All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

Unreleased

Added

• Documentation: Added CHANGELOG.md
• JSON API: getinfo has new fields alias and color.
• JSON API: listpeers has new fields global_features and local_features.
• JSON API: listnodes has new field global_features.
• JSON API: ping command to send a ping to a connected peer.
• Protocol: gossipd now deliberately delays spamming with channel_update.
• Protocol: liveness ping when we commit changes but peer is idle: speeds up failures and reduces forced closures.
• Config: --conf option to set config file.
• JSON API: Added description to invoices and payments (#1740).
• pylightning: RpcError now has method and payload fields.
• Sending lightningd a SIGHUP will make it reopen its log-file, if any.
• Protocol: option_data_loss_protect now supported to protect peers against being out-of-date.

Changed

• Config: You can only announce one address if each type (IPv4, IPv6, TORv2, TORv3).
• Protocol: Fee estimates are now smoothed over time, to avoid sudden jumps.
• lightning-cli: the help command for a specific command now runs the man command.
• HSM: The HSM daemon now maintains the per-peer secrets, rather than handing them out. It's still lax in what it signs though.
• connectd: A new daemon lightning_connectd handles connecting to/from peers, instead of gossipd doing that itself. lightning_openingd now handles peers immediately, even if they never actually open a channel.
• Test: python-xdist is now a dependency for tests.
• Logging: JSON connections no longer spam debug logs.
• Routing: We no longer consider channels that are not usable either because of their capacity or their htlc_minimum_msat parameter (#1777)
• We now try to connect to all known addresses for a peer, not just the one given or the first one announced.
• Crash logs are now placed one-per file like crash.log.20180822233752

Deprecated

Note: You should always set allow-deprecated-apis=false to test for changes.

Removed

• JSON API: listpeers results no long have alias and color fields; they're in listnodes (we used to internally merge the information).
• JSON API: listpeers will never have state field (it accidentally used to exist and set to GOSSIPING before we opened a channel). connected will indicate if we're connected, and the channels array indicates individual channel states (if any).
• Options: default-fee-rate is no longer available.
• Removed all Deprecated options from 0.6.

Fixed

• Options: bind-addr of a publicly accessible network address was announced.
• Protocol: node_announcement multiple addresses are correctly ordered and uniquified.
• JSON API: listnodes: now displays node aliases and colors even if they don't advertise a network address
• JSON API: fundchannel all: now restricts to 2^24-1 satoshis rather than failing.
• When we reconnect and have to retransmit failing HTLCs, the errors weren't encrypted by us.
• lightningd_config man page is now installed by make install.
• Fixed crash when shutting down during opening a channel (#1737)
• Don't lose track of our own output when applying penalty transaction (#1738)
• Protocol: channel_update inside error messages now refers to correct channel.
• Stripping type prefix from channel_updates that are nested in an onion reply to be compatible with eclair and lnd (#1730).
• JSON API: listnodes: now correctly prints addresses if more than one is advertised.
• Failing tests no longer delete the test directory, to allow easier debugging (Issue: #1599)
• Protocol: if we can't estimate feerate, be almost infinitely tolerant of other side setting fees to avoid unilateral close.

Security
