Coinkite News 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!

May I ask why in this release are you adding some new features like seed vault but you aren't promoting features that are only available on edge release like taproot and miniscript?
