+
+	* [shogi-server]
+	  - shogi_server/board.rb, game.rb: For hadicapped games, wrong
+	    initial positions were delivered to players and monitors.  This
+	    issue has been fixed. (Closes: #23245) 
+	    Thanks to HIDETCHI for reporting the issue.
+
+2010-09-05  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - shogi_server/login.rb: Enhanced the CSA Login mode.
+	    Logging in the server with the CSA mode, users are now allowed to
+	    specify a turn preference in an enhanced gamename string which
+	    looks like <gamename>-<time>-<time>-<turn>. The first three 
+	    parts are a regular game definition. The last "-<turn>"
+	    part is optional. 
+	    + Without -<turn> (i.e. same as the previous behavior), there
+	    is no turn preference. A user's turn will be defined randomly. 
+	    + <turn> is either "B" for black or "W" for white.
+
+2010-09-04  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - shogi_server/{board,command,game,league,player}.rb
+	    The Buoy behaivor is changed.
+	    + Starting a buoy game, players are notified a starting game
+	      position with the initial position and moves, instread of a
+	      targeting position.
+	    + Players are allowed to start buoy games with specific turns.
+	      ex. %%GAME buoy_foo-1500-0 +
+
+2010-08-05  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - shogi_server/command.rb: Prevent a possible password from be
+	    logged in a log file when players send invalid LOGIN-like commands.
+	    Thanks to Tomoyuki Kaneko for this idea.
+
+2010-08-03  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - sample/{check_file.rb,check_time.rb,check_time2.rb,test_time.rb}:
+	    Added new files to test an issue where mtime of log files was
+	    earlier than system time.
+	  - shogi_server/league/floodgate_thread.rb: SetupFloodgate#start
+	    now returns an instance correctly.
+	  - ../shogi_server.rb, ../shogi_server/util.rb: Refactored
+	    mkdir_for to Mkdir.mkdir_for.
+	  - ../shogi_server/game.rb: mkdir_p will be performed in a global
+	    mutex of ShogiServer::Mkdir.
+
+2010-07-25  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - shogi_server/command.rb: 
+	    + For an unknown error command log, an empty line is no longer logged.
+	    + Commands specific to 81Dojo, starting with '%%%', are just
+	      ignored instead of unknown command errors.
+	  - shogi_server.rb: 
+	    + Refactoring. Added test/TC_logger.rb to test
+	      ShogiServer::Logger class.
+	    + Fixed race condition: creating a new directory to archive
+	      logs may have caused race condition, which ended up with
+	      making the server unavailable. This issue has been fixed. 
+	  - shogi-server:
+	    + Improved fault tolerance of the server.
+
+2010-07-23  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - shogi_server/league/floodgate_thread.rb: When the server run
+	    with DEBUG mode, it ended up with an undefined variable error. 
+	    This issue has been fixed.
+
+2010-07-17  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - shogi_server.rb, shogi_server/board.rb, shogi_server/move.rb
+	    - Refactoring: Board can now move_to() and move_back() a move
+	      instread of deep_copy().
+
+2010-07-11  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - shogi_server/player.rb: Set initial values to BasicPlayer's
+	    instance variables.
+	  - shogi_server/league.rb: Improved performance of
+	    Persistant#get_players. It took about 20 seconds for a large
+	    size of players (5,300 lines in players.yaml). Now it completes in an
+	    instance.
+
+2010-06-22  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - A new command line option: 
+	      --floodgate-names GameStringA[,GameStringB[,...]]
+	    where a game string should be a valid game name such as
+	    floodgate-900-0.  
+	    .
+	    Note: Without this option, no floodgate games are started. If
+	    you want floodgate-900-0 to run, which was default enabled in
+	    previous versions, you need to spefify the game name in this new
+	    option.
+	  - Floodgate time configuration file:
+	    You need to set starting times of floodgate groups in
+	    configuration files under the top directory. Each floodgat
+	    e group requires a correspoding configuration file named
+	    "<game_name>.conf". The file will be re-read once just after a
+	    game starts. 
+	    .
