title: Bump litep2p to 0.16.0
doc:
- audience: Node Dev
description: |-
Bump litep2p to 0.16.0, which adds the Kademlia client-server mode and fixes
the panics around local provider records in the Kademlia memory store.
The litep2p backend handles the new `KademliaEvent::PeersDiscovered` by reporting
the peers through `Event::PeerRoutingTableUpdate` as before.
