Eclair v0.10.0 introduces significant updates for the Lightning Network, including official support for dual-funding, an implementation of Bolt 12 offers, and a splicing prototype. While these features await finalized specifications and cross-compatibility testing, they offer advanced functionality for users familiar with handling backwards-incompatible changes. This release also includes on-chain fee improvements, enhanced configuration options, performance upgrades, and minor bug fixes. Users can verify signatures using gpg and the release signing key, and builds are deterministic, reproducible with specific environments like Ubuntu 22.04 and AdoptOpenJDK 11.0.22. The upgrade process is seamless, requiring no channel closures.
