0.42 will no be available to the public. The public version is updated every 6 month months.
This does not mean in 6 months you'll get 0.42, but rather 0.44 when 0.45 is released to the Patrons.
We work on a 2-month development cycle for updates (Used to be a new update every month, but crunch was getting a bit too much for our team.) so every 2 months there is a new update to Uni with every 6 months updating the public build.
Eventually, once all of "Act 1" is finished i.e all conflict events, and all route lock and side events are cleaned up, the public updates will stop altogether as that will be a stable enough build with enough content for a good public demo.
