Plugins: We now explicitly check at startup that our default Bitcoin backend (bitcoind) does relay transactions. (3889)
Plugins: We now explicitly check at startup the version of our default Bitcoin backend (bitcoind). (3889)

Changed

Build: we no longer require extra Python modules to build. (3994)
Build: SQLite3 is no longer a hard build requirement. C-Lightning can now be built to support only the PostgreSQL back-end. (3999)
gossipd: The gossipd is now a lot quieter, and will log only when a message changed our network topology. (3981)
Protocol: We now make MPP-aware routehints in invoices. (3913)
onchaind: We now scorch the earth on theft attempts, RBFing up our penalty transaction as blocks arrive without a penalty transaction getting confirmed. (3870)
Protocol: fundchannel now shuffles inputs and outputs, and no longer follows BIP69. (3769)
JSON-RPC: withdraw now randomizes input and output order, not BIP69. (3867)
JSON-RPC: txprepare reservations stay across restarts: use fundpsbt/reservepsbt/unreservepsbt (3867)
config: min-capacity-sat is now stricter about checking usable capacity of channels. (3969)
Protocol: Ignore (and log as "unusual") repeated WIRE_CHANNEL_REESTABLISH messages, to be compatible with buggy peer software that sometimes does this. (3964)
contrib: startup_regtest.sh startup_ln now takes a number of nodes to create as a parameter (3992)
JSON-RPC: invoice no longer accepts zero amounts (did you mean "any"?) (3974)
Protocol: channels now pruned after two weeks unless both peers refresh it (see lightning-rfc#767) (3959)
Protocol: bolt11 invoices always include CLTV fields (see lightning-rfc#785) (3959)
config: the default CLTV expiry is now 34 blocks, and final expiry 18 blocks as per new BOLT recommendations. (3959)
Plugins: Builtin plugins are now marked as important, and if they crash, will cause C-lightning to stop as well. (3890)
Protocol: Funding timeout is now based on the header count reported by the bitcoin backend instead of our current blockheight which might be lower. (3897)
JSON-RPC: delinvoice will now report specific error codes: 905 for failing to find the invoice, 906 for the invoice status not matching the parameter. (3853)

Deprecated

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

Plugins: bcli replacements should note that sendrawtransaction now has a second required Boolean argument, allowhighfees, which if true, means ignore any fee limits and just broadcast the transaction. (3870)
JSON-RPC: listsendpays will no longer add null if we don't know the amount_msat for a payment. (3883)
Plugins: getmanifest without any parameters; plugins should accept any parameters for future use. (3883)

Removed

Fixed

Plugins: pay presplit modifier now supports large payments without exhausting the available HTLCs. (3986)
Plugins: pay corrects a case where we put the sub-payment value instead of the total value in the total_msat field of a multi-part payment. (3914)
Plugins: pay is less aggressive with forgetting routehints. (3914)
Plugins: pay no longer ignores routehints if the payment exceeds 10,000 satoshi. This is particularly bad if the payee is only reachable via routehints in an invoice. (3908)
Plugins: pay limits the number of splits if the payee seems to have a low number of channels that can enter it, given the max-concurrent-htlcs limit. (3936)
Plugins: pay will now make reliable multi-part payments to nodes it doesn't have a node_announcement for. (4035)
JSON-RPC: significant speedups for plugins which create large JSON replies (e.g. listpays on large nodes). (3957)
doc: Many missing manual pages were completed (3938)
Build: Fixed compile error on macos (4019)
pyln: Fixed HTLCs hanging indefinitely if the hook function raises an exception. A safe fallback result is now returned instead. (4031)
Protocol: We now hang up if peer doesn't respond to init message after 60 seconds. (4039)
elementsd: PSBTs include correct witness_utxo struct for elements transactions (4033)
cli: fixed crash with listconfigs in -H mode (4012)
Plugins: bcli significant speedups for block synchronization (3985)

Build: On some operating systems the postgresql library would not get picked up. ./configure now uses pg_config to locate the headers. (3991)
libplugin: significant speedups for reading large JSON replies (e.g. calling listsendpays on large nodes, or listchannels / listnodes). (3957)

Plugin: new notifications invoice_payment, forward_event and channel_opened.
Protocol: --enable-experimental-features adds gossip query extensions aka https://github.com/lightningnetwork/lightning-rfc/pull/557
contrib: new bootstrap-node.sh to connect to random mainnet nodes.
JSON API: listfunds now returns also funding_output for channels
Plugin: plugins can now suggest lightning-cli default to -H for responses.
Lightningd: add support for signet networks using the --network=signet or --signet startup option

Changed

Build: now requires python3-mako to be installed, i.e. sudo apt-get install python3-mako
JSON API: close optional arguments have changed: it now defaults to unilateral close after 48 hours.
Plugin: if the config directory has a plugins subdirectory, those are loaded.
lightningd: check bitcoind version when setup topology and confirm the version not older than v0.15.0.
Protocol: space out reconnections on startup if we have more than 5 peers.
JSON API: listforwards includes the 'payment_hash' field.
Plugin: now plugins always run from the lightning-dir for easy local storage.

Deprecated

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

Plugin: using startup-relative paths for plugin and plugin-dir: they're now relative to lightning-dir.
JSON API: listforwards removed dummy (zero) fields for out_msat, fee_msat, in_channel and out_channel if unknown (i.e. deleted from db, or status is local-failed.

Removed

Fixed

Plugin: pay no longer crashes on timeout.
Plugin: disconnect notifier now called if remote side disconnects.
channeld: ignore, and simply try reconnecting if lnd sends "sync error".
Protocol: we now correctly ignore unknown odd messages.
wallet: We will now backfill blocks below our wallet start height on demand when we require them to verify gossip messages. This fixes an issue where we would not remove channels on spend that were opened below that start height because we weren't tracking the funding output.
Detect when we're still syncing with bitcoin network: don't send or receive HTLCs or allow fundchannel.
Rare onchaind error where we don't recover our own unilateral close with multiple same-preimage HTLCs fixed.

0.6.1 - 2018-09-11: "Principled Opposition To Segwit"

This release was named by ZmnSCPxj.

Added

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.

We will no longer allow withdrawing funds or funding channels if we do not have a fee estimate (eg. bitcoind not synced); use new feerate arg.

Deprecated

Removed

JSON API: listpeers results no long have alias and color fields; they're in listnodes (we used to internally merge the information).
