This is the first development build of code slated for the 3.1 release of GC.
It includes tabbed Athletes, Compare mode and different CP model techniques.
This is a fairly major code rewrite so expect some bugs.
For Windows builds it will by default install over the existing 3.0.x software.
It will share the Athlete data from an existing 3.0.x install.
Download the development build based on commit: 2ac02e7b0b
Note: The MAC build crashes on x86_64 native machines while older machines appear fine. Use at your own risk at this time. New build is available without this issue.
