Nope, it was only a security fix.

(See the CHANGES file for details.)

I think hotcopy is still the most convenient way, if you recompile APR
as described in issue #1819.

If you can afford to invest a little bit of time (3-5 hours), you
might want to look at contrib/server-side/backup-recipe.sh in the
Subversion tree. That's a sample shell script demonstrating a
backup/restore mechanism. You'd have to write "real" scripts based on
the code in there, but the examples are extensively commented.

(If you do this, and your scripts are general enough, please post them
to the dev@ list, by the way.)

I don't know. If they up their 'http-timeout' parameters in their
~/.subversion/servers files, does the problem go away?

Oh wait, you said this is happening even with file:// ??? How can
there even be a "timeout" error with file:// access, hmmm...

What are the exact errors people are seeing?
