I'm yet to come across old_version in the server code.

The version check (that was there when I started working on the code)  
takes the current version number that the client has and checks to see  
if that is the same as the version that is stored. If it is not the  
same, then a OSM::APIVersionMismatchError is raised.

This information is available on the API 0.6 wiki page:

In the code changes I done today, I'm also exposing the changeset_id  
for every node, way and relation. JOSM should use the particular  
changeset for that particular upload, rather than the downloaded one.
