Apologies for the slight necro but I felt this thread was the closest
linked to the topic, and since it was of interest to Alice at the time
may be of interest to others too.

I've just finished up and published my NetworkManager rebased article
covering the changes (focusing on behavioural ones):


I do like the idea of my wifi mac being able to be set to random by
default now ... I may well enable that as a default (to handle
trivially the use case of unknown public wifi) and toggle it to
preserve or stable for my known standard connections.

The master-slave style connections (whether vlan, bond, team or
bridge) are much easier to deal with now as well at the command line,
something I'm very happy to see.