+	    For example, a floodgate-3600-30 game group requires
+	    floodgate-3600-30.conf.  However, for floodgate-900-0 and
+	    floodgate-3600-0, which were default enabled in previous
+	    versions, configuration files are optional if you are happy with
+	    defualt time settings.
+	    File format is:
+	      Line format: 
+	        # This is a comment line
+	        DoW Time
+	        ...
+	      where
+	        DoW := "Sun" | "Mon" | "Tue" | "Wed" | "Thu" | "Fri" | "Sat" |
+	               "Sunday" | "Monday" | "Tuesday" | "Wednesday" | "Thursday" |
+	               "Friday" | "Saturday" 
+	        Time := HH:MM
+	     
+	      For example,
+	        Sat 13:00
+	        Sat 22:00
+	        Sun 13:00
+
+2010-06-01  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - shogi_server/command.rb: Fixed an issue that MONITOR2OFF did not
+	    work. Thanks to HIDECHI and koudayu.
+
+2010-05-10  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - test/*.rb: Improved performance and stability of tests
+	  - shogi_server/player.rb: Help the write_thread to terminate
+
+2010-05-06  Daigo Moriwaki <daigo at debian dot org>
+
+	* [mk_rate]
+	  - Previously mk_rate did not count in draw games. Now a draw game
+	    is considered to weight 0.5 win and 0.5 loss. Respect
+	    Inaniwa-shogi which strategically aims to draw.
+	  - a new command line option, --skip-draw-games. In this mode, draw
+	    games are just ignored as mk_rate previously did.
+
+2010-04-25  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - shogi_server/player.rb:
+	    Log a warning message in a case that a player closes a
+	    connection suddenly.
+
+2010-04-13  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - shogi_server/command.rb:
+	    Equality of MonitorHandler class was wrong. %%MONITOROFF and
+	    %%MONITOR2OFF may cause unexpected behavior. This issue has been
+	    fixed. Thanks to Kota Fujiwara for reporting.
+
+2010-03-07  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - If two sequential moves from a player are identical, the last
+	    one will be ignored and a game is in play. This situation might
+	    happen with human players, especially on slow network,
+	    impatiently sending a move twice. 
+
+2010-02-27  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - The server now provides more accurate time control. Previouslly,
+	    a player's thinking time included a time waiting to get the giant
+	    lock. This may have caused games to time up, especially, during
+	    byo-yomi etc.
+
+2010-01-22  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - Experimental feature: support handicapped games.
+	    Game names that have the following prefixes are recognized as
+	    handicapped games. Turn symbols "+" and "-" mean Uwate (expert)
+	    and Shitate (beginner) respectively (i.e. Uwate players first).
+	    "*" is not available. 
+	    - hclance_
+	    - hcbishop_
+	    - hcrook_
+	    - hcrooklance_
+	    - hc2p_
+	    - hc4p_
+	    - hc6p_
+	    - hc10p_
+
+2010-01-16  Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - shogi_server/command.rb, test/TC_command.rb
+	    Proposal implementation of a new command called MONITOR2{ON,OFF}.
+	    When the MONITOR2ON command is issued by a player, the server
+	    immediately sends the player the entire contents of a record
+	    file of the game, i.e. history of moves and so on, at that time.
+	    Then, the server will forward subsequent moves like they are
+	    appended to the record file.
+	  - Behavior changed: A player monitoring a game with MONITORON will
+	    not receive Game#show again when a gaming player resigns (:toryo).
+
+2010-01-10  Daigo Moriwaki <daigo at debian dot org>
+
+	* Converted the repository from Subversion to Git.
+
+2009-12-26 Daigo Moriwaki <daigo at debian dot org> 
+
+	* [shogi-server]
+	  - The server can now provide multiple floodgate modes such as
+	    floodgate-900-0 and floodgate-3600-0.
+
+2009-12-25 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - shogi-server: The command line option --floodgate-history has
+	    been deprectated. The server will decide history file names such
+	    as 'floodgate_history_900_0.yaml' and
+	    'floodgate_history_3600_0.yaml', and then put them in the top
+	    directory.
+
+2009-12-20 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - shogi_server/player.rb: Added new methods: is_human? and
+	    is_computer?. 
+	    A human player is recommened to use a name ending with '_human'.  
