Today we are making available firmware 1.4.2 for the Nano S. This is the latest update in our continuous work to improve the security of Ledger devices.

The release includes a series of minor but meaningful updates. As such, this update is strongly recommended for all Nano S users.

This update makes the following improvements:

Improvement of the interaction between microcontroller (MCU) and secure element to remove confusing error message
Verification & checks of installed applications
Improved dashboard responsiveness

Details of the software update are included in our blog post, and all instructions are available in our step by step tutorial.
