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:
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!
