Ran into a problem trying to update to version 1.4 by svn, which I have done successfully in the past (svn sw https://omeka.org/svn/tags/1.4).
Upgrade seems to go normally until it hits the Zend stuff, at which point it fails with this error message: UUID mismatch : existing directory 'application/libraries/Zend' was checked out from a different repository. Leaves the site inaccessible.
Is there any cure for this?
