with v64 things got a little more drastic. the evolution of tabs and autocomplete has taken many obvious steps. despite calling all safari build's beta. you could say v60 is a beta a build, like a significant beta, while v62 v64 and v67 are more like interim builds until those features being tested are complete.
v60 was basic feature complete and v70(???) will be tab & autocomplete feature complete...
my opinion anyway... and there are probably flaws in my thinking. oh well.
