        * SYSLINUX: Resurrect the old no-mtools version of the
          installer, although as a root-only tool.  Some distributors
          have indicated that they need a small standalone installer.
+       * MEMDISK: Fix a memory offset computation error when
+         installing compressed disks which generally would cause
+         1 MB of memory to be wasted.
 
 Changes in 2.03:
        * Actually support comment lines in the configuration file.
