v1.5.6

Minor bugfixes.

Release notes:

• Fix deleting key from SD card (#164) (@EndNationStates)
• Disallow empty names for seeds and wallets (#165) (@stepansnigirev)

If you have firmware v1.4.0 or later you need to copy specter_upgrade_v1.5.6.bin to the SD card and insert it into the device. The bootloader will check the signatures of the upgrade file and update firmware.

If your discovery board is empty or you have very old firmware (below 1.4.0) - just copy-paste initial_firmware_v1.5.6.bin file to your board when it's connected over miniUSB.

v1.5.5

Release notes:

• Store multiple seeds on internal flash or SD card, export seeds as plaintext (#149) (@EndNationStates)
• Recover from a plaintext seed (content of the .txt file or QR code should be in a form bip39: <your recovery phrase>) (a2e89e3) (@EndNationStates)
• Change smartcards without reboot to backup keys on multiple cards (requires PIN code before swapping cards) (ffcdd42) (@stepansnigirev)
• Allow partial derivations in transactions for wallet lookup - you can use just xpub without derivations and the device will be able to sign (#163) (@stepansnigirev)
• Create single-sig wallets from the UI of Specter-DIY directly (#161) (@stepansnigirev)
• Anti-phishing words fix not to crop the second line (#155) (@EndNationStates)
• Change bip39 word numbers to start from 1 and move Show mnemonic up (#157) (@moneymanolis)
• Export master public keys in bulk as json or text (#148) (@EndNationStates)
• Add cancel button to PIN screen when possible (#146) (@EndNationStates)
