Python 3.10.2, 3.9.10, and 3.11.0a4 released: interpreted high-level programming language

Python is an interpreted high-level programming language for general-purpose programming. Created by Guido van Rossum and first released in 1991, Python has a design philosophy that emphasizes code readability, notably using significant whitespace. It provides constructs that enable clear programming on both small and large scales.

Python features a dynamic type system and automatic memory management. It supports multiple programming paradigms, including object-oriented, imperative, functional and procedural, and has a large and comprehensive standard library.

Python interpreters are available for many operating systems. CPython, the reference implementation of Python, is open source software and has a community-based development model, as do nearly all of its variant implementations. CPython is managed by the non-profit Python Software Foundation. via_Wiki

Python 3.10.2, 3.9.10, and 3.11.0a4 are now available.


Python 3.10.2

Get it here:

This is a special bugfix release ahead of schedule to address a memory leak that was happening on certain function calls when using Cython. The memory leak consisted of a small constant amount of bytes in certain function calls from Cython code. Although in most cases this was not very noticeable, it was very impactful for long-running applications and certain usage patterns. Check bpo-46347 for more information.

Upgrading existing Python 3.10 installations is highly recommended. Even though this is an expedited release, it still contains over 100 other bug fixes. See the change log for details.

The next Python 3.10 maintenance release will be 3.10.3, currently scheduled for 2022-04-04.

Python 3.9.10

Get it here:

Python 3.9.10 is the ninth maintenance release of the legacy 3.9 series. Note: Python 3.10 is now the latest feature release series of Python 3.

Python 3.9 micro-releases enter double digits! There’s been 130 commits since 3.9.9 which is a higher number of fixes for this stage of the life cycle compared to 3.8. See the changelog for details on what changed.

As a reminder, on macOS, the default installer is now the new universal2 variant. It’s compatible with Mac OS X 10.9 and newer, including macOS 11 Big Sur and macOS 12 Monterey. Python installed with this variant will work natively on Apple Silicon processors.

The next Python 3.9 maintenance release will be 3.9.11, currently scheduled for Pi Day ’22 (2022-03-14).

Python 3.11.0a4

Get it here:

Python 3.11 is still in development. This release, 3.11.0a4, is the fourth of seven planned alpha releases.

Alpha releases are intended to make it easier to test the current state of new features and bug fixes by the community, as well as to test the release process.

During the alpha phase, features may be added up until the start of the beta phase (2022-05-06) and, if necessary, may be modified or deleted up until the release candidate phase (2022-08-01). Please keep in mind that this is a preview release and its use is not recommended for production environments.

Many new features for Python 3.11 are still being planned and written. Among the new major new features and changes so far:

  • PEP 657 – Include Fine-Grained Error Locations in Tracebacks
  • PEP 654 – Exception Groups and except*
  • The Faster CPython Project is already yielding some exciting results: this version of CPython 3.11 is ~ 19% faster on the geometric mean of the PyPerformance benchmarks, compared to 3.10.0.
