Python 3.14.0 alpha 4 is out
by Hugo van Kemenade Jan. 14, 2025

Jan. 14, 2025

Hello, three dot fourteen dot zero alpha four! https://www.python.org/downloads/release/python-3140a4/ This is an early developer preview of Python 3.14. Python 3.14 is still in development. This release, 3.14.0a4, 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 and to test the release process. During the alpha phase, features may be added up until the start of the beta phase (2025-05-06) and, if necessary, may be modified or deleted up until the release candidate phase (2025-07-22). Please keep in mind that this is a preview release and its use is not recommended for production environments. Many new features for Python 3.14 are still being planned and written. Among the new major new features and changes so far: * PEP 649: deferred evaluation of annotations * PEP 741: Python configuration C API * PEP 761: Python 3.14 and onwards no longer provides PGP signatures for release artifacts. Instead, Sigstore is recommended for verifiers. * Improved error messages * Removals of old deprecations, and new deprecations, many scheduled for removal from Python 3.16 * C API removals and deprecations * (Hey, fellow core developer, if a feature you find important is missing from this list, let Hugo know.) The next pre-release of Python 3.14 will be 3.14.0a5, currently scheduled for 2025-02-11. More resources: * Online documentation: https://docs.python.org/3.14/ * PEP 745, 3.14 Release Schedule: https://peps.python.org/pep-0745/ * Report bugs at https://github.com/python/cpython/issues * Help fund Python and its community: https://www.python.org/psf/donations/ And now for something completely different In Python, you can use Greek letters as constants. For example: ``` from math import pi as π def circumference(radius: float) -> float: return 2 * π * radius print(circumference(6378.137)) # 40075.016685578485 ``` Enjoy the new release. Thanks to all of the many volunteers who help make Python Development and these releases possible! Please consider supporting our efforts by volunteering yourself or through organisation contributions to the Python Software Foundation. Regards from a slushy, slippery Helsinki, Your release team, Hugo van Kemenade Ned Deily Steve Dower Łukasz Langa

RELEASE: Beautiful Soup 4.13.0 beta 3
by Sumana Harihareswara Jan. 8, 2025

Jan. 8, 2025

If you use the screen-scraping library Beautiful Soup (MIT license), please test Beautiful Soup 4.13.0b3, now available on PyPI: https://pypi.org/project/beautifulsoup4/4.13.0b3/ pip install beautifulsoup4==4.13.0b3 Maintainer Leonard Richardson hopes to get feedback before the final release, which he targets for early February. Key changes from 4.12.3 (Jan. 2024): * dropping support for Python 3.6 * "a new feature (the ElementFilter class) which makes it easy to swap in your own matching logic for Beautiful Soup's default logic when calling methods like find()." * type hints in the Beautiful Soup code base; Richardson requests "feedback from people who use type hints when developing with Beautiful Soup... There might be some changes to the type hint system it would be good to make before doing a full 4.13.0 release." * "a larger-than-usual number of deprecations and changes that may break backwards compatibility" If you have questions, send them to the discussion group: https://groups.google.com/forum/?fromgroups#!forum/beautifulsoup . If you find a bug, file it on Launchpad https://bugs.launchpad.net/beautifulsoup/ . If it's a security vulnerability, report it confidentially through Tidelift: https://tidelift.com/security . Leonard Richardson writes: ------ Hi, everyone, I've done a lot of on-and-off work on Beautiful Soup 4.13.0 over the past few months, and it's added up to enough that I've decided to do another beta release before publishing it to the world. I hope to publish the final 4.13.0 release in early February. One non-code change is that I've cleaned up the docstrings and added API docs, generated from those docstrings, to the Beautiful Soup documentation. For the time being you can see the 4.13.0 documentation here, https://www.crummy.com/software/BeautifulSoup/bs4/doc/4.13.0/ and here is the generated API doc portion of that documentation. https://www.crummy.com/software/BeautifulSoup/bs4/doc/4.13.0/api/modules.ht… I've attached the entire 4.13.0 changelog to the bottom of this message, but here are the most significant changes *since the previous beta* last year: * The html5 formatter is much less aggressive about escaping ampersands, in a way that generates cleaner HTML but could break your project's test suite if you compare Beautiful Soup's output to pregenerated HTML snapshots. * The ElementFilter API has been changed slightly and is now finalized. * A number of new generators have been added which yield the element itself before beginning to traverse the tree, e.g. PageElement.self_and_parents. * Methods like Tag.extend and PageElement.insert_after now return the elements that were inserted. Since this is a prerelease version, you'll have to explicitly ask pip to install it, e.g. from the command line: `pip install beautifulsoup4==4.13.0b3` or by putting something like this in your requirements.txt: `beautifulsoup4==4.13.0b3` ------ The full changelog is available in the 4.13.0 beta 3 release announcement: https://groups.google.com/g/beautifulsoup/c/cX5m7s8v9TM/m/HHXWmwjdBwAJ For a summary of the previous beta release (March 2024): https://groups.google.com/g/beautifulsoup/c/9w_PEBCaM6c/m/RrIaqGcYAgAJ Documentation, guidance for enterprise users, and more at the project homepage: https://www.crummy.com/software/BeautifulSoup/ best, Sumana Harihareswara

TatSu 5.13.0
by Juancarlo Añez Jan. 7, 2025

Jan. 7, 2025

竜 TatSu is a tool that takes grammars in a variation of EBNF as input, and outputs memoizing (Packrat) PEG parsers in Python. In this release: - remove comments_re and eol_comments_re from parser configuration (ParserConfig). Use comments and/or eol_comments instead (#351) - do not apply re.MULTILINE to compiled regexes. Users must add (?m) to the expressions for multiline (#351) - cache compiled regexes for performance - fix bug in positive joins (#342) - test with Python 3.13 and latest libraries -- Juancarlo Añez mailto:apalala@gmail.com

Guppy 3/Heapy 3.1.5
by YiFei Zhu Jan. 3, 2025

Jan. 3, 2025

I am happy to announce Guppy 3 3.1.5 Guppy 3 is a library and programming environment for Python, currently providing in particular the Heapy subsystem, which supports object and heap memory sizing, profiling and debugging. It also includes a prototypical specification language, the Guppy Specification Language (GSL), which can be used to formally specify aspects of Python programs and generate tests and documentation from a common source. Guppy 3 is a fork of Guppy-PE, created by Sverker Nilsson for Python 2. This release adds support for Python 3.13, and support for Python 3.8 was dropped. Code for Remote & Monitor has been removed since it no longer worked since Python 3.9 (I hope PEP 734 will change this in the future). Other libraries such as aiomanhole might provide similar functionality with a much simpler implementation. This release also fixes a few bugs, including: o Fix -Wmissing-braces compile warning o Added some error handling code paths to bitset License: MIT The project homepage is on GitHub: https://github.com/zhuyifei1999/guppy3 Enjoy and Happy New Year, YiFei Zhu
