Electrum version 4.8.2 fixes a Lightning backup defect by retaining payment-key information needed to reclaim funds from an anchor channel (a Lightning channel type) closed by the peer. The issue affects only wallets with non-deterministic Lightning keys and backups involving anchor channels. Such keys cannot be recreated from a wallet seed, so affected backups may lack the private key required to sweep the output and claim coins on the Bitcoin blockchain. The update, dated Sept. 11 and still the latest release listed on Electrum’s official website as of Oct. 1, repairs future exports but does not restore key material already missing from older files. Electrum therefore requires affected users to make fresh individual or full-wallet exports using the original wallet data, with startup warnings displayed by affected wallets.
