+## Support for Legacy Inheritance
+
+The migration from JavaScript to TypeScript was a breaking change because the previous prototype based inheritance was incompatible with ES6 classes.
+`Core.enableLegacyInheritance()` was added in an effort to emulate the previous behavior to aid in the migration process.
+
+This workaround was unstable at best and was designed as a temporary solution only.
+[WoltLab/WCF#5041](https://github.com/WoltLab/WCF/pull/5041) removed the legacy inheritance, requiring all depending implementations to migrate to ES6 classes.
