kolab calendar plugin, what version?

[sporkman]

I'm running the latest stable roundcube (0.9.5) and I'm having issues with getting the latest calendar plugin from the kolab project working (3.1.11): http://git.kolab.org/roundcubemail-plugins-kolab/

I'm pretty lost as to what version of roundcube the plugins are tied to.  3.1.1 mostly works, but the web invitations are broken.  I have an older version that I grabbed as a git snapshot long ago and that mostly works, but I'm trying to get myself to whatever is the "official" release to work with standalone roundcube.  Any idea what to download of all the tarballs on the above page?

You need Roundcube 1.0 for kolab plugins 3.1.x. Wait few days for 1.0-rc or get it from git-master now.

What version of the plugin is appropriate for 0.9.5?  This is a production system, so I'm not interested in a pre-release roundcube.
