+Breaking: #82426 - ExtJS and ExtDirect removal
+==============================================
+
+See :issue:`82426`
+
+Description
+===========
+
+ExtJS and ExtDirect support has been removed from the core (TYPO3 Backend).
+ExtJS Javascript is not loaded now in TYPO3 Backend.
+ExtDirect classes were removed without substitution.
+
+
+Removed classes:
+----------------
+
+* :php:`TYPO3\CMS\Backend\Tree\ExtDirectNode`
+* :php:`TYPO3\CMS\Backend\Tree\Pagetree\Commands`
+* :php:`TYPO3\CMS\Backend\Tree\Pagetree\DataProvider`
+* :php:`TYPO3\CMS\Backend\Tree\Pagetree\ExtdirectTreeCommands`
+* :php:`TYPO3\CMS\Backend\Tree\Pagetree\ExtdirectTreeDataProvider`
+* :php:`TYPO3\CMS\Backend\Tree\Renderer\ExtJsJsonTreeRenderer`
+* :php:`TYPO3\CMS\Backend\Tree\Pagetree\PagetreeNode`
+* :php:`TYPO3\CMS\Backend\Tree\Pagetree\PagetreeNodeCollection`
+* :php:`TYPO3\CMS\Core\ExtDirect\ExtDirectApi`
+* :php:`TYPO3\CMS\Core\ExtDirect\ExtDirectRouter`
+* :php:`TYPO3\CMS\Workspaces\Hooks\PagetreeCollectionsProcessor`
+
+
+Removed methods:
+----------------
+
+* :php:`TYPO3\CMS\Backend\Tree\Pagetree\ExtdirectTreeDataProvider->getNodeTypes()`
+* :php:`TYPO3\CMS\Backend\Tree\Pagetree\ExtdirectTreeDataProvider->loadResources()`
+* :php:`TYPO3\CMS\Core\Page\PageRenderer->setExtJsPath()`
+* :php:`TYPO3\CMS\Core\Page\PageRenderer->getExtJsPath()`
+* :php:`TYPO3\CMS\Core\Page\PageRenderer->addExtOnReadyCode()`
+* :php:`TYPO3\CMS\Core\Page\PageRenderer->addExtDirectCode()`
+* :php:`TYPO3\CMS\Core\Page\PageRenderer->loadExtJS()`
+* :php:`TYPO3\CMS\Core\Page\PageRenderer->enableExtJsDebug()`
+
+
+Removed interfaces:
+-------------------
+
+* :php:`TYPO3\CMS\Backend\Tree\Pagetree\CollectionProcessorInterface`
+* :php:`TYPO3\CMS\Backend\Tree\EditableNodeLabelInterface`
+* :php:`TYPO3\CMS\Backend\Tree\DraggableAndDropableNodeInterface`
+
+Impact
+======
+
+JS code relying on ExtJS will stop working.
+PHP code relying on ExtDirect classes being available will now throw a fatal error.
+
+
+Affected Installations
+======================
+
+All installations having extensions relying on ExtJS being loaded or using ExtDirect API.
+
+
+Migration
+=========
+
+JS code relying on ExtJS has to be reworked to not use ExtJS or to load ExtJS from custom extension.
+PHP code related to ExtDirect should be changed to regular Backend AJAX routing.
