Highlights for Users

• We now finally support multiple live channels to the same peer!
• If we detect rust support, we'll build the cln-grpc plugin for full native GRPC support.
• We advertize an external IP address if it's reported by two or more peers (disable-ip-discovery or always-use-proxy disables).
• You can specify two databases with --wallet, and we'll write to both at once (sqlite3 only).
• pay supports BOLT 11 payment metadata: we'll send it if it's in the invoice.
• New setchannel command (deprecates setchannelfee) allows setting max and min HTLC amounts. Try lightning-cli setchannel all 0 for #zerobasefee.
• pay can be forced to exclude channels or nodes with the exclude
  S- ignificant speedup in start times for old nodes with many historical HTLCs.

Highlights for the Network

• We send the remote node's IP address in the init message, so they can tell what it is. (lightning/bolts#917)
• We are more aggressive in sending our own gossip to peers, to help propagation.
• Default port is set by network, so regtest and testnet defaults are different. (lightning/bolts#968)
• We never generate legacy onions, it's always TLV. We still forward legacy onions for now.
• We flush sockets before closing, so errors are more likely to reach the peer.
• Experimental support for announcing DNS addresses in node_announcement (lightning/bolts#911)

Highlights for Developers

• pay has a maxfee parameter, which sets a simple LND-style upper fee (vs using maxfeepercent and exemptfee)
• You can create invoices with only a description hash, using deschashonly. We still store the full description, so use restraint!
• pay has deprecated paying solely by description hash: you should provide the full description, too.
• delinvoice has a new desconly parameter to simply trim the descriptions, but leave the rest intact.
• We have a rust crate cln-rpc to easily interact with our JSON-RPC.
  msggen tool allows easy generation of language bindings for our JSON RPC interface.
