I think we normally don't include information about specific versions in 
the man pages included in that version; we just describe how that 
specific version works.  (An exception might be something like, "Users 
upgrading from Xen N.M should...", but that wouldn't apply here.)  
Information about specific versions would be included in the wiki or 
other on-line howtos, which are meant to cover multiple versions.
