Johan has just announced that based on feedback he has made some updates and created a revision 3.1 board. He reports the changes are small, mostly related to the size of the mounting holes for the components to ease assembly.
In regards to purchasing one of these boards, sales are currently paused due to COVID-19, however when the epidemic is over he plans to start selling the boards on Tindie for $40. He notes that he will also release the gerver files necessary to make these boards later this year under an open hardware license.
