 +      kea-admin now supports dumping MySQL and PostgreSQL lease tables
 +      to CSV file, via a new command "lease-dump".  This is primarily
 +      intended for use as a diagnostic tool.

 +      upgrades available.

 +      DHCPv4 server by default identifies a client using the
 +      client-identifier, if present. The new configuration

 +      behavior, i.e. 'chaddr' field is used to identify the
 +      client instead.

 +930.  [func]          tomek
 +      Statistics Manager is now implemented. There is a new library
 +      libkea-stats that governs statistics collection. Its usage will
 +      be added in the upcoming tickets.
 +      (Trac #3793, git 68e9554ecabfc2a79731eeec1c706522e4d39332)

        Corrected problem in build system whereby specifying an
        installation directory on the "configure" command line that
        included a "+" in the name caused the build to fail.
