C-lightning: A specification compliant Lightning Network implementation in C

C-lightning is a lighweight, highly customizable and standard compliant implementation of the Lightning Network protocol.
C-lightning only works on Linux and Mac OS, and requires a locally (or remotely) running groestlcoind (version 2.16.0 or above) that is fully caught up with the network you're testing on.

Changelog 0.9.2
• The sending of multi-part payments has seen a lot of work, covering more corner cases and generally becoming much more robust.
• New official plugins create commands multiwithdraw and multifundchannel to easily produce a single transaction which does more than one thing; these use the PSBT plumbing created for v0.9.0.
• We produce far less log spam when log-level is set to debug, so if you've avoided setting that before, I recommend trying now.
• Startup checks that groestlcoind is the correct version, and relays transactions
• Builtin plugins are now nominated as important, and you can nominate others as important too. The daemon will stop if these fail.
• You can now build a postgres-only installation, without sqlite3.
• Our invoices now supply more than one routehint if we think you'll need to use multi-part-payments.
• We prune channels which are not updated in both directions every 2 weeks.
• Our default CTLV expiry has increased to 34 blocks, or 18 if we're the final node, as per updated specification recommendations (lightningnetwork/lightning-rfc#785)
• PSBT APIs fleshed out with utxopsbt and locktime arguments.
• Plugins can easily mark commands and options deprecated.
• The new channel_state_changed notification lets plugins easily track channel behavior.
• We now keep track of channel closure rationales. Wonder "why did my channel close" no more. All channel state changes are now listed in listpeers's state_changes.
• New CLI/RPC notifications: Tired of waiting for close to finish without getting any updates? With notifications, the close command will publish notifications (think CLI status updates) for slow closes. Must have allow-deprecated-apis set to false for these to work.
• New optional argument commitment_feerate on the multifundchannel command. This is useful for setting one feerate for the funding transaction and another for the channel commitment transactions.
• Two new commands added to hsmtool:
- generatehsm allows you to create an HSM hsm_secret from a BIP39 pass phrase. (Note that due to c-lightning's current seed derivation process, wallet addresses aren't standard 'BIP39 to BIP32' compliant. Which is a fancy way of saying your pass phrase isn't portable to other, non-clightning wallets.)
- dumponchaindescriptors will output the xpub for the HD wallet master key. This will let you track swept c-lightning wallet funds -- anchor outputs and unswept channel outputs won't be visible until swept.
• The starting feerate for mutual closes has been reduced to 'slow', to avoid overpayment.
• In-memory log buffer now is 10MB, down from 100MB.
• We no longer support receiving full gossip from ancient LND nodes
• Fixed re-transmission order of multiple new HTLCS. This was causing channel closures with LND.
• Plugin hook call ordering. Hooks can now specify that they must be called 'before' or 'after' other plugins.
• pyln-client will handle and send RPC command notifications.
• pyln-proto now includes a pure python implementation of the sphinx onion creation and processing.
• PostgresSQL key-value DSNs now supported.
• Plugin hook htlc_accepted can now return a custom failure_onion.

• Creating channels.
• Closing channels.
• Completely managing all channel states (including the exceptional ones!).
• Performing path finding within the network, passively forwarding incoming payments.
• Sending outgoing onion-encrypted payments through the network.
• Automatic channel management (autopilot).
