v1.42.0/v0.64.0/v0.18.0/v0.0.16

Added

• Add go.opentelemetry.io/otel/semconv/v1.40.0 package.
  The package contains semantic conventions from the v1.40.0 version of the OpenTelemetry Semantic Conventions.
  See the migration documentation for information on how to upgrade from go.opentelemetry.io/otel/semconv/v1.39.0. (#7985)
• Add Err and SetErr on Record in go.opentelemetry.io/otel/log to attach an error and set record exception attributes in go.opentelemetry.io/otel/log/sdk. (#7924)

Changed

• TracerProvider.ForceFlush in go.opentelemetry.io/otel/sdk/trace joins errors together and continues iteration through SpanProcessors as opposed to returning the first encountered error without attempting exports on subsequent SpanProcessors. (#7856)

Fixed

• Fix missing request.GetBody in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp to correctly handle HTTP2 GOAWAY frame. (#7931)
• Fix semconv v1.39.0 generated metric helpers skipping required attributes when extra attributes were empty. (#7964)
• Preserve W3C TraceFlags bitmask (including the random Trace ID flag) during trace context extraction and injection in go.opentelemetry.io/otel/propagation. (#7834)

Removed

• Drop support for [Go 1.24]. (#7984)

Release v1.40.0/v0.62.0/v0.16.0

Overview

Added

• Add Enabled method to all synchronous instrument interfaces (Float64Counter, Float64UpDownCounter, Float64Histogram, Float64Gauge, Int64Counter, Int64UpDownCounter, Int64Histogram, Int64Gauge,) in go.opentelemetry.io/otel/metric. This stabilizes the synchronous instrument enabled feature, allowing users to check if an instrument will process measurements before performing computationally expensive operations. (#7763)
• Add AlwaysRecord sampler in go.opentelemetry.io/otel/sdk/trace. (#7724)
• Add go.opentelemetry.io/otel/semconv/v1.39.0 package. The package contains semantic conventions from the v1.39.0 version of the OpenTelemetry Semantic Conventions. See the migration documentation for information on how to upgrade from go.opentelemetry.io/otel/semconv/v1.38.0. (#7783, #7789)

Changed

• Exporter in go.opentelemetry.io/otel/exporters/prometheus ignores metrics with the scope go.opentelemetry.io/contrib/bridges/prometheus. This prevents scrape failures when the Prometheus exporter is misconfigured to get data from the Prometheus bridge. (#7688)
• Improve performance of concurrent histogram measurements in go.opentelemetry.io/otel/sdk/metric. (#7474)
• Add experimental observability metrics in go.opentelemetry.io/otel/exporters/stdout/stdoutmetric. (#7492)
• Improve the concurrent performance of HistogramReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar by 4x. (#7443)
• Improve performance of concurrent synchronous gauge measurements in go.opentelemetry.io/otel/sdk/metric. (#7478)
• Improve performance of concurrent exponential histogram measurements in go.opentelemetry.io/otel/sdk/metric. (#7702)
• Improve the concurrent performance of FixedSizeReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar. (#7447)
• The rpc.grpc.status_code attribute in the experimental metrics emitted from go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc is replaced with the rpc.response.status_code attribute to align with the semantic conventions. (#7854)
• The rpc.grpc.status_code attribute in the experimental metrics emitted from go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc is replaced with the rpc.response.status_code attribute to align with the semantic conventions. (#7854)

Fixed

• Fix bad log message when key-value pairs are dropped because of key duplication in go.opentelemetry.io/otel/sdk/log. (#7662)
• Fix DroppedAttributes on Record in go.opentelemetry.io/otel/sdk/log to not count the non-attribute key-value pairs dropped because of key duplication. (#7662)
• Fix SetAttributes on Record in go.opentelemetry.io/otel/sdk/log to not log that attributes are dropped when they are actually not dropped. (#7662)
• WithHostID detector in go.opentelemetry.io/otel/sdk/resource to use full path for ioreg command on Darwin (macOS). (#7818)
• Fix missing request.GetBody in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp to correctly handle HTTP2 GOAWAY frame. (#7794)

Deprecated

• Deprecate go.opentelemetry.io/otel/exporters/zipkin. For more information, see the OTel blog post deprecating the Zipkin exporter. (#7670)

