+20030516:
+       Due to bugs in the export handling code, invalid export lines
+       were accepted before and caused the kernel to panic when
+       mountd got restarted because it freed memory that had already
+       been freed. This has been fixed and the kernel checks
+       export addresses very strictly. If you upgrade your kernel,
+       make sure you also upgrade mountd, because if your export
+       file contains lines with an old inet4 address syntax (i.e.
+       a.b.c or a.b or a), they will get rejected by the new kernel.

        The superblock layout for FFS was changed.  If you have 1.6
        fsck binaries, they will signal a fatal superblock mismatch
