A problem where the rich text editor wasn’t being loaded due to compression issues has been worked around.
Extra security has been put in place to better protect you from plugins that do not do explicit permission checks.

The steps I took to update my wordpress 2.8 site to 2.8.1 was:
Backup my database, and all my wordpress files on my wordpress root folder.
Disable all plugins for Word press
Download the latest version of word press, and extract the zip folder.
Upload all the new files to my wordpress root directory and let all the old files be overwritten.
and I ran wordpressaddress/wp-admin/upgrade.php
re-login to my site and enable all my plugins.
Check all the pages on my site to see if they are functioning.
Now I am using 2.8.1 for wordpress.
