Backwards Compatibility
eXist-db 6.4.1 is backwards binary compatible with all previous 6.x.x releases. This should make upgrading simple with no changes required to XQuery or XSLT application code. For those users migrating from 4.x.x or 5.x.x versions to 6.x.x a full backup and restore of the database will be required and possibly some small changes to XQuery and XSLT application code. Please review previous releases' notes for detailed information.
eXist-db is an open source software project for NoSQL databases built on XML technology. It is classified as both a NoSQL document-oriented database system and a native XML database. Unlike most relational database management systems and NoSQL databases, eXist-db provides XQuery and XSLT as its query and application programming languages.
