+
+ * [shogi-server]
+ - shogi_server/pairing.rb, player.rb:
+ Simplify estimated rate of unrated players (less memory).
+ - Enhanced syntax of Floodgate time configuration file.
+ Now it supports "set sacrifice <player_id>"; it sets a
+ sacrificed player for a specific Floodgate game.
+ ex. set sacrifice gps500+e293220e3f8a3e59f79f6b0efffaa931

+
+ * [shogi-server]
+ - Added a new pairing method, ShogiServer::ExcludeUnratedPlayers,
+ which filters out unrated players.
+ - Enhanced syntax of Floodgate time configuration file.
+ Now it supports "set pairing_factory <function_name>"; it sets a
+ factory function name generating a pairing method which will be

+
+ * [shogi-server]
+ - shogi_server/league/floodgate.rb: Improved robustness against
+ empty file under ruby 1.9.3p194
+ - shogi-server:
+ - Previously, reloading in daemon mode failed on
+ ruby 1.9.3p194. This issue has been fixed.
+ - Listen on only IPv4 explicitly. Under ruby 1.9.3p194, without
+ any bind addresses, ruby attempts to listen on both "0.0.0.0"
+ and "::". Specifying "::" on Linux leads to listen on both IPv4
+ and IPv6, which results in a warning message saying "Address
+ already in use - bind(2)".
+ * [mk_game_results]
+ - Fixed for reading Japanese comments under ruby1.9.3p194.
+ * mk_rate-from-grep, mk_rate-grep:
+ - Removed files that are no longer used.
+
+2013-11-23 Daigo Moriwaki <daigo at debian dot org>
+
+ * [mk_rate]
+ - gsl library may be provided as a gem
+ - Now duplicated inputs are checked and skipped.
+ * test/TC_floodgate.rb
+ - Improved randomness check so that it works on Ruby 2.0.0 as well
+
+2013-11-04 Daigo Moriwaki <daigo at debian dot org>
+
+ * [mk_rate]
+ - Added a new option, --ignore, which is imported from
+ mk_rate-from-grep.
+ * [mk_game_results]
+ - Flush after each output line.
+ * Rleased: Revision "20131104"

+
+ * [shogi-server]
+ - shogi_server/{game,time_clock}.rb:
+ When StopWatchClock is used, "Time_Unit:" of starting messages
+ in CSA protocol supplies "1min".
+
+2013-04-07 Daigo Moriwaki <daigo at debian dot org>
+
+ * [shogi-server]
+ - shogi_server/{game,time_clock}.rb:
+ Adds variations of thinking time calculation: ChessClock
+ (current) and StopWatchClock (new).
+ StopWatchClock, which is usually used at official games of human
+ professional players, is a clock where thiking time less than a
+ miniute is regarded as zero.
+ To select StopWatchClock, use a special game name with "060"
+ byoyomi time. ex. "gamename_1500_060".

+
+ * [shogi-server]
+ - %%FORK command: %%FORK <source_game> [<new_buoy_game>] [<nth-move>]
+ The new_buoy_game parameter is now optional. If it is not
+ supplied, Shogi-server generates a new buoy game name from
+ source_game.
+ - command.rb: More elaborate error messages for the %%GAME command.

+
+ * [shogi-server]
+ - New pairing algorithm: ShogiServer::Pairing::LeastDiff
+ This pairing algorithm aims to minimize the total differences of
+ matching players' rates. It also includes penalyties when a match
+ is same as the previous one or a match is between human players.
+ It is based on a discussion with Yamashita-san on
+ http://www.sgtpepper.net/kaneko/diary/20120511.html.
+
+2013-02-23 Daigo Moriwaki <daigo at debian dot org>
+
+ * [shogi-server]
+ - New command: %%FORK <source_game> <new_buoy_game> [<nth-move>]
+ Fork a new game from the posistion where the n-th (starting from
+ one) move of a source game is played. The new game should be a
+ valid buoy game name. The default value of n is the position
+ where the previous position of the last one.
+ - The objective of this command: The shogi-server may be used as
+ the back end server of computer-human match where a human player
+ plays with a real board and someone, or a proxy, inputs moves to
+ the shogi-server. If the proxy happens to enter a wrong move,
+ with this command you can restart a new buoy game from the
+ previous stable position.
+ ex. %%FORK server-denou-14400-60+p1+p2+20130223185013 buoy_denou-14400-60

+
+ * [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.

+
+ * [shogi-server]
+ - shogi_server/{board,command,game,league,player}.rb
+ The Buoy behavior is changed.
+ + Starting a buoy game, players are notified a starting game
+ position with the initial position and moves, instead of a
+ targeting position.
+ + Players are allowed to start buoy games with specific turns.
+ ex. %%GAME buoy_foo-1500-0 +
