Version of Superfish Library

In my eyes there is something to be clarified:

On the one hand the release notes mention the superfish library has to be updated if coming from superfish project version 1.9 and older.

On the other hand the link on the project homepage points to an older superfish library (older than the superfish 1.9 project).

So please add the superfish library version to be updated to, maybe update the project homepage, too.
