Python 3.12 Now Under Feature Freeze With Beta 1 Released

The first beta release of Python 3.12 is now available that also marks the beginning of the feature freeze for this year's major Python update.

Python 3.12 has prepared a new type annotation syntax for generic classes, more flexible F-string parsing, improved error messages, continued mix of performance improvements, support for the Linux perf profiler, removing various deprecated functions, and much more. More details on all of the changes to expect with Python 3.12 can be found via docs.python.org.
