While release 4.4.2b1 is primarily a maintenance release that addresses a number
of defects, it does introduce a few new features:
- Keama - Keama is a migration utility that assists in converting ISC DHCP server
configuration files to Kea configuration files. It is found in the keama
subdirectory and includes a README.md file with instructions on how to build it
as well as a manpage on its usage.

- Two new server parameters related to ping checking were added:
1. ping-cltt-secs which allows the user to specify the number of seconds that must
elapse since CLTT before a ping check is conducted.
2. ping-timeout-ms which allows the user to specify the amount of time the server
waits for a ping-check response in milliseconds rather than in seconds.

In order for DHCPINFORMs to be responded to by the server,
they must match to subnets over which the server has authority;
otherwise they will be ignored and logged. To minimize the
impact on logging volume, only the first and every subsequent 100th
occurrence of an ignored DHCPINFORM is logged.
