CRYPTO-BOX: New Firmware

Starting in November 2020, all CRYPTO-BOX units will be shipped with new firmware.

The new version numbers are 3.1 for CRYPTO-BOX XS/Versa, and resp. 4.1 for CRYPTO-BOX SC. They come with the following up-grades:

• Improved stability at power interruptions, caused by voltage fluctuations or power dropouts
• Enhanced compatibility with various USB controllers

Firmware 3.1 and 4.1 are fully compatible with the existing 3.0/4.0 firmware version. No changes on the software side are required. The only visible difference is the return value of the firmware version by the API.
