This is all explained quite clearly in the documentation on the
Subversion web site. Each minor release is allowed to change the
working copy format in a non-compatible way (the lower numbered
clients can't safely use it). This simplifies the development of
Subversion but causes a (to me at least) very minor annoyance that all
clients that will use the same working copy must be at the same minor
release. This, however, doesn't stop anyone else who writes
Subversion clients from transparently supporting multiple client
versions simultaneously (and dealing with the complexity that
