Update to latest Marlin ?

[mediaklan]

Hi everyone !
Let's say I want to update the firmware I have for my Prusa i3 Pro B to the latest Marlin-RCBugFix : which files and sections from the Marlin-RCBugFix do I need to modify accordingly ?
Do I only need to modify the configuration.h file or are there others I need to pay attention to ?
Thanks in advance for your advice !

Answer to myself : Got it to work modifying only configuration.h (and removing the #include files at the end of the conf), but it do not seem that great. More tests needed, maybe with keeping the #include line and the files from my previous firmware.
