Not the latest version, but it is the version used by my school (National University) for online classes.

I have only used the client, which is auto-installed when joining a session though the iLinc portal on my university's web site.

What works

So far, everything.

Audio, video, text chat, interactive elements (hand raising, feedback), Application sharing (incoming, outgoing hasn't been tested).

What does not
None

What was not tested
Powerboard, outgoing application sharing, other features not listed above.

Additional Comments

Crashed a couple of times, and took X with it.  Has been fairly stable though.
