+==========================================================
+Deprecation: #86279 - Various Hooks and PSR-15 Middlewares
+==========================================================
+
+See :issue:`86279`
+
+Description
+===========
+
+The new PSR-15-based middleware concept allows for a more fine-grained "hooking" mechanism when enhancing the HTTP
+Request or Response object.
+
+The following hooks have therefore been marked as deprecated:
+
+* :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_fe.php']['tslib_fe-PostProc']`
+* :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_fe.php']['connectToDB']`
+* :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_fe.php']['initFEuser']`
+* :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_fe.php']['checkDataSubmission']`
+* :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/index_ts.php']['preBeUser']`
+* :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/index_ts.php']['postBeUser']`
+* :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_fe.php']['checkAlternativeIdMethods-PostProc']`
+* :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/index_ts.php']['preprocessRequest']`
+
+On top, some middlewares have only been introduced in order to execute these hooks, or due to, and are marked for
+internal use:
+
+* :file:`typo3/cms-core/normalized-params-attribute`
+* :file:`typo3/cms-backend/legacy-document-template`
+* :file:`typo3/cms-backend/output-compression`
+* :file:`typo3/cms-backend/response-headers`
+* :file:`typo3/cms-frontend/timetracker`
+* :file:`typo3/cms-frontend/preprocessing`
+* :file:`typo3/cms-frontend/eid`
+* :file:`typo3/cms-frontend/content-length-headers`
+* :file:`typo3/cms-frontend/tsfe`
+* :file:`typo3/cms-frontend/output-compression`
+* :file:`typo3/cms-frontend/prepare-tsfe-rendering`
+* :file:`typo3/cms-frontend/shortcut-and-mountpoint-redirect`
+
+As these middlewares are marked as internal, it is recommended not to reference them directly, as these might get removed
+in TYPO3 v10.
+
+
+Impact
+======
+
+Making use of one of the hooks in an extension will trigger a PHP :php:`E_USER_DEPRECATED` error.
+
+
+Affected Installations
+======================
+
+TYPO3 instances with extensions using any of the hooks.
+
+
+Migration
+=========
+
+Use a custom PSR-15 middleware instead.
