Yes HL, I have actually. The only modification to the database is 2 additional INSERTS into the 'sys_options' table that allows the admin to set the security impact levels. This would allow the admin to do something such as add a simple HTML block with valid HTML code and not get a Possible Attack error page or 1,000 emails per minute, as well as other things.

The rest are just updated php files. Since AlexT provided the fix, I would hope that he also took it into consideration. I just decided see more to package it all into 1 download instead of going through 6-7 change sets and editing the same php file 3 or 4 times. I would not think that these 2 inserts would restrict the upgrade from RC1 to RC2, however I could be wrong.
