TatSu 5.13.0
by Juancarlo Añez Dec. 25, 2025

Dec. 25, 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:[email protected]

ANN: numexpr 2.13.0 released
by Francesc Alted Sept. 24, 2025

Sept. 24, 2025

========================= Announcing NumExpr 2.13.0 ========================= Hi everyone, NumExpr 2.13.0 introduced a bunch of new features including new bitwise operators (&, |, ^, ~), floor division (//). It also adds many new functions (like hypot, log2, maximum, minimum, nextafter...). Thanks to Luke Shaw for these contributions. Project documentation is available at: https://numexpr.readthedocs.io/ Changes from 2.12.1 to 2.13.0 ----------------------------- * New functionality has been added: * Bitwise operators (and, or, not, xor): `&, |, ~, ^` * New binary arithmetic operator for floor division: `//` * New functions: `signbit`, `hypot`, `copysign`, `nextafter`, `maximum`, `minimum`, `log2`, `trunc`, `round` and `sign`. * Also enables integer outputs for integer inputs for `abs`, `fmod`, `copy`, `ones_like`, `sign` and `round`. Thanks to Luke Shaw for the contributions. * New wheels for Python 3.14 and 3.14t are provided. What's Numexpr? --------------- Numexpr is a fast numerical expression evaluator for NumPy. With it, expressions that operate on arrays (like "3*a+4*b") are accelerated and use less memory than doing the same calculation in Python. It has multi-threaded capabilities, as well as support for Intel's MKL (Math Kernel Library), which allows an extremely fast evaluation of transcendental functions (sin, cos, tan, exp, log...) while squeezing the last drop of performance out of your multi-core processors. Look here for a some benchmarks of numexpr using MKL: https://github.com/pydata/numexpr/wiki/NumexprMKL Its only dependency is NumPy (MKL is optional), so it works well as an easy-to-deploy, easy-to-use, computational engine for projects that don't want to adopt other solutions requiring more heavy dependencies. Where I can find Numexpr? ------------------------- The project is hosted at GitHub in: https://github.com/pydata/numexpr You can get the packages from PyPI as well (but not for RC releases): http://pypi.python.org/pypi/numexpr Documentation is hosted at: http://numexpr.readthedocs.io/en/latest/ Share your experience --------------------- Let us know of any bugs, suggestions, gripes, kudos, etc. you may have. Enjoy data!

