Added

• Add example for go.opentelemetry.io/otel/exporters/stdout/stdoutlog. (#5242)
• Add RecordFactory in go.opentelemetry.io/otel/sdk/log/logtest to facilitate testing exporter and processor implementations. (#5258)
• Add RecordFactory in go.opentelemetry.io/otel/log/logtest to facilitate testing bridge implementations. (#5263)
• The count of dropped records from the BatchProcessor in go.opentelemetry.io/otel/sdk/log is logged. (#5276)
• Add metrics in the otel-collector example. (#5283)
• Add the synchronous gauge instrument to go.opentelemetry.io/otel/metric. (#5304)
  • An int64 or float64 synchronous gauge instrument can now be created from a Meter.
  • All implementations of the API (go.opentelemetry.io/otel/metric/noop, go.opentelemetry.io/otel/sdk/metric) are updated to support this instrument.
• Add logs to go.opentelemetry.io/otel/example/dice. (#5349)

Changed

• The Shutdown method of Exporter in go.opentelemetry.io/otel/exporters/stdout/stdouttrace ignores the context cancellation and always returns nil. (#5189)
• The ForceFlush and Shutdown methods of the exporter returned by New in go.opentelemetry.io/otel/exporters/stdout/stdoutmetric ignore the context cancellation and always return nil. (#5189)
• Apply the value length limits to Record attributes in go.opentelemetry.io/otel/sdk/log. (#5230)
• De-duplicate map attributes added to a Record in go.opentelemetry.io/otel/sdk/log. (#5230)

• The go.opentelemetry.io/otel/exporters/stdout/stdoutlog exporter won't print AttributeValueLengthLimit and AttributeCountLimit fields now, instead it prints the DroppedAttributes field. (#5272)
• Improved performance in the Stringer implementation of go.opentelemetry.io/otel/baggage.Member by reducing the number of allocations. (#5286)

• Fix the empty output of go.opentelemetry.io/otel/log.Value in go.opentelemetry.io/otel/exporters/stdout/stdoutlog. (#5311)
• Split the behavior of Recorder in go.opentelemetry.io/otel/log/logtest so it behaves as a LoggerProvider only. (#5365)
• Fix wrong package name of the error message when parsing endpoint URL in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp. (#5371)
• Identify the Logger returned from the global LoggerProvider in go.opentelemetry.io/otel/log/global with its schema URL. (#5375)

[1.26.0/0.48.0/0.2.0-alpha] 2024-04-24
