bartender or dominos

Is there a place we can get specific addons for this specific patch? I mean I can go to curse and go to the changelogs for it, but if there's a faster way, I'm interested.

I am afraid not.

Curse does not always keep desired versions (many wotlk are deleted already). Wowace keeps all of them.
