+ - 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.

+ It (and usiToCsa.rb) did not work with Ruby 1.9.3. This issue
+ has now been fixed.
+ Thanks to Hiraoka-san for debugging.
