I am a bit wary of installing a new firmware on my CB2 right now, as it seems to be working quite well, and CU has a history of breaking something when a new version is released. And also, my machine has lost count of operating hours twice during firmware updating, and while not critical, it is annoying.

However, I'm still curious about some of these changes, perhaps mostly what the T-params are. Would be nice if these could be documented somewhere.

Janos, you also mentioned that getting usable wifi speeds for the CB2 was coming, but I see no mention of that here. When will that become available?

I guess those T params mean, that the new firmware will not barf on seeing the head (tool) selection codes if the slicer includes it for one head printer. Either ignores T0 or ignores T altogether.

Examples from the head wrench gcode:
M104 S250 T0
M109 S250 T0
