 ## Limitations / Know Issues / TODO's
 
-- Doesn't work with Arduino 1.5.x yet. Follow [issue #45](https://github.com/sudar/Arduino-Makefile/issues/45) for progress.
+- Doesn't support SAM boards yet.
 - Since it doesn't do any pre processing like Arduino IDE, you have to declare all methods before you use them ([issue #59](https://github.com/sudar/Arduino-Makefile/issues/59))
 - More than one .ino or .pde file is not supported yet ([issue #49](https://github.com/sudar/Arduino-Makefile/issues/49))
 - When you compile for the first time, it builds all libs inside Arduino directory even if it is not needed. But while linking only the relevant files are linked. ([issue #29](https://github.com/sudar/Arduino-Makefile/issues/29)). Even Arduino IDE does the same thing though.
