Many thanks for your clarification !
 
	I think that my short-term needs are satisfied with PHP 7.3+ and lastest PostgreSQL, MySQL and MariaDB databases.
 
	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+
