What features are included with the builds from the repository ?  are most features such as MQTT default now  and are there any features that would require building from source to be enabled. 
Thanks
			
			
			
				All of the features are enabled on most systems. Some of them are packaged into separate packages (e.g. reporting) or mqtt.
There are some exceptions, you can check them in the version-specific configs: https://github.com/netxms/packages-deb/tree/stable-5.1/config
