# Eclair vnext ## Major changes ### API changes ### Miscellaneous improvements and bug fixes #### Delay enforcement of new channel fees When updating the relay fees for a channel, eclair can now continue accepting to relay payments using the old fee even if they would be rejected with the new fee. By default, eclair will still accept the old fee for 10 minutes, you can change it by setting `eclair.relay.fees.enforcement-delay` to a different value. If you want a specific fee update to ignore this delay, you can update the fee twice to make eclair forget about the previous fee. ## 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: ```sh $ gpg --import drouinf.asc ``` To verify the release file checksums and signatures: ```sh $ 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 20.04 - AdoptOpenJDK 11.0.6 - Maven 3.8.1 Use the following command to generate the eclair-node package: ```sh mvn clean install -DskipTests ``` That should generate `eclair-node/target/eclair-node--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. ## Changelog
