+================================================================================
+Deprecation: #84338 - Protected methods and properties in TableController
+================================================================================
+
+See :issue:`84388`
+
+Description
+===========
+
+This file is about third party usage (consumer that call the class as well as
+signals or hooks depending on it) of :php:`TYPO3\CMS\Backend\Controller\Wizard\TableController`.
+
+A series of class properties has been set to protected.
+They will throw deprecation warnings if called public from outside:
+
+* [not scanned] :php:`$content`
+* :php:`$inputStyle`
+* :php:`$xmlStorage`
+* :php:`$columnsOnly`
+* :php:`$numNewRows`
+* :php:`$colsFieldsName`
+* [not scanned] :php:`$P`
+* :php:`$TABLECFG`
+* :php:`$tableParsing_quote`
+* :php:`$tableParsing_delimiter`
+
+All methods not used as entry points by :php:`TYPO3\CMS\Backend\Http\RouteDispatcher` will be
+removed or set to protected in v10 and throw deprecation warnings if used from a third party:
+
+* [note scanned] :php:`main()`
+* :php:`tableWizard()`
+* :php:`getConfigCode()`
+* :php:`getTableHTML()`
+* :php:`changeFunc()`
+* :php:`cfgArray2CfgString()`
+* :php:`cfgString2CfgArray()`
+
+
+Impact
+======
+
+Calling one of the above methods or accessing one of the above properties on an instance of
+:php:`TableController` will throw a deprecation warning in v9 and a PHP fatal in v10.
+
+
+Affected Installations
+======================
+
+The extension scanner will find most usages, but may also find some false positives. The most
+common property and method names like :php:`$content` are not registered and will not be found
+if an extension uses that on an instance of :php:`TableController`. In general all extensions
+that set properties or call methods except :php:`mainAction()` are affected.
+
+
+Migration
+=========
+
+In general, extensions should not instantiate and re-use controllers of the core. Existing
+usages should be rewritten to be free of calls like these.
