go.opentelemetry.io/otel/sdk

This release is the last to support [Go 1.22]. The next release will require at least [Go 1.23].

Added

• Add ValueFromAttribute and KeyValueFromAttribute in go.opentelemetry.io/otel/log. (#6180)
• Add EventName and SetEventName to Record in go.opentelemetry.io/otel/log. (#6187)
• Add EventName to RecordFactory in go.opentelemetry.io/otel/log/logtest. (#6187)
• AssertRecordEqual in go.opentelemetry.io/otel/log/logtest checks Record.EventName. (#6187)
• Add EventName and SetEventName to Record in go.opentelemetry.io/otel/sdk/log. (#6193)
• Add EventName to RecordFactory in go.opentelemetry.io/otel/sdk/log/logtest. (#6193)
• Emit Record.EventName field in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc. (#6211)
• Emit Record.EventName field in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp. (#6211)
• Emit Record.EventName field in go.opentelemetry.io/otel/exporters/stdout/stdoutlog (#6210)
• The go.opentelemetry.io/otel/semconv/v1.28.0 package. The package contains semantic conventions from the v1.28.0 version of the OpenTelemetry Semantic Conventions. See the migration documentation for information on how to upgrade from go.opentelemetry.io/otel/semconv/v1.27.0(#6236)
• The go.opentelemetry.io/otel/semconv/v1.30.0 package. The package contains semantic conventions from the v1.30.0 version of the OpenTelemetry Semantic Conventions. See the migration documentation for information on how to upgrade from go.opentelemetry.io/otel/semconv/v1.28.0(#6240)
• Document the pitfalls of using Resource as a comparable type. Resource.Equal and Resource.Equivalent should be used instead. (#6272)
• Support [Go 1.24]. (#6304)
• Add FilterProcessor and EnabledParameters in go.opentelemetry.io/otel/sdk/log. It replaces go.opentelemetry.io/otel/sdk/log/internal/x.FilterProcessor. Compared to previous version it additionally gives the possibility to filter by resource and instrumentation scope. (#6317)

Changed

• Update github.com/prometheus/common to v0.62.0, which changes the NameValidationScheme to NoEscaping. This allows metrics names to keep original delimiters (e.g. .), rather than replacing with underscores. This is controlled by the Content-Type header, or can be reverted by setting NameValidationScheme to LegacyValidation in github.com/prometheus/common/model. (#6198)

Fixes

• Eliminate goroutine leak for the processor returned by NewSimpleSpanProcessor in go.opentelemetry.io/otel/sdk/trace when Shutdown is called and the passed ctx is canceled and SpanExporter.Shutdown has not returned. (#6368)
• Eliminate goroutine leak for the processor returned by NewBatchSpanProcessor in go.opentelemetry.io/otel/sdk/trace when ForceFlush is called and the passed ctx is canceled and SpanExporter.Export has not returned. (#6369)
