Apache Calcite Avatica 1.15.0 is a small release that fixes a regression causing error messages to not be propagated to clients. There is also a minor update to the docker release script to automate the upload of release artifacts and build promotion. See the list of [bug fixes and new features]({{ site.baseurl }}/docs/history.html#v1-15-0) for more information.
Consumers of Avatica are encouraged to skip the 1.14.0 release and upgrade directly to 1.15.0 due to the aforementioned regression.
