**[Electrum Releases Version 4.8.2: Fixes Critical Lightning Wallet Backup Issue and Enhances Security]** According to a report by Jinse Finance, Electrum has released version 4.8.2, introducing multiple security fixes and strengthening the security of the Bitcoin wallet codebase. These fixes are based on reports from researchers including Bitcoin Red Team, Calle, l0rinc, haoxucu, and m0wer. This version addresses a critical backup issue affecting certain Lightning wallets that use non-deterministic keys and anchor channels. Previously, the channel backups and full wallet backups of affected wallets might have lacked the keys required to transfer funds on-chain after requesting a remote force-close. Affected users will receive a warning when launching Electrum and should export a new backup, as the old backup cannot correctly restore funds in this scenario. The update also enhances Lightning HTLC validation, rejects previously acceptable but malformed xpub/xprv keys, expands the scope of codebase security hardening, and prevents the Android QR code scanner from reading screenshots. This marks Electrum's third security-focused release since July, following versions 4.8.0 and 4.8.1.
