+* Fixed that Routes would raise NameErrors if a controller component contains characters that are not valid constant names #733 [Nicholas Seckar]
+
 * Added PATH_INFO access from the request that allows urls like the following to be interpreted by rails: http://www.example.com/dispatcher.cgi/controller/action -- that makes it possible to use rails as a CGI under lighttpd and would also allow (for example) Rublog to be ported to rails without breaking existing links to Rublog-powered blogs. #728 [Jamis Buck]
 
 * Fixed that caching the root would result in .html not index.html #731 [alisdair]
