is announcement here 
<https://discuss.python.org/t/the-python-software-foundation-has-been-authorized-by-the-cve-program-as-a-cve-numbering-authority-cna/32561>.

What this also allows us to do is to combine announcement of CVEs with the 
release of patched versions of Python. This is in fact the case with two of the 
CVEs listed above (CVE-2023-6597 
<https://www.cve.org/CVERecord?id=CVE-2023-6597> and CVE-2024-0450 
<https://www.cve.org/CVERecord?id=CVE-2024-0450>). And since Seth is now 
traveling, this announcement duty was fulfilled by the PSF’s Director of 
Infrastructure @EWDurbin <https://discuss.python.org/u/ewdurbin>. Thanks!

I’m happy to see us successfully testing bus factor resilience on multiple 
fronts with this round of releases.

There’s security content in the releases, let’s dive right in.

gh-108310 <https://github.com/python/cpython/issues/108310>: Fixed an issue
where instances of ssl.SSLSocket

3.11.5

Get it here: https://www.python.org/downloads/release/python-3115/

This release was held up somewhat by the resolution of this CVE, which is why
it includes a whopping 328 new commits since 3.11.4 (compared to 238 commits
between 3.10.4 and 3.10.5). Among those, there is a fix for CVE-2023-41105
<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-41105>which affected
Python 3.11.0 - 3.11.4. See gh-106242
<https://github.com/python/cpython/issues/106242> for details.

There are also some fixes for crashes, check out the change log
<https://docs.python.org/release/3.11.5/whatsnew/changelog.html> to see all

Most importantly, the release notes on the downloads page
<https://www.python.org/downloads/release/python-3115/> include a description
of the Larmor precession. I understood some of the words there!

2022-10-11 Thread Łukasz Langa

Déjà vu? Right, a month after the expedited releases we are doing the dance 
again. This coincides with the regular scheduled time for 3.10.8 but since we 
accrued a few fixes in 3.7 - 3.9 as well, we’re again releasing all four 
editions at the same time. We’re not promising to continue at this pace 😅

As a bugfix release coming a mere month after an out-of-schedule security 
release, 3.10.8 is somewhat smaller compared to 3.9.8 released at the same 
stage of the release cycle a year ago. There’s 151 commits vs 204 in 3.9. It’s 
still a larger release than 3.10.7 at 113 commits. One way or the other, it’s 
worth checking out the change log 
<https://docs.python.org/release/3.10.8/whatsnew/changelog.html>.

Granular convection is a phenomenon where granular material subjected to 
shaking or vibration will exhibit circulation patterns similar to types of 
fluid convection.

It is sometimes described as the Brazil nut effect when the largest particles 
end up on the surface of a granular material containing a mixture of variously 
sized objects; this derives from the example of a typical container of mixed 
nuts, where the largest will be Brazil nuts.

The phenomenon is also known as the muesli effect since it is seen in packets 
of breakfast cereal containing particles of different sizes but similar 
densities, such as muesli mix.

Under experimental conditions, granular convection of variously sized particles 
has been observed forming convection cells similar to fluid motion.

[RELEASE] Python versions 3.10.7, 3.9.14, 3.8.14, 3.7.14 now available with security content

2022-09-07 Thread Łukasz Langa

We have some security content, and plenty of regular bug fixes for 3.10. Let’s 
dive right in.

 
<https://discuss.python.org/#cve-2020-10735httpscvemitreorgcgi-bincvenamecginamecve-2020-10735-1>CVE-2020-10735

Converting between int and str in bases other than 2 (binary), 4, 8 (octal), 16

 if the number of digits in string form is above a limit to avoid potential 
denial of service attacks due to the algorithmic complexity.

Security releases for 3.9.14, 3.8.14, and 3.7.14 are made available 
simultaneously to address this issue, along with some less urgent security 
content.

Upgrading your installations is highly recommended.

This bugfix version of Python was released out-of-schedule to address the CVE, 
and as such contains a smaller number of changes compared to 3.10.6 (200 
commits), or in fact 3.9.7 (187 commits) at the same stage of the release cycle 
a year ago. But there’s still over a 100 commits in this latest Python version 
so it’s worth checking out the change log

In quantum mechanics, the uncertainty principle (also known as Heisenberg’s 
uncertainty principle) is any of a variety of mathematical inequalities 
asserting a fundamental limit to the accuracy with which the values for certain 
pairs of physical quantities of a particle, such as position and momentum or 
the time and the energy can be predicted from initial conditions.

Such variable pairs are known as complementary variables or canonically 
conjugate variables; and, depending on interpretation, the uncertainty 
principle limits to what extent such conjugate properties maintain their 
approximate meaning, as the mathematical framework of quantum physics does not 
support the notion of simultaneously well-defined conjugate properties 
expressed by a single value.

The uncertainty principle implies that it is in general not possible to predict 
the value of a quantity with arbitrary certainty, even if all initial 
conditions are specified.

[RELEASE] Python 3.9.13 is now available

2022-05-17 Thread Łukasz Langa

This is the thirteenth maintenance release of Python 3.9. Get it here:
Python 3.9.13 <https://www.python.org/downloads/release/python-3913/>
According to the release calendar specified in PEP 596 
<https://www.python.org/dev/peps/pep-0596/>, Python 3.9.13 is the final regular 
maintenance release. Starting now, the 3.9 branch will only accept security 
fixes and releases of those will be made in source-only form until October 2025.

