Summer is almost here (at least in half of the planet) and Python 3.10 is
finishing baking in the oven. For those of you that want to taste it before
is finally ready (and if you are a library developer, you certainly do!)
you can have the second-to-last beta now, but be careful as is still very
hot ;)
https://www.python.org/downloads/release/python-3100b3/

#This is a beta preview of Python 3.10

Python 3.10 is still in development. 3.10.0b3 is the third 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 3.10 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 to have no ABI changes
after beta 4 and as few code changes as possible after 3.10.0rc1, the first
release candidate. To achieve that, it will be extremely important to get
as much exposure for 3.10 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.

The next pre-release of Python 3.10 will be 3.10.0b4, currently scheduled
for Saturday, 2021-07-10.

#And now for something completely different

There are no green stars. Why? In general, objects don’t emit a single
wavelength of light when they shine. Instead, they emit photons in a range
of wavelengths. If you were to use some sort of detector that is sensitive
to the wavelengths of light emitted by an object, and then plotted the
number of them versus wavelength, you get a lopsided plot called a
blackbody curve. For an object as hot as the Sun, that curve peaks at
blue-green, so it emits most of its photons there. But it still emits some
that are bluer, and some that are redder. When we look at the Sun, we see
all these colors blended together. Our eyes mix them up to produce one
color: white. A warmer star will put out more blue, and a cooler one
redder, but no matter what, our eyes just won’t see that as green. Due to
how we perceive color, the only way to see a star as being green is for it
to be only emitting green light. But as starts always emit radiation
following the blackbody curve, that’s pretty much impossible.

# 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.

Regards from very cloudy London,

Your friendly release team,
