     70 Bug Fixes in 2.5-DNX compared to 2.5:
     71   Make the DNX devices supported in this release, able to check the firmware
     72   version and load a different firmware version to QSPI flash memory from the
     73   SDK.
     74   Fix custom settings handling (if provided by the customer) to not report
     75   incorrect failures of their application.
     76 
     77 Bug Fixes in 2.5:
     78   Fix for device enumeration fail sporadically when set to Gen3 mode.
