The updated 5.0 AdminPresentation processor is largely backwards compatible, but there is one case that will require some simple code changes.
If you have custom domain that only utilizes field-level AdminPresentation, and does not specify the
then you may find that some tabs are rendered in an unexpected order. The solution is to simply provide a
for each of these fields. Alternatively, you could migrate the AdminPresentation strategy that utilizes AdminPresentationClass's
Tab and Group structure. See the following document for further details: AdminPresentation.
