plum-py 0.7.2 release (Pack / Unpack Memory bytes)
by Dan Gass Nov. 10, 2021

Nov. 10, 2021

I am pleased to announce the availability of beta release 0.7.2 of the "plum -py" package. This pure Python package provides classes and utility functions to transform byte sequences into Python objects and back. While similar in purpose to Python's standard library ``struct`` module, this package provides a larger set of format specifiers and is extensible, allowing you to easily create complex ones of your own. Docs: https://plum-py.readthedocs.io/en/latest/index.html PyPi: https://pypi.org/project/plum-py/ Repo: https://gitlab.com/dangass/plum Install: pip install plum-py License: MIT With Regards, Dan Gass (dan.gass at gmail) Change List ========= - Support packing ``bytearray()`` with ``ItemsX`` transforms. - Previously when an exception occurred during pack/unpack operation and the dump records were half baked, creating dump representation for exception message resulted in a different error and didn't allow the dump to be seen and used. - Add ``AttrDict`` and ``AttrDictX`` for packing/unpacking dictionaries where members are accessible via attribute syntax.

Hi all, On behalf of the SciPy development team I'm pleased to announce the release of SciPy 1.7.2, which is a bug fix release that includes wheels for Python 3.10 on many platforms. Many thanks to upstream developers in the ecosystem for their assistance in making this possible. Sources and binary wheels can be found at: https://pypi.org/project/scipy/ and at: https://github.com/scipy/scipy/releases/tag/v1.7.2 <https://github.com/scipy/scipy/releases/tag/v1.6.3> <https://github.com/scipy/scipy/releases/tag/v1.6.1> One of a few ways to install this release with pip: pip install scipy==1.7.2 ==================== SciPy 1.7.2 Release Notes ==================== SciPy 1.7.2 is a bug-fix release with no new features compared to 1.7.1. Notably, the release includes wheels for Python 3.10, and wheels are now built with a newer version of OpenBLAS, 0.3.17. Python 3.10 wheels are provided for MacOS x86_64 (thin, not universal2 or arm64 at this time), and Windows/Linux 64-bit. Many wheels are now built with newer versions of manylinux, which may require newer versions of pip.

[RELEASE] Python 3.9.8 and 3.11.0a2 are now available
by Łukasz Langa Nov. 5, 2021

Nov. 5, 2021

Tcl/Tk updates With the recent release of macOS 12 Monterey, we noticed that tkinter file dialogs are failing to show up on this new operating system, including in our built-in IDLE. Thanks to rapid help from the Tk team, and Marc Culler in particular, we were able to fix the issue by bundling Python 3.9.8 and Python 3.11.0a2 with a fixed Tcl/Tk version. In 3.9.8 it’s a patched 8.6.11 release while 3.11.0a2 is rocking the bleeding-edge 8.6.12rc1. Since the issue also affected our latest stable version, 3.10.0, an updated macOS installer for this version was issued. You can recognize it by the post2 version appendix: python-3.10.0post2-macos11.pkg <https://www.python.org/ftp/python/3.10.0/python-3.10.0post2-macos11.pkg>. We didn’t have to bump the version number of Python itself since there are no Python source differences between this package and the original 3.10.0. The only difference is the bundled patched Tcl/Tk library. Initially the original 3.10.0 installer was removed from the website after all URLs got updated to point to the patched version but it turned out this breaks some workflows <https://discuss.python.org/t/disappearing-macos-packages-on-python-org/11737> so the patched installer is now also available under the original filename. <https://discuss.python.org/t/python-3-9-8-and-3-11-0a2-are-now-available/11…>Python 3.9.8 Get it here: https://www.python.org/downloads/release/python-398/ <https://www.python.org/downloads/release/python-398/> Python 3.9.8 is the seventh maintenance release of the legacy 3.9 series. Python 3.10 is now the latest feature release series of Python 3. Get the latest release of 3.10.x here <https://python.org/downloads/>. There’s been 202 commits since 3.9.7 which shows that there’s still considerable interest in improving Python 3.9. To compare, at the same stage of the release cycle Python 3.8 received over 25% fewer commits. See the changelog <https://docs.python.org/release/3.9.8/whatsnew/changelog.html> for details on what changed. On macOS, the default installer is now the new universal2 variant. It’s compatible with Mac OS X 10.9 and newer, including macOS 11 Big Sur and macOS 12 Monterey. You may need to upgrade third-party components, like pip, to the newest versions. You may experience differences in behavior in IDLE and other Tk-based applications due to using the newest version of Tk. As always, if you encounter problems when using this installer variant, please check https://bugs.python.org <https://bugs.python.org/> for existing reports and for opening new issues. The next Python 3.9 maintenance release will be 3.9.9, currently scheduled for 2022-01-03. <https://discuss.python.org/t/python-3-9-8-and-3-11-0a2-are-now-available/11…>Python 3.11.0a2 Get it here: https://www.python.org/downloads/release/python-3110a2/ <https://www.python.org/downloads/release/python-3110a2/> Python 3.11 is still in development. This release, 3.11.0a2 is the second 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 (2022-05-06) and, if necessary, may be modified or deleted up until the release candidate phase (2022-08-01). Please keep in mind that this is a preview release and its use is not recommended for production environments. Many new features for Python 3.11 are still being planned and written. Among the new major new features and changes so far: PEP 657 <https://www.python.org/dev/peps/pep-0657/> – Include Fine-Grained Error Locations in Tracebacks The Faster CPython Project 1 <https://github.com/faster-cpython> is already yielding some exciting results: this version of CPython 3.11 is ~12% faster on the geometric mean of the PyPerformance benchmarks <>, compared to 3.10.0. (Hey, fellow core developer, if a feature you find important is missing from this list, let Pablo know <mailto:pablogsal@python.org>.) The next pre-release of Python 3.11 will be 3.11.0a3, currently scheduled for Monday, 2021-12-06. <https://discuss.python.org/t/python-3-9-8-and-3-11-0a2-are-now-available/11…>We hope you enjoy the new releases Your friendly release team, Ned Deily @nad <https://discuss.python.org/u/nad> Pablo Galindo Salgado @pablogsal <https://discuss.python.org/u/pablogsal> Steve Dower @steve.dower <https://discuss.python.org/u/steve.dower> Łukasz Langa @ambv <https://discuss.python.org/u/ambv>

