Most importantly this release fixes shoot through (all IGBTs on) on the second startup when in active low mode.
Other changes:
The last change means that I removed 1.1 and 2.2kHz, I hope nobody used it.

This is the first official release that contains both Sine and FOC implementation. If you use an asynchronous motor, download stm32_sine.. If you use a synchronous/PMSM motor download stm32_foc.
Also in this release I fixed charge mode which I broke in the v4.55.R release

I highly recommend updating to this release when using synchronous motors.
There is also a small bugfix for single channel encoder mode

Corrected calculation of rotor frequency in speed estimator
Corrected calculation of rotor speed in resolver mode
Improved sampling SNR in resolver mode
angle displayed in ° (0-360) instead of digits (0-65536)
Corrected regen calculation for synchronous motors

Added AC current limiter in software
Using tracking loop to calculate motor velocity in Resolver and quadrature modes
Added parameter encki for finetuning speed estimation
Added parameter respolepairs for resolvers with different pole count to motor
Fixed resolver mode ADC setup
Counting number of rotor turns since startup
Added (temporary) parameters for speed estimator
Added power limits: maximum DC current in and out, throttle limiter
Added button mode for direction selection
Added error message on inverter over temperature
Added CPU load display
Saving CAN map using uids instead of parameter index -> CAN map survives firmware upgrade
Using both CAN receive FIFOs
