I just updated my WordPress from 2.1 to 2.1.1. Thanks to Mark Jaquith it was easy, by using the diff (patch) file he created. Not many things have been changed. Just some XSS-fixes and HTML code improvements…
A little update of this post. WordPress just announced that the 2.1.1 release has been breached! The code that was available contained malicious hacks! So, everyone who upgraded to 2.1.1 should immediate update to 2.1.2! I’ve just done it. However, I’m having problems with uploading every file. It looks like my FTP client is uploading the files and name them differently, really annoying!
