Electrum Releases Version 4.8.2, Fixing Lightning Wallet Backup Issues

Electrum has released version 4.8.2, which includes several security fixes and enhances the security of the Bitcoin wallet codebase. This version addresses a critical backup issue affecting some Lightning wallets that use non-deterministic keys and anchored channels. The affected wallets may lack the keys necessary to transfer funds on-chain after a remote force close request, both for channel backups and full wallet backups. Users with affected wallets will receive a warning upon launching Electrum and should export a new backup, as the old backup will not correctly restore funds in this scenario. This version also strengthens Lightning HTLC validation by rejecting previously acceptable format errors in xpub/xprv keys, expands the scope of codebase security enhancements, and prevents Android QR code scanners from reading screenshots. This is the third security-focused release from Electrum since July, following versions 4.8.0 and 4.8.1.
