Python 3.12.0 beta 4 released

Posted on by Michael G

 I’m pleased to announce the release of Python 3.12 beta 4.

https://www.python.org/downloads/release/python-3120b4/

This is a beta preview of Python 3.12

Python 3.12 is still in development. This release, 3.12.0b4, is the final of four beta release previews of 3.12.

Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release.

We strongly encourage maintainers of third-party Python projects to test with 3.12 during the beta phase and report issues found to [the Python bug tracker (https://github.com/python/cpython/issues) as soon as possible. While the release is planned to be feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (Monday, 2023-07-31). Our goal is to have no ABI changes after this release, and as few code changes as possible after 3.12.0rc1, the first release candidate. To achieve that, it will be extremely important to get as much exposure for 3.12 as possible during the beta phase.

Please keep in mind that this is a preview release and its use is not recommended for production environments.

Major new features of the 3.12 series, compared to 3.11

Some of the new major new features and changes in Python 3.12 are:

  • New type annotation syntax for generic classes (PEP 695).
  • More flexible f-string parsing, allowing many things previously disallowed (PEP 701).
  • Support for the buffer protocol in Python code (PEP 688).
  • Even more improved error messages. More exceptions potentially caused by typos now make suggestions to the user.
  • Many large and small performance improvements (like PEP 709).
  • Support for the Linux perf profiler to report Python function names in traces.
  • 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.)
  • (Hey, fellow core developer, if a feature you find important is missing from this list, let Thomas know.)

For more details on the changes to Python 3.12, see What’s new in Python 3.12. The next pre-release of Python 3.12 will be 3.12.0rc1, the first release candidate, currently scheduled for 2023-07-31.

Wayland on OpenBSD

Posted on by Michael G

Matthieu Herrb (matthieu@) has written some notes
on his work at the (recently-concluded)
g2k23 hackathon
in Tallinn, Estonia.
His article,
Wayland on OpenBSD,
starts:

These are my notes from experimenting with building Wayland bits on OpenBSD during g2k23 in Tallinn… Thanks to the OpenBSD foundation for organizing this event.

This is still far from a complete running system as there are many issues on the road, but it’s a good start and it shows that it’s definatly not impossible to get Wayland running on OpenBSD.

Suse will Fork RHEL

Posted on by Michael G
Today SUSE, the company behind Rancher, NeuVector, and SUSE Linux Enterprise (SLE) and a global leader in enterprise open source solutions, announced it is forking publicly available Red Hat Enterprise Linux (RHEL) and will develop and maintain a RHEL-compatible distribution available to all without restrictions. Over the next few years, SUSE plans to invest more than $10 million into this project.   The spicy bit here is that the CEO of SUSE, Dirk-Peter van Leeuwen, worked at Red Hat for 18 years before joining SUSE. Excellent.
