This is the 2.3 Version

Description

In all .htaccess Files, the Apache 2.2 Auth Blocks like

        order allow,deny
        deny from all

have been replaced with this block:

    <IfVersion < 2.4>
        order allow,deny
        deny from all
    </IfVersion>
    <IfVersion >= 2.4>
        Require all denied
    </IfVersion>
