5.666 was the last full release of 'classic' Winamp. What is currently offered is an incomplete 5.8 beta that's "not an on-going project" (which is what was stated on their website for that download for over 3 years) so take of that as you will.

From the job listings that have been seen for their new team (which also confirmed they'd done nothing for many years despite the marketing lies) imply something that is completely different with the Winamp brand slapped on it.
