Hi,
Regarding the python version selection, here is the detailed answer I
just got from Nick Cannon on the VFX discussion list [1]:
From this year we are more strictly applying the policy that a version
must be released by September 1st to be included in the Platform for
the following year. The reason for this is to allow software providers
to have time for testing and quality assurance with the final Platform
before the window for publishing major releases against it.
We will still consider later change requests which we will share first
with the Working Group, and then here on vfx-platform-discuss for
feedback. Only if there are no objections raised will we adopt a late
change into a Platform.
So an October release of Python is too late for our regular schedule,
but it can be requested for a late change at which point we would
solicit the community for feedback.
At least now we know. No idea how likely a late change request would be
to be accepted though.

I'm not too keen on tying ourselves to the VFX platform again (for
Python versions at least).
The VFX platform has a track record of not upgrading Python for
reasons that don't make sense for Blender (availability of Python-QT
bindings & some companies simply not wanting to upgrade).
Now Blender has a track record of not following the VFX platform when
it doesn't suit us, undermining our commitment to such a decision.
This can't be reassuring to the kinds of stakeholders who might find
some benefit in Blender using the VFX platform.
Blender used the VFX platform for long enough I think we would know if
it was giving us much/anything in the way of tangible benefits.

Hi,
The only info regarding versions availability we have is that sentence:
A change in policy to only allow released versions to be included in
each year's VFX Reference Platform
This is fairly vague and unclear, since it does not specify any limit
date...
I asked about why they still stick to a fairly old python version on the
discussion thread Brecht linked (message is pending approval currently),
we'll see if we get an answer.
I would indeed much rather use a version of python that is actively
maintained during the whole year the VFX recommendations apply. And
python has a history track now of being reliable on their release dates,
so I do think VFX could be a bit less conservative on this tool (and go
back to an older version in October/November in the very unlikely case
that python would be unable to release 3.10 on time).
That being said, sticking to 3.9 for 2022 is not as bad as what they did
for 2021, so I would not be too annoyed if that was the case either.
Cheers,
Bastien

imho 3.9 is the only version they could have picked, the
proposed release date for 3.10 is 2021-10-04 [1]. While
the VFX platform aims to finalize in august [2]. I was
rather vocal last year for them putting versions on that
had not been released yet (some of which got delayed well
into 2021) I'm happy to see for 2022 a more conservative
stance has been taken.
With bugfix support for 3.9 ending on 2022-05-02 [3] that
does put them in an odd situation, they'll either have
to recommend a version that may not be released on time,
or recommend a version that will not see bug fixes for most
of the year. There seemingly is no winning solution here
since the problem appears to be the somewhat short
support window for python releases.
As much as I picked on them last year for making very
strange recommendations, I feel they struck a good balance
for 2022.

Good call.
Python was upgraded to 3.9, which will still trail behind 3.10 that will be
released this year. So the question about diverging or not will remain.
My preference would be to, for non-LTS releases at least, stick to versions
of Python that still receive bugfixes. In the past we've had crashes of
Blender that were due to a bug in Python. The only way to solve that was to
upgrade Python itself. This in itself is rare, but I don't remember having
such issues at all until we stuck to the old py3.7 to adhere to the VFX
Platform.
Is there anything known about the policy of the VFX Platform when it comes
to picking which Python version to stick to? Is it always going to be
"whatever version was released a year earlier"? Or is there still an
acceleration happening after sticking to py2.7 so long, and will they
eventually be targeting the latest versions? If it's the latter I'd be fine
with following the VFX Platform and sticking to py3.9 for a while longer.
If sticking to the platform means that for a significant amount of time
we'll be on versions of Python that don't receive bugfixes any more, I'm
less positive.
