It would be really nice if you found a way to leave up the current build when you release the update. I imagine a number of people still playing after a year find it pretty meditative, and it's a bit sad when the specific balance and flow that you're used to disappears.
I know the windows and android versions are available for download, but as an OSX player it's a bit of a bummer. Still, you can't do all things for all people! Good luck on the new update!
