Let's record my 3.23 to 3.24 upgrade attempt.
I untar Mail-SpamAssassin-3.2.4 and of course read the file entitled
UPGRADE.
In it I find "Note for Users Upgrading to SpamAssassin 3.2.0".
But I am upgrading to 3.24.
Go ahead and call me dumb, but if I mess up, I might endanger my
email.
Now I look in README. No, no instructions there.
OK, now looking at INSTALL
Upgrading SpamAssassin?
-----------------------
Please be sure to read the UPGRADE file for important changes that
have been made since previous versions.
Installing or Upgrading SpamAssassin
------------------------------------
OK, looks like I am on the right track. (I recall upgrading MediaWiki
was more intuitive.)
OK, now after reading the whole INSTALL file, I come to the conclusion
that to upgrade, one just acts like one never installed SpamAssassin
in the first place, and apparently the new SpamAssassin will just
install on top of the old one (with cruft surely accumulating in the
corners, I bet.)
OK... it all worked out. I even remembered to do sa-update, a step
mentioned in here in the newsgroup, not in the highly cluttered
INSTALL file.
OK, see you back here when 3.25 comes around, as I don't remember anything.
