I've released firmware v2.2.2 to the github repository. The change log is as follows:

                           Volt/Ampera work-in-progress

                           First draft of OVMS Development document
                           Twizy user guide v1.0.1

The .hex files have been built for all configurations. I (and others) have tested this in hardware v2 vehicles, but so far this is pretty much untested with v1 hardware (in particular for Tesla Roadster). I would appreciate it if you guys could test it and make sure it is ok for v1 hardware in Roadsters.

Once you upgrade firmware to v2, you will need to either (a) SMS "MODULE" command again to include the fourth parameter vehicle type "TR", or (b) use the iOS App to set feature #14 to "TR". You will require this for the CAN bus stuff to work. I have updated the Tesla Roadster user guide to reflect this new parameter.