ANN: psutil 7.1.1 released
by Giampaolo Rodola' Sept. 17, 2025

Sept. 17, 2025

Hello all, I'm glad to announce the release of psutil 7.1.0: https://github.com/giampaolo/psutil About ===== psutil (process and system utilities) is a cross-platform library for retrieving information on running processes and system utilization (CPU, memory, disks, network) in Python. It is useful mainly for system monitoring, profiling and limiting process resources and management of running processes. It implements many functionalities offered by command line tools such as: ps, top, lsof, netstat, ifconfig, who, df, kill, free, nice, ionice, iostat, iotop, uptime, pidof, tty, taskset, pmap. It currently supports Linux, Windows, macOS, Sun Solaris, FreeBSD, OpenBSD, NetBSD and AIX. Supported Python versions are cPython 3.6+ and PyPy. What's new ========== 2025-09-17 **Enhancements** - #2581, [Windows]: publish ARM64 wheels. (patch by Matthieu Darbois) - #2571, [FreeBSD]: Dropped support for FreeBSD 8 and earlier. FreeBSD 8 was maintained from 2009 to 2013. - #2575: introduced `dprint` CLI tool to format .yml and .md files. **Bug fixes** - #2473, [macOS]: Fix build issue on macOS 11 and lower. - #2494, [Windows]: All APIs dealing with paths, such as `Process.memory_maps()`_, `Process.exe()`_ and `Process.open_files()`_ does not properly handle UNC paths. Paths such as ``\\??\\C:\\Windows\\Temp`` and ``'\\Device\\HarddiskVolume1\\Windows\\Temp'`` are now converted to ``C:\\Windows\\Temp``. (patch by Ben Peddell) - #2506, [Windows]: Windows service APIs had issues with unicode services using special characters in their name. - #2514, [Linux]: `Process.cwd()`_ sometimes fail with `FileNotFoundError` due to a race condition. - #2526, [Linux]: `Process.create_time()`_, which is used to univocally identify a process over time, is subject to system clock updates, and as such can lead to `Process.is_running()`_ returning a wrong result. A monotonic creation time is now used instead. (patch by Jonathan Kohler) - #2528, [Linux]: `Process.children()`_ may raise ``PermissionError``. It will now raise `AccessDenied`_ instead. - #2540, [macOS]: `boot_time()`_ is off by 45 seconds (C precision issue). - #2541, 2570_, 2578_ [Linux], [macOS], [NetBSD]: `Process.create_time()`_ does not reflect system clock updates. - #2542: if system clock is updated `Process.children()`_ and `Process.parent()`_ may not be able to return the right information. - #2545: [Illumos]: Fix handling of MIB2_UDP_ENTRY in `net_connections()`_. - #2552, [Windows]: `boot_time()`_ didn't take into account the time spent during suspend / hibernation. - #2560, [Linux]: `Process.memory_maps()`_ may crash with `IndexError` on RISCV64 due to a malformed `/proc/{PID}/smaps` file. (patch by Julien Stephan) - #2586, [macOS], [CRITICAL]: fixed different places in C code which can trigger a segfault. - #2604, [Linux]: `virtual_memory()`_ "used" memory does not match recent versions of ``free`` CLI utility. (patch by Isaac K. Ko) - #2605, [Linux]: `psutil.sensors_battery()` reports a negative amount for seconds left. - #2607, [Windows]: ``WindowsService.description()`` method may fail with ``ERROR_NOT_FOUND``. Now it returns an empty string instead. - 2610:, [macOS], [CRITICAL]: fix `cpu_freq()`_ segfault on ARM architectures. **Compatibility notes** - #2571: dropped support for FreeBSD 8 and earlier.

PyCA cryptography 46.0.1 has been released to PyPI. cryptography includes both high level recipes and low level interfaces to common cryptographic algorithms such as symmetric ciphers, asymmetric algorithms, message digests, X.509, key derivation functions, and much more. We support Python 3.8+, and PyPy3 3.11. Changelog (https://cryptography.io/en/latest/changelog/#v46-0-1) * Fixed an issue where users installing via pip on Python 3.14 development versions would not properly install a dependency. * Fixed an issue building the free-threaded macOS 3.14 wheels. Changelog (https://cryptography.io/en/latest/changelog/#v46-0-0) * BACKWARDS INCOMPATIBLE: Support for Python 3.7 has been removed. * Support for OpenSSL < 3.0 is deprecated and will be removed in the next release. * Support for x86_64 macOS (including publishing wheels) is deprecated and will be removed in two releases. We will switch to publishing an arm64 only wheel for macOS. * Support for 32-bit Windows (including publishing wheels) is deprecated and will be removed in two releases. Users should move to a 64-bit Python installation. * Updated Windows, macOS, and Linux wheels to be compiled with OpenSSL 3.5.3. * We now build ppc64le manylinux wheels and publish them to PyPI. * We now build win_arm64 (Windows on Arm) wheels and publish them to PyPI. * Added support for free-threaded Python 3.14. * Removed the deprecated get_attribute_for_oid method on CertificateSigningRequest. Users should use get_attribute_for_oid() instead. * Removed the deprecated CAST5, SEED, IDEA, and Blowfish classes from the cipher module. These are still available in Decrepit cryptography. * In X.509, when performing a PSS signature with a SHA-3 hash, it is now encoded with the official NIST SHA3 OID. -Paul Kehrer (reaperhulk)
