Hi Matt;
RevMax supports current OpenX download version which is 2.8.7 and
available here
http://www.openx.com/products/source-downloadAs for starting with the svn my thought is that is a very bad idea.
If you have been around OpenX for awhile, you will know sometimes
even the public release is let out with a security issue or annoying bugs
from time to time. Most "upgrades" have been back to back to fix a bug
or issue that was just released.
If you decide to give it a try, make note of any database changes in the svn
That is where any compatibility issues might arise. I am sorry I do not have the
time to check into that myself right now.
RevMax will be updated if a new version of OpenX is released publicly that
breaks RevMax in some manor.
Mike
