Parental v1.5.0 introduces three new features for Single Table Inheritance in Laravel: types can now transition to other types with the become() method, you can use integer columns instead of strings, and new eager-loading helpers like loadChildren() make it easy to load relationships across your inheritance hierarchy.

Tighten

Parental v1.5.0 introduces three major features for Single Table Inheritance in Laravel. The become() method enables type transitions between model classes while triggering appropriate events. Integer type columns are now supported as an alternative to strings for database optimization. New eager-loading helpers (loadChildren(), childrenWith()) simplify loading relationships across inheritance hierarchies, automatically grouping models by type and executing efficient queries for each group.
