Gnus number of unread articles change when switching from 22.2 to 23

Gnus number of unread articles change when switching from 22.2 to 23

[Klaus Zeitler]

Hello,
I'm currently switching often between 22.2 and the CVS version
(The CVS version is sometimes unbearably slow, but I haven't found enough
time to investigate this).
Every time I switch from 22.2 to 23 and use gnus in emacs 23, gnus shows
lots of unread articles in the group buffer.
Now if I read them or use catch up, then use gnus in version 22.2 and
finally use the CVS version again, the articles are shown as unread again.
Is there an incompatible change between the 2 versions?
Where should I start investigate this?

Thanks
Klaus

Hello Klaus,

Probably on emacs.gnus.general, although a lot of people on
emacs.devel use gnus and know it well.

I've got no idea what might cause this, but I see the same problem.

Have you ever considered how much text can fit in eighty columns?  Given that a
signature typically contains up to four lines of text, this space allows you to
attach a tremendous amount of valuable information to your messages.  Seize the
opportunity and don't waste your signature on bullshit that nobody cares about.

Hm, the Gnus manual states that downgrading from Oort Gnus (5.10.x) to
older versions isn't a good idea.  So I dare to say that switching
between major versions may lead to troubles in general.

Yes, see etc/GNUS-NEWS.

Read the sections about marks in the mentioned file.  You may want to
set nntp-marks-is-evil to t if you keep switching between the to
versions.  Another idea would be to use No Gnus in Emacs 22.
