RARLAB has officially released the final version of WinRAR 5.0. See what's new here I find there is not so many drastic changes on GUI, as the matter of fact there is no changes at all from the first time I knew WinRAR (v3). Surely they still preserve their philosophy on functionality than being an eye candy. Just like before, old license keys from previous versions do not work. I already tried my v4 key. Let's see if I can ask for an upgrade.
