Backwards-compatibility testing! My initial efforts in July revealed
some serious bugs (which we fixed); unfortunately, I got busy
finishing my thesis and moving to San Francisco and haven't finished
new-client-old-server test infrastructure, but given the bugs we
already found, I would be incredibly uncomfortable releasing 1.5
without a way to automatically verify behavior of old clients with new
servers and vice versa.

I believe they are still working on it. Karl is definitely aware of it now.

I have a scenario in issue 695 that does not work with older servers
when the WC is using sparse directories:
svn up -r123 wc

The good news is that the last time I checked, 1.4.x clients did pass
all tests against trunk servers! This was a few months ago, though.

+1 I'll be running --depth tests against 1.4.x servers to see what
breaks. This is important, we shouldn't release w/o doing it.

code a lot with tigris.org servers as the back-end (which are running
1.3) and I have not ran into any problems.