This is a milestone moment for me as it means that now both of my release 
series are security-only. My work as release manager enters its final stage. 
I’m not crying, you’re crying! 🥲

Compared to the 3.8 series, this last regular bugfix release is still pretty 
active at 166 commits since 3.9.12. In comparison, version 3.8.10, the final 
regular bugfix release of Python 3.8, included only 92 commits. However, it’s 
likely that it was 3.8 that was special here with the governance changes 
occupying core developers’ minds. For reference, version 3.7.8, the final 
regular bugfix release of Python 3.7, included 187 commits.

In any case, 166 commits is quite a few changes, some of which being pretty 
important fixes. Take a look at the change log 
<https://docs.python.org/release/3.9.13/whatsnew/changelog.html> for details.

[RELEASE] Python 3.10.4 and 3.9.12 are now available out of schedule

2022-03-24 Thread Łukasz Langa

Did anybody say cursed releases 
<https://discuss.python.org/t/python-3-10-3-3-9-11-3-8-13-and-3-7-13-are-now-available-with-security-content/14353>?
 Well, it turns out that 3.10.3 and 3.9.11 both shipped a regression which 
caused those versions not to build on Red Hat Enterprise Linux 6. While this 
11-year-old version is now out of maintenance support 
<https://access.redhat.com/support/policy/updates/errata>, it’s still used in 
production workloads. Some of those rely on Python 3.9 and/or 3.10. In 
particular, our own manylinux2010 
<https://github.com/pypa/manylinux/tree/manylinux2010_x86_64_centos6_no_vsyscall>
 image used to build widely compatible Linux wheels is based on CentOS 6. 
(Don’t worry, we do have newer manylinux* variants, see PEP 599 
<https://peps.python.org/pep-0599/> and PEP 600 
<https://peps.python.org/pep-0600/> for details.)

Due to the out-of-schedule release, the respective versions released today 
contain a very limited set of changes. Python 3.9.12 only contains 12 other bug 
fixes on top of 3.9.11. Python 3.10.4 only contains 10 other bug fixes on top 
of 3.10.3.

Get 3.10.4 here: Python Release 3.10.4 | Python.org 
<https://www.python.org/downloads/release/python-3104>
Get 3.9.12 here: Python Release 3.9.12 | Python.org 
<https://www.python.org/downloads/release/python-3912>
Hopefully, the third time’s a charm and we’ll return no sooner than May with 
the regularly scheduled bug fix releases of 3.9 and 3.10.

. In turn, the 
changes in 3.7.13 
<https://docs.python.org/release/3.7.13/whatsnew/changelog.html> look almost 
identical to the ones in 3.8.13.

 3.6 is pining for the fjords

Python 3.6 is no more. It’s an ex-Python. It has ceased to be. On December 23rd 
2021 is has reached its end-of-life phase 
<https://www.python.org/dev/peps/pep-0494/> after five successful years.

It’s been the first truly popular Python 3 release, introducing f-strings to 
the world and making big improvements to both asyncio (async generators!) and 
typing (variable annotations!).

We’d like to congratulate Ned Deily @nad <https://discuss.python.org/u/nad> on 
successfully driving the 3.6 series to completion as Release Manager. He’s not 
fully retired yet, as 3.7, which he is also managing, is still receiving 
security patches until June 2023.

<https://www.python.org/downloads/release/python-399/>
Python 3.9.9 is the eighth maintenance release of the legacy 3.9 series. Python 
3.10 is now the latest feature release series of Python 3. Get the latest 
release of 3.10.x here <https://python.org/downloads/>.

3.9.9 was released out of schedule as a hotfix for an argparse regression in 
Python 3.9.8 which caused complex command-line tools to fail recognizing 
sub-commands properly. Details in BPO-45235 
<https://bugs.python.org/issue45235>. There are only three other bugfixes in 
this release compared to 3.9.8. See the changelog 
<https://docs.python.org/release/3.9.9/whatsnew/changelog.html> for details on 
what changed.

Upgrading to 3.9.9 is highly recommended if you’re running Python 3.9.8.

The next Python 3.9 maintenance release will be 3.9.10, currently scheduled for 
2022-01-03.

[RELEASE] Python 3.9.8 and 3.11.0a2 are now available

2021-11-05 Thread Łukasz Langa

Tcl/Tk updates

With the recent release of macOS 12 Monterey, we noticed that tkinter file
dialogs are failing to show up on this new operating system, including in our
built-in IDLE. Thanks to rapid help from the Tk team, and Marc Culler in
particular, we were able to fix the issue by bundling Python 3.9.8 and Python
3.11.0a2 with a fixed Tcl/Tk version. In 3.9.8 it’s a patched 8.6.11 release
while 3.11.0a2 is rocking the bleeding-edge 8.6.12rc1.

Since the issue also affected our latest stable version, 3.10.0, an updated
macOS installer for this version was issued. You can recognize it by the post2
version appendix: python-3.10.0post2-macos11.pkg
<https://www.python.org/ftp/python/3.10.0/python-3.10.0post2-macos11.pkg>. We
didn’t have to bump the version number of Python itself since there are no
Python source differences between this package and the original 3.10.0. The
only difference is the bundled patched Tcl/Tk library.

