Version 2.9 has been released to the $10 and above Patrons on Patreon. Next week, 2.9.1 will be available to $5 patrons. And a few days after that, 2.9.1 will be made available on Itch for $2.00.
Please note that there are some issues in version 2.9 that the Cucumber will be patching (thus 2.9.1) before releasing to anyone other than the $10 patrons.
