PINMUX_PINMUXPINSFILE name changed on current beaglebone black release

[3D-Lasers-Lab]

I was able to change the following two lines in the source code and then I was able to get past the error messages I was getting. (I am now getting "Access to the path '/sys/class/gpio/export' is denied." but that is most likely an issue on my end and not an issue with the library.

// the file which contains the pinmux pins in use
public const string PINUMUX_PINUMUXPINSFILE = "/sys/kernel/debug/pinctrl/44e10800.pinmux-pinctrl-single/pinmux-pins";
// the file which contains the pins information
public const string PINUMUX_PINSFILE = "/sys/kernel/debug/pinctrl/44e10800.pinmux-pinctrl-single/pins";
