[RELEASE] Python 3.11 release candidate 2 (3.11.0rc2) is available
by Pablo Galindo Salgado 12 Sep '22

12 Sep '22

Python 3.11 is one month away, can you believe it? This snake is still trying to bite as it has been an interesting day of fighting fires, release blockers, and a bunch of late bugs but your friendly release team always delivers :) You can get this new release while is still fresh here: https://www.python.org/downloads/release/python-3110rc2/ ## This is the second release candidate of Python 3.11 This release, **3.11.0rc2**, is the last preview before the final release of Python 3.11.0 on 2022-10-24. Entering the release candidate phase, only reviewed code changes which are clear bug fixes are allowed between this release candidate and the final release. The second candidate and the last planned release preview is currently planned for Monday, 2022-09-05 while the official release is planned for Monday, 2022-10-24. There will be no ABI changes from this point forward in the 3.11 series and the goal is that there will be as few code changes as possible. ## Modification of the final release Due to the fact that we needed to delay the last release candidate by a week and because of personal scheduling problems I am delaying the final release to 2022-10-24 (three weeks from the original date). ## Call to action ⚠️⚠️⚠️⚠️⚠️⚠️⚠️ The 3.11 branch is now accepting changes for 3.11.**1**. To maximize stability, the final release will be cut from the v3.11.0rc2 tag. If you need the release manager (me) to cherry-pick any critical fixes, mark issues as release blockers, and/or add me as a reviewer on a critical backport PR on GitHub. To see which changes are currently cherry-picked for inclusion in 3.11.0, look at the short-lived branch-v3.11.0 https://github.com/python/cpython/tree/branch-v3.11.0 on GitHub. ⚠️⚠️⚠️⚠️⚠️⚠️⚠️ --- #### Core developers: all eyes on the docs now * Are all your changes properly documented? * Did you notice other changes you know of to have insufficient documentation? #### Community members We strongly encourage maintainers of third-party Python projects to prepare their projects for 3.11 compatibilities during this phase. As always, report any issues to [the Python bug tracker ](https://github.com/issues). Please keep in mind that this is a preview release and its use is **not** recommended for production environments. # Major new features of the 3.11 series, compared to 3.10 Some of the new major new features and changes in Python 3.11 are: ## General changes * [PEP 657](https://www.python.org/dev/peps/pep-0657/) -- Include Fine-Grained Error Locations in Tracebacks * [PEP 654](https://www.python.org/dev/peps/pep-0654/) -- Exception Groups and `except*` * [PEP 680](https://www.python.org/dev/peps/pep-0680/) -- tomllib: Support for Parsing TOML in the Standard Library * [gh-90908](https://github.com/python/cpython/issues/90908) -- Introduce task groups to asyncio * [gh-34627](https://github.com/python/cpython/issues/34627/) -- Atomic grouping (`(?>...)`) and possessive quantifiers (`*+, ++, ?+, {m,n}+`) are now supported in regular expressions. * The [Faster CPython Project](https://github.com/faster-cpython/) is already yielding some exciting results. Python 3.11 is up to 10-60% faster than Python 3.10. On average, we measured a 1.22x speedup on the standard benchmark suite. See [Faster CPython]( https://docs.python.org/3.11/whatsnew/3.11.html#faster-cpython) for details. ## Typing and typing language changes * [PEP 673](https://www.python.org/dev/peps/pep-0673/) -- Self Type * [PEP 646](https://www.python.org/dev/peps/pep-0646/) -- Variadic Generics * [PEP 675](https://www.python.org/dev/peps/pep-0675/) -- Arbitrary Literal String Type * [PEP 655](https://www.python.org/dev/peps/pep-0655/) -- Marking individual TypedDict items as required or potentially-missing * [PEP 681](https://www.python.org/dev/peps/pep-0681/) -- Data Class Transforms <small>(Hey, **fellow core developer,** if a feature you find important is missing from this list, [let Pablo know](mailto:pablogsal@python.org ).)</small> The next release will be the final release of Python 3.11.0, which is currently scheduled for Monday, 2022-10-24. # More resources * [Online Documentation](https://docs.python.org/3.11/) * [PEP 664](https://www.python.org/dev/peps/pep-0664/), 3.11 Release Schedule * Report bugs at [ https://github.com/python/cpython/issues](https://github.com/python/cpython… . * [Help fund Python and its community](/psf/donations/). # And now for something completely different In general relativity, a white hole is a theoretical region of spacetime and singularity that cannot be entered from the outside, although energy-matter, light and information can escape from it. In this sense, it is the reverse of a black hole, which can be entered only from the outside and from which energy-matter, light and information cannot escape. White holes appear in the theory of eternal black holes. In addition to a black hole region in the future, such a solution of the Einstein field equations has a white hole region in its past. This region does not exist for black holes that have formed through gravitational collapse, however, nor are there any observed physical processes through which a white hole could be formed. Supermassive black holes are theoretically predicted to be at the centre of every galaxy and that possibly, a galaxy cannot form without one. Stephen Hawking and others have proposed that these supermassive black holes spawn a supermassive white hole. # We hope you enjoy the new releases!

[RELEASE] Python versions 3.10.7, 3.9.14, 3.8.14, 3.7.14 now available with security content
by Łukasz Langa 07 Sep '22

07 Sep '22

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-bincvenamecgi…>CVE-2020-10735 <https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-10735> Converting between int and str in bases other than 2 (binary), 4, 8 (octal), 16 (hexadecimal), or 32 such as base 10 (decimal) now raises a ValueError <https://docs.python.org/release/3.10.7/whatsnew/3.10.html#notable-security-…> 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. <https://discuss.python.org/#python-3107-2>Python 3.10.7 Get it here: https://www.python.org/downloads/release/python-3107/ <https://www.python.org/downloads/release/python-3107/> 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 <https://docs.python.org/release/3.10.7/whatsnew/changelog.html>. <https://discuss.python.org/#and-now-for-something-completely-different-3>And now for something completely different 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. <https://discuss.python.org/#we-hope-you-enjoy-the-new-releases-4>We hope you enjoy the new releases!

[RELEASE] Python 3.11.0 RC2 is blocked
by Pablo Galindo Salgado 05 Sep '22

05 Sep '22

Hi everyone, Today was the scheduled release of Python 3.11.0 RC2 but unfortunately, we have a bunch of release blockers. Here are some of them: https://github.com/python/cpython/issues/96569 https://github.com/python/cpython/issues/96559 https://github.com/python/cpython/issues/96572 https://github.com/python/cpython/issues/96046 https://github.com/python/cpython/issues/95027 Here is the current GH query: https://github.com/python/cpython/issues?q=is%3Aissue+is%3Aopen+sort%3Aupda… Some of these issues were opened today or yesterday and some others are likely already solved but need someone to confirm that there is nothing left for 3.11. Until these issues are resolved I won't be able to continue with the release of 3.11.0 RC2. Please, also remember that after 3.11.0 RC2 there should not be **any code changes** (ideally, obviously if something major is discovered we will include it in 3.11.0). So if you have any bugfix or similar that you want to get included in 3.11.0 please let me know ASAP otherwise, it will need to wait for 3.11.1. Thank you very much for your help! Regards from cloudy London, Pablo Galindo Salgado
