- Fix type hints for the logging integration. Thanks Steven Dignam!
- Fix an issue where scope/context data would leak in applications that use `gevent` with its threading monkeypatch. The fix is to avoid usage of contextvars in such environments. Thanks Ran Benita!
- Fix a reference cycle in the `ThreadingIntegration` that led to exceptions on interpreter shutdown. Thanks Guang Tian Li!
- Fix a series of bugs in the stdlib integration that broke usage of `subprocess`.
- More instrumentation for APM.
- New integration for SQLAlchemy (creates breadcrumbs from queries).
- New (experimental) integration for Apache Beam.
- Fix a bug in the `LoggingIntegration` that would send breadcrumbs timestamps in the wrong timezone.
- The `AiohttpIntegration` now sets the event's transaction name.
- Fix a bug that caused infinite recursion when serializing local variables that logged errors or otherwise created Sentry events.
