- TYPO3\- CMS\ - Backend\ - Form\ - Element\ - Abstract - Form - Element->get - Clipboard - Elements - ()

The following property has been removed:
- TYPO3\- CMS\ - Backend\ - Form\ - Element\ - Abstract - Form - Element->clipboard 
The following hook interface has been removed and registered hooks in 
        db are no longer called:
- \TYPO3\- CMS\ - Backend\ - Form\ - Database - File - Icons - Hook - Interface 
TCA wizards registered as 
        user no longer receive the element HTML by reference, so they can no longer change
given HTML string of a given element.
Impact
Using above methods, properties and hooks will result in fatal PHP errors or fail silently.
Affected Installations
Check extensions for usages of above methods and especially implementations of the hook interface.
Migration
The methods have been partially moved to the 
        Tca data provider and merged to the two
FormEngine elements 
        Group and 
        Select. Those can be
changed and extended via FormEngine's internal 
        Node and data provider resolvers.
