No functional change.
VPINs are unsigned integers in the range 0-65535 (although the highest values are special, 65535=VPIN_NONE). Values above 32767 were erroneously being displayed as negative. This has been fixed, which is a pre-requisite for allowing VPINs above 32767 to be used.
Two new drivers: PCA9685pwm drives the PCA9685 I2C device directly, and Servo driver which acts as a 'shim' over the top to control animations. This is aimed at supporting devices like the EXIOExpander by allowing the Servo driver to talk to the EXIOExpander driver instead, to animate servos on another controller.
