Breaking: #92678 - CSS class checkbox-invert removed

See forge#92678


FormEngine used to have a class checkbox-invert for the styling of an item with enabled flag invertStateDisplay. Now the checkbox value itself is inverted. Therefore the class has been removed as it is not needed any more.


Using the class doesn't have any effect on styling anymore.

Affected Installations

Standard installations of TYPO3 are not affected. Only installations that use the class checkbox-invert for customizations are affected.


There is no migration required if only the invertStateDisplay configuration is used. If CSS styling or JavaScript in the backend relies on the class checkbox-invert present custom code needs to be added to make it available again.
