Does anyone want bug fixes? Because we have 164 new commits fixing different things, from code to documentation. If you have reported some issue after 3.11.0b1, you should check if is fixed and if not, make sure you tell us so we can take a look   We still have two more betas to go so help us to make sure we don’t miss anything so everything is ready for the final release https://www.python.org/downloads/release/python-3110b2/This is a beta preview of Python 3.11Python 3.11 is still in development. 3.11.0b2 is the second 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 3.11 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 (Monday, 2021-08-02). Our goal is have no ABI changes after beta 4 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 3.10Among the new major new features and changes so far:PEP 657 – Include Fine-Grained Error Locations in TracebacksPEP 654 – Exception Groups and except*PEP 673 – Self TypePEP 646 – Variadic GenericsPEP 680 – tomllib: Support for Parsing TOML in the Standard LibraryPEP 675 – Arbitrary Literal String TypePEP 655 – Marking individual TypedDict items as required or potentially-missingbpo-46752 – Introduce task groups to asyncioPEP 681 – Data Class Transformsbpo-433030– Atomic grouping ((? >…)) and possessive quantifiers (*+, ++, ?+, {m,n}+) are now supported in regular expressions.The Faster Cpython Project 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.

No current physical theory can describe timescales shorter than the Planck time, such as the earliest events after the Big Bang, and it is conjectured that the structure of time breaks down on intervals comparable to the Planck time. While there is currently no known way to measure time intervals on the scale of the Planck time, researchers in 2020 found that the accuracy of an atomic clock is constrained by quantum effects on the order of the Planck time, and for the most precise atomic clocks thus far they calculated that such effects have been ruled out to around 10^−33s, or 10 orders of magnitude above the Planck scale.We hope you enjoy the new releases!Thanks to all of the many volunteers who help make Python Development and these releases possible!

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/This is a beta preview of Python 3.11Python 3.11 is still in development. 3.11.0b5 is the last of five planned beta release previews.

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).We hope you enjoy the new releases!Thanks to all of the many volunteers who help make Python Development and these releases possible!

At this temperature, the wavelength of light emitted by thermal radiation reaches the Planck length. There are no known physical models able to describe temperatures greater than the Planck temperature and a quantum theory of gravity would be required to model the extreme energies attained. Hypothetically, a system in thermal equilibrium at the Planck temperature might contain Planck-scale black holes, constantly being formed from thermal radiation and decaying via Hawking evaporation; adding energy to such a system might decrease its temperature by creating larger black holes, whose Hawking temperature is lower.Rumours say the Planck temperature can be reached in some of the hottest parts of Spain in summer.We hope you enjoy the new releases!Thanks to all of the many volunteers who help make Python Development and these releases possible!
