+       * [shogi-server]
+         - 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.

 +      * utils/eval_graph.rb:
 +        - Gnuplot 4.6.6 drew evaluation-value lines with a dashed style.
 +          This issue has now been addressed so that solid lines are used.
