sounds like you didn't read all the stuff that's happened to him.
he has to work on new game to please Patreon people and in order to continue funding himself and his team.
DMD v.17 will come out next Wednesday but next version will be delayed...maybe not until May or so.
he is not stalling out, he is being cautious due to Patreon monitoring him. i don't blame him for keeping a tight lid on his livelihood.
I have read it all and ya he may be having issues with Patreon...There's no stopping him at all from working on game still and sending updates out through e-mail WHICH he has stated he'd do
