COLDCARD Mk4 Firmware 5.2.0 release 🍄⏫
## **TL;DR**: First #bitcoin Singing-Device to store MULTIPLE seeds 🎉. Switch between them effortlessly. Ideal for custodians (think Grandma's stash), devs, experiments, and secure key handling (e.g., TAPSIGNER backups).
- **New**: #SeedVault - Encrypted multi-seed storage with easy recall. Supports TRNG, #DiceRolls, etc.
- **New**: #PSBTv2 - Enables advanced PSBT workflows and apps.
- **New**: #LockDownSeed - Compatible with all ephemeral secrets.
- **Name Change**: "Ephemeral Seed" is now "Temporary Seed."
- **New**: BIP39 Passphrase - Usable as a words-based ephemeral seed, supports encoded backups, and removes visibility post-activation for added security.
- **New**: Toggle between ephemeral and main secrets without a reboot.
- **New Shortcut**: Quick Batch Sign PSBT via Ready to Sign -> Press (9).
- **Cleanup**: Axed old code to free up space.
- **Improved**: Settings slots expanded to 100.
- **Fixed**: Off-by-one error in Trick Pins -> Login Countdown resolved.
- and more!