Initially the original 3.10.0 installer was removed from the website after all
URLs got updated to point to the patched version but it turned out this breaks
some workflows
<https://discuss.python.org/t/disappearing-macos-packages-on-python-org/11737>
so the patched installer is now also available under the original filename.

Python 3.9.8 is the seventh maintenance release of the legacy 3.9 series.
Python 3.10 is now the latest feature release series of Python 3. Get the
latest release of 3.10.x here <https://python.org/downloads/>.
There’s been 202 commits since 3.9.7 which shows that there’s still
considerable interest in improving Python 3.9. To compare, at the same stage of
the release cycle Python 3.8 received over 25% fewer commits. See the changelog
<https://docs.python.org/release/3.9.8/whatsnew/changelog.html> for details on
what changed.

On macOS, the default installer is now the new universal2 variant. It’s
compatible with Mac OS X 10.9 and newer, including macOS 11 Big Sur and macOS
12 Monterey. You may need to upgrade third-party components, like pip, to the
newest versions. You may experience differences in behavior in IDLE and other
Tk-based applications due to using the newest version of Tk. As always, if you
encounter problems when using this installer variant, please check
https://bugs.python.org <https://bugs.python.org/> for existing reports and for
opening new issues.

The next Python 3.9 maintenance release will be 3.9.9, currently scheduled for
2022-01-03.

Python 3.11 is still in development. This release, 3.11.0a2 is the second of
seven 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 (2022-05-06) and, if necessary, may be modified or deleted up until the
release candidate phase (2022-08-01). Please keep in mind that this is a
preview release and its use is not recommended for production environments.

Many new features for Python 3.11 are still being planned and written. Among
the new major new features and changes so far:

PEP 657 <https://www.python.org/dev/peps/pep-0657/> – Include Fine-Grained
Error Locations in Tracebacks
The Faster CPython Project 1 <https://github.com/faster-cpython> is already
yielding some exciting results: this version of CPython 3.11 is ~12% faster on
the geometric mean of the PyPerformance benchmarks <>, compared to 3.10.0.
(Hey, fellow core developer, if a feature you find important is missing from
this list, let Pablo know <mailto:pablog...@python.org>.)
The next pre-release of Python 3.11 will be 3.11.0a3, currently scheduled for
Monday, 2021-12-06.

Python 3.9.7

Get it here: https://www.python.org/downloads/release/python-397/
<https://www.python.org/downloads/release/python-397/>
Python 3.9.7 is the newest major stable release of the Python programming
language, and it contains many new features and optimizations. There’s been 187
commits since 3.9.6 which is a similar amount compared to 3.8 at the same stage
of the release cycle. See the change log
<https://docs.python.org/release/3.9.7/whatsnew/changelog.html> for details.

On macOS, we encourage you to use the universal2 binary installer variant
whenever possible. The legacy 10.9+ Intel-only variant will not be provided for
Python 3.10 and the universal2 variant will become the default download for
3.9.8. You may need to upgrade third-party components, like pip, to later
versions. You may experience differences in behavior in IDLE and other Tk-based
applications due to using the newer version of Tk. As always, if you encounter

Second Security-Only Release of Python 3.8

Get it here: https://www.python.org/downloads/release/python-3812/
<https://www.python.org/downloads/release/python-3812/>
Security content in this release contains four fixes. There are also four
additional fixes for bugs that might have lead to denial-of-service attacks.
Finally, while we’re not providing binary installers anymore, for those users
who produce installers, we upgraded the OpenSSL version used to 1.1.1l. Take a
look at the change log
<https://docs.python.org/release/3.8.12/whatsnew/changelog.html> for details.

According to the release calendar specified in PEP 569
<https://www.python.org/dev/peps/pep-0569/>, Python 3.8 is now in “security
fixes only” stage of its life cycle: 3.8 branch only accepts security fixes and
releases of those are made irregularly in source-only form until October 2024.
Python 3.8 isn’t receiving regular bug fixes anymore, and binary installers are
no longer provided for it. Python 3.8.10 was the last full bugfix release of
Python 3.8 with binary installers.

[RELEASE] Python 3.8.10, 3.9.5, and 3.10.0b1 are now available

2021-05-03 Thread Łukasz Langa

This has been a very busy day for releases and on behalf of the Python
development community we’re happy to announce the availability of three new
Python releases.

Python 3.10 is now in Beta

Get it here: Python 3.10.0b1
<https://www.python.org/downloads/release/python-3100b1/>
Python 3.10 is still in development. 3.10.0b1 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.

We strongly encourage maintainers of third-party Python projects to test with
3.10 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 (Monday, 2021-08-02). Our goal is have no ABI changes after
beta 4 and as few code changes as possible after 3.10.0rc1, the first release
candidate. To achieve that, it will be extremely important to get as much
exposure for 3.10 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.

The next pre-release, the second beta release of Python 3.10, will be 3.10.0b2.
It is currently scheduled for 2021-05-25. Please see PEP 619
<https://www.python.org/dev/peps/pep-0619/> for details.

