Thank you. I was very impressed how fast you guys moved!

Unfortunately, I'll have to wait for 28.2. But thanks for the offer
nevertheless.

I needed to move back to Emacs 27.2 because there are some other bugs
in 28.1 that I have no idea how to properly report:

- Emacs 28.1 most often crashes after loading a .emacs.desktop.

  It doesn't crash without a .emacs.desktop or with a simple one, but
  at the moment I cannot start 28.1 on any of my usual .emacs.desktop
  files without a crash. I suspect only a reboot will solve that.

  After the last reboot, I could start 28.1 once with a complex
  .emacs.desktop, for a second (simultaneous) Emacs instance with a
  different .emacs.desktop I had to use Emacs 27.2.

  Would it help to supply one of the crash dumps that macOS displayed
  and how would I submit such a bug report?

- The second bug concerns .emacs.desktop.lock files. For some reason,
  28.1 doesn't remove the lock file when exiting.

  Obviously, this isn't reproducible with `emacs -Q`. Again, how would
  I submit such a bug report?

Thanks again and have a nice weekend,

Christian

PS: ATM, I'm not set up to compile Emacs myself as I temporarily moved
    into a very small house and don't have any Linux machine here. I'm
    not masochistic enough to setup up a compilation environment on
    the little Macbook I have (which is severly lacking on disc space).
