ZeroContact 3.0.0 moves the app to the permanent Android identity io.massdex.zerocontact and a new product-specific signing certificate.
This is a breaking install identity:
- Install this APK manually beside version 2.
- Do not uninstall version 2 until chats, WhatsApp Business launch, QR/link sharing, and any local history you need are verified.
- Version 3 includes one-time and Settings-based guidance for copying selected legacy history entries safely.
- Future in-app updates continue only inside io.massdex.zerocontact with the version 3 signer.
- Historical v2.x releases remain intact and recoverable.
The APK is non-debuggable and was locally verified for package/version identity, exact size and SHA-256, signing certificate, updater trust, migration policy, lint, unit tests, and release assembly. No hosted GitHub Actions were used.
