  Mainly that it's no longer a hack pretending to be RADIUS.  It's just 100% DHCPv4.

  Other improvements are that complex structures are now trivial.  They're used much \
more in DHCP than in RADIUS.

  The server now supports structures in dictionaries (it's not perfect, but it \
works).  It will then automatically decode the structures into attributes.  The \
structures can contain bit fields, too.  It all Just Works.

  Not in v4.  Pretty much everything easy.

  v4 also supports an experimental ISC DHCP module.  It will read common (i.e. \
simple) ISC files to define options, and implement the policies:

  I did a check against Kea DHCP the other day.  FreeRADIUS v4 is 2/3 the size of Kea \
in code.  But it supports more protocols, more databases, it has a real policy \
language, and it's more configurable.
