+========================================================================
+Deprecation: #86225 - Classes BaseScriptClass and AbstractFunctionModule
+========================================================================
+
+See :issue:`86225`
+
+Description
+===========
+
+The two classes :php:`TYPO3\CMS\Backend\Module\BaseScriptClass`, also known as
+:php:`t3lib_SCbase` and :php:`TYPO3\CMS\Backend\Module\AbstractFunctionModule`,
+also known as :php:`t3lib_extobjbase` have been marked as deprecated and will be removed
+in TYPO3 v10.
+
+
+Impact
+======
+
+Using one of the classes will trigger a :php:`E_USER_DEPRECATED` error.
+
+
+Affected Installations
+======================
+
+The :php:`BaseScriptClass` has been commonly extended by extensions that add own
+backend modules and did not rely on extbase for that. There is nothing wrong
+with not using extbase, but most of the methods from :php:`BaseScriptClass`
+were unused by own extensions and hard to understand, too.
+
+Class :php:`AbstractFunctionModule` has been extended by some extensions that
+add own sub modules to the Page -> Info or the Page -> Template view.
+
+The extension scanner will find possible usages.
+
+Migration
+=========
+
+A migration is often relatively simple: Extensions that extend :php:`BaseScriptClass`
+should verify which methods and properties are actually used from the parent class. The
+most simple solution is to just copy those over to the own class and remove the
+inheritance. It is good practice to at least change their visibility from :php:`public`
+to :php:`protected` at the same time if possible.
+
+Extensions that extend :php:`AbstractFunctionModule` should do the same. The main `info`
+and `tstemplate` controllers typically only call the methods :php:`init()` and :php:`main()`
+of those classes as entry points, those need to be kept public.
