[Python-announce]NumPy 1.21.2 released
by Charles R Harris 15 Aug '21

15 Aug '21

Hi All, On behalf of the NumPy team I am pleased to announce the release of NumPy 1.21.2. NumPy 1.21.2 is a maintenance release that fixes bugs discovered after 1.21.1. It also provides 64 bit manylinux Python 3.10.0rc1 wheels for downstream testing. Note that Python 3.10 is not yet final. There is also preliminary support for Windows on ARM64 builds, but there is no OpenBLAS for that platform and no wheels are available. The Python versions supported for this release are 3.7-3.9. The 1.21.2 release is compatible with Python 3.10.0rc1 and Python 3.10 will be officially supported after it is released. The previous problems with gcc-11.1 have been fixed by gcc-11.2, check your version if you are using gcc-11. Wheels can be downloaded from PyPI <https://pypi.org/project/numpy/1.21.2/>; source archives, release notes, and wheel hashes are available on Github <https://github.com/numpy/numpy/releases/tag/v1.21.2>. Linux users will need pip >= 0.19.3 in order to install manylinux2010 and manylinux2014 wheels. *Contributors* A total of 10 people contributed to this release. People with a "+" by their names contributed a patch for the first time. - Bas van Beek - Carl Johnsen + - Charles Harris - Gwyn Ciesla + - Matthieu Dartiailh - Matti Picus - Niyas Sait + - Ralf Gommers - Sayed Adel - Sebastian Berg *Pull requests merged* A total of 18 pull requests were merged for this release. - #19497: MAINT: set Python version for 1.21.x to ``<3.11`` - #19533: BUG: Fix an issue wherein importing ``numpy.typing`` could raise - #19646: MAINT: Update Cython version for Python 3.10. - #19648: TST: Bump the python 3.10 test version from beta4 to rc1 - #19651: TST: avoid distutils.sysconfig in runtests.py - #19652: MAINT: add missing dunder method to nditer type hints - #19656: BLD, SIMD: Fix testing extra checks when ``-Werror`` isn't applicable... - #19657: BUG: Remove logical object ufuncs with bool output - #19658: MAINT: Include .coveragerc in source distributions to support... - #19659: BUG: Fix bad write in masked iterator output copy paths - #19660: ENH: Add support for windows on arm targets - #19661: BUG: add base to templated arguments for platlib - #19662: BUG,DEP: Non-default UFunc signature/dtype usage should be deprecated - #19666: MAINT: Add Python 3.10 to supported versions. - #19668: TST,BUG: Sanitize path-separators when running ``runtest.py`` - #19671: BLD: load extra flags when checking for libflame - #19676: BLD: update circleCI docker image - #19677: REL: Prepare for 1.21.2 release.

I'm happy to announce the release of Pygments 2.10. Pygments is a generic syntax highlighter written in Python. Pygments 2.10 provides five new lexers and various improvements to existing lexers. Please have a look at the changelog <https://pygments.org/docs/changelog/>. Report bugs and feature requests in the issue tracker: <https://github.com/pygments/pygments/issues>. Thanks go to all the contributors of these lexers, and to all those who reported bugs and waited very patiently for this release. Download it from <https://pypi.org/project/Pygments/>, or look at the demonstration at <https://pygments.org/demo/>. Enjoy, Matthäus

[RELEASE] Python 3.10.0rc1 is available
by Pablo Galindo Salgado 04 Aug '21

04 Aug '21

Python 3.10.0 is almost ready. This release, 3.10.0rc1, is the penultimate release preview. You can get it here: https://www.python.org/downloads/release/python-3100rc1/ *This is the first release candidate of Python 3.10* This release, **3.10.0rc1**, is the penultimate release preview. Entering the release candidate phase, only reviewed code changes which are clear bug fixes are allowed between this release candidate and the final release. The second candidate and the last planned release preview is currently planned for 2021-09-06 while the official release is planned for 2021-10-04. There will be no ABI changes from this point forward in the 3.10 series and the goal is that there will be as few code changes as possible. *Call to action* Core developers: all eyes on the docs now - Are all your changes properly documented? - Did you notice other changes you know of to have insufficient documentation? Community members We strongly encourage maintainers of third-party Python projects to prepare their projects for 3.10 compatibilities during this phase. As always, report any issues to the Python bug tracker <https://bugs.python.org/>. Please keep in mind that this is a preview release and its use is **not** recommended for production environments. *And now for something completely different* In theoretical physics, quantum chromodynamics (QCD) is the theory of the strong interaction between quarks and gluons, the fundamental particles that make up composite hadrons such as the proton, neutron, and pion. The QCD analog of electric charge is a property called color. Gluons are the force carrier of the theory, just as photons are for the electromagnetic force in quantum electrodynamics. There are three kinds of charge in QCD (as opposed to one in quantum electrodynamics or QED) that are usually referred to as "color charge" by loose analogy to the three kinds of color (red, green and blue) perceived by humans. Other than this nomenclature, the quantum parameter "color" is completely unrelated to the everyday, familiar phenomenon of color. *We hope you enjoy those new releases!* 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 organization contributions to the Python Software Foundation. Regards from cloudy London, Your friendly release team, Pablo Galindo @pablogsal Ned Deily @nad Steve Dower @steve.dower