Development Begins on Python 3.11

With Python 3.10 moving to beta, it received its own 3.10 branch in the
repository <https://github.com/python/cpython/>. All new features are now
targeting Python 3.11, to be released in October 2022.

Using the opportunity with the creation of the 3.10 branch, we renamed the
master branch of the repository to main. It’s been a bit rocky
<https://github.community/t/renaming-python-master-branch-to-main-1-4k-prs-700-repositories-triggered-server-http-error-500/178090>
but looks like we’re open for business. Please rename the main branch of your
personal fork using the guide GitHub will give you when you go to your fork’s
main page. In case of any outstanding issues, please contact the 3.11 RM
<https://devguide.python.org/devcycle/#current-administrators>.

Python 3.9.5

Get it here: Python 3.9.5 <https://www.python.org/downloads/release/python-395/>
Python 3.9.5 is the newest major stable release of the Python programming
language, and it contains many new features and optimizations. There’s been 111
commits since 3.9.4 which is a similar amount compared to 3.8 at the same stage
of the release cycle. See the change log
<https://docs.python.org/release/3.9.5/whatsnew/changelog.html> for details.

On macOS, we encourage you to use the universal2 variant whenever possible. The
legacy 10.9+ Intel-only variant will not be provided for Python 3.10 and the
universal2 variant will become the default download for future 3.9.x releases.
You may need to upgrade third-party components, like pip, to later versions
once they are released. You may experience differences in behavior in IDLE and
other Tk-based applications due to using the newer version of Tk. As always, if
you encounter problems when using this installer variant, please check
https://bugs.python.org <https://bugs.python.org/> for existing reports and for
opening new issues.

The next Python 3.9 maintenance release will be 3.9.6, currently scheduled for
2021-06-28.

The Last Regular Bugfix Release of Python 3.8

Get it here: Python 3.8.10
<https://www.python.org/downloads/release/python-3810/>
According to the release calendar specified in PEP 569
<https://www.python.org/dev/peps/pep-0569/>, Python 3.8.10 is the final regular
maintenance release. Starting now, the 3.8 branch will only accept security
fixes and releases of those will be made in source-only form until October
2024. To keep receiving regular bug fixes, please upgrade to Python 3.9.

Compared to the 3.7 series, this last regular bugfix release is relatively
dormant at 92 commits since 3.8.9. Version 3.7.8, the final regular bugfix
release of Python 3.7, included 187 commits. But there’s a bunch of important
updates here regardless, the biggest being macOS Big Sur and Apple Silicon
build support. This work would not have been possible without the effort of
Ronald Oussoren, Ned Deily, Maxime Bélanger, and Lawrence D’Anna from Apple.
Thank you!

Take a look at the change log
<https://docs.python.org/release/3.8.10/whatsnew/changelog.html> for details.

We hope you enjoy the new releases

[RELEASE] Python 3.9.4 hotfix is now available

2021-04-04 Thread Łukasz Langa

Python 3.9.3 was released two days ago on Friday, April 2nd. It contains
important security content listed below for reference. Unfortunately, it also
introduced an unintentional ABI incompatibility, making some C extensions built
with Python 3.9.0 - 3.9.2 crash with Python 3.9.3 on 32-bit systems. To
minimize disruption, I decided to recall 3.9.3 and introduce this hotfix
release: 3.9.4.

We highly recommend upgrading your Python 3.9 installations to 3.9.4 at your
earliest convenience.

Get it here:

https://www.python.org/downloads/release/python-394/
<https://www.python.org/downloads/release/python-394/>
What is “ABI compatibility”?

Python guarantees that within a given language series (like the current 3.9)
binary extensions written in C or C++ and compiled against headers of one
release (like 3.9.0) will be importable from other versions in the same series
(like 3.9.3). If this weren’t the case, library authors would have to ship
separate binary wheels on PyPI for every single bugfix release of Python. That
would be very inconvenient.

<https://discuss.python.org/t/python-3-9-4-hotfix-is-now-available/8056#what-broke-in-python-393>What
broke in Python 3.9.3?

In a fix for a corner-case crash around recursion limits and exceptions, the
PyThreadState struct needed to change. While PyThreadState’s only documented
public member is the *interp field
<https://docs.python.org/3.9/c-api/init.html#c.PyThreadState>, it’s not
uncommon for C extensions to access other fields in this struct as well.

When I approved the backport of this fix, I missed the fact that the variable
size change would change the memory layout of said struct on 32-bit systems (on
64-bit systems alignment rules made the size change backwards compatible).
Merging the backport was a mistake, and so 3.9.4 reverts it to restore
compatibility with binary extensions built against Python 3.9.0 - 3.9.2.
Details in bpo-43710 <https://bugs.python.org/issue43710>.

bpo-42988 <https://bugs.python.org/issue42988>: CVE-2021-3426: Remove the

reported by David Schwörer.

the former vulnerable behavior may set a trust_server_pasv_ipv4_address

Calendar

Due to the security fixes, those releases are made a month sooner than planned.
I decided to keep the release calendar intact, meaning that the last full
regular maintenance release of Python 3.8 is still planned for May 3rd 2021,
after which it will shift to source releases only for security bug fixes only.
Maintenance releases for the 3.9 series will continue at regular bi-monthly
intervals, with 3.9.3 planned for May 3rd 2021 as well.

