IMHO when someone opens an UMO for the first time he sees the latest
version of the UMO only. If new version of this UMO created after his last
visit, he will still see the version he "subscribed" initially.
In our previous discussion
there is a statement:
The important point here is that EACH user of the UMO decides for
himself to use new version or not.
