What's new

v2.7.7Sep 16, 2026

・Fixed: turning the VPN firewall off and on quickly could leave it off.
・Fixed: with Block All on root or Shizuku, apps could stay unblocked while the firewall showed as on. A start that cannot read the app list now reports the firewall as down.
・Fixed: package actions could wrongly say root or Shizuku was missing.
・Fixed: VPN mode drained the battery. The tunnel kept CPU cores busy, and root checks ran too often.
・Fixed: for work and clone profile apps, VPN rules, Force stop, Reinstall and new-app notifications could act on your personal profile.
