    November 10, 2020

  • v0.4.2 Changes

    October 19, 2020

    🚀 This release includes many exciting new features, API changes as well as several bug fixes and improvements.
    Its is fully compatible with 0.4.1 (and all previous versions of eclair).

    Major changes

    🔌 Plugins

    🔌 Third-party plugins are now able to add new feature bits to eclair and handle unknown custom messages.
    🔌 This lets plugin developers offer services to their customers that are not available in the Lightning specification (e.g. swap-in/swap-out), while staying fully compatible with the network.

    👀 See #1528 for more details.

    Anchor Outputs

    🚀 This release adds experimental support for anchor outputs channels.
    The main benefit of this type of channels is that it is possible to bump the on-chain fees of commitment transactions and htlc transactions once they are in the mempool to speed up their confirmation.

    Eclair is fully compatible with the anchor output specification, but automatic fee bumping has not been implemented yet, hence we do not recommend activating the feature.
    🚀 Some attacks that are specific to anchor outputs have also been discovered recently and haven't been fully addressed yet, but will be fixed in future releases.

    Keysend

    🚀 This release adds support for spontaneous payments using keysend.
    It is fully compatible with lnd and c-lightning and makes it easy for public LN nodes to receive donations.

    API changes

    🚀 This release contains many new APIs and improvements to existing ones:

    • ➕ Add signmessage/verifymessage APIs: this allows signing arbitrary messages with the node's key and is compatible with lnd and c-lightning
    • We publish new channel events to the websocket (channel-opened, channel-state-changed and channel-closed)
    • The sendtoroute API now lets you choose the channels that must be used, making it easy to rebalance your local channels

    📚 Head over to our API documentation for more details.

    🛠 Miscellaneous improvements and bug fixes

    • 🔨 Many actors have been refactored to use Akka Typed instead of classic actors.
      👍 This leads to a cleaner design, better types and more help from the compiler to detect unhandled messages.
    • 👍 We added support for Bitcoin Core 0.20.1.
    • 👀 We added support for non-default Bitcoin Core wallets (see #1540 for details)
    • 🔧 We fixed the override-features configuration parameter, which wasn't overriding features everywhere. This parameter can be very useful for example to sync only from specific nodes, or advertize wumbo support only to nodes that you trust.

    👌 Verifying signatures

    🚀 You will need gpg and our release signing key 7A73FE77DE2C4027. Note that you can get it:

    To import our signing key:

    $ gpg --import drouinf.asc

    🚀 To verify the release file checksums and signatures:

    $ gpg -d SHA256SUMS.asc \> SHA256SUMS.stripped $ sha256sum -c SHA256SUMS.stripped

    🏗 Building

    🏗 Eclair builds are deterministic. To reproduce our builds, please use the following environment (*):

    • Ubuntu 19.10
    • AdoptOpenJDK 11.0.6
    • Maven 3.6.3

    📦 Use the following command to generate the eclair-node package:

    mvn clean install -DskipTests

    That should generate eclair-node/target/eclair-node-0.4.2-XXXXXXX-bin.zip with sha256 checksums that matches the one we provide and sign in SHA256SUMS.asc

    🏗 (*) You may be able to build the exact same artefacts with other operating systems or versions of JDK 11, we have not tried everything.

    ⬆️ Upgrading

    🚀 This release is fully compatible with Eclair v0.4.1. You don't need to close your channels, just stop eclair, upgrade and restart.

    🔄 Changelog

  • v0.4.2-android

    October 14, 2020

  • v0.4.1 Changes

    July 15, 2020

    🚀 This release includes many exciting new features, API changes as well as several bug fixes and improvements.
    Its is fully compatible with 0.4 (and all previous versions of eclair).

    Major changes

    Static Remote Key

    This release adds support for option_static_remotekey.
    ⚡️ This removes the key rotation at each update of the commitment, and allows simpler funds recovery in case of backup loss: channel outputs will directly pay to one of your bitcoin wallet addresses.