Release v1.39.0/v0.61.0/v0.15.0/v0.0.14

Overview

Added

• Greatly reduce the cost of recording metrics in go.opentelemetry.io/otel/sdk/metric using hashing for map keys. (#7175)
• Add WithInstrumentationAttributeSet option to go.opentelemetry.io/otel/log, go.opentelemetry.io/otel/metric, and go.opentelemetry.io/otel/trace packages. This provides a concurrent-safe and performant alternative to WithInstrumentationAttributes by accepting a pre-constructed attribute.Set. (#7287)
• Add experimental observability for the Prometheus exporter in go.opentelemetry.io/otel/exporters/prometheus. Check the go.opentelemetry.io/otel/exporters/prometheus/internal/x package documentation for more information. (#7345)
• Add experimental observability metrics in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc. (#7353)
• Add temporality selector functions DeltaTemporalitySelector, CumulativeTemporalitySelector, LowMemoryTemporalitySelector to go.opentelemetry.io/otel/sdk/metric. (#7434)
• Add experimental observability metrics for simple log processor in go.opentelemetry.io/otel/sdk/log. (#7548)
• Add experimental observability metrics in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc. (#7459)
• Add experimental observability metrics in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp. (#7486)
• Add experimental observability metrics for simple span processor in go.opentelemetry.io/otel/sdk/trace. (#7374)
• Add experimental observability metrics in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp. (#7512)
• Add experimental observability metrics for manual reader in go.opentelemetry.io/otel/sdk/metric. (#7524)
• Add experimental observability metrics for periodic reader in go.opentelemetry.io/otel/sdk/metric. (#7571)
• Support OTEL_EXPORTER_OTLP_LOGS_INSECURE and OTEL_EXPORTER_OTLP_INSECURE environmental variables in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp. (#7608)
• Add Enabled method to the Processor interface in go.opentelemetry.io/otel/sdk/log. All Processor implementations now include an Enabled method. (#7639)
• The go.opentelemetry.io/otel/semconv/v1.38.0 package. The package contains semantic conventions from the v1.38.0 version of the OpenTelemetry Semantic Conventions. See the migration documentation for information on how to upgrade from go.opentelemetry.io/otel/semconv/v1.37.0.(#7648)

Changed

• Distinct in go.opentelemetry.io/otel/attribute is no longer guaranteed to uniquely identify an attribute set. Collisions between Distinct values for different Sets are possible with extremely high cardinality (billions of series per instrument), but are highly unlikely. (#7175)
• WithInstrumentationAttributes in go.opentelemetry.io/otel/trace synchronously de-duplicates the passed attributes instead of delegating it to the returned TracerOption. (#7266)
• WithInstrumentationAttributes in go.opentelemetry.io/otel/meter synchronously de-duplicates the passed attributes instead of delegating it to the returned MeterOption. (#7266)
• WithInstrumentationAttributes in go.opentelemetry.io/otel/log synchronously de-duplicates the passed attributes instead of delegating it to the returned LoggerOption. (#7266)
• Rename the OTEL_GO_X_SELF_OBSERVABILITY environment variable to OTEL_GO_X_OBSERVABILITY in go.opentelemetry.io/otel/sdk/trace, go.opentelemetry.io/otel/sdk/log, and go.opentelemetry.io/otel/exporters/stdout/stdouttrace. (#7302)
• Improve performance of histogram Record in go.opentelemetry.io/otel/sdk/metric when min and max are disabled using NoMinMax. (#7306)
• Improve error handling for dropped data during translation by using prometheus.NewInvalidMetric in go.opentelemetry.io/otel/exporters/prometheus. ⚠️ Breaking Change: Previously, these cases were only logged and scrapes succeeded. Now, when translation would drop data (e.g., invalid label/value), the exporter emits a NewInvalidMetric, and Prometheus scrapes fail with HTTP 500 by default. To preserve the prior behavior (scrapes succeed while errors are logged), configure your Prometheus HTTP handler with: promhttp.HandlerOpts{ ErrorHandling: promhttp.ContinueOnError }. (#7363)
• Replace fnv hash with xxhash in go.opentelemetry.io/otel/attribute for better performance. (#7371)
• The default TranslationStrategy in go.opentelemetry.io/exporters/prometheus is changed from otlptranslator.NoUTF8EscapingWithSuffixes to otlptranslator.UnderscoreEscapingWithSuffixes. (#7421)
• Improve performance of concurrent measurements in go.opentelemetry.io/otel/sdk/metric. (#7427)
• Include W3C TraceFlags (bits 0–7) in the OTLP Span.Flags field in go.opentelemetry.io/exporters/otlp/otlptrace/otlptracehttp and go.opentelemetry.io/exporters/otlp/otlptrace/otlptracegrpc. (#7438)
• The ErrorType function in go.opentelemetry.io/otel/semconv/v1.37.0 now handles custom error types.
  If an error implements an ErrorType() string method, the return value of that method will be used as the error type. (#7442)

Fixed

• Fix WithInstrumentationAttributes options in go.opentelemetry.io/otel/trace, go.opentelemetry.io/otel/metric, and go.opentelemetry.io/otel/log to properly merge attributes when passed multiple times instead of replacing them. Attributes with duplicate keys will use the last value passed. (#7300)

• Improve performance of BatchProcessor in go.opentelemetry.io/otel/sdk/log by not exporting when exporter cannot accept more. (#6569, #6641)

Deprecated

• Deprecate support for model.LegacyValidation for go.opentelemetry.io/otel/exporters/prometheus. (#6449)

Fixes

• Stop percent encoding header environment variables in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc and go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp. (#6392)
• Ensure the noopSpan.tracerProvider method is not inlined in go.opentelemetry.io/otel/trace so the go.opentelemetry.io/auto instrumentation can instrument non-recording spans. (#6456)
• Use a sync.Pool instead of allocating metricdata.ResourceMetrics in go.opentelemetry.io/otel/exporters/prometheus. (#6472)
