Python 3.12.5 is now available:

https://www.python.org/downloads/release/python-3125/

This is the fifth 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. 3.12.5 is the latest maintenance release, containing more than 250 bugfixes, build improvements
and documentation changes since 3.12.4.

This version of Python 3.12 also comes with pip 24.2 by default. *However,
due to an incompatibility with older macOS versions, macOS 10.9 through
10.12 will downgrade their version of pip to 24.1.2 during the installation process* (in the Install Certificates step). See the installer ReadMe and the pip issue on the matter <https://github.com/pypa/pip/issues/12901> for more information. Versions of macOS older than 10.13 haven’t been supported by Apple since 2019, and maintaining support for them is becoming increasingly difficult. While this release of 3.12 still supports them, *it is likely
that we will be forced to drop support for macOS 10.12 and older in a
future 3.12 release*. (Python 3.13 has already dropped support for them.) <https://discuss.python.org/t/python-3-12-5-now-available/60219#p-182613-major-new-features-of-the-312-series-compared-to-311-2>Major
new features of the 3.12 series, compared to 3.11 <https://discuss.python.org/t/python-3-12-5-now-available/60219#p-182613-new-features-3>New
features

- More flexible f-string parsing
<https://docs.python.org/3.12/whatsnew/3.12.html#pep-701-syntactic-formalization-of-f-strings>,
allowing many things previously disallowed (PEP 701
<https://peps.python.org/pep-0701/>).
- Support for the buffer protocol
<https://docs.python.org/3.12/whatsnew/3.12.html#pep-688-making-the-buffer-protocol-accessible-in-python>
in Python code (PEP 688 <https://peps.python.org/pep-0688/>).
- A new debugging/profiling API
<https://docs.python.org/3.12/whatsnew/3.12.html#pep-669-low-impact-monitoring-for-cpython>
(PEP 669 <https://peps.python.org/pep-0669/>).
- Support for isolated subinterpreters
<https://docs.python.org/3.12/whatsnew/3.12.html#pep-684-a-per-interpreter-gil>
with separate Global Interpreter Locks (PEP 684
<https://peps.python.org/pep-0684>).
- Even more improved error messages
<https://docs.python.org/3.12/whatsnew/3.12.html#improved-error-messages>.
More exceptions potentially caused by typos now make suggestions to the
user.
- Support for the Linux perf profiler
<https://docs.python.org/3.12/howto/perf_profiling.html> to report
Python function names in traces.
- Many large and small performance improvements
<https://docs.python.org/3.12/whatsnew/3.12.html#optimizations> (like PEP
709 <https://peps.python.org/pep-0709/> and support for the BOLT binary
optimizer), delivering an estimated 5% overall performance improvement.

<https://discuss.python.org/t/python-3-12-5-now-available/60219#p-182613-type-annotations-4>Type
annotations

- New type annotation syntax
<https://docs.python.org/3.12/whatsnew/3.12.html#pep-695-type-parameter-syntax>
for generic classes (PEP 695 <https://peps.python.org/pep-0695/>).
- New override decorator
<https://docs.python.org/3.12/whatsnew/3.12.html#pep-698-override-decorator-for-static-typing>
for methods (PEP 698 <https://peps.python.org/pep-0698>).

<https://discuss.python.org/t/python-3-12-5-now-available/60219#p-182613-deprecations-5>
Deprecations

- The deprecated wstr and wstr_length members of the C implementation of
unicode objects were removed, per PEP 623
<https://peps.python.org/pep-0623/>.
- 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 <https://peps.python.org/pep-0594/> and PEP 632
<https://peps.python.org/pep-0632/>. The setuptools package continues to
provide the distutils module.
- A number of other old, broken and deprecated functions, classes and
methods <https://docs.python.org/3.12/whatsnew/3.12.html#removed> 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.)
