My apologies for any confusion you may have experienced.
itchio's free public build is scheduled to get the new art update post starting in March. Version 9.9 is due to launch this month.
Patreon just rolled out version 10.2 which was posted on the 28th. You can find it on the Posts page, third article on the page, or just click on the "Sins and Paradise" tab at the top of the screen to immediately find it.
NOTE: You have to be a $3 a month level patron in order to have access to the most up-to-date version of the game.
Thanks for the question. I'm sure it will help others who experience the same issues.
