Backwards Compatibility

eXist-db 5.0.0-RC6 is not binary compatible with previous versions of eXist-db (including earlier 5.0.0 Release Candidates) because of new BLOB Store, which required changes to the collections.dbx and Journal. Before upgrading to this version of eXist-db, you MUST perform a full backup and restore. Users who are upgrading should always consult the Upgrading Guide in the documentation.
