of data up to our last backup. In the previous subversion repository, this was r1694->r1777. I'm sorry to all those of you who might have checked out that code, as this will surely cause problems for you. We're currently working to figure out what went wrong, and how to prevent it in the future. git-svn-id: http://svn.openlayers.org/trunk/openlayers@1695 dc9f47b5-9b13-0410-9fdd-eb0c1a62fdaf
