Today in software quality: The Tern and Tern TX dive computers have a firmware bug that makes it use the wrong gas mix for its safety models in some - not niche - conditions (like, this is the model that prevents dive sickness by calculating nitrogen saturation in your body). That may lead to using a “less conservative model”, as they say.

Also amazing: That firmware is in the wild since January.
Also amazing: All the firmware version does on paper is enable a new paid addon for the dive computer.

This is a 600$+ device that you buy predominantly to keep you alive.
