I thought the repository format did change (svnadmin 1.3 can't operate
on repositories created with svnadmin 1.4), but the network layer is
still fully compatible, so old & new clients & servers can still
communicate.

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.
