pretest 2022 begin

[Karl Berry]

Hi everyone.  I think the pretest area is populated with the first build
for TL 2022. See https://tug.org/texlive/pretest.html as usual for
details of how to install (unchanged from previous years), and the list
of notable changes that I've got so far. Additions or corrections to the
news are greatly appreciated.

The binaries for some of the platforms have not yet been updated (coming
soon), but the basic sets (x86_64-linux, Windows, Mac current & legacy)
are there.  Dick Koch is creating the separate MacTeX/BasicTeX packages
and they should also be available soon.

As with last year, tlnet will continue to be updated during this pretest
period. That is, regular package updates sent to CTAN will normally end
up in both tlnet and tlpretest. If a package update should only be in
the pretest, and you haven't already told me, please say so in the CTAN
upload notes.

Please don't avoid the pretest just because tlnet is being updated.
Better for everyone to test now than wait for breakage in the official
release. TL has no dedicated testers or QA department, so it's all up to
us collectively as volunteers.

Hope it flies,
Karl
