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.
- JSON API: New command
check
checks the validity of a JSON API call without running it. - JSON API:
getinfo
now returnsnum_peers
num_pending_channels
,num_active_channels
andnum_inactive_channels
fields. - JSON API: use
\n\n
to terminate responses, for simplified parsing (pylightning now relies on this) - Plugins: Added plugins to
lightningd
, including option passthrough and JSON-RPC passthrough.
- JSON API:
pay
anddecodepay
accept and ignorelightning:
prefixes.
Note: You should always set allow-deprecated-apis=false
to test for
changes.
- JSON API: uppercase invoices now parsed correctly (broken in 0.6.2).
- JSON API: commands are once again read even if one hasn't responded yet (broken in 0.6.2).
- Protocol: allow lnd to send
update_fee
beforefunding_locked
. - pylightning: handle multiple simultanous RPC replies reliably.
0.6.2 - 2018-10-20: "The Consensus Loving Nasal Daemon"
This release named by practicalswift.
- JSON API:
listpeers
has new fieldscratch_txid
: the latest tx in channel. - JSON API:
listpeers
has new arrayhtlcs
: the current live payments. - JSON API:
listchannels
has two new fields:message_flags
andchannel_flags
. This replacesflags
. - JSON API:
invoice
now adds route hint to invoices for incoming capacity (RouteBoost), and warns if insufficient capacity. - JSON API:
listforwards
lists all forwarded payments, their associated channels, and fees. - JSON API:
getinfo
shows forwarding fees earnt asmsatoshi_fees_collected
. - Bitcoind: more parallelism in requests, for very slow nodes.
- Testing: fixed logging, cleaner interception of bitcoind, minor fixes.
- Protocol: we set and handle the new
htlc_maximum_msat
channel_update field.
- Protocol:
channel_update
sent to disable channel only if we reject an HTLC. - Protocol: we don't send redundant
node_announcement
on every new channel. - Config: config file can override
lightning-dir
(makes sense with--conf
). - Config:
--conf
option is now relative to current directory, notlightning-dir
. - lightning-cli:
help <cmd>
prints basic information even if no man page found. - JSON API:
getinfo
now reports global statistics about forwarded payments, including total fees earned and amounts routed.
Note: You should always set allow-deprecated-apis=false
to test for
changes.
- JSON RPC:
listchannels
'flags
field. This has been split into two fields, see Added. - JSON RPC:
global_features
andlocal_features
fields: useglobalfeatures
andlocalfeatures
as per BOLT #1.
- Startup: more coherent complaint if daemon already running.
- Lightningd: correctly save full HTLCs across restarts; fixup old databases.
- JSON RPC:
getinfo
now shows correct Tor port. - JSON RPC:
ping
now works even after one peer fails to respond. - JSON RPC:
getroute
fuzzpercent
andpay
maxfeepercent
can now be > 100. - JSON RPC:
riskfactor
inpay
andgetroute
no longer always treated as 1. - JSON-RPC:
listpeers
was always reporting 0 for all stats. - JSON RPC:
withdraw all
saysCannot afford transaction
if you have absolutely no funds, rather thanOutput 0 satoshis would be dust
. - Protocol: don't send gossip about closed channels.
- Protocol: fix occasional deadlock when both peers flood with gossip.
- Protocol: fix occasional long delay on sending
reply_short_channel_ids_end
. - Protocol: re-send
node_announcement
when address/alias/color etc change. - Protocol: multiple HTLCs with the same payment_hash are handled correctly.
- Options: 'autotor' defaults to port 9051 if not specified.
0.6.1 - 2018-09-11: "Principled Opposition To Segwit"
This release named by ZmnSCPxj.
- 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.
- Protocol:
option_data_loss_protect
now supported to protect peers against being out-of-date. - JSON API: Added description to invoices and payments (#1740).
- JSON API:
getinfo
has new fieldsalias
andcolor
. - JSON API:
listpeers
has new fieldsglobal_features
andlocal_features
. - JSON API:
listnodes
has new fieldglobal_features
. - JSON API:
ping
command to send a ping to a connected peer. - JSON API:
feerates
command to retrieve current fee estimates. - JSON API:
withdraw
andfundchannel
can be given manual feerate. - Config:
--conf
option to set config file. - Documentation: Added CHANGELOG.md
- pylightning: RpcError now has
method
andpayload
fields. - Sending lightningd a SIGHUP will make it reopen its
log-file
, if any.
- Protocol: Fee estimates are now smoothed over time, to avoid sudden jumps.
- Config: You can only announce one address if each type (IPv4, IPv6, TORv2, TORv3).
- 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 ofgossipd
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
- 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.
- JSON API:
listpeers
results no long havealias
andcolor
fields; they're inlistnodes
(we used to internally merge the information). - JSON API:
listpeers
will never havestate
field (it accidentally used to exist and set toGOSSIPING
before we opened a channel).connected
will indicate if we're connected, and thechannels
array indicates individual channel states (if any). - Config:
default-fee-rate
is no longer available; use explicitfeerate
option if necessary. - Removed all Deprecated options from 0.6.
- Protocol:
node_announcement
multiple addresses are correctly ordered and uniquified. - Protocol: if we can't estimate feerate, be almost infinitely tolerant of other side setting fees to avoid unilateral close.
- 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. - JSON API:
listnodes
: now correctly printsaddresses
if more than one is advertised. - Config:
bind-addr
of a publicly accessible network address was announced. - When we reconnect and have to retransmit failing HTLCs, the errors weren't encrypted by us.
lightningd_config
man page is now installed bymake 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_update
s that are nested in an onion reply to be compatible with eclair and lnd (#1730). - Failing tests no longer delete the test directory, to allow easier debugging (Issue: #1599)
