Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Prepare custom block update function: In the flash area of the font lib some sectors may be used for custom data or a boot updater image. With this change a flash option is added to the maintainance menu. IMPORTANT: The fimwareEraseProgram.c is needed for compiling the firmware now => Add it e.g. by adding a link from the OtherSources location to your source folder.
