Malformed onion messages from any source could cause Electrum to disconnect from its channel peers.

The release notes indicate that the version is dated November 6; Electrum will discard incoming onion messages until practical use cases are implemented. The update also fixes an issue where some seed phrases from versions prior to 2.0 could not be restored.
