I added file revisioning support to .htaccess files, so that every time you update or change the .htaccess files it saves the old copy. The next release will provide a DIFF view of the differences. Version 4.7 Almost Done
You can view the plugins home page, or view it on the wordpress.org site.
Also fixed all the bugs I was notified about or found, and provided the option to bypass some of the testing if you know your server supports something.
I have to get back to my real job now :) but for the next release I'm going to add a whole user-management area to add and remove users and groups from .htpasswd files.
Then it will be ready to start using the advanced SID's like mod_security..
