Rintel: NetworkManager 1.12, ready to serve your networking needs

Lubomir Rintel has a look at the NetworkManager 1.12 release on his blog. There are lots of new features, including WiFi improvements (FILS, Wake on WLAN, IWD), colored nmcli output, removal of some unloved code, and checkpoint/restore:"One of the lesser known goodies provided by NetworkManager is the checkpoint/restore functionality. It allows the user to roll back to a working network configuration if any changes render a machine inaccessible over a network.The user needs to define a checkpoint first, then conduct the potentially dangerous changes and finally confirm that the changes didn't disrupt connectivity. A checkpoint is essentially a snapshot of an active network configuration along with a timer. Should the changes cause a networking outage, the timer expires before the user can confirm success and the changes are reverted, hopefully restoring connectivity."
