Docky now have an official development PPA, so wherever you were getting Docky from previously you’ll probably want to swap and use this one.
Of course, please note the word ‘development’ in the title; this is not a stable Docky PPA. If you’re looking for a stable Docky then I’d advise to stick to Gnome DO for now.
Of course you can still build Docky (check daily, the guys behind Docky are development fiends!) using
- brz branch lp:docky
For those that don’t know, Docky is now a standalone application and, from some point soon, no longer be part of GNOME Do.
