//S3 mode setting on power up is now loaded correctly. Wasn't getting set until a second ReadNVM or manually set.
//Changed Position accel/deccel handler to take into account existing motion when a new command is executed.
//Added responsiveness slider to Autotuner. After autotuning the slider can be used to easily adjust the tuned settings for responsiveness(until IonMotion is restarted or the Autotune mode is changed(eg from PD to PID to PIV).
//Removed PID setting commands from python examples. We recommend you etup the Roboclaw and save the settings to the board before usign the examples. Having default values make customers assume those values would work well with any motors.

//Added S3,S4 and S5 signal pin options.
//Added voltage clamp output control options to signal pints. Used to drive an active external voltage clamp circuit to dissipate regen energy when usinga power supply
//Added simple Homing support(using S4 and S5). When enable, using an active low switch to detect the home signal, the unit will automatically move forward out of the sensor on power up if the home signal is already triggered, and then move backwards until the home sensor triggers. When moving backwards into the sensor there is a 5 second timeout. Power used is limited to 25% PWM.
//Added non-latching E-STOP(doesnt require a reset to clear)
//Added Sign magnitude PWM mode. All V3,V4 and V5 boards except Roboclaw 2x60A V4 boards support new mode. Roboclaw 2x60A V5 boards will support this mode when released.
//Added a command to read back current motor PWM settings(to detect when PWM is saturated when under PID control)
//Added user max current settings. Allows user to set lower maximum current limits
//Changed how Roboclaw handles over voltages. Units will now use active braking when regen over voltage is detected above the user set maximum main battery voltage until the over voltage has dissipated. An over voltage of this type is caused when a motor is slowed down too fast when attached to a power source that can't handle the regen. This will prevent large over voltage spikes under these conditions which could damage the unit and/or power supply.
//Changed how Position commands function when using PD and PID tuning. Acceleration/decceleration curves now function with them just like when using the PIV tuning.
//Updated Autotuning algorithms for all modes. Position autotuning now requires the QPPS value be set by the user before tuning instead of the system trying to autodetect the motors QPPS. Velocity tuning still autodetects the QPPS value.
//Added magic numbers to WriteNVM and EnterBootloader packetserial commands. Prevents accidtenal writes by the user.
//Adjusted overcurrent temperature range calculation
//added button swap option to general settings
