[Ovmsdev] v2.2.6

Thanks. I've updated the release notes to v2.2.6 to match what you have.

So far v2.2.6 seems good for me. CAC is working, and no more 12v alerts on the Tesla Roadster.

By the way, I'm working hard towards a stable v2.2.x. The factory is doing a new production run, and needs an up-to-date firmware to flash before shipping to Fasttech (and end-users). What we have looks good, but I just want to (a) stabilise Twizy support so that it is production-ok with existing functionality (seems ok now), (b) stabilise Volt/Ampera so that it is production-ok for monitoring functionality, and (c) get the VDS error messages reporting back from the Tesla Roadster (as well as a framework for this in other cars).

Tom's charge-time predictor code will have to wait until this v2.2.x is stable, as that will need quite a bit of testing. I'll put the code in as soon as v2.2.x is out. Now that we have CAC, it should be relatively simple.

Regards, Mark.
