2.2.0

This minor release provides the following enhancements:

• Document rows can now be read via MarkLogic search queries.
• Document rows can also be written to MarkLogic, thereby allowing for copy operations that read document rows from one database and write them to another database.
• Now depends on the MarkLogic Java Client 6.5.0 release, which eliminates some security vulnerabilities via upgrades to OkHttp and Jackson.
