 *SVN*
 
+* Fixed Request#remote_ip in testing #1251 [bitsweat]
+
 * Fixed that compute_public_path should recognize external URLs, so image_tag("http://www.example.com/images/icon.gif") is not prefixed with the relative url path #1254 [victor-ronr-trac@carotena.net]
 
 * Added support for descending year values in DateHelper#select_year, like select_year(Date.today, :start_year => 2005, :end_year => 1900), which would count down from 2005 to 1900 instead of the other way #1274 [nwoods@mail.com]
