[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 (Hey, **fellow core developer,** if a feature you find important is missing from this list, [let Pablo know](mailto:pablogsal@python.org ).)

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

Some massive stars collapse to form neutron stars at the end of their life cycle, as has been both observed and explained theoretically. Under the extreme temperatures and pressures inside neutron stars, the neutrons are normally kept apart by degeneracy pressure, stabilizing the star and hindering further gravitational collapse. However, it is hypothesized that under even more extreme temperature and pressure, the degeneracy pressure of the neutrons is overcome, and the neutrons are forced to merge and dissolve into their constituent quarks, creating an ultra-dense phase of quark matter based on densely packed quarks. In this state, a new equilibrium is supposed to emerge, as a new degeneracy pressure between the quarks, as well as repulsive electromagnetic forces, will occur and hinder total gravitational collapse. If these ideas are correct, quark stars might occur, and be observable, somewhere in the universe. Theoretically, such a scenario is seen as scientifically plausible, but it has been impossible to prove both observationally and experimentally because the very extreme conditions needed for stabilizing quark matter cannot be created in any laboratory nor observed directly in nature. The stability of quark matter, and hence the existence of quark stars, is for these reasons among the unsolved problems in physics. # We hope you enjoy the new releases!

As quarks have a baryon number of (+1/3), and antiquarks of (−1/3), the pentaquark would have a total baryon number of 1 and thus would be a baryon. Further, because it has five quarks instead of the usual three found in regular baryons (a.k.a. 'triquarks'), it is classified as an exotic baryon. The name pentaquark was coined by Claude Gignoux et al. (1987) and Harry J. Lipkin in 1987; however, the possibility of five-quark particles was identified as early as 1964 when Murray Gell-Mann first postulated the existence of quarks. Although predicted for decades, pentaquarks proved surprisingly tricky to discover and some physicists were beginning to suspect that an unknown law of nature prevented their production. # We hope you enjoy the new releases!

[RELEASE] The last 3.11 beta release (3.11.0b5) is now available
by Pablo Galindo Salgado 26 Jul '22

26 Jul '22

Here we are. The universe. The vastness of spacetime. At the edge. The last frontier. The last beta*(conditions apply) for Python 3.11. We have defied the powerful gods of release blockers and we have won by using the required amount of ruse and subterfuge. https://www.python.org/downloads/release/python-3110b5/ ## :warning: PLEASE HELP US TO TEST THIS RELEASE :warning: Due to the modified release schedule and the stability concerns regarding the past beta releases, please, please, please, please, help us to test Python 3.11 by testing this beta releases. * if you maintain a library or a third-party package. Test the beta releases! * If you have code that you maintain at work/research centre/classroom/whatever. Test the beta releases! * If you are a multi-million corporation that uses Python. Test the beta releases! * If you are a single-person company that uses Python. Test the beta releases! * If you have a bunch of Python scripts. Test the beta releases! * If you use Python for work, research, teaching or literally for anything. Test the beta releases! * If you ... In summary: no matter who you are of what you do. Test the beta releases! Is **very** important for us that we identify all possible things that may break your code **before** the final release is done and we can only do this if you help us by testing the beta releases and then report anything that doesn't work! ## This is a beta preview of Python 3.11 Python 3.11 is still in development. 3.11.0b5 is the last 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. We **strongly encourage** maintainers of third-party Python projects to **test with 3.11** during the beta phase and report issues found to [the Python bug tracker](https://github.com/python/cpython/issues) 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 5 and as few code changes as possible after 3.11.0rc1, the first release candidate. To achieve that, it will be **extremely important** to get as much exposure for 3.11 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. # 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 * [PEP 681](https://www.python.org/dev/peps/pep-0681/)-- Data Class Transforms * [bpo-46752](https://github.com/python/cpython/issues/90908)-- Introduce task groups to asyncio * [bpo-433030](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.

Here, "maximally extended" refers to the idea that spacetime should not have any "edges": it should be possible to continue this path arbitrarily far into the particle's future or past for any possible trajectory of a free-falling particle (following a geodesic in the spacetime). The Einstein–Rosen bridge was discovered by Ludwig Flamm in 1916, a few months after Schwarzschild published his solution, and was rediscovered by Albert Einstein and his colleague Nathan Rosen, who published their result in 1935. However, in 1962, John Archibald Wheeler and Robert W. Fuller published a paper showing that this type of wormhole is unstable if it connects two parts of the same universe and that it will pinch off too quickly for light (or any particle moving slower than light) that falls in from one exterior region to make it to the other exterior region. Although Schwarzschild wormholes are not traversable in both directions, their existence inspired Kip Thorne to imagine traversable wormholes created by holding the "throat" of a Schwarzschild wormhole open with exotic matter (material that has negative mass/energy). # Release hashes The BSD-style checksum hashes for the release artefacts are: SHA256 (python-3.11.0b5-amd64.exe) = 0cf9d582da862f2fe207fd54b81dfca110e8f04f4b05ab8c3228ce1ea060c7af SHA256 (python-3.11.0b5-arm64.exe) = a71efd9d3835d493d8207a30916ce3417af17295c02a9b0783dc740754f6e40b SHA256 (python-3.11.0b5-embed-amd64.zip) = 5584ddbd21f45ce74ce0512eeb1d817d15374b1b7a461d79f973f6dd48ab5d9e SHA256 (python-3.11.0b5-embed-arm64.zip) = 819924f10eb08ea6322b6040a2fb953137866bb1034cd4e8fe6e93c7c0b37e31 SHA256 (python-3.11.0b5-embed-win32.zip) = 18927604bcbe3c226be7864cde0c1f25ad35c6333d9d3125dfff8ca4fc872255 SHA256 (python-3.11.0b5.exe) = 382eb4c6dc1606bd3cf6f4bdeec8e1e7dab444c5aa23b86142d608a480d7c195 SHA256 (python-3.11.0b5-macos11.pkg) = cd8e6d98e79a4adcd376c486405a535b004cf9a58a71487a11bc424acd815012 SHA256 (Python-3.11.0b5.tar.xz) = 3810bd22f7dc34a99c2a2eb4b85264a4df4f05ef59c4e0ccc2ea82ee9c491698 SHA256 (Python-3.11.0b5.tgz) = 3f7d1a4ab0e64425f4ffd92d49de192ad2ee1c62bc52e3877e9f7b254c702e60 The hashes are also attached to this email. # We hope you enjoy the new releases!
