                       ## Volt Ampera fixes (from Michael)
                       ## Support net_fnbits NET_FN_12VMONITOR and NET_FN_SOCMONITOR to
                          allow vehicle module to control what is monitored

2013-04-01 2.2.5       Firmware 2.2.5
                       ### Fixes for charge notification logic on VA
                       ### Show charge, trunk and alarm notifications in DIAG mode
                       ### Speed, parking, and general tidy-ups for VA
                       ### Switch ambient temperature to PID 0x801f for VA
                       ### Auto-calibration for 12V line reading
                       ### Twizy version 2.6.1 - power line plug-in detection
                       ### Add car_doors5 for rear doors, frunk and 12v charging
                       ### 12v alert by MSG protocol fix
                       ### Rework of 12V reference logic
                           - Filters out single peaks / misreadings
                           - Sends "OK" alerts if voltage level restores w/o charging
                           - 15 minutes calmdown before taking new ref voltage
                           - No alerts while car is on
                       ### ESS SOC DIAG (for TR)
                       ### Initial support for CAC in TR and TZ modules
                       ### Experimental Tazzari (TZ) module
                       ### Experimental Nissan Leaf (NL) module

Major changes are the experimental support for Tazzari Zero, some bug fixes and 12V work on Twizzy, and support for CAC readings in Tazzari and Tesla Roadster. The CAC is a useful indicator of the health of the vehicle's battery, and is being asked for in the Tesla Long Term Battery study. Pending App support, you can get CAC from an SMS "STAT" command.
