Announcement text given by the package's contributor:
Version 1.09:
Added upper case variants ORDINALstring
etc. (MakeUppercase{ordinalstring{<counter>}} and similar variations
don't work because of the way MakeUppercase expands its argument).
Added facility to store results for later use (to compensate for the
fact that commands like ordinalstring don't work in edef etc)
Some of the language related internals have been changed, and have
been made robust. (If you use extdate in the datetime package, you
will also need to update the datetime package.)
