TatSu 5.13.0
by Juancarlo Añez Sept. 27, 2025

Sept. 27, 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

Python 3.14.0a7, 3.13.3, 3.12.10, 3.11.12, 3.10.17 and 3.9.22 are now available
by Hugo van Kemenade April 8, 2025

April 8, 2025

Not one, not two, not three, not four, not five, but six releases! Is this the most in a single day? 3.12-3.14 were regularly scheduled, and we had some security fixes to release in 3.9-3.11 so let’s make a big day of it. This also marks the last bugfix release of 3.12 as it enters the security-only phase. Python 3.14.0a7 Here comes the final alpha! This means we have just four weeks until the first beta to get those last features into 3.14 before the feature freeze on 2025-05-06! https://www.python.org/downloads/release/python-3140a7/ This is an early developer preview of Python 3.14 Major new features of the 3.14 series, compared to 3.13: Python 3.14 is still in development. This release, 3.14.0a7, is the last 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 758: Allow except and except* expressions without parentheses - PEP 761: Python 3.14 and onwards no longer provides PGP signatures for release artifacts. Instead, Sigstore is recommended for verifiers. - PEP 765: disallow return/break/continue that exit a finally block - PEP 768: Safe external debugger interface for CPython - A new type of interpreter. For certain newer compilers, this interpreter provides significantly better performance. Opt-in for now, requires building from source. - UUID versions 6-8 are now supported by the uuid module, and generation of versions 3-5 and 8 are up to 40% faster. - Improved error messages - Python removals and deprecations - 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 the first beta, 3.14.0b1, currently scheduled for 2025-05-06. After this, no new features can be added but bug fixes and docs improvements are allowed – and encouraged! Python 3.13.3 This is the third maintenance release of Python 3.13. Python 3.13 is the newest major release of the Python programming language, and it contains many new features and optimizations compared to Python 3.12. 3.13.3 is the latest maintenance release, containing almost 320 bugfixes, build improvements and documentation changes since 3.13.2. https://www.python.org/downloads/release/python-3133/ Python 3.12.10 This is the tenth maintenance release of Python 3.12. Python 3.12.10 is the latest maintenance release of Python 3.12, and the last full maintenance release. Subsequent releases of 3.12 will be security-fixes only. This last maintenance release contains about 230 bug fixes, build improvements and documentation changes since 3.12.9. https://www.python.org/downloads/release/python-31210/ Python 3.11.12 This is a security release of Python 3.11: - gh-106883: Fix deadlock in threaded application when using sys._current_frames - gh-131809: Upgrade vendored expat to 2.7.1 - gh-80222: Folding of quoted string in display_name violates RFC - gh-121284: Invalid RFC 2047 address header after refolding with email.policy.default - gh-131261: Update libexpat to 2.7.0 - gh-105704: [CVE-2025-0938] urlparse does not flag hostname containing [ or ] as incorrect - gh-119511: OOM vulnerability in the imaplib module https://www.python.org/downloads/release/python-31112/ Python 3.10.17 This is a security release of Python 3.10: - gh-131809: Upgrade vendored expat to 2.7.1 - gh-80222: Folding of quoted string in display_name violates RFC - gh-121284: Invalid RFC 2047 address header after refolding with email.policy.default - gh-131261: Update libexpat to 2.7.0 - gh-105704: CVE-2025-0938 urlparse does not flag hostname containing [ or ] as incorrect - gh-119511: OOM vulnerability in the imaplib module https://www.python.org/downloads/release/python-31017/ Python 3.9.22 This is a security release of Python 3.9: - gh-131809 and gh-131261: Upgrade vendored expat to 2.7.1 - gh-121284: Invalid RFC 2047 address header after refolding with email.policy.default - gh-105704: CVE-2025-0938 urlparse does not flag hostname containing [ or ] as incorrect - gh-119511: OOM vulnerability in the imaplib module https://www.python.org/downloads/release/python-3922/ Please upgrade! Please test! We highly recommend upgrading 3.9-3.13 and we encourage you to test 3.14. And now for something completely different On Saturday, 5th April, 3.141592653589793 months of the year had elapsed. Enjoy the new releases Thanks to all of the many volunteers who help make Python Development and these releases possible!
