Releases v1.28.0/v0.50.0/v0.4.0

Overview

Added

• The IsEmpty method is added to the Instrument type in go.opentelemetry.io/otel/sdk/metric.
  This method is used to check if an Instrument instance is a zero-value. (#5431)
• Store and provide the emitted context.Context in ScopeRecords of go.opentelemetry.io/otel/sdk/log/logtest. (#5468)
• The go.opentelemetry.io/otel/semconv/v1.26.0 package.
  The package contains semantic conventions from the v1.26.0 version of the OpenTelemetry Semantic Conventions. (#5476)
• The AssertRecordEqual method to go.opentelemetry.io/otel/log/logtest to allow comparison of two log records in tests. (#5499)
• The WithHeaders option to go.opentelemetry.io/otel/exporters/zipkin to allow configuring custom http headers while exporting spans. (#5530)

Changed

• Tracer.Start in go.opentelemetry.io/otel/trace/noop no longer allocates a span for empty span context. (#5457)
• Upgrade go.opentelemetry.io/otel/semconv/v1.25.0 to go.opentelemetry.io/otel/semconv/v1.26.0 in go.opentelemetry.io/otel/example/otel-collector. (#5490)
• Upgrade go.opentelemetry.io/otel/semconv/v1.25.0 to go.opentelemetry.io/otel/semconv/v1.26.0 in go.opentelemetry.io/otel/example/zipkin. (#5490)
• Upgrade go.opentelemetry.io/otel/semconv/v1.25.0 to go.opentelemetry.io/otel/semconv/v1.26.0 in go.opentelemetry.io/otel/exporters/zipkin. (#5490)
  • The exporter no longer exports the deprecated "otel.library.name" or "otel.library.version" attributes.
• Upgrade go.opentelemetry.io/otel/semconv/v1.25.0 to go.opentelemetry.io/otel/semconv/v1.26.0 in go.opentelemetry.io/otel/sdk/resource. (#5490)
• Upgrade go.opentelemetry.io/otel/semconv/v1.25.0 to go.opentelemetry.io/otel/semconv/v1.26.0 in go.opentelemetry.io/otel/sdk/trace. (#5490)
• SimpleProcessor.OnEmit in go.opentelemetry.io/otel/sdk/log no longer allocates a slice which makes it possible to have a zero-allocation log processing using SimpleProcessor. (#5493)
• Use non-generic functions in the Start method of "go.opentelemetry.io/otel/sdk/trace".Trace to reduce memory allocation. (#5497)
• service.instance.id is populated for a Resource created with "go.opentelemetry.io/otel/sdk/resource".Default with a default value when OTEL_GO_X_RESOURCE is set. (#5520)
• Improve performance of metric instruments in go.opentelemetry.io/otel/sdk/metric by removing unnecessary calls to time.Now. (#5545)

Fixed

• Log a warning to the OpenTelemetry internal logger when a Record in go.opentelemetry.io/otel/sdk/log drops an attribute due to a limit being reached. (#5376)
• Identify the Tracer returned from the global TracerProvider in go.opentelemetry.io/otel/global with its schema URL. (#5426)
• Identify the Meter returned from the global MeterProvider in go.opentelemetry.io/otel/global with its schema URL. (#5426)
• Log a warning to the OpenTelemetry internal logger when a Span in go.opentelemetry.io/otel/sdk/trace drops an attribute, event, or link due to a limit being reached. (#5434)
• Document instrument name requirements in go.opentelemetry.io/otel/metric. (#5435)
• Prevent random number generation data-race for experimental rand exemplars in go.opentelemetry.io/otel/sdk/metric. (#5456)
• Fix counting number of dropped attributes of Record in go.opentelemetry.io/otel/sdk/log. (#5464)
• Fix panic in baggage creation when a member contains 0x80 char in key or value. (#5494)
• Correct comments for the priority of the WithEndpoint and WithEndpointURL options and their corresponding environment variables in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc. (#5508)
• Retry trace and span ID generation if it generated an invalid one in go.opentelemetry.io/otel/sdk/trace. (#5514)
• Fix stale timestamps reported by the last-value aggregation. (#5517)
• Indicate the Exporter in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp must be created by the New method. (#5521)
• Improved performance in all {Bool,Int64,Float64,String}SliceValue functions of go.opentelemetry.io/attributes by reducing the number of allocations. (#5549)