+	    ex. 'hoge_human', 'hoge_human@p1'
+	  - shogi_server/pairing.rb: Added a new class:
+	    StartGameWithoutHumans, which tries to make pairs trying to
+	    avoid a human-human match. This is now enabled instread of the
+	    previous class: StartGame.
+	  - shogi-server, shogi_server/league/floodgate.rb:
+	    Changed the argument of Floodgate.new.
+
+2009-12-04 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - The HUP signal is not supported by Ruby on Windows.
+
+2009-11-11 Daigo Moriwaki <daigo at debian dot org>
+
+	* [mk_rate]
+	  - Added a new command line option: --base-date. You can specify a
+	    base date to calculate rating scores. Games in the `future' are
+	    ignored for the calculation.
+
+2009-11-10 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - The server logs a result of each game to a file named '00LIST',
+	    which will be used to generate players.yaml. If the file does
+	    not exist, the server will create one automatically.
+	    Instruction to use the game result list file:
+	    1. Make a list of game results from exisiting CSA files with
+	       mk_game_results
+	       % ./mk_game_results dir_of_csa_files > 00LIST
+	    2. Run the server. It appends a result of each game to
+	       '00LIST' when the game finishes.
+	    3. From the list of game results, calculate rating scores of
+	       players.
+	       % ./mk_rate 00LIST > players.yaml
+
+2009-11-08 Daigo Moriwaki <daigo at debian dot org>
+
+	* [mk_rate]
+	  - Split a pre-process collecting game results from csa files into
+	    a new command, mk_game_results. Now, Generating players.yaml
+	    requires two steps as follows:
+	      % ./mk_game_results dir_of_csa_files > 00LIST
+	      % ./mk_rate 00LIST > players.yaml
+	      or
+	      % ./mk_game_results dir_of_csa_files | ./mk_rate > players.yaml 
+	    (Closes: #19454)
+
+2009-08-06 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - A experimental new feature, codenamed Buoy: it allows players to
+	    play a game starting with a specified position. First, a player
+	    sets a buoy game with moves to a specific position. Then, two
+	    players can play a new game with the game name.
+	    New commands:
+	    + %%SETBUOY <game_name> <moves> [count]
+	      Set a new buoy game.
+	      ex. %%SETBUOY buoy_foo-900-0 +7776FU 10
+	      ex. %%SETBUOY buoy_foo-1500-0 +7776FU-3334FU
+	      - game_name is a valid game name with a prefix "buoy_".
+	      ex. buoy_foo-900-0
+	      - moves are initial moves from the Hirate position to a
+	      spcific position that you want to start with.
+	      ex. +7776FU-3334FU+8786FU
+	      - count is an optional attribute to tell how many times the
+	      game can be played (default 1). The count is decremented
+	      when the game finishes. If the count reaches zero, the buoy
+	      game is removed automatically by the server.
+	      ex. 10
+	    + %%DELETEBUOY <game_name>
+	      Delete a buoy game. The only owner who set up the game is
+	      allowed to delete it.
+	      ex. %%DELETEBUOY buoy_foo-900-0
+	      - game_name is the buoy game name that was created.
+	    + %%GETBUOYCOUNT <game_name>
+	      Show a current count of the buoy game or -1 for non-existing
+	      games.
+
+
+2009-07-11 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - shogi_server/command.rb: refactored commands out of player.rb.
+
+2009-06-18 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - An emtpy floodgate_history.yaml caused a server error. This
+	    issue has been fixed. 
+	    (Closes: #15124)
+
+2009-06-17 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - If a new game matched between two players is not started within
+	    a certain time (default 120 seconds) (i.e. the agree_waiting or
+	    start_waiting state lasts too long), the Server REJECTs the game.
+	    (Closes: #14425)
+
+2009-06-15 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - When a Gote player AGREEd a new game and then a Sente player
+	    logged out (LOGOUT), the Gote incorrectly received a LOGOUT message 
+	    from the server. Since Gote's state was not AGREEd or STARTed yet,
+	    the Gote should be REJECTed. This issue has been fixed. 
+	    (Closes: #17335)
+
+2009-06-14 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - The Board could not recognize a certain pattern of
+	    Oute-Sennichite. This issue has been fixed.
