# Eclair v0.6.2 This releases fixes a known vulnerability, makes several performance improvements, includes a few bug fixes and many new features. It is fully compatible with 0.6.1 (and all previous versions of eclair). This release requires a few actions from node operators when upgrading: make sure you read the release notes carefully! The release notes can be found [here](https://github.com/ACINQ/eclair/blob/master/docs/release-notes/eclair-v0.6.2.md). ## 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-0.6.2-6817d6f-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.
