- Multiaddresses that can't be parsed during the discovery process are now silently ignored instead of causing the entire list of discovered nodes to be discarded. ([#705](https://github.com/smol-dot/smoldot/pull/705))

### Fixed

- Fix wrong trie root hash calculation with `state_version = 1`. ([#711](https://github.com/smol-dot/smoldot/pull/711))
