I'm pleased to announce the release of Python 3.12.7:

https://www.python.org/downloads/release/python-3127/

 

This is the seventh maintenance release of Python 3.12

Python 3.12 is the newest major release of the Python programming language, and it contains many new features and optimizations. 3.12.7 is the latest maintenance release, containing more than 100 bugfixes, build improvements and documentation changes since 3.12.6.

 

Major new features of the 3.12 series, compared to 3.11

Deprecations

  • The deprecated wstr and wstr_length members of the C implementation of unicode objects were removed, per PEP 623.
  • In the unittest module, a number of long deprecated methods and classes were removed. (They had been deprecated since Python 3.1 or 3.2).
  • The deprecated smtpd and distutils modules have been removed (see PEP 594 and PEP 632. The setuptools package continues to provide the distutils module.
  • A number of other old, broken and deprecated functions, classes and methods have been removed.
  • Invalid backslash escape sequences in strings now warn with SyntaxWarning instead of DeprecationWarning, making them more visible. (They will become syntax errors in the future.)
  • The internal representation of integers has changed in preparation for performance enhancements. (This should not affect most users as it is an internal detail, but it may cause problems for Cython-generated code.)
