Python 3.9.0a2An early developer preview of Python 3.9 is also ready:
https://www.python.org/downloads/release/python-390a2/

Python 3.9 is still in development. This releasee, 3.9.0a2 is the second 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 3.8Many new features for Python 3.9 are still being planned and written. Among the new major new features and changes so far:
PEP 602, Python adopts a stable annual release cadenceBPO 38379, garbage collection does not block on resurrected objects;BPO 38692, os.pidfd_open added that allows process management without races and signals;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.(Hey, fellow core developer, if a feature you find important is missing from this list, let Łukasz know.)

Python 3.8.2rc2 is the second release candidate of the second maintenance release of Python 3.8. Go get it here:
https://www.python.org/downloads/release/python-382rc2/


Why a second release candidate?The major reason for RC2 is that GH-16839 has been reverted.

The original change was supposed to fix for some edge cases in urlparse (numeric paths, recognizing netlocs without //; details in BPO-27657). Unfortunately it broke third parties relying on the pre-existing undefined behavior.

Sadly, the reverted fix has already been released as part of 3.8.1 (and 3.7.6 where it’s also reverted now). As such, even though the revert is itself a bug fix, it is incompatible with the behavior of 3.8.1.

Please test.

TimelineAssuming no critical problems are found prior to 2020-02-24, the currently scheduled release date for  3.8.2 (as well as 3.9.0 alpha 4!), 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 of 3.8.2 and as such its main purpose is testing.

Maintenance releases for the 3.8 series will continue at regular bi-monthly intervals, with 3.8.3 planned for April 2020 (during sprints at PyCon US).

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” document for more information about features included in the 3.8 series.

Detailed information about all changes made in version 3.8.2 specifically can be found in its change log.

A first release candidate for Python 2.7.18 is now available for download. Python 2.7.18 will be the last release of the Python 2.7 series, and thus Python 2.Media Media Media Media MediaMedia

via Python Insider https://ift.tt/2UNNAyI

The CPython core developers are pleased to announce the immediate availability of Python 2.7.18.

Python 2.7.18 is the last Python 2.7
release and therefore the last Python 2 release. It's time for the CPython
community to say a fond but firm farewell to Python 2.

Download this unique, commemorative Python release on python.org.

Python 2.7 has been under active development since the release of Python 2.6,
more than 11 years ago. Over all those years, CPython's core developers and
contributors sedulously applied bug fixes to the 2.7 branch, no small task as
the Python 2 and 3 branches diverged. There were large changes midway through
Python 2.7's life such as PEP 466's feature backports to the ssl module and
hash randomization. Traditionally, these features would never have been added
to a branch in maintenance mode, but exceptions were made to keep Python 2 users
secure. Thank you to CPython's community for such dedication.

Python 2.7 was lucky to have the services of two generations of binary builders
and operating system experts, Martin von Löwis and Steve Dower for Windows, and
Ronald Oussoren and Ned Deily for macOS. The reason we provided binary Python
2.7 releases for macOS 10.9, an operating system obsoleted by Apple 4 years ago,
or why the "Microsoft Visual C++ Compiler for Python 2.7" exists is the
dedication of these individuals.

Python 3 would be nowhere without the dedication of the wider community. Library
maintainers followed CPython by maintaining Python 2 support for many years but
also threw their weight behind the Python 3 statement.
Linux distributors chased Python 2 out of their
archives. Users migrated hundreds of millions of lines of code, developed
porting guides, and kept Python 2 in their brain while Python 3 gained 10 years
of improvements.

Finally, thank you to GvR for creating Python 0.9, 1, 2, and 3.

Long live Python 3+!

On behalf of the PyPA, I am pleased to announce that a new version of pip, pip 20.1, has been released.

To install pip 20.1, you can run:
python -m pip install --upgrade pipThe highlights for this release are:Significant speedups when building local directories, by changing behavior to perform in-place builds, instead of copying to temporary directories.Significant speedups in pip list --outdated, by parallelizing network access. This is the first instance of parallel code within pip's codebase.A new pip cache command, which makes it possible to introspect and manage pip's cache directory.Better pip freeze for packages installed from direct URLs, enabled by the implementation of PEP 610.
This release also contains an alpha version of pip's next generation resolver. It is off by default because it is unstable and not ready for everyday use. If you're curious about this, please visit this GitHub issue about the resolver, what doesn't work yet, and what kind of testing would help us out. We plan to release a version of pip that includes a beta of the new resolver in May.

The full changelog is available.

As with all pip releases, a significant amount of the work was contributed by pip's user community. Huge thanks to all who have contributed, whether through code, documentation, issue reports and/or discussion. Your help keeps pip improving, and is hugely appreciated.

Thank you to the pip and PyPA maintainers, and to all the contributors and volunteers who work on or use Python packaging tools.

And thank you to Mozilla (through its Mozilla Open Source Support Awards) and to the Chan Zuckerberg Initiative DAF, an advised fund of Silicon Valley Community Foundation, for funding enabling work on the new resolver, and thanks to the PSF and the Packaging WG for obtaining and administering that funding.Media Media Media Media MediaMedia

This is a beta preview of Python 3.9Python 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 wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release.

Call to actionWe <b>strongly encourage</b> maintainers of third-party Python projects to <b>test with 3.9</b> during the beta phase and report issues found to <a href="https://bugs.python.org/">the Python bug tracker</a> 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 <b>not</b> recommended for production environments.

Wait, Beta 3? What happened to Beta 2?Beta 2? Speak of him no more. We disappeared him. He was a bad release. Truly awful. I get shivers just thinking about it. Never mention that name again in this house.
I mean, long story short, in Beta 2 you couldn’t do <code>urllib.request.urlopen("https://www.python.org").read()</code> because it wouldn’t find root certificates due to <a href="https://bugs.python.org/issue40924">a bug</a>. Since this was a problem only apparent on an installed Python, it wasn’t identified by unit tests and was only found by Ned while he was testing his Mac installer. By the time we learned of the severity of the bug I already tagged and published the release on <a href="http://python.org/">python.org</a>. That’s why we couldn’t just re-do the release under the same version.
Sorry for the trouble. We’re tweaking our release process to catch this problem sooner in future releases. Now, back to regular programming…

Call to actionWe <b>strongly encourage</b> maintainers of third-party Python projects to <b>test with 3.9</b> during the beta phase and report issues found to <a href="https://bugs.python.org/">the Python bug tracker</a> 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 5 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 <b>not</b> recommended for production environments.