[RELEASE] Python 3.9.2 and 3.8.8 are now available

2021-02-19 Thread Łukasz Langa

Convinced of the wonders of free two-day deliveries, I’m pleased to present you
Python 3.9.2 and 3.8.8. Get them from:

https://www.python.org/downloads/release/python-392/
<https://www.python.org/downloads/release/python-392/>

https://www.python.org/downloads/release/python-388/
<https://www.python.org/downloads/release/python-388/>

Next up, the last full regular maintenance release of Python 3.8 is planned for
May 3rd 2021, after which it will shift to source releases only for security
bug fixes only. Maintenance releases for the 3.9 series will continue at
regular bi-monthly intervals, with 3.9.3 planned for early May 2021.

Why the expedited final release?

This release, just as the candidate before it, contains two security fixes:

bpo-42938 <https://bugs.python.org/issue42938>: Avoid static buffers when
computing the repr of ctypes.c_double and ctypes.c_longdouble values. This
issue was assigned CVE-2021-3177
<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-3177>.

bpo-42967 <https://bugs.python.org/issue42967>: Fix web cache poisoning
vulnerability by defaulting the query args separator to &, and allowing the
user to choose a custom separator. This issue was assigned CVE-2021-23336
<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-23336>.

Since the announcement of the release candidates for 3.9.2 on 3.8.8, we
received a number of inquiries from end users urging us to expedite the final
releases due to the security content, especially CVE-2021-3177
<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-3177>.

This took us somewhat by surprise since we believed security content is
cherry-picked by downstream distributors from source either way, and the RC
releases provide installers for everybody else interested in upgrading in the
meantime. It turns out that release candidates are mostly invisible to the
community and in many cases cannot be used due to upgrade processes which users
have in place.

In turn, the other active release managers and I decided to stop providing
release candidates for bugfix versions. Starting from now on after the initial
3.x.0 final release, all subsequent releases are going to be provided as is in
bi-monthly intervals. The release calendar PEPs for 3.8 and 3.9 have been
updated accordingly.

On the severity of CVE-2021-3177

We recommend you upgrade your systems to Python 3.8.8 or 3.9.2.

Our understanding is that while the CVE is listed as “remote code execution”,
practical exploits of this vulnerability as such are very unlikely due the
following conditions needing to be met for successful RCE:

pass an untrusted floating point number from a remote party to
ctypes.c_double.from_param (note: Python floating point numbers were not
affected);

have that object be passed to repr() (for instance through logging);

have that float point number be valid machine code;

have the buffer overflow overwrite the stack at exactly the right place for the
code to get executed.

In fact, Red Hat’s evaluation of the vulnerability was consistent with ours.
They write: “the highest threat from this vulnerability is to system
availability <https://access.redhat.com/security/cve/cve-2021-3177>.”

To be sure, denial of service through malicious input is also a serious issue.
Thus, to help the community members for whom the release candidate was
insufficient, we are releasing the final versions of 3.9.2 and 3.8.8 today.

What’s new?

The Python 3.9 series contains many new features and optimizations over 3.8.
See the “What’s New in Python 3.9 2
<https://docs.python.org/3.9/whatsnew/3.9.html>” document for more information
about features included in the 3.9 series. We also have a detailed change log
for 3.9.2rc1
<https://docs.python.org/release/3.9.2/whatsnew/changelog.html#python-3-9-2-release-candidate-1>
specifically. The final release only contains a single bugfix
<https://github.com/python/cpython/pull/24554> over the release candidate.

Detailed information about all changes made in version 3.8.8rc1 specifically
can be found in its respective changelog
<https://docs.python.org/release/3.8.8/whatsnew/changelog.html#python-3-8-8-release-candidate-1>.
The final version contains no changes over the release candidate.

We hope you enjoy those new releases!

[RELEASE] Python 3.8.7 is now available

2020-12-21 Thread Łukasz Langa

Python 3.8.7 is the seventh maintenance release of Python 3.8. Go get it here:

https://www.python.org/downloads/release/python-387/ 
<https://www.python.org/downloads/release/python-387/>
Note: this is a bugfix release for the 3.8 series which was superseded by 
Python 3.9, currently the latest feature release series of Python 3. You can 
find the latest release of 3.9.x here <https://www.python.org/downloads/>.

Maintenance releases for the 3.8 series will continue at regular bi-monthly 
intervals, with 3.8.8 planned for February 2021.

macOS 11 Big Sur not fully supported

Python 3.8.7 is not yet fully supported on macOS 11 Big Sur. It will install on 
macOS 11 Big Sur and will run on Apple Silicon Macs using Rosetta 2 
translation. However, a few features do not work correctly, most noticeably 
those involving searching for system libraries (vs user libraries) such as 
ctypes.util.find_library() and in Distutils. This limitation affects both Apple 
Silicon and Intel processors. We are looking into improving the situation for 
Python 3.8.8.

Python 3.9.1 <https://www.python.org/downloads/release/python-391/> provides 
full support for Big Sur and Apple Silicon Macs, including building natively on 
Apple Silicon Macs and support for universal2 binaries.

What’s new?

The Python 3.8 series contains many new features and optimizations over 3.7. 
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.

