Welcome to the AppleBlossom wiki!
Right now the AppleBlossom user manual is 25% complete. AppleBlossom itself is about 40% complete. The codebase is mostly frozen for "Fuji." At this point in time and up to and including the release of "Fuji" AppleBlossom is considered to be beta quality.
I cannot provide even a tentative release date. But here is a rough laundry list of what has been completed and what needs to be done.
