 ##### Enhancements
 
-* None.
+* New config option "use_safe_filenames" encodes unsafe characters when
+  generating filenames. By default, documentation may receive filenames like
+  "/(_:_:).html". With "use_safe_filenames", the same file will receive the name
+  "_2F_28_5F_3A_5F_3A_29.html" instead.
