Comment 2 for bug 2072469

It does not, but the version we are using is very old and it:
1) Does not support many features.
2) Clipboard does not work.
3) Many new features are not working (it's a decade old!)

This is the package which kolla-ansible pulls for nova-novncproxy. And so does most nova packages.
The whole novnc of this is a decade old!!.

The above is the novnc repo and just look at the version releases!
