The manual isn't finished, but it's in good enough shape to be pushed to dev so we can all look it over.
All I've changed in the libraries is to hide some helper blocks, but not as many as I'd like. :)
I intend to keep working on the colors library speedup, so there's no urgency for you to pull this I guess, but this is a stable state of both libraries and you /can/ pull it when you're doing a release (or a dev version) anyway.
The library could still probably be improved, but it uses the new primitives so it's way faster already.
I think I'm finished working on 6.6, release when ready.
