In 1.4, the working copy format changed, and if you use a working
copy with a Subversion 1.4.x client, it auto-updates the working copy
so that it will only work with Subversion 1.4.x clients from then on.
I don't think there is any way to tell it not to do this.

In 1.4, the repository format also changed, but the repository does
not auto-upgrade to the new format. If you want it, you have to dump
and reload the repository. Also, you can still create 1.3-compatible
repositories using 1.4, if you pass the --pre-1.4-compatible switch
to svnadmin create.

All 1.x Subversion servers and clients should still be able to
communicate with one another over the network protocols.
