as well as the
to manipulate single items in select, group and other types.
In general data given to those custom functions has changed and extensions that rely on this data may

handed over to custom functions may no longer be available at all.

Developers using this API have to debug the data given to custom functions and adapt accordingly.
If the data given is not sufficient it is possible to register own element classes with the
or to manipulate data by adding a custom
. While the current
API will be mostly stable throughout further TYPO3 CMS 7 LTS patch releases, it may however happen
that the given API and data breaks again with the development of the TYPO3 CMS 8 path to make the
FormEngine code more powerful and reliable in the end.
