+ - When a non-rated player participates in Floodgate, the following exception
+ was thrown and a Floodgate game would not start:
+ undefined method `[]' for nil:NilClass
+ ["/home/shogi-server/www/x/shogi_server/pairing.rb:499:in `block
+ in calculate_diff_with_penalty'"
+ This issue has been resolved. Only players who have player ID
+ (i.e. those who log in with valid password) are now allowed to
+ participate in Floodgate as the spec web page
+ [http://shogi-server.sourceforge.jp/rating.html] describes.

+
+ * Ruby 2.0:
+ - Ruby 2.0.0 or later is recommended to use with shogi-server
+ since Ruby 1.8 reached its End-of-Life on the end of July, 2014.
+ * [shogi-server]
+ - Addressed a warning of duplicated range in a regular expression.

+ - A player, attempting to login with the current live player
+ stalling for more than a day, can forcibly override the current
+ player.
+ - Kifu record files now includes rating scores of players at the
+ time when games start. Previously, for rating games, a record
+ file includes player IDs of both players with a line starting with
+ "'rating". Now it also shows rating scores for players who have
+ valid scores. The formats for black and white players are as
+ follows:
+ 'black_rate:<player_id>:<score>
+ 'white_rate:<player_id>:<score>
+ A sample output:
+ 'rating:Test_sente+275876e34cf609db118f3d84b799a790:Test_gote+275876e34cf609db118f3d84b799a790
+ 'black_rate:Test_sente+275876e34cf609db118f3d84b799a790:2763.0
+ 'white_rate:Test_gote+275876e34cf609db118f3d84b799a790:2345.0

+
+ * [mk_rate]
+ - Added a new option, --abnormal-threshold n:
+ Games that end with the 'abnormal' status are counted in
+ win/lost games for the rating calculation if a game plays more
+ than n plies. Otherwise (or if n is zero), abnormal games are
+ counted out of rating games.

+
+ * [webserver]
+ - 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)".

+ USI engine to connect to the Shogi-server.
+ - bin/usiToCsa is a sample wrapper script.
