WordPress 2.8.1 fixes security issues

I’ve just updated to WordPress 2.8.1, which fixes some security issues (which allowed unprevileged users to change options of some particular plugins).

The automatical update executed very cleanly. But, — as always — back up files and database before! Btw: For backing up database, I use the great wpBackup plugin.

Update:
WordPress 2.8.2 fixes the next security issue..
