Nextcloud 13.0.1, 12.0.6 and 11.0.8 available with improved password protection

The web update from 13.0.0 to 13.0.1 did not work for me, due to a database DriverException:

An exception occured in driver: could not find driver in /volume1/web/nextcloud/3rdparty/doctrine/dbal/lib/Doctrine/DBAL/Driver/AbstractMySQLDriver.php:115

See this separate thread for details.
