This does not need an API version change.

You can already get a specific version of a node/way/relation. You append the version number to the url (after a forward slash). For example:
http://www.openstreetmap.org/api/0.6/relation/73447/124
<http://wiki.openstreetmap.org/wiki/API_v0.6#Version:_GET_.2Fapi.2F0.6.2F.5Bnode.7Cway.7Crelation.5D.2F.23id.2F.23version>

The data browser needs to be updated to be able to show specific versions of each node/way/relations. I have been meaning to do it for a while now, just not had the time to get around to it.