    0️⃣ This option is disabled by default, and will only be available for new channels when both peers activate the feature.
    To enable it, add the following lines to your eclair.conf:

    eclair.features {
    option_static_remotekey = optional
}

    You can verify that this is activated with the getinfo API, which now returns the list of features:

    "features": { "activated": [{ "name": "basic\_mpp", "support": "optional" }, { "name": "initial\_routing\_sync", "support": "optional" }, { "name": "option\_data\_loss\_protect", "support": "optional" }, { "name": "gossip\_queries\_ex", "support": "optional" }, { "name": "payment\_secret", "support": "optional" }, { "name": "var\_onion\_optin", "support": "optional" }, { "name": "gossip\_queries", "support": "optional" }], "unknown": [] }

    👌 Improvements to path-finding and MPP

    We've made several improvements to the path-finding algorithm. It now takes into account your channel's current balance more accurately when selecting a route.

    🚀 The MPP split algorithm has been rewritten from the ground up, inspired by flow algorithms (see #1427 for details). MPP is now enabled by default (it was introduced in eclair v0.3.3 but was opt-in) for all eclair nodes and will soon be available on eclair-mobile (note that Phoenix has had MPP support since its first release).

    MPP synergizes well with trampoline: trampoline nodes aggregate incoming MPP and re-split them more efficiently on outgoing channels.

    👍 PostgreSQL beta support

    👍 Thanks to @rorp, eclair now supports PostgreSQL as a database backend!

    0️⃣ By default eclair still uses SQLite, but you can follow the instructions here to use PostgreSQL instead.

    We're looking for feedback on how well this is working for you, so don't hesitate to try it out and let us know!

    Human-readable features

    Say goodbye to hex-encoded features: we've changed the format to be human-readable.

    🔧 Here is how they are configured by default:

    eclair.features {
  initial_routing_sync = optional
  option_data_loss_protect = optional
  gossip_queries = optional
  gossip_queries_ex = optional
  var_onion_optin = optional
  payment_secret = optional
  basic_mpp = optional
}

    Note that if you want to disable features, there is a trick. You need to first set the features to null and then provide your set of chosen features, for example (in your eclair.conf):

    eclair.features : null
eclair.features {
  option_data_loss_protect = optional
  var_onion_optin = optional
  payment_secret = optional
  basic_mpp = optional
  option_static_remotekey = optional
}

    You can verify what features have been set with the getinfo API:

    eclair-cli getinfo { "version": "0.4.1-SNAPSHOT-xxxxxxx", "nodeId": "...", "alias": "...", "color": "...", "features": { "activated": [{ "name": "basic\_mpp", "support": "optional" }, { "name": "initial\_routing\_sync", "support": "optional" }, { "name": "option\_data\_loss\_protect", "support": "optional" }, { "name": "gossip\_queries\_ex", "support": "optional" }, { "name": "payment\_secret", "support": "optional" }, { "name": "var\_onion\_optin", "support": "optional" }, { "name": "gossip\_queries", "support": "optional" }], "unknown": [] }, "chainHash": "...", "network": "...", "blockHeight": 1, "publicAddresses": [], "instanceId": "..."}

    Feerate mismatch

    When you disagree with your peer about on-chain fee rates, your funds may be at risk if your peer is malicious.
    For this reason, eclair has always been closing channels on your behalf before the situation gets too dangerous.

    🔧 Your tolerance to fee rate mismatch was previously configured via eclair.on-chain-fees.max-feerate-mismatch.
    🔧 You can now independently configure your tolerance to either lower or higher fee rates:

    eclair.on-chain-fees.feerate-tolerance {
  ratio-low = 0.5 // will allow remote fee rates as low as half our local feerate
  ratio-high = 10.0 // will allow remote fee rates as high as 10 times our local feerate
}

    0️⃣ It's less dangerous if your peer overestimates the fees than if she underestimates it, hence the different default values.

    We've also made changes to reduce the number of unnecessary close, by only closing channels when there are funds at risk in pending HTLCs. If your channel doesn't have pending HTLCs, eclair will safely ignore the remote fee rate and won't close the channel.

    API changes

    🚀 This release is packed with new APIs and improvements to existing ones:

    • ⚡️ batch channel updates (updaterelayfee, close, forceclose)
    • nodes to lookup node announcements
    • 👍 better channelstats
    • onchainbalance, sendonchain and onchaintransactions to interact with layer-1
    • more data returned in most API responses

    📚 Head over to our API documentation for more details.

