The complete, extended version of FL W3 will be released on Steam in Q2 of 2023 (so anywhere between April 1st and June 30th); I expect it to be towards the end of that date range
As to whether there will be further releases between then an now, nothing has been said. I lean towards no since the Ext version is already up to Day 20
Maybe I'm just in a strange mood but
thank you for sincerely answering this question, I was about to ask if myself if it wasn't answered in the last week since I wasn't going to scan all 350+ pages of this thread.
I half expected someone to respond, unhelpfully, that I should just use search. I tried that unsuccessfully.
(Unrelated rant/undirected suggestion: I have a soft spot for the classic forum system but frankly I think these games, especially popular ones with thousands of posts, should be sub-forums with their own sub-topics to make questions re: release dates, walkthrough, mods, saves, bugs, etc easier to find.)
