Version 2.3

This release improves security once you've logged into the hardware wallet.
When you request a new address from the unit an OTP (one time passcode) is displayed on the screen of the unit. You have to enter this number in the GUI to verify that an automated attack isn't taking place.
When requesting a transaction to be signed the addresses and amounts are displayed on the screen of the hardware wallet. This helps to verify that the fields of the transaction weren't altered somewhere between Treasure Chest and the hardare wallet. The last step is to enter the OTP to authorise the transaction.

The stability of the Windows/Cygwin build was also improved.

The upgrade instructions are contained in the new file: UPGRADE.md

This release requires that the hardware wallet runs version 2.3 (communication=2, application=(3 or larger)). If you haven't yet requested the upgrade file you can do so by sending a private message to the ARRR address you've used when you've purchased your hardware wallet.
Alternatively, if you do not want to upgrade your hardware wallet, you'll have to downgrade the GUI application to version 1.2.
You can do this by commanding GIT to revert to an older release. Enter the command in your git repository:
   git checkout v1.2
You will have to recompile the project after the source code was altered.

To revert back to the head (top) of the branch, enter the command: git switch -
