+- The following methods were changed from "public" to "protected" to match their parent class methods and better align with their uses:
+
+* ``CodeIgniter\Database\MySQLi\Connection::execute()``
+* ``CodeIgniter\Database\MySQLi\Connection::_fieldData()``
+* ``CodeIgniter\Database\MySQLi\Connection::_indexData()``

+* ``CodeIgniter\Test\Mock\MockSecurity.php::sendCookie()``
+
+- To be compatible with the strict inheritance checks of PHP 8.1, the following method signatures were added return types to match their parents' signatures whenever possible:
+
+* ``CodeIgniter\Cookie\Cookie::offsetExists()``
+* ``CodeIgniter\Cookie\Cookie::offsetSet()``
+* ``CodeIgniter\Cookie\Cookie::offsetUnset()``
+* ``CodeIgniter\Cookie\CookieStore::getIterator()``
+* ``CodeIgniter\I18n\Time::__wakeup()``
+* ``CodeIgniter\Test\Filters\CITestStreamFilter::filter()``
+
+- Related to the strict inheritance checks of PHP 8.1, the following session handlers implementing ``SessionHandlerInterface`` have their public methods modified to match the interface:
+
+* ``CodeIgniter\Session\Handlers\ArrayHandler``
+* ``CodeIgniter\Session\Handlers\DatabaseHandler``
+* ``CodeIgniter\Session\Handlers\FileHandler``
+* ``CodeIgniter\Session\Handlers\MemcachedHandler``
+* ``CodeIgniter\Session\Handlers\RedisHandler``
