This release contains a lot of refactoring and an initial implementation of taproot channels.
The specification for taproot channels is still ongoing (lightning/bolts#995) so this cannot be used yet, but it is ready for cross-compatibility tests with other implementations.
This release also contains improvements to splicing based on recent specification updates, and better Bolt 12 support.
Note that the splicing specification is still pending, so it cannot be used with other implementations yet.
This is the last release of eclair where channels that don't use anchor outputs will be supported.
If you have channels that don't use anchor outputs, you should close them (see below for more details).
As usual, this release contains various performance improvements, more configuration options and bug fixes.
In particular, the amount of data stored for each channel has been optimized (especially during force-close), which reduces the size of the channels DB.
Also, the performance of the on-chain watcher during mass force-close has been drastically improved.

Verifying signatures
You will need gpg and our release signing key E04E48E72C205463. Note that you can get it:
- from our website: https://acinq.co/pgp/drouinf2.asc
- from github user @sstone, a committer on eclair: https://api.github.com/users/sstone/gpg_keys
To import our signing key:
$ gpg --import drouinf2.ascTo verify the release file checksums and signatures:
$ gpg -d SHA256SUMS.asc > SHA256SUMS.stripped
$ sha256sum -c SHA256SUMS.strippedBuilding
Eclair builds are deterministic. To reproduce our builds, please use the following environment (*):
- Ubuntu 24.04.1
- Adoptium OpenJDK 21.0.6
Then use the following command to generate the eclair-node packages:
./mvnw clean install -DskipTestsThat 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 21, 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.
