Hi all, 

the 23.0 profiles are ready for testing, including stage downloads,
binary packages, and update instructions for existing installations,
for all arches.

IMPORTANT Exception IMPORTANT
** musl on (32bit) arm and x86 does NOT work yet (gcc build failure) **

IMPORTANT Update instructions IMPORTANT
https://wiki.gentoo.org/wiki/Project:Toolchain/23.0_update_instructions

Stage downloads (temporarily, for all arches):
[preferably] https://distfiles.gentoo.org/experimental/x86/23.0_stages/
[direct/osu] https://gentoo.osuosl.org/experimental/x86/23.0_stages/

The changes can be seen here
https://wiki.gentoo.org/wiki/Project:Toolchain/23.0_profile_transition

and the timeline so far here
https://wiki.gentoo.org/wiki/Project:Toolchain/23.0_profile_timeline

The update instructions also double as the news item that should be
published max. 1-2 weeks from now. They are mostly unchanged compared to 
my last e-mail, just some wording has been clarified.

Note 1: The next steps are, now really in 1-2 weeks max:
* make 23.0 profiles the same stability level as 17.x profiles,
* degrade 17.x profiles all to exp (so the CI doesn't explode)
* publish news item
* replace stage downloads with 23.0 version (in situ)

Note 2: While there are 23.0 split-usr profiles, the *stage* downloads
are *all* of the merged-usr type. Why? Not because I'm a big fan of that, 
but because we should try to unify and standardize a bit again - to 
avoid too many different build configurations leading to too many Heisenbugs.

Note 3: amd64 now has CET turned on by default.
https://docs.kernel.org/next/x86/shstk.html
If you have already used the unannounced 23.0 profiles, you should wipe
your package cache and emerge -ev world now.

Note 4: arm64 does *not* have its equivalent turned on yet since we
encountered last-minute problems (guess what, gcc build failure).

Note 5: There are no hppa builds yet since our machine is still busy.
One gcc build takes about a week there.

Cheers & have fun,
Andreas
