All the bugfixes from the 0.7.4 release are available in 0.7.5 along with a few new features, most notably the remove server button in the "manage game" page options for easier uninstall/config removal of unwanted game installs. It's not pretty but it's only intended to be usable until the UI team takes a crack at it later, closer to the 1.0 release.
I also added quota checking (an option to disable it is in the global config editor in WHM, or edit cpgsd.cfg and set to 0). This currently will prevent a game install if the user is already at or over their disk quota with a relveant error message (whereas before it acted like it installed but didn't complete.) I plan in the future, once this is more robust, to see if there is enough avialable space for the install to complete before starting. If anyone has a problem with this feature, please put in a ticket for me so I can find out what link in the chain is breaking. Of course if you run into other problems let me know as well.