    🛠 Miscellaneous improvements and bug fixes

    • 👍 More metrics for an even better monitoring experience with Kamon.
    • Various improvements to connection handling and reconnection logic.
    • ⚡️ Updates to security parameters default values.
    • Various improvements on fee estimation.
    • 👍 Better errors for trampoline payments.
    • 🌲 Logging improvements.

    👌 Verifying signatures

    🚀 You will need gpg and our release signing key 7A73FE77DE2C4027. Note that you can get it:

    To import our signing key:

    $ gpg --import drouinf.asc

    🚀 To verify the release file checksums and signatures:

    ⬆️ Upgrading

    🚀 This release is fully compatible with Eclair v0.4. You don't need to close your channels, just stop eclair, upgrade and restart.

    🔄 Changelog

  • v0.4 Changes

    July 15, 2020

    🚀 This release includes major upgrades to our core libraries (Scala and Akka), as well as several bug fixes and improvements.
    Its is fully compatible with 0.3.4 (and all previous versions of eclair).

    Major changes

    Scala 2.13, Akka 2.6

    ⚡️ Update from Scala 2.11 and Akka 2.4 to Scala 2.13 and Akka 2.6.

    Scala 2.13 brings a lot of improvements, among which:

    • 👍 better performance
    • tons of improvements for standard collections
    • faster compile times
    • 👍 better support for deterministic builds

    Akka 2.6 contains a couple years of steady improvements over Akka 2.4:

    • 👍 better performance
    • 👍 better APIs and the introduction of typed actors
    • production-ready akka-cluster

    ⚡️ Eclair will incrementally take advantage of the new features these updates have to offer.

    Bitcoin 0.19.1

    ➕ Add support for Bitcoin Core 0.19.1.

    The most notable change impacting eclair is that fundrawtransaction does not fail when providing a too low feerate, but instead bitcoin will fail when broadcasting the transaction with sendrawtransaction. This is correctly handled by eclair v0.4.

    🗄 GUI deprecation

    🚀 eclair-node-gui is being deprecated and will is not published with this release. Source code will still remain available for some time, and building the GUI is very easy (check BUILD.md for more details, but basically mvn install -DskipTests is enough to build eclair-node and eclair-node-gui).

    🏁 We strongly encourage people to use the API instead, see here for more information (it works on Windows too). We also added instructions on how to setup a monitoring endpoint, where you can create your own graphs and alerts.

    ✅ Our GUI was built for demonstration and testing purposes, typically with a few nodes on single machine and in regtest mode. Using it as a Lightning wallet or to run routing nodes on mainnet is a very bad fit:

    • if you're looking for a Lightning wallet, consider using Phoenix or Eclair Mobile instead.
    • if you want to run a routing node, then it should be running on a machine that is reliable, secure, maintained, reachable from the internet and online most of the time, i.e probably not your desktop PC.
    • having a "bitcoin-like" GUI is misleading: if your Bitcoin node is offline it has a minimal impact on the Bitcoin network and you can still "receive" funds. When you start it again it catches up on the blocks and transactions that it has missed, so having a Bitcoin wallet or node that is often offline is fine. But when your Lightning node is offline it cannot send, receive or relay transactions. Your channels will be tagged as disabled and other nodes will have to route around you and will likely avoid you in the future because of your unreliability.

    🛠 Miscellaneous improvements and bug fixes

    • 👍 More metrics for an even better monitoring experience with Kamon.
    • 👌 Improvements to our p2p handling of incoming and outgoing connections.
    • 🛠 Fixed some race conditions in tests that were leading to random build failures.
    • ➕ Added more tests around mempool introspection to extract preimages early.
    • 🛠 UTXOs weren't always correctly unlocked in the Bitcoin Core wallet in case funding failed (fixed in #1404)

    👌 Verifying signatures

    🚀 You will need gpg and our release signing key 7A73FE77DE2C4027. Note that you can get it:

    To import our signing key:

    $ gpg --import drouinf.asc
