SeedSigner v0.8.0

It's admittedly been a minute since our last release -- we've always built carefully and deliberately, and we continue to refine our software so bitcoiners everywhere can have a better and better permissionless signing device.

Quick Highlights:

Addtional legacy signing support:

• P2PKH (bip44): Legacy format dating back to 2014
• P2SH multisig (bip45): Legacy multisig (also 2014)

Quality-of-Life improvements ❤️

• New animated QR scanning UI + frame-by-frame feedback
• Much better animated QR scanning progress estimation calcs: no more stuck-at-99%-progress misery!
• Smarter rendering of outgoing animated QRs = faster reads by wallet software
• UX improvements when entering bip39 passphrases, verifying multisig change, etc.
• Two new community-created 3d-printable enclosure designs

Explicit support for PSBTs w/OP_RETURN

• displays the human-readable message or the raw hex data

Import Electrum Seeds 🌱

• Import an Electrum native segwit mnemonic, export xpub, sign txs.

Major code refactors, Github automations, MOAR TESTS🔥!

• Crucial yet unwieldy code got much more wieldy
• Awesome Github Actions integrations to automate test suite checks & generate custom SeedSigner OS images
• Significant upgrades to the test suite, both under the hood & overall test coverage

Notes:

Legacy multisig support enables full SeedSigner compatibility with Unchained vaults! (this is unofficial; don't expect Unchained customer support to be able to help you)

The new animated QR scanning UI is sexy (@easyuxd ftw!) and adds a green/gray feedback dot:

• Green = QR frame read, new data received
• Gray = QR frame read, but no new data
• No dot = wtf are you pointing at?

New Pro Tip: If your software coordinator seems stalled when reading a long outgoing animated QR, flick the SeedSigner joystick up/down. Why? The first few frames of an animated QR are the most valuable and they do NOT repeat. But now when you change your SeedSigner's outgoing QR code brightness (joystick up/down), those valuable frames are re-played.

Adding limited support for Electrum seeds is meant to help legacy/OG users eventually migrate away from Electrum and into more standardized wallet software. Full integration with Electrum is not planned.

Four .img files are included in the release; select the one that is appropriate for your Raspberry Pi hardware:

• "pi0.img" - For Raspberry Pi Zero v1.3 & Raspberry Pi Zero W
• "pi2.img" - For Raspberry Pi 2 Model B
• "pi02w.img" - For Raspberry Pi Zero 2 W & Raspberry Pi 3 Model B
• "pi4.img" - For Raspberry Pi 4 Model B

To install on your microSD card:

• Download the appropriate .img file
• Write the extracted image to a MicroSD card (32MB or larger)
• (make sure to use "dd" or a disk-authoring tool like Balena Etcher)
• Install the memory card in your signer

Checking your download for integrity and authenticity is super important -- with SeedSigner, you are the software authenticity assurance!
