/// Pretty dirty hack.
///
/// For security reasons, `signature::DigestSigner` doesn't want you to sign raw bytes.
/// However, we have a trusted client, and want it to be able to send the raw bytes for efficiency,
/// also because the blockchain messages internally calculate and independently use the hash.
///
/// So... we need to have a structure that
/// a) acts like a real Sha256 if initiated with Default and then updated + finalized
/// b) returns our desired pre-existing hash as final output if initiated from that

Solo 2 firmware 1:20220317.0 pre-release

This firmware may break NFC, but should fix several outstanding issues with the existing 1.0.9 firmware bundle for Solo 2.

It uses the new "calver" representation of firmware versions, where 1:20220317.0 corresponds to the "semver" represeentation 1.806.0, with the middle item being the minor version component (806) interpreted as days since 2020-01-01, and major/patch version components corresponding directly.

Main changes:

  • shortened FIDO credential IDs (below 256 bytes), should work on all sites
  • improved memory management (previous firmwares often would crash due to stack overflow)
  • fixed/updated visual LED language for locked devices (red breathing for waiting, green blinking for processing, blue breathing for waiting on user touch, blue blinking for winking)

Gotcha:
