This update prompt is not an official act of Electrum, but a phishing attack by an attacker that exploits a message flaw on the Electrum client and the ElectrumX server, which requires the attacker to deploy the malicious ElectrumX server in advance, and the malicious server is localized by the user's Electrum client (because the Electrum client is a light wallet and the user needs the ElectrumX server to broadcast the transaction). At the time of the madness, malicious ElectrumX servers accounted for as many as 71% of the total, and according to incomplete statistics, hundreds of bitcoins have been stolen in this phishing attack over the past year or so.

The new version of the wallet will also include undersea switching, which allows BTC to pass from the Bitcoin blockchain to the payment channel network LN. For this novelty, Electrum is based on Boltz technology. Electrum will charge a commission for this service.
