Hi All, On behalf of the NumPy team I am pleased to announce that NumPy 1.19.0rc2 has been released. This NumPy release supports Python 3.6-3.8 and is marked by the removal of much technical debt: support for Python 2 has been removed, many deprecations have been expired, and documentation has been improved. The polishing of the random module continues apace with bug fixes and better usability from Cython. Perhaps the most interesting thing for users will be the availability of wheels for … [View More]aarch64 and PyPY. Downstream developers should use Cython >= 0.29.16 for Python 3.8 support and OpenBLAS >= 3.7 to avoid wrong results on the Skylake architecture. The NumPy Wheels for this release can be downloaded from PyPI <https://pypi.org/project/numpy/1.19.0rc2/>, source archives and release notes are available from Github <https://github.com/numpy/numpy/releases/tag/v1.19.0rc2>. *Contributors* A total of 124 people contributed to this release.

Never miss a talk ----------------- All talks will be made available to the attendees as live Webinars, with easy switching between tracks, as well as online streams, which will allow rewinding to watch talks you may have missed during the day. Conference Tickets ------------------ Conference tickets are available on our registration page. We have simplified and greatly reduced the prices for the EuroPython 2020 online edition: https://ep2020.europython.eu/registration/buy-tickets/ As always, all proceeds from the conference will go into our grants budget, which we use to fund financial aid for the next EuroPython edition, special workshops and other European conferences and projects: * EuroPython Society Grants Program * https://www.europython-society.org/grants We hope to see lots of you at the conference in July. Rest assured that we’ll make this a great event again — even within the limitations of running the conference online.

Participation in the sprints is free, but does require registration. We will provide the necessary collaboration tools in form of dedicated Jitsi or Zoom virtual rooms and text channels on our Discord server. EuroPython is your conference ----------------------------- EuroPython has always been a completely volunteer based effort. The organizers work hundreds of hours to make the event happen and will try very hard to create an inspiring and exciting event. However, we can only provide the setting. You, as our attendees, are the ones who fill it with life and creativity. We are very much looking forward to having you at the conference ! Help spread the word -------------------- Please help us spread this message by sharing it on your social networks as widely as possible. Thank you !

Online training June 11, 12: Docker packaging best practices for Python in production
by Itamar Turner-Trauring May 22, 2020

May 22, 2020

You’re about to ship your Python application into production using Docker: your images are going to be critical infrastructure. And that means you need to follow best practices—if you don’t, you risk wasting quite a lot of money: * You don’t want to waste hours every week waiting for slow builds. * Or even worse, you might have a production outage or security breach, costing your company orders of magnitude more money. So how can you ensure your Docker image packaging isn’t wasting your team’… [View More]

Sphinx plugin to make easier-to-navigate class documentation
by Kale Kundert May 19, 2020

May 19, 2020

I'm writing to share a Sphinx plugin I wrote, which I think makes the documentation for large classes much easier to navigate and understand. The plugin is called `autoclasstoc` and you can find the documentation here: https://autoclasstoc.readthedocs.io/en/latest/ I wrote this plugin because, while restructured text and Sphinx are great in a lot of ways, I've always been disappointed by the options for documenting classes. `autoclass` is easy to use, but hard to read because all … [View More]

Get it here: https://www.python.org/downloads/release/python-390b1/ <https://www.python.org/downloads/release/python-390b1/> This is a beta preview of Python 3.9 Python 3.9 is still in development. This release, 3.9.0b1, is the first of four planned beta release previews. Beta release previews are intended to give the … [View More]wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. Call to action We strongly encourage maintainers of third-party Python projects to test with 3.9 during the beta phase and report issues found to the Python bug tracker <https://bugs.python.org/> as soon as possible. While the release is planned to be feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (2020-08-10). Our goal is have no ABI changes after beta 4 and as few code changes as possible after 3.9.0rc1, the first release candidate. To achieve that, it will be extremely important to get as much exposure for 3.9 as possible during the beta phase. Please keep in mind that this is a preview release and its use is not recommended for production environments. Major new features of the 3.9 series, compared to 3.8 Some of the new major new features and changes in Python 3.9 are: PEP 584 <https://www.python.org/dev/peps/pep-0584/>, Union Operators in dict PEP 585 <https://www.python.org/dev/peps/pep-0585/>, Type Hinting Generics In Standard Collections PEP 593 <https://www.python.org/dev/peps/pep-0593/>, Flexible function and variable annotations PEP 602 <https://www.python.org/dev/peps/pep-0602/>, Python adopts a stable annual release cadence PEP 616 <https://www.python.org/dev/peps/pep-0616/>, String methods to remove prefixes and suffixes PEP 617 <https://www.python.org/dev/peps/pep-0617/>, New PEG parser for CPython BPO 38379 <https://bugs.python.org/issue38379>, garbage collection does not block on resurrected objects; BPO 38692 <https://bugs.python.org/issue38692>, os.pidfd_open added that allows process management without races and signals; BPO 39926 <https://bugs.python.org/issue39926>, Unicode support updated to version 13.0.0; BPO 1635741 <https://bugs.python.org/issue1635741>, when Python is initialized multiple times in the same process, it does not leak memory anymore; A number of Python builtins (range, tuple, set, frozenset, list, dict) are now sped up using PEP 590 <https://www.python.org/dev/peps/pep-0590> vectorcall; A number of Python modules (_abc, audioop, _bz2, _codecs, _contextvars, _crypt, _functools, _json, _locale, operator, resource, time, _weakref) now use multiphase initialization as defined by PEP 489 <https://www.python.org/dev/peps/pep-0489/>; A number of standard library modules (audioop, ast, grp, _hashlib, pwd, _posixsubprocess, random, select, struct, termios, zlib) are now using the stable ABI defined by PEP 384 <https://www.python.org/dev/peps/pep-0384/>.
