What is new in LanGuard 1.1.2

- Quitting, updating or relaunching LanGuard keeps connection protection — your connections survive; the guardian keeps it safe meanwhile.
- Fixed: after a relaunch, addresses LanGuard used before were wrongly treated as taken.
- After upgrading: Settings › Protection › **Update helper…** (one admin password).
