#### Breaking Changes
{: #breaking-1-33-0}
+* [<a
href="https://issues.apache.org/jira/browse/CALCITE-5293";>CALCITE-5293</a>]
+ Support general set operators in PruneEmptyRules. The default configuration
of PruneEmptyRules for Set operators has changed: the rules matching scope has
increased.
+
+
Compatibility: This release is tested on Linux, macOS, Microsoft Windows;
using JDK/OpenJDK versions 8 to 18;
Guava versions 19.0 to 31.1-jre;
