You can update hlstats to use the new format internally by running this SQL command

UPDATE hlstats_PlayerUniqueIds SET uniqueId=SUBSTR(uniqueId, 1, 1)+SUBSTR(uniqueId, 3)*2 WHERE uniqueId REGEXP('[01]:[0-9]+')

And replacing the $uniqueid in hlstats.pl sub getPlayerInfo with this.

                $uniqueid =~ /^\[U:1:(\d+)\]/;
                $uniqueid = $1;

There are few other cosmetic changes such as searching and player display which shouldn't be too difficult to figure out and I am sure the hlstats team will do.
