 - **Image:** The ``ImageMagickHandler`` has been rewritten to rely solely on the PHP ``imagick`` extension.
 - **Image:** Added ``ImageMagickHandler::clearMetadata()`` method to remove image metadata for privacy protection.
 - **ResponseTrait:** Added ``paginate``` method to simplify paginated API responses. See :ref:`ResponseTrait::paginate() <api_response_trait_paginate>` for details.
-- **Session:** Added ``persistent`` config item to redis handler.
+- **Session:** Added ``persistent`` config item to ``RedisHandler``.
+- **Session:** Added connection persistence for Redis and Memcached session handlers via ``PersistsConnection`` trait, improving performance in worker mode by reusing connections across requests.
 - **Time:** added methods ``Time::addCalendarMonths()`` and ``Time::subCalendarMonths()``
 - **Time:** Added ``Time::isPast()`` and ``Time::isFuture()`` convenience methods. See :ref:`isPast <time-comparing-two-times-isPast>` and :ref:`isFuture <time-comparing-two-times-isFuture>` for details.
-- **View:** Added the ability to override namespaced views (e.g., from modules/packages) by placing a matching file structure within the **app/Views/overrides** directory. See :ref:`Overriding Namespaced Views <views-overriding-namespaced-views>` for details.
 - **Toolbar:** Fixed an issue where the Debug Toolbar was incorrectly injected into responses generated by third-party libraries (e.g., Dompdf) that use native PHP headers instead of the framework's Response object.
+- **View:** Added the ability to override namespaced views (e.g., from modules/packages) by placing a matching file structure within the **app/Views/overrides** directory. See :ref:`Overriding Namespaced Views <views-overriding-namespaced-views>` for details.
+- **Worker Mode:** Added experimental FrankenPHP Worker Mode support, allowing CodeIgniter to handle multiple HTTP requests within the same PHP process for 2-3x performance improvements. See :doc:`Worker Mode </installation/worker_mode>` for details.
 
 Commands
 ========
 
+- Added ``php spark worker:install`` command to generate FrankenPHP worker mode files (Caddyfile and worker entry point).
+- Added ``php spark worker:uninstall`` command to remove worker mode files.
+
 Testing
 =======
 
 Database
 ========
 
+- **BaseConnection:** Added ``ping()`` method to check if the database connection is still alive. Postgre uses native ``pg_ping()``, other drivers use ``SELECT 1``.
 - **Exception Logging:** All DB drivers now log database exceptions uniformly. Previously, each driver had its own log format.

 *******
 
+- **Boot:** Added ``Boot::bootWorker()`` method for one-time worker initialization.
+- **CodeIgniter:** Added ``CodeIgniter::resetForWorkerMode()`` method to reset request-specific state between worker requests.
+- **Config:** Added ``app/Config/WorkerMode.php`` for worker mode configuration (persistent services, garbage collection).
 - **Cookie:** The ``CookieInterface::EXPIRES_FORMAT`` has been changed to ``D, d M Y H:i:s T`` to follow the recommended format in RFC 7231.
+- **DatabaseConfig:** Added ``Config::validateForWorkerMode()`` and ``Config::cleanupForWorkerMode()`` methods for database connection management in worker mode.
+- **Events:** Added ``Events::cleanupForWorkerMode()`` method.
 - **Format:** Added support for configuring ``json_encode()`` maximum depth via ``Config\Format::$jsonEncodeDepth``.
 - **Paths:** Added support for changing the location of the ``.env`` file via the ``Paths::$envDirectory`` property.
+- **Services:** Added ``Services::resetForWorkerMode()`` and ``Services::validateForWorkerMode()`` methods.
 - **Toolbar:** Added ``$disableOnHeaders`` property to **app/Config/Toolbar.php**.

 ``autoloader``        PSR-4 autoloading configuration. Safe to persist as class maps don't change.
 ``locator``           File locator for finding framework files. Caches file paths for performance.
 ``exceptions``        Exception handler. Stateless, safe to reuse.
-``logger``            Logger instance. Maintains file handles for efficient logging.
-``timer``             Performance timer. Reset internally per request.
 ``commands``          CLI commands registry. Only used during worker startup.
 ``codeigniter``       Main application instance. Orchestrates the request/response cycle.
 ``superglobals``      Superglobals wrapper. Properly isolated per request internally.
