Eclair v0.13.1 introduces significant database changes to support the transition away from pre-anchor channels. This release requires users to first upgrade to v0.13.0 to ensure channel data is migrated to the latest internal encoding. Channels without anchor outputs will no longer be supported after this release, and users are advised to close such channels. The update also includes a dependency upgrade to Bitcoin Core v29.x, with v29.2 recommended. Users can verify the release using GPG with the signing key available from ACINQ's website or GitHub. The build process is deterministic, and the release is compatible with previous versions, allowing for a seamless upgrade without closing channels.
