Since I am considering installing Chamilo LMS 2.0 when it becomes available (now scheduled mid-November), do you think the following
requirements will be met by then?
composer 2.x
yarn 2.x
Node >= v14
Configuring a virtualhost in a domain, not in a sub folder inside a domain.
A working LAMP/WAMP server with PHP 8.0+
