What is C-Lightning? And how to use it…
- Payments can now be retried without affecting the status of prior attempts.
- The route selection will now use the log-propability-based channel selection to increase success rate and reduce time to completion.
- Close now reports the feeranges each side enforced, which allows users to determine which side caused a high or low feerate.
- Removal of old HTLC information and vacuuming shrinks large lightningd.sqlite3 by a factor of 2–3.
- setchannelfee now has a grace period during which both old and new fee policies are considered. This prevents a fee update from making the channel unusable until the update propagated.
- We now perform quick-close if the peer supports it.
- We send regular pings to detect dead connections (particularly for Tor).
- Errors returning a channel_update no longer return an outdated one.
- Anchor output mutual close allow a fee higher than the final commitment transaction.
- Plugins now are notified about an upcoming shutdown, allowing them to store data and clean up before exiting.
- The datastore API (datastore, deldatastore, and listdatastore) exposes a simple key-value store, allowing plugin authors to store data in the c-lightning database.
- ping now only works if we have a channel with the peer.
- Relaxed the sqlite3 version match requirements to be at least a minimum version and a major version match
