Apache Calcite Avatica 1.9.0 includes various improvements to make it more robust and secure, while maintaining API and protocol compatibility with previous versions.

We now include non-shaded and shaded artifacts, to make it easier to embed Avatica in your application.

There are improvements to the JDBC API, adding support for canceling statements, and improving type conversions and metadata.

The transport is upgraded to use protobuf-3.1.0 (previously 3.0 beta); we have also upgraded Jetty.
