Actually, you already have it.
v0.4.1 is the latest version currently available on Itch.
The new version is still in early access for Patreon supporters.
It will become available on Itch in one month, once the game is released across all platforms where it is available.
You can wait for the Early Access period to end or pledge on Patreon to get access to it now, if you prefer.
Thanks for your support! :)
