Firmware 3.1.0 Query

Hi,

I've downloaded the latest firmware of github. I would like to edit the firmware to add additional bed leveling points as i did with my previous firmware version. On trying to verify the code prior to compiling i am getting an error as below.

Arduino: 1.6.8 (Windows 10), Board: "RAMBo"

WARNING: Category '' in library Wire is not valid. Setting to 'Uncategorized'
Warning: platform.txt from core 'Marlin AVR Boards' contains deprecated recipe.ar.pattern="{compiler.path}{compiler.ar.cmd}" {compiler.ar.flags} {compiler.ar.extra_flags} "{build.path}/{archive_file}" "{object_file}", automatically converted to recipe.ar.pattern="{compiler.path}{compiler.ar.cmd}" {compiler.ar.flags} {compiler.ar.extra_flags} "{archive_file_path}" "{object_file}". Consider upgrading this core.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

It would seem it's looking for multiple extruders but i don't have the MM upgrade. I used the variant file 1_75mm_MK2-RAMBo13a-E3Dv6full.h so not sure why it would be doing this. Can anyone point in the right direction?

Thanks
