OpenTelemetry - CNCF/opentelemetry-erlang: Release v0.5.0

Name: opentelemetry-erlang

Owner: OpenTelemetry - CNCF

Release: v0.5.0 for API, SDK and OTLP Exporter

Released: 2020-11-20

License: Apache-2.0

Release Assets:

Major change in this release is we now match the spec for start_span, meaning it no longer sets the started Span to the current Span in the Context. To start a Span and set it to the current Span use with_span or pass the return value of start_span to set_current_span.

Some PR links are missing because they were made before the repos were combined.
