Release Notes

open-telemetry/opentelemetry-go (go.opentelemetry.io/otel/sdk/log)

v0.4.0

Compare Source

Added

• New API package api/metric/registry that exposes a MeterImpl wrapper for use by SDKs to generate unique instruments. (#​580)
• Script to verify examples after a new release. (#​579)

Removed

• The dogstatsd exporter due to lack of support.
  This additionally removes support for statsd. (#​591)
• LabelSet from the metric API.
  This is replaced by a []core.KeyValue slice. (#​595)
• Labels from the metric API's Meter interface. (#​595)

Changed

• The metric export.Labels became an interface which the SDK implements and the export package provides a simple, immutable implementation of this interface intended for testing purposes. (#​574)
• Renamed internal/metric.Meter to MeterImpl. (#​580)
• Renamed api/global/internal.obsImpl to asyncImpl. (#​580)

Fixed

• Corrected missing return in mock span. (#​582)
• Update License header for all source files to match CNCF guidelines and include a test to ensure it is present. (#​586) (#​596)

• Moved span transforms of the OTLP exporter to the internal package. (#​593)
• Build both go-1.13 and go-1.14 in circleci to test for all supported versions of Go. (#​569)
• Removed unneeded allocation on empty labels in OLTP exporter. (#​597)
• Update BatchedSpanProcessor to process the queue until no data but respect max batch size. (#​599)
