Release Notes

Prelude

In preparation for the upcoming v1.0.0 release, we recommend users enable deprecation warnings after having installed ddtrace>=0.59.0,<1.0.0. See the Upgrading and deprecation warnings section for further details.

New Features

• Add environment variable DD_TRACE_RAISE_DEPRECATIONWARNING to raise library deprecation warnings as errors for those unable to configure warning filters otherwise.
• The profiler now reports asyncio tasks as part as the task field in profiles. This is enabled by default by replacing the default asyncio loop policy. CPU time, wall time and threading lock times are supported.
• Add tracing support for sanic>=21.9.0.

Deprecation Notes

• Tracer.write() is deprecated. Writing spans to the writer through the tracer is not supported.

• ddtrace.constants.NUMERIC_TAGS is deprecated.
• ddtrace.constants.LOG_SPAN_KEY is deprecated.
• Pin.app is deprecated.
• ddtrace.Span.set_meta is deprecated. Use ddtrace.Span.set_tag instead.
• ddtrace.Span.set_metas is deprecated. Use ddtrace.Span.set_tags instead.

• ddtrace.Tracer.log is deprecated. Use ddtrace.tracer.log instead.
