 A lot of work went into the 4.1beta3 release in February 2001, and in July a non-beta 4.1 was finally released.Since that time releases (now numbered like 4.1.1, 4.1.2, and so forth) have been comparatively regular and the development pace has been relatively steady with releases occurring roughly every six months.In March 2002, Nickerson started iFAX, Inc., endeavoring to sell and commercialize HylaFAX in particular to enterprise customers.
