V6 exists now, and the HD versions are on their way up to the Google Drive, with torrents to follow. The SD versions are still encoding. I’ve updated the OP with a current changelog, with asterisks denoting V6 changes. I’m very pleased with the final product, and I’d have very few qualms about hypothetically showing it theatrically. In other words, it comes pretty darn close to passing that sort of test in my mind.
Once I’ve gotten everything out the door for TAS V6, I will have to wait on a few things from others for Episodes 3 and 4, and nearly all my source material for Episode 6. So I may jump over to Episode 8 for a while, though would hold off finishing it until after Episode 9 comes out.
