It's more coincidence the Miles it too busy to sync.

Did anyone verify that Stefan's changes are safe also for Emacs 21/22
and XEmacs 21.4/21.5?

As No Gnus 0.8 is just a development snapshot, I don't want to invest
too much time to enforce such a policy.  (And I didn't know when the
release will be done, because I didn't hear from Lars for some weeks.
Maybe he was on holidays.)

As pointed out in <news:v98wzmon51.fsf@marauder.physik.uni-ulm.de> /
<http://thread.gmane.org/gmane.emacs.gnus.general/66553/focus=66746>,
it's not very important to have the Gnus 5.10.10/No Gnus 0.8 work with
Emacs trunk:

- It's important that Gnus 5.10.10 works well with Emacs 21 and XEmacs
  21.4/21.5.  Users of Emacs 22 should use Gnus 5.11 bundled with
  Emacs 22.2.  Users of Emacs 23 (trunk), shouldn't use Gnus 5.10 at
  all.

- It's important that No Gnus 0.8 works well with Emacs 21/22 and
  XEmacs 21.4/21.5.  Users of Emacs 23 (trunk), should use either the
  bundled Gnus 5.13 or Gnus trunk (when Gnus trunk is newer).

Or at least cc ding@gnus.org when doing non-trivial changes in
lisp/gnus/*.el or changes that are likely to be relevant for Gnus.

Maybe it would have been better to send
<http://thread.gmane.org/v9y786slel.fsf@marauder.physik.uni-ulm.de> to
emacs-devel as well.

Bye, Reiner.
