No exact date yet, but for any WIP update, only those who qualify for beta access will be able to try it out, and for the rest- it will probably be the full release.
Right now, I do have a new chapter or two that hasn't been released even to beta access, but it's not yet ready (incomplete assets, placeholders, incomplete branches, etc.).
I always announce major updates though, but I haven't had any for a long time due to personal family circumstances >_<
