Hi,

The main difference is that in the latest revision access port protection is improved. Due to changes in the MDK there is a requirement to use firmware based on nRF5 SDK 17.1.0 or later or nRF Connect SDK 1.6.0 or later. If you are using a older SDK (which shipped with an older MDK), you need to migrate your application to use MDK 8.40.2 or later. See IN-142 for more information.
