             - Added A20 line Enabling to MBR
 2018/12/21  - Boot is now in two stages. First stage is 512B MBR code that loads second stage loader from FAT16.
               That second stage loader enables A20, switches into long mode and write colored text =D
+[...]
+2019/03/17  Well... After the Time Skip, we now have many many changes.
+            - Migration to GRUB now complete
+            - The Kernel boots, prepared by the loader. Both are loaded by GRUB
+            - We chose to use Multiboot v1 because the v2 lacks on documentation
+            - We only support x86_64
