PIN unlock is rebuilt on device hardware. The vault key is sealed by the Android
Keystore instead of by the PIN, and every attempt spends a hardware-limited gate,
so a copied copy of app storage can no longer be used to guess your PIN offline.
Autofill no longer generates or copies a two-factor code before you choose an entry.
Site icons now ask before they are switched on, and say what enabling them shares.
Fixes
Autofill no longer trusts a claimed website unless the app making the request is a
verified browser.
The encrypted sync spool is excluded from cloud backup and device-to-device transfer.
Biometric escrow keys must now report a hardware-backed security level.
Bouncy Castle is upgraded to 1.84.
Debug builds no longer log two-factor codes or entry titles.
