   Changed

   • Replaced interface oteltest.SpanRecorder with its existing implementation StandardSpanRecorder. (#1542)

   • Default span limit values to 128. (#1535)

   • Rename MaxEventsPerSpan, MaxAttributesPerSpan and MaxLinksPerSpan to EventCountLimit, AttributeCountLimit and LinkCountLimit, and move these fields into SpanLimits. (#1535)

   • Renamed the otel/label package to otel/attribute. (#1541)

   • Vendor the Jaeger exporter's dependency on Apache Thrift. (#1551)

   • Parallelize the CI linting and testing. (#1567)

   • Stagger timestamps in exact aggregator tests. (#1569)

   • Changed all examples to use WithBatchTimeout(5 * time.Second) rather than WithBatchTimeout(5). (#1621)

   • Prevent end-users from implementing some interfaces (#1575)

   Removed

   • Removed attempt to resample spans upon changing the span name with span.SetName(). (#1545)
   • The test-benchmark is no longer a dependency of the precommit make target. (#1567)
   • Removed the test-386 make target. This was replaced with a full compatibility testing suite (i.e. multi OS/arch) in the CI system. (#1567)

   Fixed

   • The sequential timing check of timestamps in the stdout exporter are now setup explicitly to be sequential (#1571). (#1572)
   • Windows build of Jaeger tests now compiles with OS specific functions (#1576). (#1577)
   • The sequential timing check of timestamps of go.opentelemetry.io/otel/sdk/metric/aggregator/lastvalue are now setup explicitly to be sequential (#1578). (#1579)
   • Validate tracestate header keys with vendors according to the W3C TraceContext specification (#1475). (#1581)
   • The OTLP exporter includes related labels for translations of a GaugeArray (#1563). (#1570)
