* Update kamon and kanela-agent

Previous version was not compatible with JDK21, see https://github.com/kamon-io/kanela/issues/150.

* Add and configure maven wrapper to use maven 3.9.9

This will make it easier to control which version of maven is used to build eclair, which in turns makes deterministic builds easier, as well as using recent compiler options (to target newer JDKs for example).
For example, even recent versions of Github runner images use an old version of maven and there is no easy way to upgrade.

* Update Dockerfile

We now use multiarch (amd64/arm64) base images.

* Run CI tests with JDK21

* Update doc to recommend Adoptium OpenJDK21

* Target Java 21

Eclair now targets Java 21 and will require a compatible Java Runtime Environment.
It will no longer work on JRE 11 and JRE 17.

Raw Blame History

Eclair vnext

Major changes

Peer storage

With this release, eclair supports the option_provide_storage feature introduced in https://github.com/lightning/bolts/pull/1110. When option_provide_storage is enabled, eclair will store a small encrypted backup for peers that request it. This backup is limited to 65kB and node operators should customize the eclair.peer-storage configuration section to match their desired SLAs. This is mostly intended for LSPs that serve mobile wallets to allow users to restore their channels when they switch phones.

Eclair requires a Java 21 runtime

Eclair now targets Java 21 and requires a compatible Java Runtime Environment. It will no longer work on JRE 11 or JRE 17. There are many organisations that package Java runtimes and development kits, for example OpenJDK 21.

API changes

Miscellaneous improvements and bug fixes

Verifying signatures

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

from our website: https://acinq.co/pgp/drouinf.asc
from github user @sstone, a committer on eclair: https://api.github.com/users/sstone/gpg_keys

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 24.04.1
Adoptium OpenJDK 21.0.4
Maven 3.9.2

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

./mvnw clean install -DskipTests

That should generate eclair-node/target/eclair-node-<version>-XXXXXXX-bin.zip with sha256 checksums that match 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 previous eclair versions. You don't need to close your channels, just stop eclair, upgrade and restart.
