I updated my copy from Edin's collection last week. It's newer than last year's, but I'm struggling to find any form of 'version' in there to know exactly what I have in front of me. So what are you talking about? Update from what, to what, and for which PHP build?
I'm talking about the libtidy version:
php -r "echo tidy_get_release();"
or
php -i | grep libTidy
the official php build's libtidy version is '1st July 2004', which is almost two years old, and thus doesn't have the tidyOptGetDoc() function.
