I've been doing some support in the forums lately and could collect some Feedback on current upgrade Issues. Therefore I created a PDF that should Guide new Users better for their next upgrade:

Feedback welcome.
You mean that one? http://codex.wordpress.org/Backing_Up_Your_WordPress_Files
Maybe you get a cached version of that page, for me it is working.
Updated the File and added another one. Started a new thread: http://wordpress.org/support/topic/167394?replies=1
But I can not close this one. why?
