Built-in commando plugin! This lets you create runes to allow access to your node from a commando client, which will let you send and receive RPC commands over the lightning network.
Emergency channel backup ("static backup")! Keep track of what peers you have channels with, and in case of node failure ask those peers to close the channel.
zeroconf channels are now possible!! (for whitelisted peers)
iPv6 is now prioritised over ipv4 (great for decentralisation)
LND "internal error" are now treated as warnings, not force close events (reverts to v0.10.0 behavior). Had a pretty bad time with @zerofeerouting because of this, got our funds locked for a week.
Biggest highlights of this release for me