Detailed information about all changes made in version 3.8.7 specifically can 
be found in its change log 
<https://docs.python.org/release/3.8.7/whatsnew/changelog.html#python-3-8-7>. 
Note that compared to 3.8.6 this release also contains all changes present in 
3.8.7rc1.

We hope you enjoy Python 3.8!

[RELEASE] Python 3.9.1rc1 is now ready for testing

2020-11-26 Thread Łukasz Langa

Python 3.9.1rc1 is the release candidate of the first maintenance release of 
Python 3.9. Go get it here:
https://www.python.org/downloads/release/python-391rc1/ 
<https://www.python.org/downloads/release/python-391rc1/>
Assuming no critical problems are found prior to 2020-12-11, the currently 
scheduled release date for 3.9.1, 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 3.9.1 and as such its main purpose is testing.

Maintenance releases for the 3.9 series will continue at regular bi-monthly 
intervals, with 3.9.2 planned for end of January 2021.

Installer news

3.9.1rc1 is the first version of Python to support macOS 11 Big Sur. With Xcode 
11 and later it is now possible to build “Universal 2” binaries which work on 
Apple Silicon. We are providing such an installer as the macosx11.0 variant. 
This installer can be deployed back to older versions, tested down to OS X 
10.9. As we are waiting for an updated version of pip, please consider the 
macosx11.0 installer experimental.

This work would not have been possible without the effort of Ronald Oussoren, 
Ned Deily, and Lawrence D’Anna from Apple. Thank you!

In other 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.

What’s new in Python 3.9.1rc1?

We’ve made 240 changes since v3.9.0 which is a significant amount. To compare, 
3.8.1rc1 only saw 168 commits since 3.8.0. See the full change log at

https://docs.python.org/release/3.9.1rc1/whatsnew/changelog.html 
<https://docs.python.org/release/3.9.1rc1/whatsnew/changelog.html>.

For more information about features included in the 3.9 series, see the “What’s 
New in Python 3.9 <https://docs.python.org/release/3.9.0/whatsnew/3.9.html>” 
document.

What about Python 3.8.7rc1?

There’s additional work needed to make this release support macOS 11 Big Sur. 
This should be ready next week, stay tuned.

We hope you enjoy the new releases!

[RELEASE] Python 3.9.0 is now available, and you can already test 3.10.0a1!

2020-10-05 Thread Łukasz Langa

On behalf of the Python development community and the Python 3.9 release team, 
I’m pleased to announce the availability of Python 3.9.0.

Python 3.9.0 is the newest feature release of the Python language, and it 
contains many new features and optimizations. You can find Python 3.9.0 here:

https://www.python.org/downloads/release/python-390/ 
<https://www.python.org/downloads/release/python-390/>

Most third-party distributors of Python should be making 3.9.0 packages 
available soon.

See the “What’s New in Python 3.9 
<https://docs.python.org/release/3.9.0/whatsnew/3.9.html>” document for more 
information about features included in the 3.9 series. Detailed information 
about all changes made in 3.9.0 can be found in its change log 
<https://docs.python.org/release/3.9.0/whatsnew/changelog.html#changelog>.

Maintenance releases for the 3.9 series will follow at regular bi-monthly 
intervals starting in late November of 2020.



OK, boring! Where is Python 4?

Not so fast! The next release after 3.9 will be 3.10. It will be an incremental 
improvement over 3.9, just as 3.9 was over 3.8, and so on.

In fact, our newest Release Manager, Pablo Galindo Salgado, prepared the first 
alpha release of what will become 3.10.0 a year from now. You can check it out 
here:

In Standard Collections
 * PEP 593 , Flexible function and 
variable annotations
 * PEP 602 , Python adopts a stable 
annual release cadence
 * PEP 615 , Support for the IANA 
Time Zone Database in the Standard Library
 * PEP 616 , String methods to 
remove prefixes and suffixes
 * PEP 617 , New PEG parser for 
CPython
 * BPO 38379 , garbage collection does not 
block on resurrected objects;
 * BPO 38692 , os.pidfd_open added that 
allows process management without races and signals;
 * BPO 39926 , Unicode support updated to 
version 13.0.0;
 * BPO 1635741 , 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  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 
;
 * 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 .

[RELEASE] Python 3.9.0b4 is now ready for testing

2020-07-03 Thread Łukasz Langa

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 3.9.0b4. Get it here:

https://www.python.org/downloads/release/python-390b4/ 
<https://www.python.org/downloads/release/python-390b4/>

This is a beta preview of Python 3.9

Python 3.9 is still in development. This release, 3.9.0b4, is the fourth of 
five 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 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 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 not 
recommended for production environments.

[RELEASE] Python 3.9.0b3 is now available for testing

2020-06-09 Thread Łukasz Langa

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 3.9.0b3. Get it here:

https://www.python.org/downloads/release/python-390b3/ 
<https://www.python.org/downloads/release/python-390b3/>
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 
urllib.request.urlopen("https://www.python.org";).read() because it wouldn’t 
find root certificates due to a bug <https://bugs.python.org/issue40924>. 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 python.org <http://python.org/>. 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…

Python 3.8.2 and 3.9.0a4 are now available

2020-02-25 Thread Łukasz Langa

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 two 
of the latest Python editions.

