Breaking: #88427 - jsfunc.evalfield.js has been removed¶
See Issue #88427
jsfunc.evalfield.js responsible for form value evaluation and validation has been removed. This job is
now done by
TYPO3/CMS/Backend/FormEngineValidation since TYPO3 7.4.
Extensions still relying on this file and its API will stop working.
All installations with third party extensions using this API are affected.
In most cases no migration is necessary, unless this API is used in a custom built form. In such case, migrate to FormEngine API to automatically use the new API.
