On behalf of the entire Python development community, and the currently serving Python release team in particular, I’m pleased to announce the release of Python 3.9.0a5. Get it here: https://www.python.org/downloads/release/python-390a5/ <https://www.python.org/downloads/release/python-390a5/> This is an early developer preview of Python 3.9 Python 3.9 is still in development. This releasee, 3.9.0a5 is the fifth of six 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 (2020-05-18) and, if necessary, may be modified or deleted up until the release candidate phase (2020-08-10). 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 Many new features for Python 3.9 are still being planned and written. Among the new major new features and changes so far: PEP 584 <https://www.python.org/dev/peps/pep-0584/>, Union Operators in dict 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 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) are now sped up using PEP 570 <https://www.python.org/dev/peps/pep-0570> vectorcall 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/>. (Hey, fellow core developer, if a feature you find important is missing from this list, let Łukasz know <mailto:lukasz@python.org>.) The next pre-release, the last alpha release of Python 3.9, will be 3.9.0a6. It is currently scheduled for 2020-04-22. Until then, stay safe!

What is CodeCov on pull request? Does anyone use it?
by Victor Stinner 02 Mar '20

02 Mar '20

Hi, There is a new "CodeCov" thing on Python pull requests which adds a giant comment with many numbers and statistics and then mark my pull request as "failed" (red). I know the concept of code coverage, ok. But who uses this service? Does it *have to* send emails to say: "Merging #18743 into master will increase coverage by 0.00%. The diff coverage is n/a." https://github.com/python/cpython/pull/18743#issuecomment-593426007 My PR changes distutils, but the comment also says "Lib/ftplib.py 63.85% <0.00%> (-6.06%)". The service doesn't seem reliable. A distutils change should have no impact on ftplib coverage. Or someone should explain me how it's supposed to work. https://devguide.python.org/coverage/ says nothing about CodeCov. Would it be possible to disable this service? Or can I opt-out somehow to no longer get emails from it nor see such comments on my PRs? Victor -- Night gathers, and now my watch begins. It shall not end until my death.

Policy around compile-time flags in bugfix releases
by Łukasz Langa 02 Mar '20

02 Mar '20

Hey there, the release managers noticed Stefan adding a new compile flag and backporting it to (soon to be) 3.7.7 and (eventually to be) 3.8.3. Context: https://bugs.python.org/issue39794 Should this go in? It does look like a new feature to us. - Ł and Ned

bpo email problems - Is there someone in the infra boat?
by Antoine Pitrou 01 Mar '20

01 Mar '20

Hello, In the end of 2019 I've reported an issue where all b.p.o notifications would get into my spam folder (apparently because my ISP's mail server marks them as suspicious in the e-mail headers): https://github.com/python/psf-infra-meta/issues/16 Then since the beginning of 2020 I haven't been receiving b.p.o notifications anymore. Not even in my spam folder: https://github.com/python/psf-infra-meta/issues/54 I've never had a single response on those two issues. This means that I miss all messages that are being posted on issues for which I am in the nosy list, except in extremely rare cases when I visit an issue for unrelated reasons (I rarely find myself casually browsing the bug tracker these days). I realize that e-mail delivery issues are not necessarily trivial. But at least I would hope that problems like this don't get completely ignored. Is there a way to get this sorted out? Regards Antoine.
