     * The thumbnail index now supports actions on the currently selected
       thumbnail  (patch by Olof-Joachim Frahm)
+    * feh now supports 'make stat64=1' to access 64bit CIFS shares from 32bit
+      hosts (for 32 <-> 32 or 64 <-> 64 bit, this works anyways)

  * curl     (default 1) - use libcurl to view http:// and similar images
  * debug    (default 0) - debug build, enables --debug
  * help     (default 0) - include help text (refers to the manpage otherwise)
- * xinerama (default 1) - Support Xinerama multiscreen setups
+ * stat64   (default 0) - Support CIFS shares from 64bit hosts on 32bit machines
+ * xinerama (default 1) - Support Xinerama/XRandR multiscreen setups
 
 So, by default libcurl and Xinerama are enabled, while debug is disabled.
