NumPy 1.23.0rc3 released
by Charles R Harris 11 Jun '22

11 Jun '22

Hi All, On behalf of the NumPy team, I'm pleased to announce the release of NumPy 1.23.0rc2. The NumPy 1.23.0 release continues the ongoing work to improve the handling and promotion of dtypes, increase the execution speed, clarify the documentation, and expire old deprecations. The highlights are: - Implementation of ``loadtxt`` in C, greatly improving its performance. - Exposing DLPack at the Python level for easy data exchange. - Changes to the promotion and comparisons of structured dtypes. - Improvements to f2py. The Python versions supported in this release are 3.8-3.10, 3.11 will be supported when it comes out. Note that 32 bit wheels are only provided for Windows, all other wheels are 64 bits on account of Ubuntu, Fedora, and other Linux distributions dropping 32 bit support. All 64 bit wheels are also linked with 64 bit OpenBLAS. Wheels can be downloaded from PyPI <https://pypi.org/project/numpy/1.23.0rc3/>; source archives, release notes, and wheel hashes are available on Github <https://github.com/numpy/numpy/releases/tag/v1.23.0rc3>. *Contributors* A total of 151 people contributed to this release.

Like down quarks, strange quarks have a charge of -1/3. Like all fermions (which are particles that can not exist in the same place at the same time), strange quarks have a spin of 1/2. What makes strange quarks different from down quarks–apart from having 25 times the mass of down quarks–is that they have something that scientists call "strangeness." Strangeness is basically a resistance to decay against strong force and electromagnetism. This means that any particle that contains a strange quark can not decay due to strong force (or electromagnetism), but instead with the much slower weak force. It was believed that this was a 'strange' method of decay, which is why the scientists gave the particles that name. # We hope you enjoy the new releases!

[RELEASE] Expedited release of Python3.11.0b3!!
by Pablo Galindo Salgado 01 Jun '22

01 Jun '22

Hi everyone, Due to a known incompatibility with pytest and the previous beta release (Python 3.11.0b2) and after some deliberation, me and the rest of the release team have decided to do an expedited release of Python 3.11.0b3 so the community can continue testing their packages with pytest and therefore testing the betas as expected. # Where can I get the new release? https://www.python.org/downloads/release/python-3110b3/ # What happened? Pytest by default rewrites the AST nodes in the testing code to provide better diagnostics when something fails in the test. For doing this, it creates new AST nodes that are then compiled. In Python 3.11, after some changes in the compiler and AST nodes, these new AST nodes that pytest was creating were invalid. This causes CPython to crash in debug mode because we have several assert statements in the compiler, but in release mode this doesn't cause always a crash, but it creates potential corrupted structures in the compiler silently. In 3.11.0b3 we changed the compiler to reject invalid AST nodes, so what was a silent problem and a crash in debug mode turned into an exception being raised. We had a fix to allow the nodes that pytest is creating to work to preserve backwards compatibility but unfortunately, it didn't make it into 3.11.0b2. Is still possible to use pytest with 3.11.0b2 if you add "--assert=plain" to the pytest invocation but given how many users would have to modify their test suite invocation we decided to proceed with a new release that has the fix. # What happens with future beta releases Python 3.11.0b3 should be considered as an extra beta release. Instead of four beta releases, we will have five and the next beta release (3.11.0b4) will happen as scheduled on Thursday, 2022-06-16. # We hope you enjoy the 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. https://www.python.org/psf/ If you have any questions, please reach out to me or another member of the release team :) Your friendly release team, Ned Deily @nad https://discuss.python.org/u/nad Steve Dower @steve.dower https://discuss.python.org/u/steve.dower Pablo Galindo Salgado @pablogsal https://discuss.python.org/u/pablogsal
