+v0.3 2010/09/30
+
+ * New commands \textsubsuperscript and \textsupersubscript added.
+
+ * Fix an "infinite loop" bug added in the last version, triggered
+ when loading the `xltxtra` package with the `[no-sscript]` option.
+
+
+v0.2 2010/09/20
* Add feature to specify the font of the patched footnotemark.
This behaves well with KOMA-Script's `\setkomafont`, as well.
