Original release notes

Stay Frosty.

Highlights

On-device backup check: a short multiple-choice quiz on the device tests that you've written down the backup correctly. (#453, #460)
Verify Address dialog: redesigned with a blurred tap-to-reveal address and caution guidance - clearer best practices for receive-address verification. (#442)
Receive-address detail on incoming transactions: see which address each payment landed on, with its derivation index. (#470)
Backup reminders surface when they matter: removed the auto-popup after wallet creation; reminder dialog appears when tapping Receive on a wallet with incomplete backups, and the "unfinished backups" banner turns red once funds land. (#468)
Fixed: balance stuck at 0 after delete-and-restore until the app was fully restarted. Likely also the cause of several intermittent UI-staleness reports. (#481)
