EDIT: I’ve added the list of files that needs to be updated or overwritten.
Security-related upgrades were released earlier today for users of both the 2.2 branch and 2.0 legacy branch or WordPress. WordPress 2.2.2 and 2.0.11 addresses certain security issues and some minor bug fixes so you won’t have to worry about it messing up your WordPress theme or plugins.
If you’re an intermediate user or familiar with WordPress files and folders, you don’t have to do a full upgrade. All you need to do is identify the modified files, get the updated ones and then overwrite the existing ones on your web folder. (Assuming that you’re already running version 2.2.1).
These are the files you need to update/overwrite:
Btw, I forgot to mention earlier that I upgraded to WordPress 2.2.2 right after I posted this entry. I took less than 10 minutes. If you need help upgrading your WordPress installation, leave a comment or contact me and I’ll do my best to help you.
