Update 4.2.0 dev

Documentation/changelog.md

+### Version 4.2.0
+* New configuration systems (Now you can create a separate file with all configuration and use it in you FW update)
+* New namings for file
+* Added more documentation inside configuration file
+* More checks for feature incompatibility during compilation
+* Codeclean
+* General bugfix
+* Removed legacy support for old configuration (Do not use your old configuration files, namings and position for configuration has changed)
+
 ### Version 4.1.5
 * Added dot for SD write operation
 * Added statistics menu

-//
-// M100 I Initializes the free memory block and prints vitals statistics about the area
-// M100 F Identifies how much of the free memory block remains free and unused.  It also
-//    detects and reports any corruption within the free memory block that may have
-//    happened due to errant firmware.
-// M100 D Does a hex display of the free memory block along with a flag for any errant
-//    data that does not match the expected value.
-// M100 C x Corrupts x locations within the free memory block.   This is useful to check the
-//    correctness of the M100 F and M100 D commands.
