetry Semantic Conventions. See the migration documentation for information on how to upgrade from go.opentelemetry.io/otel/semconv/v1.34.0.(#7032, #7041)
  • Add support for configuring Prometheus name translation using WithTranslationStrategy option in go.opentelemetry.io/otel/exporters/prometheus.

(#7111)
  • Add experimental self-observability log metrics in go.opentelemetry.io/otel/sdk/log. Check the go.opentelemetry.io/otel/sdk/log/internal/x package documentation for more information. (#7121)
  • Add experimental self-observability trace exporter metrics in go.opentelemetry.io/otel/exporters/stdout/stdouttrace. Check the go.opentelemetry.io/otel/exporters/stdout/stdouttrace/internal/x package documentation for more information. (#7133)
  • Support testing of [Go 1.25]. (#7187)
  • The go.opentelemetry.io/otel/semconv/v1.37.0 package. The package contains semantic conventions from the v1.37.0 version of the OpenTelemetry Semantic Conventions. See the migration documentation for information on how to upgrade from go.opentelemetry.io/otel/semconv/v1.36.0.(#7254)

Changed

  • Optimize TraceIDFromHex and SpanIDFromHex in go.opentelemetry.io/otel/sdk/trace. (#6791)
  • Change AssertEqual in go.opentelemetry.io/otel/log/logtest to accept TestingT in order to support benchmarks and fuzz tests. (#6908)
  • Change DefaultExemplarReservoirProviderSelector in go.opentelemetry.io/otel/sdk/metric to use runtime.GOMAXPROCS(0) instead of runtime.NumCPU() for the FixedSizeReservoirProvider default size. (#7094)

Fixed

  • SetBody method of Record in go.opentelemetry.io/otel/sdk/log now deduplicates key-value collections (log.Value of log.KindMap from go.opentelemetry.io/otel/log). (#7002)
  • Fix go.opentelemetry.io/otel/exporters/prometheus to not append a suffix if it's already present in metric name. (#7088)
  • Fix the go.opentelemetry.io/otel/exporters/stdout/stdouttrace self-observability component type and name. (#7195)
  • Fix partial export count metric in go.opentelemetry.io/otel/exporters/stdout/stdouttrace. (#7199)

Deprecated

  • Deprecate support for OTEL_GO_X_CARDINALITY_LIMIT environment variable in go.opentelemetry.io/otel/sdk/metric. Use WithCardinalityLimit option instead. (#7166)
