2008-03-08 Daigo Moriwaki <daigo at debian dot org>

	* [mk_html]
	- Added an option --wdoor. In this mode, a rate expected at Shogi
	  Club 24 is calculated from YSS's rating (he is 2400 now). 

2008-03-04 Daigo Moriwaki <daigo at debian dot org>

	* [mk_rate]
	  - If the computed ratings do not stabilize, then mk_rate aborts.
	      $ ./mk_rate dir && ./mk_rate dir > players.yaml 
	    can avoid rewriting the invalid ratings to the file.

2008-02-23 Daigo Moriwaki <daigo at debian dot org>

	* [shogi-server]
	  - A comment is converted to EUC-JP and then written in a log.
	    Note that this conversion guesses the input encoding. Clients
	    are recommended to send EUC-JP compatible strings to the
	    server.

2008-02-21 Daigo Moriwaki <daigo at debian dot org>

	* [util/players-graph.rb]
	  - Released. Draw a chart for a player's rating score.

2008-02-17 Daigo Moriwaki <daigo at debian dot org>

	* [shogi-server]
	  - An illegal teban specified for Floodgate login could crash the
	    server. This issue has been fixed.

2008-02-16 Daigo Moriwaki <daigo at debian dot org>

	* [shogi-server]
	  - Thread.abort_on_exception is now false, meaning that 
	    a thread's abort does not affect the others. 
	  - The uchifuzume check did not generate promoting moves, which
	    could crash the server with illegal moves. This issue has
	    been fixed.

2008-02-14 Daigo Moriwaki <daigo at debian dot org>

	* [shogi-server]
	  - Added a new pairing variation, Swiss-like style. Winners at the
	    previous games (his/her point of view, not the server's) are 
	    paired first, and then the others are matched. This is the 
	    default option now.
	  - Pairing classes are located in a separate source file,
	    pairing.rb. The file is 'load'ed each time to be used,
	    meaning that modifying the code will be applied to a running
	    server.
	  - You can specify a single player who will be out of pairing
	    when there are odd players waiting for Floodgate.

2008-02-13 Daigo Moriwaki <daigo at debian dot org>

	* [shogi-server]
	  - When there are odd players wating for Floodgate, the random
	    pairing deletes the player who has ever played the most games.

2008-02-08 Daigo Moriwaki <daigo at debian dot org>

	* [ml_html]
	  - For the Not-Yet-Rated group, those who have not connected
	    recently are not listed.
	* [shogi-server]
	  - Floodgate's thread checks the current time each 10 secs.

2008-02-05 Daigo Moriwaki <daigo at debian dot org>

	* [mk_rate] [mk_html]
	  - Display not-yet-rated players as well.
	* [mk_html]
	  - Use Yahoo! UI Library.

2008-02-04 Daigo Moriwaki <daigo at debian dot org>

	* [shogi-server] [webserver]
	  - In the daemon mode, if the specified directory was a relative
	    path, the server could fail to start with a permission denied
	    error. This issue has been fixed. The path is interpreted as 
	    an absolute path before switching to daemon. 
	  - In the daemon mode, a wrong process id was written in 
	    '--pid-file'. This issue has been fixed. Also, the pid file
	    will be removed when the server shuts down.

2008-02-03 Daigo Moriwaki <daigo at debian dot org>

	* [shogi-server]
	  - Game names that are recognized as the floodgate mode are now 
	    /^floodgate-\d+-\d+$/.
	  - Floodgate could not schedule the next time when it was the next
	    day. This issue has been fixed.

2008-02-02 Daigo Moriwaki <daigo at debian dot org>

	* [shogi-server]
	  - Implemented a new feature, Floodgate mode, for covenience with
	    public rating games. Now there is a special game "wdoor-900-0".
	    Matching players for that game is scheduled each 30 minitues.

2007-11-03 Daigo Moriwaki <daigo at debian dot org>

	* [mk_rate]
	 - Support Ruby 1.8.6 patch level 111 (or higher) and GSL 1.10 (or higher).
	   It may not work with lower verions. 

2007-09-06 Daigo Moriwaki <daigo at debian dot org>

	* [shogi-server]
	  - The logic to detect Oute-Sennichite was not complete. Both players
	    (checking side and escaping side) may cause Oute-Sennichite. The old
	    logic only cared for the checking player. This issue has been fixed.

2007-06-16  Daigo Moriwaki <daigo at debian dot org>

	* [webserver]
	  - Initial version. This web server is an interface between HTTP and
	    shogi-server. Shogi-server commands will be available over HTTP. As
	    of now %%LIST and %%WHO commands are supported.
	* [mk_rate]
	  - Bumped up GAME_LIMIT (from 10) to 15 because the calculation of
	    rates sometimes went wrong (infinite values).

2007-04-21  Daigo Moriwaki <daigo at debian dot org>

	* [shogi-server]
	  - Implemented `CHALLENGE' command, and the server will respond with
	    `CHALLENGE ACCEPTED'. Note that this command is dummy for this server
	    because it is only available for CSA's official testing server and does
	    not belong to the CSA standard protocol.  Therefor, when clients receive
	    `CHALLENGE ACCEPTED' from this server, they must ignore it.
	  - Show revision in a start up message.

2007-04-01  Daigo Moriwaki <daigo at debian dot org>

	* [shogi-server]
	  - Implemented one of the keepalive protocol in CSA protocol; If clients
	    send LF, the server sends back LF.
	  - More care for socket errors.

2007-03-27  Daigo Moriwaki <daigo at debian dot org>

	* [mk_rate] When there were too few games to rate players (i.e. no
	  player to rate), mk_rate caused an error. Now it no longer shows
	  the error.

2007-03-10  Daigo Moriwaki <daigo at debian dot org>

	* [shogi-server] Sente (gote) was able to move gote's (sente's) hand.
	  That move should be illegal. This issue has been fixed.

2006-11-01  Daigo Moriwaki <daigo at debian dot org>

	* [mk_rate] Skip "abnormal" games, which were finished because of
	  network failure or communication error.  Recently some programs seem
	  to have a lot of tries to connect to the Shogi Server at wdoor for
	  debugging. We should ignore such games for a while to get a meaningful
	  ratings.

2006-10-30  Daigo Moriwaki <daigo at debian dot org>

	* [mk_rate][mk_html]
	  - Put players into "connected" groups in order to
	    show a correct, meaningful rating. In the group, each player has at
	    least a game with other players.
	  - The format of players.yaml was updated.
	* [shogi-server] Followed the new format of players.yaml.
