I finally had some time today to do the upgrade.
My only problem so far was that the config.php got overwritten, such that ...
Code:
Content visible to registered users only.
... which of course caused a few problems when I tried to hit the main 'plog page.
I followed the upgrade instructions to the letter. Obviously just correcting the above fixed things, and it seem to be running fine. But I guess you might want to adjust the instructions accordingly.
