I don't really know what to say, they've been updating and supporting Transmit forever.
(To be clear: I am personally entirely fine with the idea that software needs to be paid for, and wish they could charge for upgrades in a reasonable fashion so as to have a real business model; but the emphasis on form over function, with tons of marketing and descriptions about how pretty the software is when core functionality like terminal emulation never worked correctly, is really irksome.)
(After writing this, I realize you are probably joking, in that Prompt 2.0 will soon exist and thereby the bullet points will be complete, but on the oft chance that you were serious I have left the previous paragraph ;P.)
Do you have more I can read about this? That is really interesting!
