Electrum users should upgrade: this $BTC wallet released version 4.8.4 on November 9, fixing a Lightning Network vulnerability—a maliciously crafted onion message could cause the wallet to disconnect from channel peers. Freezes and crashes on desktop and Android were also addressed. This is the fourth security update since August.

The vulnerability itself isn’t critical, but when a channel disconnects for no apparent reason, most people’s first thought is a network issue—not to click “Upgrade.”
