That's covered in the RELNOTES file in the 3.1.x release:

    Version 3.1.x of the ISC DHCP Distribution includes the following major
    new features:

      - A significantly enhanced Failover protocol implementation, which:
         - Implements MAC Address Affinity to reduce the frequency of
           clients being assigned new IP addresses;
         - Supports the assignment of failover-protected addresses to
           legacy BOOTP clients;
         - Implements a dynamic lease reservation system that provides
           improved accounting of the use of fixed address assignments,
           by allocating fixed addresses out of the pool of dynamic
           leases; and
         - Further improves tools and reduces operator oversight
           necessary for maintaining a functioning system.
      - Support for DHCP Leasequery, and the VIVCO/VIVSO options, which
         makes easy and comfortable integration with DOCSIS devices and
         the environment in which they are used.
      - Management of class and subclass statements via OMAPI.
      - Several server configuration options related to dynamic DNS
         behavior
      - Other new configuration functions, including "execute()",
        which runs a shell command from within a dhcpd or dhclient
        configuration file
