Backwards Compatibility

eXist-db 4.6.0 is not binary compatible with previous versions of eXist-db (including earlier 4.5.x releases) 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 - https://exist-db.org/exist/apps/doc/upgrading.xml in the documentation.
