+### Explicit Channel Negotiation
+
+[A new protocol extension has been added known as explicit channel negotiation]
+(https://github.com/lightningnetwork/lnd/pull/5669). This allows a channel
+initiator to signal their desired channel type to use with the remote peer. If
+the remote peer supports said channel type and agrees, the previous implicit
+negotiation based on the shared set of feature bits is bypassed, and the
+proposed channel type is used.
