Could some one please explain what are "Chromatic", "Chromium", "Google Chrome", "Chrome Canary", etc., and, in particular what the numbers mean, i.e. 13.06.788.69 as a version number. I assume that a number beginning with 13 is a later version than one beginning with 12, but where do the rest come in? Furthermore, is there any correspondence between any two of these e.g. Chromium and Canary, and finally, which of these are final versions, which are betas, and which are developer's models?
