Every board on your Luos network can deal with multiple containers, and sometimes those containers have to exchange information.
To save some data bandwidth on your network and RAM on your MCU, we added a new feature allowing you to deal with localhost messaging. Localhost messages are not shared into your network and stay in the MCU.
This is a huge deal to improve your Luos system performances, and you should take care to put your applications close to the drivers they are using!
If you need to get all the data into the network, for example for debugging purposes, you can use the VERBOSE_LOCALHOST build flag that disables this feature!
More details about this subject in the messages handling section of our documentation.
