Welcome to the site
I think that started with the 5 series...
Version 5.2.3277 was VERY GOOD and i recommend it (Basic version)

I have 2 favourites
1) 5.2.3277 - Basic clean version
2) 5.5.3598ca - Basic NEWER clean version (CANADIAN VERSION)
In my opinion AIM GOES TO HELL AFTER 3598ca!! (Over bloated garbage)
