[Python-announce] [RELEASE] Python 3.11 release candidate 2 (3.11.0rc2) is available
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:pablog...@python.org

The next release will be the final release of Python 3.11.0, which is
currently scheduled for Monday, 2022-10-24.

# 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
