Release v9.2.0 - Multi

⚠️ This is a pre-release candidate intended for testing. ⚠️

Testing is recommended with accounts holding only a small amount of funds. Make sure your backups work before use.

Release notes:

• New features:
  • Support for legacy segwit multisig. It uses legacy 3... addresses for backwards compatibility with services that do not yet support bech32 bc1... adresses.
  • Sign Bitcoin messages
  • Added a screensaver. It activates after ~1min of inactivity. Thanks @My1 for contributing the bouncing logo animation.
  • When signing a Bitcoin transaction, a progress bar now indicates progress when loading and signing the transaction.
  • Multisig account verification: allow verification of the xpubs in xpub... format instead of Zpub... or Ypub... formats
    Signing multi-line messages can now be verified more easily as each line is verified individually
• Autocomplete BIP39 words when restoring from recovery words (mnemonic)
• Allow editing previously entered words when restoring from recovery words, to fix typos
• Dropped the word bech32 from the receive screen.
• "Unlock device" screen can now be cancelled.
• Ported API calls to Rust: DeviceInfo, DeviceName, SetPassword, Reset, SetMnemonicPassphraseEnabled, InsertRemoveSdcard, CheckSdcard, CheckBackup, CreateBackup, ShowMnemonic
