The largest of these is that this comes packaged with the 'lite' version of the 1.3 patch, revision 117.
There are also a number of additions to the Pack with the 2.2 patch. There have also been several (mostly redundant) modes cut from the Pack in an effort to improve both online and offline stability, as well as make it easier for anyone with the Pack to have more mods installed at once. Course, the 2.2 patch provides a number of bugfixes from the small (first-person views) to the larger (CTDs on certain maps).
