Automated migrations from rector.php and fractor.php (TCA, Extbase controllers and annotations, ViewHelpers, QueryBuilder, FlexForms, TypoScript conditions). Plugins stay list_type plugins: Rector switched them to content element types, which needs a tt_content migration. That is deferred to the TYPO3 14 step, where list_type is removed.
