[RELEASE] Python 3.10.0rc2 is available
Python 3.10 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-3100rc2/

This is the second release candidate of Python 3.10

This release, **3.10.0rc2** , is the last preview before the final release
of Python 3.10.0 on 2021-10-04. Entering the release candidate phase, only
reviewed code changes which are clear bug fixes are allowed between release
candidates and the final release. There will be no ABI changes from this
point forward in the 3.10 series and the goal is that there will be as few
code changes as possible.

*The next release will be the final release of Python 3.10.0, which is
currently scheduled for Monday, 2021-10-04.*

Call to action
??????????????
*The 3.10 branch is now accepting changes for 3.10.**1*. To maximize
stability, the final release will be cut from the v3.10.0rc2 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 3.10.0, look at the short-lived branch-v3.10.0
https://github.com/python/cpython/tree/branch-v3.10.0 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 3.10 compatibilities during this phase. As always,
report any issues to [the Python bug tracker ](https://bugs.python.org/).

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

And now for something completely different
Maxwell's demon is a thought experiment that would hypothetically violate
the second law of thermodynamics. It was proposed by the physicist James
Clerk Maxwell in 1867. In the thought experiment, a demon controls a small
massless door between two chambers of gas. As individual gas molecules (or
atoms) approach the door, the demon quickly opens and closes the door to
allow only fast-moving molecules to pass through in one direction, and only
slow-moving molecules to pass through in the other. Because the kinetic
temperature of a gas depends on the velocities of its constituent
molecules, the demon's actions cause one chamber to warm up and the other
to cool down. This would decrease the total entropy of the two gases,
without applying any work, thereby violating the second law of
thermodynamics.

We hope you enjoy those new releases!
