Electrum released version 4.8.4 on November 6 with a security fix for Lightning. Certain malformed messages could disconnect the wallet from its channel peers, according to its official release notes.

If you use this wallet for your $BTC , the fact that the app opens and shows your balance doesn’t tell the whole story: some fixes address problems you won’t see on the main screen.

Electrum advises downloading only from electrum.org and verifying the file’s signatures. I’d start by checking which version I have and reading what’s changed before opening any “update” link I receive.

How do you find out when your wallet has an important update?
