Marlin 2.1.3-b2 missing endstops

Hello everybody,
I am trying to build my own handmade 3D printer, based on Marlin and Arduino Mega 2560. I have been working on the latest stable version of Marlin, ie 2.1.2.5 (at the date of writing), but in order to enable also the M210 command ( which appears to be working only since 2.1.3 on) I have switched to the beta release 2.1.3-b2.
The issue I raise here is that all the "MAX" endstops, which are well present in my hardware, seem to be missing when I run the M119 command.
It must be remarked that in the configuration.h all the statements such as
#define USE_XMIN_PLUG
#define USE_YMIN_PLUG
#define USE_ZMIN_PLUG
...
#define USE_XMAX_PLUG
#define USE_YMAX_PLUG
#define USE_ZMAX_PLUG
are no longer needed and therefore canceled. But where to inform 2.1.3-b2 of the existance of such switches?
Thank you for helping
