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

 

New features

• More flexible f-string parsing, allowing many things previously disallowed (PEP 701).
• Support for the buffer protocol in Python code (PEP 688).
• A new debugging/profiling API (PEP 669).
• Support for isolated subinterpreters with separate Global Interpreter Locks (PEP 684).
• Even more improved error messages. More exceptions potentially caused by typos now make suggestions to the user.
• Support for the Linux perf profiler to report Python function names in traces.
• Many large and small performance improvements (like PEP 709 and support for the BOLT binary optimizer), delivering an estimated 5% overall performance improvement.

Type annotations

• New type annotation syntax for generic classes (PEP 695).
• New override decorator for methods (PEP 698).

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.)

Join the FSF and friends on Friday, October 4 from 12:00 to 15:00 EDT (16:00 to 19:00 UTC) to help improve the Free Software Directory.

A few weeks ago I attended Open Source Summit Europe 2024, an event organized by the Linux Foundation, that brought together brilliant developers, technologists and leaders from all over the world, reinforcing what Open Source is truly about—collaboration, innovation and community.

FreeBSD is going to take its desktop use quite a bit more seriously going forward. FreeBSD has long been a top choice for IT professionals and organizations focused on servers and networking, and it is known for its unmatched stability, performance, and security. However, as technology evolves, FreeBSD faces a significant challenge: supporting modern laptops. To address this, the FreeBSD Foundation and Quantum Leap Research has committed $750,000 to improve laptop support, a strategic investment that will be pivotal in FreeBSD’s future. ↫ FreeBSD Foundation blog So, what are they going to spend this big bag of money on? Well, exactly the kind of things you expect. They want to improve and broaden support for various wireless chipsets, add support for modern powersaving processor states, and make sure laptop-specific features like touchpad gestures, specialty buttons, and so on, work properly. On top of that, they want to invest in better graphics driver support for Intel and AMD, as well as make it more seamless to switch between various audio devices, which is especially crucial on laptops where people might reasonably be expected to use headphones. In addition, while not specifically related to laptops, FreeBSD also intends to invest in support for heterogeneous cores in its scheduler and improvements to the bhyve hypervisor. Virtualisation is, of course, not just something for large desktops and servers, but also laptop users might turn to for certain tasks and workloads. The FreeBSD project will be working not just with Quantum Leap Research, but also various hardware makers to assist in bringing FreeBSD’s laptop support to a more modern, plug-and-play state. Additionally, the mentioned cash injection is not set in stone; additional contributions from both individuals and larger organisations are obviously welcome, and of course if you can contribute code, bug reports, documentation, and so on, you’re also more than welcome to jump in.
