*This is the first release candidate of Python 3.10*
This release, **3.10.0rc1**, is the penultimate release preview. 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 2021-09-06 while the official release is planned for 2021-10-04.

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.

*Call to action*
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*

In theoretical physics, quantum chromodynamics (QCD) is the theory of the strong interaction between quarks and gluons, the fundamental particles
that make up composite hadrons such as the proton, neutron, and pion. The
QCD analog of electric charge is a property called color. Gluons are the
force carrier of the theory, just as photons are for the electromagnetic
force in quantum electrodynamics. There are three kinds of charge in QCD
(as opposed to one in quantum electrodynamics or QED) that are usually
referred to as "color charge" by loose analogy to the three kinds of color (red, green and blue) perceived by humans. Other than this nomenclature,
the quantum parameter "color" is completely unrelated to the everyday,
familiar phenomenon of color.


*We hope you enjoy those new releases!*
Thanks to all of the many volunteers who help make Python Development and
these releases possible! Please consider supporting our efforts by
volunteering yourself or through organization contributions to the Python Software Foundation.
