If you look at the irc log from tonight you 'll clearly see that
all I am looking for is documentation for the current state of affairs.

But apparently the server code expects version, not old_version.
Personally I slightly prefer version as it would then become
identical code from just saving the file.

This is inconsistent with section 1.5 of the wiki page on 0.6 that
says the changeset_id attribute should be on the osm tag for diff
upload. So it would be interesting to find out the reason for
this difference.

Ain't that the definition of an API?
