+
+ * [shogi-server] Improve timed-up detection.
+ Previously, the server checked if a game got timed up when a player
+ in turn sent no message for a certain amount of time mainly defined
+ by Default_Timeout. If the player sent keep alive frequently, the
+ timed-up detection could be quite delayed.
+ This issue has been addressed. The server now checks timed up with
+ keep alive received as well. Players are notified with TIME_UP not
+ long before games gets timed up.
