by Łukasz Langa 18 সেপ্টেম্বর, 2020

18 সেপ্টেম্বর, 2020

Python 3.9.0 is almost ready. This release, 3.9.0rc2, is the last planned preview before the final release of Python 3.9.0 on 2020-10-05. Get it here: https://www.python.org/downloads/release/python-390rc2/ <https://www.python.org/downloads/release/python-390rc2/> In the mean time, we strongly encourage maintainers of third-party Python projects to prepare their projects for 3.9 compatibility during this phase. As always, report any issues to the Python bug tracker <https://bugs.python.org/>. Please keep in mind that this is a preview release and its use is not recommended for production environments. Information for core developers The 3.9 branch is now accepting changes for 3.9.1. To maximize stability, the final release will be cut from the v3.9.0rc2 tag. If you need the release manager to cherry-pick any critical fixes, mark issues as release blockers and/or add him as a reviewer on a critical backport PR on GitHub. To see which changes are currently cherry-picked for inclusion in 3.9.0, look at the short-lived branch-v3.9.0 <https://github.com/python/cpython/tree/branch-v3.9.0> on GitHub. Installer news This is the first version of Python to default to the 64-bit installer on Windows. The installer now also actively disallows installation on Windows 7. Python 3.9 is incompatible with this unsupported version of Windows. 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 615 <https://www.python.org/dev/peps/pep-0615/>, Support for the IANA Time Zone Database in the Standard Library 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/>.

cherry_picker problem
by Eric V. Smith 14 সেপ্টেম্বর, 2020

14 সেপ্টেম্বর, 2020

For reasons I don't understand, https://github.com/python/cpython/pull/22229 failed to backport to 3.9. The message says: Sorry @eamanu <https://github.com/eamanu>, I had trouble checking out the |3.9| backport branch. Please backport using cherry_picker <https://pypi.org/project/cherry-picker/> on command line. I don't know if this problem with checking out the 3.9 backport branch is part of my problem or not. The backport to 3.8 succeeded. So, I'm trying to run cherry_picker, as suggested. It's set up locally with the most recent version (1.3.2). My local repo has an origin and an upstream remote: [~/local/python/cpython]$ git remote -v origin git@github.com:ericvsmith/cpython.git (fetch) origin git@github.com:ericvsmith/cpython.git (push) upstream git@github.com:python/cpython.git (fetch) upstream git@github.com:python/cpython.git (push) When I run cherry_picker, it says "Failed to push to origin ☹". I don't know why that would be, or what the implications are (except the backport not succeeding). The full output of running cherry_picker is below. As near as I can tell, there are no conflicts. Any ideas? If I can't figure it out, I'll just leave this minor documentation fix in master and 3.8, but not 3.9.

Hey all, We just recently finished working on the signup form for the upcoming 2020 Python Core Dev Sprint on Oct. 19th - 23rd. In addition to getting an general idea of (virtual) attendance, this is being used to assess the topics covered, optimal start/end times for each day, and preferred social activities. Anyone who is a CPython core developer, engaged in a core dev mentorship, or a member of the Python triage team is welcome to attend! Sign up to attend here: https://forms.gle/84NkyYt5g616fs1r5 We will be accepting late sign ups for this event since capacity is not a significant limitation, but for the purposes of scheduling the best possible times for everyone, it is requested that participants do so at their earliest convenience. Regards, Kyle Stanley

[RELEASE] Python 3.8.6rc1 is now ready for testing
by Łukasz Langa 8 সেপ্টেম্বর, 2020

8 সেপ্টেম্বর, 2020

Python 3.8.6rc1 is the release candidate of the sixth maintenance release of Python 3.8. Go get it here: https://www.python.org/downloads/release/python-386rc1/ <https://www.python.org/downloads/release/python-386rc1/> Assuming no critical problems are found prior to 2020-09-21, the scheduled release date for 3.8.6, no code changes are planned between this release candidate and the final release. That being said, please keep in mind that this is a pre-release and as such its main purpose is testing. Maintenance releases for the 3.8 series will continue at regular bi-monthly intervals, with 3.8.7 planned for mid-November 2020. What’s new? The Python 3.8 series is the newest feature release of the Python language, and it contains many new features and optimizations. See the “What’s New in Python 3.8 <https://docs.python.org/3.8/whatsnew/3.8.html>” document for more information about features included in the 3.8 series. Python 3.8 is becoming more stable. Our bugfix releases are becoming smaller as we progress. This one contains 80 changes, not even a half of what we got in 3.8.4 (the following release was a hotfix). Detailed information about all changes made in version 3.8.6 specifically can be found in its change log <https://docs.python.org/release/3.8.6rc1/whatsnew/changelog.html#python-3-8…>. We hope you enjoy Python 3.8! Thanks to all of the many volunteers who help make Python Development and these releases possible!

[RELEASED] Python 3.5.10 is released
by Larry Hastings 5 সেপ্টেম্বর, 2020

5 সেপ্টেম্বর, 2020

On behalf of the Python development community, I'm plesed to announce the availability of Python 3.5.10. Python 3.5 is in "security fixes only" mode. This new version only contains security fixes, not conventional bug fixes, and it is a source-only release. Important Notice: The latest releases of Linux (Ubuntu 20.04, Fedora 32) ship with a new version of OpenSSL. New versions of OpenSSL often include upgraded configuration requirements to maintain network security; this new version no longer finds Python 3.5's OpenSSL configuration acceptable. As a result, most or all secure-transport networking libraries are broken in this release on systems where this new version of OpenSSL is deployed. This means, for example, that seven (7) of the regression tests in the test suite now regularly fail. Older versions of Linux, with older versions of OpenSSL installed, are unaffected. We're aware of the problem. Unfortunately, as 3.5 is nearly completely out of support, it has become very low priority, and we've been unable to find the resources to get the problem fixed. It's possible that these problems simply won't be fixed in 3.5 before it reaches its end-of-life. As always we recommend upgrading to the latest Python release wherever possible. Python 3.5 will reach its "end of life" at the end of September 2020. If there are no security patches filed for Python 3.5 after the release of Python 3.5.10, then Python 3.5.10 will be the final release of the 3.5 series. You can find Python 3.5.10 here: https://www.python.org/downloads/release/python-3510/ Cheers, //arry/
