What’s new

v1.0.2+3 — Security & Stability Update (Feb 19, 2026)

SECURITY
• URLs from scanned QR codes no longer auto-open in browser.
Users must explicitly tap "Open" to launch any URL.
• Added URL scheme allowlisting (http, https, mailto, tel, sms).
Blocks dangerous schemes like javascript:, file:, data:.

PERFORMANCE
• Switched to IndexedStack — camera and tabs preserve state
across navigation. No more camera restarts on tab switch.
• Scan history capped at 500 entries to prevent storage bloat.
