I don't think this has changed at all.

It sounds like you're looking for a script to run automatically on
the client side at checkout, update, export, commit times. But
Subversion hooks don't do that. Rather, they run automatically on the
server. The pre-commit hook also can't change the transaction that's
in the incoming transaction, and there are no pre-checkout or pre-
update or pre-export hooks. So Subversion hooks won't help you here.

You would have to create the normal file archive manually before
putting it in Subversion, and un-archive it after you take it out of
Subversion. You can write scripts to automate this, but Subversion
won't call them for you.
