+### core_reportbuilder
+
+#### Added
+
+- The base entity class now implements a default `initialise` method, that will automatically call each of the following methods to load entity report data:
+
+  * `get_available_columns()`
+  * `get_available_filters()`
+  * `get_available_conditions()`
+
+  This change allows for a lot of boilerplate to be removed from report entity classes
