If you are a supporter, you get version 4.23 right now (minimum paid value of 1 USD). Otherwise, it becomes free on the last day of February. You can read a bit more about it on the blog. The changelog is below.

Minor
*Overhauled music loading so only music relevant to the active chapter should be loaded. Should save a small amount of memory.
*Stamina bar now renders independently of the rest of the world UI (if enabled).
*There is now an option to adjust how often voice clips play in the audio options menu.
*Added badges to chapter 1. These are gained when you get a new monster form (including transforming into one you already have on an older save!) and make that type of enemy not target you.
*A modified skills icon appears to let you know you have gained over 500 JP without checking the UI lately.
*You can now use the rubber queen costume as rubber Mei during the rubber sequence (thanks, Klaysee!)
*Added cloud save support to Steam version. Let me know if it doesn't work!

Combat Balance
*Slightly adjusted the "Balance" of the rubber sequence. You now have a special move that can spread rubber to all enemies.

Bugs
*Fixed the sign near the trading post causing the player to crouch.
*NC+ should no longer immediately trigger the mannequin subquest without speaking to Victoria first if the items were carried over.
*Fixed typos.
*Fixed tutorial saying your stamina bar is in the top left (it can also be a ring now!)
*Fixed audio clips playing and delaying combat even when the abstract volume for that character is 0.
*Fixed two bestiary entries that said they could TF you but boy they could NOT (thanks, emailer!)
