back-end data engines, and includes an SQL parser and, as a
sub-project, the Avatica JDBC driver.

This release comes three months after 1.19.0. It includes more than
130 resolved issues, comprising of a few new features as well as
general improvements and bug-fixes. It includes support for
anti-joins, recursive queries, new functions, a new adapter, and many
more bug fixes and improvements.
