LATEST_VERSION is increased with a complete test when the new version
is released. So the reason is just that I didn't test v1.5.4 on
kernel 3.10 and later.

There is no definite rule, but the new version is usually released
every 2-3 versions of kernel and supports them additionally.

BTW, makedumpfile-1.5.5 will be released at the beginning of December
and it will support kernel 3.10, 3.11 and 3.12 as well.
