By default we sync with every peer when reconnecting, which can be a lot. We now only sync on reconnection with our top peers (by capacity of our shared channels).

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
Gossip sync limits
On reconnection, eclair now only synchronizes its routing table with a small number of top peers instead of synchronizing with every peer.
If you already use sync-whitelist, the default behavior has been modified and you must set router.sync.peer-limit = 0 to keep preventing any synchronization with other nodes.
You must also use router.sync.whitelist instead of sync-whitelist.
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
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.
