Mr. Keffer brings up a point that I've been interested in as a student
(practically from the beginning) of computer science starting back in
the 1950s and 60s following what was a mathematical branch, but then
into system and compilers.
The question, sort of a diversion from the on topic discussion on WeeWx
and what runs, is the philosophy behind upgrading compilers and OSs. To
some degree it hits WeeWx developers as they upgrade but also need to
make sure that old stuff, as much as it can, will run under new releases
of compilers and interpreters.
Tom did an upgrade pass on a driver for me that isn't widely used, but I
wasn't smart enough to know what to change when Python 3 came out. The
old Python statements were not incorporated into or changed
significantly when 3 was released.
Unless there is a major change (for instance a different database
method, for crude example), why don't language developers support the
old stuff so users aren't frustrated when they attempt to stay up to
date but have legacy stuff they'd like to run. I know Windows made and
continues to make changes which are security related (we'd all be better
off if there weren't nasty people out there, but there are).
In this example I cannot see how no longer supporting "textsize" would
represent a security risk or something that would be so important that
the code maintainers wouldn't want to at least let old stuff run. Yes,
I have heard in the WeeWx discussions from the developers that changes
to solve problems or make things better are being made. And that is
opening up new capabilities, but most of the time those changes don't
seem to slam the door shut on upgrading, or having to choose to stay behind.
Just a philosophical question, but this example brings out my curiosity
as to how and why major deletions in capacity are made. Eons ago when I
worked on a system that used dBase (yes, I'm that old) one thing we did
was to make sure that the old stuff ran under the new releases, as much
as possible. It was just what we were told to do. Anyway, you guys are
so deep into this as part of your daily lives that I wonder if you have
thoughts on the decision to not support 'textsize' as it used to be.
Sorry for the diversion, but it is part of programming, I guess. Dale

This is caused by upgrading to Pillow 10, which has removed the
attribute "textsize". There have been several email threads about
this. For example,
https://groups.google.com/g/weewx-user/c/F1oLMD8_3MQ/m/Gir1m-9RAgAJ
You can either downgrade Pillow to 9.x, or cherry pick the fix as
described in the email thread, or use the beta of WeeWX V5.
