  • 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.
