+================================================
+Deprecation: #91030 - Runtime-Activated Packages
+================================================
+
+See :issue:`91030`
+
+Description
+===========
+
+TYPO3's global configuration option :php:`$GLOBALS['TYPO3_CONF_VARS']['EXT']['runtimeActivatedPackages']` has been marked as deprecated.
+
+The option to register packages during runtime was introduced as
+a work-around to dynamically modify the "extension list" when migrating from TYPO3 v4.5 to TYPO3 v6.x.
+
+However, using this feature has certain limitations:
+
+* Runtime-activated Extensions cannot add their DI configuration
+* Runtime-activated Extensions make every (!) single TYPO3 request much slower just like back in 6.2.0 times
+
+The main use case we know from people was to this functionality to enable e.g. extensions such as "devlog", "mask"/"mask_export" or "extensionbuilder" only on development systems.
+
+
+Impact
+======
+
+Having a TYPO3 system using Runtime Activated Packages functionality
+will trigger a PHP :php:`E_USER_DEPRECATED` error on every TYPO3 request.
+
+
+Affected Installations
+======================
+
+TYPO3 installations having the affected option set in either :file:`typo3conf/LocalConfiguration.php` or :file:`typo3conf/AdditionalConfiguration.php`.
+
+
+Migration
+=========
+
+It is recommended - if this functionality is needed - to use TYPO3
+Console and Composer Mode (with require-dev) to achieve a similar behavior.
+
+If it is critical to have such features, consider modifying the extension in question to deal with TYPO3's Context
+feature to enable / disable functionality for Production environment.
