#### Breaking Changes
{: #breaking-1-43-0}
+* [<a
href="https://issues.apache.org/jira/browse/CALCITE-7580";>CALCITE-7580</a>]
+ Remove Gandiva dependency from Arrow adapter. Arrow adapter projection and
+ filter evaluation now run in Java, and the `arrow-gandiva` dependency is no
+ longer included in the Arrow module or BOM.
+
+* [<a
href="https://issues.apache.org/jira/browse/CALCITE-7712";>CALCITE-7712</a>]
+`ReflectiveSchema.Factory` requires the class operand to explicitly use the new
+`ReflectiveSchema.Input` annotation. If the annotation is not present the
+creation will fail with `IllegalArgumentException: class X is not annotated
@Input`.
+
+* [<a
href="https://issues.apache.org/jira/browse/CALCITE-7713";>CALCITE-7713</a>]
+Class loading from model files has been disabled by default. Any attempt to
load
+classes from model files will lead to `SecurityException` unless an appropriate
+pattern is set in `calcite.model.classes.allowed` system property.
