In https://www.phpbb.com/downloads/3.3/advanced_update?version=3.3.5

there is "How to update phpBB with the Automatic Update Package." instead of "How to update phpBB with the Advanced Update Package.".

The same goes for https://www.phpbb.com/support/documents.php?mode=install&version=3.2#update_auto where there is "Automatic update package"
