by mistake I committed a new readme file yesterday which marks the current state of 0.9.9.7 as "latest". But actual 0.9.9.7 is still under development - so different functions announced for 0.9.9.7 still does not work. Also the "per post" stats are not shown even if you activate them.
But good news: The release should work in spite of everything and comes also with some overdue bugfixes.
I'm sorry for the inconvenience caused to you.
