CLANNAD is now playable to the True End of the After Story. All routes in Kanon SE are playable, and there’s a minimal default interface for Kanon and other games that don’t provide a custom one.
rlvm still does not handle rlBabel translation patches very well. This is the major planned feature for 0.5, now that there appears to be an incoming Kanon translation patch, along with the ongoing CLANNAD translation work.

I thought I should also mention that the whole project history, in addition to being hosted locally, is now also on github, for those interested in following development or contributing.
