Full Changelog: 1.1.4...1.1.5

1.1.4

General

• Some of the tests should be less flaky now #304, #305

Spans

• Fix race condition when creating a new tracer, it could crash when creating multiple tracers concurrently #306

SDKResourceExtension

• DeviceDataSource model on mac was not working properly #298

1.1.3

OpenTelemetryProtocol (OTLP) Exporter

• update OTLP Exporter and proto files to match the changes in the metrics specifications. It now needs a collector version >= 0.50.0 #301

Persistence Exporter

• Simplified configuration of Persistence exporter and reduced number of used queues #288

OTLP Exporter Sample

• Improved documentation about setting service name #303

1.1.2

General

• OpenTelemetryContextProvider now works correctly for activeSpan and activeBaggage when using Concurrency framework and async/await code. Limited to using XCode 13.2 and up, any version lower than that can fail when using new Concurrency features.

Datadog Exporter

• Add us5 to list of possible endpoints

1.1.1

General

• Improve SemanticConvention generation template #277

Traces

• Make SpanData conform to Codable to support persisting #279
• Fix startTime for spans, it was always using the SpanBuilder creation time as the start time #282

Metrics

• Make Metric conform to Codable to support persisting #279

Resources

• Added extra parameters to resource attributes, as per the updated spec #276
• Fixed bug where enum values were not public, and thus could not be used by clients #276

New Persistence Exporter

• The Persistence Exporter is not an actual exporter by itself, but an exporter decorator. It decorates a given exporter by persisting the exported data to the disk first, and then proceeds to forward it to the decorated exporter. More information and examples in the included README. #280

1.1.0

Package

• Removed duplicated lib products, use non lib prefixed ones. Since 1.0.3 they have been exactly equal. #271 (Breaking)

General

• Provide a way to register the different propagators other than W3C. #261
• Add a Zipkin baggage propagator #264
• Update SemanticAttributes and ResourceAttributes to version 1.7.0 #272 (Breaking)

Traces

• Removed textFormat member from TracerSdk, users of this propagators must use the global registered ones instead: OpenTelemetry.instance.propagators.textMapPropagator #261 (Breaking)
• SimpleSpanProcessor now exports the spans asynchronously, and synchronises only on shutdown or flush. For production environments BatchSpanProcessor is still preferred. #263
• Implement ForceFlush spec on Span processors adding a timeout parameter. #273

Resources

• Fix environment variable for specifying resource attribute as it was not following the spec. Changed to OTEL_RESOURCE_ATTRIBUTES from OTEL_RESOURCE_ATTRIBUTES_ENV #255 (Breaking)
