Update to the master code that is slated for Version 3.1.
The Developers have asked if people could look to see if they can recreate the issue CRASH: Create Interval… #775 with these builds. This is most likely going to affect Mac users.
The Mac (10.7+ QT5.2) build does not have 3D plotting capabilities and unless you have installed the D2XX drivers on you machine you will not have D2XX download capabilities either.
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: 79e5e8df18
