I have released version 1.6.0. Apart from supporting various additional standard and non-standard JOIN constructs, there is now also full support for the SQL standard MERGE statement and MySQL's ON DUPLICATE KEY variant thereof. A great number of API enhancements have been added, which improve the usability of jOOQ. The Ingres database is now also supported.