+	    (Closes: #13966)
+
+2009-03-22 Daigo Moriwaki <daigo at debian dot org>
+
+	* [utils/correct-bug14635.rb]
+	  - Added a new file. This program corrects illegal lines introduced
+	    by the #14635 bug.
+
+2009-03-07 Daigo Moriwaki <daigo at debian dot org>
+
+	* [csa-file-filter]
+	  - Improved performance.
+
+2009-02-15 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - A duplicated comment that is the one of the previous (or older)
+	    move might be erroneously recorded in a csa file. This issue has 
+	    been fixed. (Closes: #15080)
+
+2009-02-11 Daigo Moriwaki <daigo at debian dot org>
+
+	* [utils/csa-filter.rb]
+	  - Added a new file. This program filters CSA files.
+
+2009-02-01 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - The shogi-server records csa files of games in an illegal
+	    format. This issue has been fixed. (Closes: #14635)
+	  - A ##[MONITOR] command for showing a game result such as %TORYO
+	    was not correct. This issue has been fixed.  
+
+2009-01-13 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - It failed to proccess a game result, OuteKaihiMoreWin where a
+	    checked king does not escape. This issue has been fixed.
+
+2009-01-02 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - shogi_server/timeout_queue.rb: the timeout parameter of the
+	    constructor was not respected erroneously. This issue
+	    has been fixed.
+	  - shogi_server/players.rb: When a player was finishing with its
+	    write socket broken, there was a chance that the thread of the
+	    player in the giant lock had to wait for a long time (about 20
+	    seconds), which might cause threads of other players stop and 
+	    time out. (Closes: #14469)
+
+2008-12-30 Daigo Moriwaki <daigo at debian dot org>
+
+	* [mk_html]
+	  - Added a new option: --footer filename, which inserts contents of 
+	    the filename at the bottom of a genrated page. A text specific to 
+	    wdoor should be written by using this option. 
+	    (Closes: #14470)
+	  - It does no more depend on RDoc. RDoc::usage does not work well
+	    (due to RDoc).
+
+2008-12-28 Daigo Moriwaki <daigo at debian dot org>
+
+	* [mk_rate]
+	  - Check kifu files more carefully so that files that contain
+	    incomplete records are skipped.
+	  - mk_rate might have failed to alloc due to out of memory. Now it
+	    consumes less memory (about 200MB instead of 2GB).
+	  - File names can be put into STDIN instead of specifying directory
+	    names in command line arguments.
+	* [csa-file-filter]
+	  - New file. It filters kifu files and is of use for a pre-filter
+	    of mk_rate.
+
+2008-12-13 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - Improved an existance check and etc. of directories specified
+	    by command line options, expecially in case of the daemon mode. 
+	    (Closes: #14244)
+	  - A lotated log file is moved to $topdir/YYYY/MM/DD.
+	    (Closes: #14245)
+
+2008-11-27 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - Added sample/*.sh for command line samples.
+
+2008-11-24 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - Added a new option --floodgate-history, which allows users to
+	    specify a file name that stores the records of games. The
+	    records are taken care of when games are matched.
+
+2008-10-18 Daigo Moriwaki <daigo at debian dot org>
+
+	* [utils/eval_graph.rb]
+	  - Display time control graphs as well.
+	    Thanks to Nishimura-san for this idea.
+	    (Closes: #13678)
+
+2008-10-08 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - Ruby 1.8.7 (or later) must be used. Ruby 1.8.6 is not supported.
+	  - Daemon mode is available.
+	  - shogi_server/piece_ky.rb is again merged with
+	    shogi_server/piece.rb, then has been removed.  
+	  - Added a test case, TC_usi.rb.
+
+2008-06-30 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - Added a new option --player-log-dir, which allows users to log
+	    messages that are received or sent to the wire.
+
+2008-06-28 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - A rating comment line is now written before the first move in a
+	    record file instead of after the last move, which allows other
+	    applications watching a game to recognize players in the middle 
+	    of the game. (Closes #12821)
+	  - If a player, including a monitor, stuck at the time of sending
+	    messages to the wire, which means that the giant lock was locked,
+	    it might have prevented other players from processing until
+	    timeout occurred. This issue has been fixed. (Closes #12555)
+
+2008-06-27 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  -  Pairing players might not have shuffled players because of
+	     poor shuffling algorithm. This issue has been fixed.
