 +      * [shogi-server]
 +        - Addressed Ruby incompatibility on ShogiServer::Usi::alphabetToDan.
 +          It (and usiToCsa.rb) did not work with Ruby 1.9.3. This issue
 +          has now been fixed.
 +          Thanks to Hiraoka-san for debugging.

+       * utils/eval_graph.rb:

+           This issue has now been addressed so that solid lines are used.
