 - The color code output by :ref:`CLI::color() <cli-library-color>` has been changed to fix a bug.
 - To prevent unexpected access from the web browser, if a controller is added to a cli route (``$routes->cli()``), all methods of that controller are no longer accessible via auto-routing.
 - There is a possible backward compatibility break for those users extending the History Collector and they should probably update ``History::setFiles()`` method.
-- The :php:func:`dot_array_search`'s unexpected behavior has been fixed. Now ``dot_array_search('foo.bar.baz', ['foo' => ['bar' => 23]])`` returns ``null``. The previous versions returned ``23``.
-- The ``CodeIgniter::storePreviousURL()`` has been changed to store only the URLs whose Content-Type was ``text/html``. It also affects the behavior of :php:func:`previous_url` and :php:func:`redirect()->back() <redirect>`.

-- HTML helper ``script_tag()`` now uses ``null`` values to write boolean attributes in minimized form: ``<script src="..." defer />``. See the sample code for :php:func:`script_tag`.
-- Added 4th parameter ``$includeDir`` to ``get_filenames()``. See :php:func:`get_filenames`.

 - Exception information logged through ``log_message()`` has now improved. It now includes the file and line where the exception originated. It also does not truncate the message anymore.
     - The log format has also changed. If users are depending on the log format in their apps, the new log format is "<1-based count> <cleaned filepath>(<line>): <class><function><args>"

 - The method signature of ``CodeIgniter\Debug\Exceptions::__construct()`` has been changed. The ``IncomingRequest`` typehint on the ``$request`` parameter was removed. Extending classes should likewise remove the parameter so as not to break LSP.
 - The method signature of ``BaseBuilder.php::insert()`` and ``BaseBuilder.php::update()`` have been changed. The ``?array`` typehint on the ``$set`` parameter was removed.
 - A bug that caused pages to be cached before after filters were executed when using page caching has been fixed. Adding response headers or changing the response body in after filters now caches them correctly.
-- Due to a bug fix, now :php:func:`random_string` with the first parameter ``'crypto'`` throws ``InvalidArgumentException`` if the second parameter ``$len`` is an odd number.
