There's one single problem about that: apparently, the mysql connection is still stored in the db itself, which doesn't seem to be the case w/ newer versions. The effect of this is that I had to change the mysql password in the meantime, so every time I update s9y, it "remembers" the old password from the db, giving me error messages until I change it manually in serendipity_config_local.inc.php. This is kind of a hassle since I have to reset this file's permissions first, using a rather cumbersome interface by my web hoster, only to set them back to the PHP user after uploading the manually edited file.
So I was wondering if
a) there's anything I can do about this and
b) is there any other potential "baggage" from earlier versions I could or should get rid of?