NumPy 1.21.4 release.
by Charles R Harris Nov. 4, 2021

Nov. 4, 2021

Hi All, On behalf of the NumPy team I am pleased to announce the release of NumPy 1.21.4. NumPy 1.21.4 is a maintenance release that fixes a few bugs discovered after 1.21.3. The most important fix here is for the NumPy header files to make them work for both x86_64 and M1 hardware when included in the Mac universal2 wheels. Previously, the header files only worked for M1 and this caused problems for folks building x86_64 extensions. This problem was not seen before Python 3.10 because there were thin wheels for x86_64 that had precedence. This release also provides thin x86_64 Mac wheels for Python 3.10. Note that there are *no* manylinux1 wheels, the needed CentOS 5 repos have gone missing. Make sure you upgrade your pip version if you have problems downloading the correct wheels. The Python versions supported in this release are 3.7-3.10. If you want to compile your own version using gcc-11 you will need to use gcc-11.2+ to avoid problems. Wheels can be downloaded from PyPI <https://pypi.org/project/numpy/1.21.4/>; source archives, release notes, and wheel hashes are available on Github <https://github.com/numpy/numpy/releases/tag/v1.21.4>. Linux users will need pip >= 0.19.3 in order to install manylinux2010 and manylinux2014 wheels. A recent version of pip is needed to install the universal2 macos wheels. *Contributors* A total of 7 people contributed to this release. People with a "+" by their names contributed a patch for the first time. - Bas van Beek - Charles Harris - Isuru Fernando - Matthew Brett - Sayed Adel - Sebastian Berg - 傅立业（Chris Fu） + *Pull requests merged* A total of 9 pull requests were merged for this release. - #20278: BUG: Fix shadowed reference of `dtype` in type stub - #20293: BUG: Fix headers for universal2 builds - #20294: BUG: ``VOID_nonzero`` could sometimes mutate alignment flag - #20295: BUG: Do not use nonzero fastpath on unaligned arrays - #20296: BUG: Distutils patch to allow for 2 as a minor version (!) - #20297: BUG, SIMD: Fix 64-bit/8-bit integer division by a scalar - #20298: BUG, SIMD: Workaround broadcasting SIMD 64-bit integers on MSVC... - #20300: REL: Prepare for the NumPy 1.21.4 release. - #20302: TST: Fix a ``Arrayterator`` typing test failure Cheers, Charles Harris

I am pleased to announce the availability of beta release 0.7.1 of the "plum -py" package. This pure Python package provides classes and utility functions to transform byte sequences into Python objects and back. While similar in purpose to Python's standard library ``struct`` module, this package provides a larger set of format specifiers and is extensible, allowing you to easily create complex ones of your own. Docs: https://plum-py.readthedocs.io/en/latest/index.html PyPi: https://pypi.org/project/plum-py/ Repo: https://gitlab.com/dangass/plum Install: pip install plum-py License: MIT With Regards, Dan Gass (dan.gass at gmail) Change List ========= - Support ``BitFields`` usage as ``typ`` in structure ``bitfield_member()``.
