On HEAD, the teeny version is updated whenever there is a change 
in the interface provided by the kernel to userland, or the 
interface provided to kernel modules.  Examples include adding a 
new system call, adding a new ioctl message, adding a new option 
to an existing call, changing the interface of internal kernel 
functions.  Rarely, the version number may be updated for some 
other reason.

See the cvs log messages for src/sys/sys/param.h for reasons used 
in the past.
