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 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.