Python 3.8.2

Python 3.8.2 is the second maintenance release of Python 3.8 and contains two 
months worth of bug fixes. Detailed information about all changes made in 3.8.2 
can be found in its change log 
<https://docs.python.org/release/3.8.2/whatsnew/changelog.html#python-3-8-2-final>.
 Note that compared to 3.8.1, version 3.8.2 also contains the changes 
introduced in 3.8.2rc1 and 3.8.2rc2.

The Python 3.8 series is the newest feature release of the Python language, and 
it contains many new features and optimizations. You can find Python 3.8.2 here:
https://www.python.org/downloads/release/python-382/ 
<https://www.python.org/downloads/release/python-382/>
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.

Maintenance releases for the 3.8 series will continue at regular bi-monthly 
intervals, with 3.8.3 planned for April 2020 (at the PyCon US sprints 
<https://us.pycon.org/2020/events/sprints/>).

Python 3.9.0a4

An early developer preview of Python 3.9 is also ready:
https://www.python.org/downloads/release/python-390a4/ 
<https://www.python.org/downloads/release/python-390a4/>
Python 3.9 is still in development. This releasee, 3.9.0a4 is the fourth of six

[RELEASE] Python 3.8.2rc2 is now available for testing

2020-02-18 Thread Łukasz Langa

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.


Timeline

Assuming 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 
.


We hope you enjoy Python 3.8!

[RELEASE] ACTION REQUIRED: Python 3.8.0b4 now available for testing

2019-08-30 Thread Łukasz Langa

It's time for the last beta release of Python 3.8. Go find it at:

https://www.python.org/downloads/release/python-380b4/ 



This release is the last 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. The next pre-release of Python 3.8 will be 3.8.0c1, the first release 
candidate, currently scheduled for 2019-09-30.

Call to action

We strongly encourage maintainers of third-party Python projects to test with 
3.8 during the beta phase and report issues found to the Python bug tracker as 
soon as possible. Please note this is the last beta release, there is not much 
time left to identify and fix issues before the release of 3.8.0. If you were 
hesitating trying it out before, now is the time.

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 (2019-09-30). Our goal is have no ABI 
changes after beta 3 and no code changes after 3.8.0c1, the release candidate.

To achieve that, it will be extremely important to get as much exposure for 3.8 
as possible during the beta phase. That beta phase is coming to an end. Please 
test now.

Please keep in mind that this is a preview release and its use is not 
recommended for production environments.

Acknowledgments

Many developers worked hard for the past four weeks to squash remaining bugs, 
some requiring non-obvious decisions. Many thanks to the most active, namely 
Raymond Hettinger, Steve Dower, Victor Stinner, Terry Jan Reedy, Serhiy 
Storchaka, Pablo Galindo Salgado, Tal Einat, Zackery Spytz, Ronald Oussoren, 
Neil Schemenauer, Inada Naoki, Christian Heimes, and Andrew Svetlov.

3.8.0 would not reach the Last Beta without you. Thank you!

release, currently scheduled for 2019-08-26.

Call to action

We strongly encourage maintainers of third-party Python projects to test with 
3.8 during the beta phase and report issues found to the Python bug tracker 
 as soon as possible. While the release is planned to 
be feature complete entering the beta phase, it is possible that features may

Please keep in mind that this is a preview release and its use is not 
recommended for production environments.

Last beta coming

Beta 4 can only be released if all “Release blocker” and “Deferred blocker” 
issues on bugs.python.org  for 3.8.0 are resolved. 
Please prioritize those for the next four weeks.

Acknowledgements

Thanks to our binary builders, Ned and Steve, who were very quick today to get 
the macOS and Windows installers ready. The Windows story in particular got 
pretty magical, it’s now really fully automatic end-to-end.

Thanks to Victor for vastly improving the reliability of multiprocessing tests 
since Beta 2.

Thanks to Pablo for keeping the buildbots green.

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 (2019-09-30). Our goal is have no ABI changes after beta 3 and 
no code changes after 3.8.0rc1, the release candidate. To achieve that, it will 
be extremely important to get as much exposure for 3.8 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.

No more non-bugfixes allowed on the “3.8” branch

The time has come, team. Please help make Python 3.8 as stable as possible and 
keep all features not currently landed for Python 3.9. Don’t fret, it’ll come 
faster than you think.

[RELEASE] Python 3.8.0b1 is now available for testing

2019-06-04 Thread Łukasz Langa

The time has come for Python 3.8.0b1:
https://www.python.org/downloads/release/python-380b1/ 

This release 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. The next pre-release of Python 3.8 will be 3.8.0b2, currently 
scheduled for 2019-07-01.


Call to action

We strongly encourage maintainers of third-party Python projects to test with 
3.8 during the beta phase and report issues found to the Python bug tracker 
 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 (2019-09-30). Our goal is have no ABI changes after beta 3 and 
no code changes after 3.8.0rc1, the release candidate. To achieve that, it will 
be extremely important to get as much exposure for 3.8 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.


A new challenger has appeared!

With the release of Python 3.8.0b1, development started on Python 3.9. The 
“master” branch in the cpython repository now tracks development of 3.9 while 
Python 3.8 received its own branch, called simply “3.8”.


Acknowledgments

As you might expect, creating new branches triggers a lot of changes in 
configuration for all sorts of tooling that we’re using. Additionally, the 
inevitable deadline for new features caused a flurry of activity that tested 
the buildbots to the max. The revert hammer got  used more than once.

