Release Notes

v0.60.0

Prelude

In preparation for the upcoming v1.0.0 release, we recommend users enable deprecation warnings after having installed ddtrace>=0.60.0,<1.0.0. See the Upgrading and deprecation warnings section for further details.

New Features

• asyncpg: add integration supporting v0.18.0 and above. See the docs for more information.

• Add environment variable DD_TRACE_RAISE_DEPRECATIONWARNING to raise library deprecation warnings as errors for those unable to configure warning filters otherwise.

• Add Span.get_tags and Span.get_metrics.

• aiohttp: add client integration. This integration traces requests made using the aiohttp client and includes support for distributed tracing. See the documentation for more information.

• aiohttp_jinja2: move into new integration. Formerly the aiohttp_jinja2 instrumentation was enabled using the aiohttp integration. Use patch(aiohttp_jinja2=True) instead of patch(aiohttp=True). To support legacy behavior patch(aiohttp=True) will still enable aiohttp_jinja2.

• fastapi: add support for tracing fastapi.routing.serialize_response.
  This will give an insight into how much time is spent calling jsonable_encoder within a given request. This does not provide visibility into how long it takes for Response.render/json.dumps.

Deprecation Notes

• Span.to_dict is deprecated and will be removed in v1.0.0.
• ddtrace.Tracer.log is deprecated. Use logging.getLogger("ddtrace.tracer") instead.
• Tracer.write() is deprecated. Writing spans to the writer through the tracer is not supported.

Bug Fixes

• botocore: fix incorrect context propagation message attribute types for SNS. This addresses Datadog/serverless-plugin-datadog#232
• aiohttp: fix issue causing ddtrace.contrib.aiohttp_jinja2.patch module to be imported instead of the patch() function.
• Remove Pin.app deprecation warning from celery instrumentation.
• tracing/internal: fix encoding of propagated internal tags.
• Fix issue building ddtrace from source on macOS 12.
• Fixes wrong numbers of memory allocation being reported in the memory profiler.
• pymongo: fix write_command being patched with the wrong method signature.

Other Notes

• tracing/internal: disable Datadog internal tag propagation
