+Breaking: #82572 - RDCT functionality removed
+=============================================
+
+See :issue:`82572`
+
+Description
+===========
+
+The short-link / redirect functionality based on the GET parameter `RDCT` of TYPO3 Frontend requests
+has been removed from TYPO3.
+
+Along, all functionality related to evaluating `RDCT` is not evaluated anymore.
+
+The following PHP methods have been removed:
+
+* TypoScriptFrontendController->sendRedirect()
+* TypoScriptFrontendController->updateMD5paramsRecord()
+* GeneralUtility::makeRedirectUrl()
+
+The eighth property of the constructor of TypoScriptFrontendController is not evaluated anymore,
+also the public property `TSFE->RDCT` is removed as it is not set anymore.
+
+The corresponding database table `cache_md5params` has been dropped.
+
+Substitution logic can be found in the TER extension `rdct`.
+
+
+Impact
+======
+
+When calling TYPO3 Frontend via `index.php&RDCT=myhash` the RDCT GET parameter is not evaluated
+anymore.
+
+Calling :php:`$TSFE->sendRedirect()`, :php:`$TSFE->updateMD5paramsRecord()` and
+:php:`GeneralUtility::makeRedirectUrl()` will result in a fatal PHP error.
+
+Accessing the now non-existent property :php:`$TSFE->RDCT` will trigger a PHP notice, as well
+as setting up a new instance of `TypoScriptFrontendController` with an eighth parameter.
+
+Accessing the database table `cache_md5params` will also lead to unexpected results as this table
+does not exist in new installations anymore.
+
+
+Affected Installations
+======================
+
+Any TYPO3 instance handling data via the `cache_md5params` database table or creating short links
+via `&RDCT` hashes.
+
+
+Migration
+=========
+
+The TER extension `rdct` contains all previous functionality handled via a simple hook. An upgrade
+wizard within the Install Tool will check if the database table is filled and downloads the extension
+from TER.
+
+It is recommended to use a third-party short-url or redirect extension which provides a richer feature
+set.
