* Build products are now created in a separate build directory tree.
+* Analyze at link-time whether bootloader images will fit in memory and won't
+ overlap each other at run time. If it is not the case then image linking
+ will now fail.
+
+* Reduce the size of the bootloader images by cutting some sections out of
+ their disk images and allocating them at load time, whenever possible.
+
+* Properly initialise the C runtime environment. C code can now safely assume
+ that global variables are initialised to 0 and that initialised data holds
+ the correct value.
+
+* General changes on the memory layout: some sections have been moved, some of
+ them have been merged together, and some alignment constraints on sections
+ have changed.