I would not be able to make this release available alone. Many thanks to the 
fearless duo of Pablo Galindo Salgado and Victor Stinner for spending tens of 
hours during the past week working on getting the buildbots green for release. 
Seriously, that took a lot of effort. We are all so lucky to have you both.

Thanks to Andrew Svetlov for his swift fixes to asyncio and to Yury Selivanov 
for code reviews, even when jetlagged. Thanks to Julien Palard for untangling 
the documentation configs. Thank you to Zachary Ware for help with buildbot and 
CI configuration. Thanks to Mariatta for helping with the bots. Thank you to 
Steve Dower for delivering the Windows installers.

Most importantly though, huge thanks to Ned Deily who not only helped me 
understand the scope of this special release but also did some of the grunt 
work involved.

Last but not least, thanks to you for making this release more meaty than I 
expected. There’s plenty of super exciting changes in there. Just take a look 
at “What’s New ”!


One more thing

Hey, fellow Core Developer, Beta 2 is in four weeks. If your important new 
feature got reverted last minute, or you decided not to merge due to inadequate 
time, I have a one time offer for you (restrictions apply). If you:

find a second core developer champion for your change; and
in tandem you finish your change complete with tests and documentation before 
Beta 2
then I will let it in. I’m asking for a champion because it’s too late now for 
changes with hasty design or code review. And as I said, restrictions apply. 
For instance, at this point changes to existing APIs are unlikely to be 
accepted. Don’t start new work with 3.8 in mind. 3.9 is going to come sooner 
than you think!

[RELEASE] Python 3.8.0a4 is now available for testing

2019-05-07 Thread Łukasz Langa

It's time for the LAST alpha of Python 3.8.0. Go get it here:
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.

I packaged another release. Go get it here:
https://www.python.org/downloads/release/python-380a2/

Python 3.8.0a2 is the second of four planned alpha releases 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 next preview release, 3.8.0a3, is planned
for 2019-03-25.

This time around the stable buildbots were a bit less green than they should 
have. This early in the cycle, I didn't postpone the release and I didn't use 
the revert hammer. But soon enough, I will. Let's make sure future changes keep 
the buildbots happy.

Apart from building the Mac installers, Ned helped me a lot with the
process, thank you!  Ernest was super quick providing me with all
required access and fixing a Unicode problem I found in Salt,
thank you!

Finally, this release was made on a train to Düsseldorf. There's a PyPy
sprint there. The train is pretty cool, makes this "Wasm! Wasm!" sound.

The Python Papers look very, very promising! I'm looking forward to 
reading next editions. Don't let whiners slow you down. PDF is a good 
choice, I personally like to print out longer things I read. IANAL, so I 
won't speak for or against CC licenses. They're used widely nowadays for 
a variety of applications (music, art, software, publications) so it 
seems they're doing their job.

Keep up the good work!

Re: How can I speed this function up?

2006-11-17 Thread Łukasz Langa

   Hi, Chris.
   I made a trivial testing framework for this cute problem and tried a 
couple of modifications. I also added the 10% of non-ELEMENT lines you 
mentioned. First thing, your updated algorithm didn't really get me much 
faster results than the original. I guess that my disk array sort of 
hides the multiple write penalty. But I experimented with various 
algorithms. Here's the code in its entirety: 
http://www.rafb.net/paste/results/ZuW4fK85.html My results (Python 2.4, 
32bit Fedora Core) were:

[EMAIL PROTECTED] tmp]# python test.py
Preparing data...
[write_data1] Preparing output file...
[write_data1] Writing...
[write_data1] Done in 10.73 seconds.
[write_data4] Preparing output file...

[write_data_once] Preparing output file...

[write_data_once] Done in 7.82 seconds.

   I'm pretty sure that your measures will vary (observing your results 
you seem to have a faster CPU but slower disk(s)). But you can just take 
what works best for you. I'm also quite confident that you won't be able 
to catch up C since as you can see Python's data structures are far more 
flexible and thus require more processing overhead.

   Regards,
   Łukasz

This returns in 0.4 seconds. If I time it to do 50 tests, it returns 
after 20.2 - 20.5 seconds. Even if I substitute the for i in xrange() 
construct to your sh-like while statement. And all that through a 
network, with print statements intact. Guess your true Unix box has some 
features unavailable on Fedora Core or MacOS X ;-)

>   

1.5.2? Come on, it's 7 years old. Back then PHP was still at 3.0, Java 
was at 1.2 (and compiling Hello World took over 5 minutes), Google was 
nothing more than a search engine (still Beta at the time!).

What do we have all these cool new language features for if it's 
considered bad behaviour to actually use them?

OK, I see the point in being compatible with Python 2.1 (well, maybe 2.2 
with new-style classes and __descriptors__), just like it's still useful 
to be Java 1.4 compatible and PHP 4 compatible.

But Python 1.5.2? From the official site: "*Do yourself a favor* and get 
a more recent version!" ;-) It doesn't even have string methods. Today 
Python 1.5.2 is being implemented on one-chip GSM modules ( 
http://www.telit.co.it/product.asp?productId=96 ). And yes, it actually 
works quite well there :-)
