We're planning to release v0.15 later this month.
If you want to try it early, you can switch to the experimental branch on Steam today. The update is already available there. It's still getting daily updates (mostly balancing), but it is very stable.
If you're in the middle of a run and don't want to switch yet, that's fine too. Even after v0.15 is released, you'll still be able to finish your current run on v0.14 by selecting the v0_14_x branch under Properties → Game Versions and Betas in Steam.
Thank you for your patience!
