So you’ve most likely seen all different versions of the same software (Microsoft Word 93, XP, 2007, etc). Many technology companies will make upgrades to pre-existing versions of software products. These companies then make massive releases and announcements informing users of the new biggest thing. Occasionally companies will have good intentions with new versions of software. Sometimes there’s an apparent need for new software versions to be released since the old one just plain didn’t work (Windows Vista…case in point).