+	     (Closes: #12661)
+
+2008-06-25 Daigo Moriwaki <daigo at debian dot org>
+
+	* [players_graph.rb]
+	  - Check invalid arguments. (Closes: #12856)
+
+2008-06-23 Daigo Moriwaki <daigo at debian dot org>
+
+	* [mk_rate]
+	  - Added a new option: --fixed-rate and --fixed-rate-player
+	    whose rate always results in that rate. (Closes: #12800)

+
+	* [shogi-server]
+	  - The source has been splited to multiple sub files.
+	  - The program now depends on rubygems and activesupport.
+	  - The program can reload the source files on the flight, by
+	    sending a HUP signal to the server.
+	  - The server log will be rotated daily.
+
+2008-05-18 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - Last game results (win or lose) of x1 players were not
+	    available on the next game. This issue has been fixed.
+	    Thanks to Tomoyuki Kaneko for debugging.
+	  - For draw games, "'rating" line in a .csa file was 
+	    wrong (meaningless). This issue has been fixed.
+
+2008-05-16 Daigo Moriwaki <daigo at debian dot org>
+
+	* [news]
+	  - The repository has been converted from CVS to Subversion.
+
+2008-05-13 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - Floodgate's thread could cause an error when players.yaml was
+	    cleared by another program (mk_rate). This issue has been 
+	    fixed.
+	  - Give default values to BasicPlayer, which fixed undefined 
+	    method error in Pairing.
+
+2008-05-10 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - The server could not recognize uchifuzume as an illegal move.
+	    This bug has been fixed.
+	  - The server crashed by an undefined method error.
+	    This issue has been fixed.
+
+2008-05-05 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - .csa files will be located in a sub directory such as
+	    "2008/05/05/*.csa". Thease days, we have many games in a day. 
+	    This change will help users browse a file list.
+
+2008-05-03 Daigo Moriwaki <daigo at debian dot org>
+
+	* [mk_html]
+	  - Show players who have accessed in the last 30 minutes with 
+	    different colors.
+
+2008-04-22 Daigo Moriwaki <daigo at debian dot org>
+
+	* [mk_html]
+	  - When YSS was not rated on the wdoor mode, wrong rate24 scores
+	    were displayed. This issue has been fixed. Now YSS absence 
+	    results in "N/A".
+
+2008-04-21 Daigo Moriwaki <daigo at debian dot org>
+
+	* [mk_rate]
+	  - The half-life period is now configurable.
+	    ex $ ./mk_rate --half-life 14 --half-life-ignore 7 <records>
+
+2008-04-12 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - Renamed variables (@id) since they caused Ruby's warning.
+
+2008-04-11 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - Improved a way to handle diferred moves (2008-03-24's change),
+	    based on Tomoyuki Kaneko's patch.
+
+2008-04-01 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - An incorrect LOGIN crashed the server. This issue has been
+	    fixed.
+
+2008-03-24 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - Converting characters for comments in moves caused an error. This 
+	    issue has been fixed.
+	  - If a player moves in the opponent's turn, it is illegal. But the
+	    current CSA protocol does not clearly define a way to tell so to 
+	    the players. This shogi-server internally keeps such a move in a
+	    buffer and replay it when the player of the move gets his/her 
+	    turn.
+
+2008-03-16 Daigo Moriwaki <daigo at debian dot org>
+
+	* [shogi-server]
+	  - Erroneously, Board#to_s's current player was always Black.
+	    It caused wrong determination of sennichite since it did not
+	    care about the current player of a state. This has been fixed.
+	    Thanks Takada-san for reporting this bug.
+
+2008-03-10 Daigo Moriwaki <daigo at debian dot org>
+
+	* [util/players-graph.rb]
+	  - Applied Kaneko-san's patch, which also shows expected-rate24
+	    rates.
+	  - Small PNG gets smaller.
+
+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
-	    prevous games (his/her point of view, not the server's) are 
+	    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,
