The administrators guide wasn't updated when bug 5245 and bug 4702 were solved. We ought to fix this so the release notes and the documentation does not contradict each other.
Examples from 4.6.0 TAG:
> Note: At this time, SeamlessRDP are not supported by Windows Server 2012
> and Windows Server 2012 R2.
> • Windows Server 2012 and Window Server 2012 R2 does not support
> SeamlessRDP mode
TAG changes look fine.
