 ### Added
 
-* Added support for the mixed type
+* [PHP 8.0] Added support for the mixed type. This means `mixed` types are now parsed as an
+  `Identifier` rather than a `Name`.
+* [PHP 8.0] Added support for catching without capturing the exception. This means that
+  `Catch_::$var` may now be null.
