Farewell, Python 3.4
by Larry Hastings 08 May '19

08 May '19

It's with a note of sadness that I announce the final retirement of Python 3.4. The final release was back in March, but I didn't get around to actually closing and deleting the 3.4 branch until this morning. Python 3.4 introduced many features we all enjoy in modern Python--the asyncio, ensurepip, and enum packages, just to name three. It's a release I hope we all remember fondly. My eternal thanks to all the members of the release team that worked on Python 3.4: Georg Brandl Julien Palard Martin von Löwis Ned Deily Steve Dower Terry Reedy and all the engineers of the Python infrastructure team. Special thanks to Benjamin Peterson and Ned Deily, who frequently scurried around behind the scenes cleaning up the messes I cluelessly left in my wake. Having closed 3.4, I am now retired as Python 3.4 Release Manager. I regret to inform all of you that you're still stuck with me as Python 3.5 Release Manager until sometime next year. My very best wishes, //arry/

[RELEASE] Python 3.8.0a4 is now available for testing
by Łukasz Langa 07 May '19

07 May '19

It's time for the LAST alpha of Python 3.8.0. Go get it here: https://www.python.org/downloads/release/python-380a4/ <https://www.python.org/downloads/release/python-380a4/> Python 3.8.0a4 is the fourth and final alpha release of Python 3.8, the next feature release of Python. During the alpha phase, Python 3.8 remains under heavy development: additional features will be added and existing features may be modified or deleted. Please keep in mind that this is a preview release and its use is not recommended for production environments. The first beta release, 3.8.0b1, is planned for 2019-05-31. The release has slipped a week because of me being overwhelmed with PyCon US this year. There was also a release blocker and a breaking change to ElementTree. Anyway, sorry for the wait! I moved the planned date of beta1 a few days to make up for it. If you have a feature you're working on and you'd like to see it in 3.8.0, NOW IS THE TIME TO ACT. Please don't wait until May 30th, get a proper review and land your change as soon as possible. Q: Can I get my feature in after that date if I ask nicely? A: Yes, of course. I will release it in Python 3.9. - Ł

Pythran 0.9.2 - koailh
by Serge Guelton 05 May '19

05 May '19

Hi folks, and sorry for the double posting if any. It's my great pleasure to announce the release of Pythran 0.9.2, codenamed koailh. Pythran is an ahead of time compiler for scientific kernels written in Python. It is backward-compatible with Python (no language extension) and can take advantage of OpenMP annotations and automatic SIMD instruction generation. It's been more than four months since last release, so there's quite a lot of changes. The detailed changelog is available online: https://pythran.readthedocs.io/en/latest/ Notable Changes =============== In addition to bugfixes and new function support, the most significant changes are the support of a special notation to describe optional argument in Pythran annotations: #pythran export foo(int, int?) This notation is equivalent to: #pythran export foo(int) #pythran export foo(int, int) This release also introduces a new dependency on the beniget package that provides use-def chains construction for Python code: https://github.com/serge-sans-paille/beniget A significant memory leak when converting extended slice from pythran to python has been spoted and fixed. In total, a great deal of 43 issues have been closed! https://github.com/serge-sans-paille/pythran/issues?utf8=%E2%9C%93&q=is%3Ai… Sample Code =========== As usual, I like to demonstrate Pythran through a small benchmark that used to be unsupported and now provides a nice x6 speedup (without xsimd) up to (with xsimd, non-strided version) over Python reference: import numpy as np #pythran export f_dist(float64[:,:], float64[:,:]) #pythran export f_dist(float64[::,::], float64[::,::]) def f_dist(X1, X2): return np.sum(np.abs(X1[:, None, :] - X2), axis=-1) (from https://stackoverflow.com/questions/55854611/efficient-way-of-vectorizing-d…) Download ======== You can retrieve the package through PyPI: https://pypi.org/project/pythran/ Download the source on GitHub: https://github.com/serge-sans-paille/pythran Or using the conda package, now available for Windows in addition to Linux and OSX through conda-forge https://anaconda.org/conda-forge/pythran Thanks ====== The following people have contributed to this version, through bug reports or commits, in no particular order: - Yann Diorcet - Neal Becker - Ashwin Vishnu - David Menéndez Hurtado - Jean Laroche - Anubhab Haldar - Thierry Dumont - "keke ge-smile" - "garanews" - Said Hadjout - Rodrigo Iga - Pierrick Brunet - Franck Cornevaux-Juignet Special thoughts to these last two, they reported bugs in 2013 and 2014, and the associated fixes only happened in 2019 ^^! Contribute ========== If you've been brave enough to read this whole mail, the next step is to support Pythran! You can donate your time through bug reports and fixes, give a small motivation boost through a gentle email, or just use it and share the joy. If you need important development in Pythran, you can drive the roadmap! Send an email to the mailing list (or to my personnal email if you're too shy). ++ Serge
