[4.2] [IMPORTANT] Made Dependencies Stricter

There is a bug in super closure 1.0.0 that allows composer to select the incorrect version of php parser. This needs patching immediately by fixing the version constraint in laravel.

That is not the desired behaviour. We want class preloader 1.0.2 and super closure 1.0.1.

This will require another 4.2.x tag.
