v6.1 [Sep 11, 2018]
Improvements to log file & added /alarm command line option.
v6.0 [Jan 19, 2018]
Optimized for computers with >4GB ram. Particularly significant for Deluxe users. If you are testing 8GB or more you need this version. If testing less than 4GB, 5.x may actually be slightly faster. Based on extensive empirical research we have updated the percent coverage metric; testing to 100% will catch all errors except for intermittent failures; to detect intermittent problems test to 400%.
v4.1 [Jul 30, 2014]
New in version 4.1: Improved Windows 7/8 support.
v4.0 [Nov 19, 2009]
