Version 2.8 - February 2016
---------------------------
-Added digital trace averaging contributed by Michael Goertz (Thanks Michael!)
-Fixed a bug where the trigger level would invert on a CGR-201 if channel B was selected as the trigger source

Version 2.5 - July 2015
--------------------------
-Improved CGR MKII firmware update features
