Good news among the bad news! If the recent #0day attacks against Linux kernel+servers were launched against #chatmail relays, privacy of chatting with #deltachat is preserved. Why? Because we already assume the server could be actively hostile, and still not read or see any avatar, names or messages. Since the March 2.48 zero-metadata releases relays/servers do not see cryptographic identities, and get no chance to launch "machine-in-the-middle" (MITM) attacks. https://delta.chat/en/2026-03-31-zero
