If your internet flickered during a flash, 5.x might interrupt the write process. 4.12.4 performs its license check at startup and during the initial read, but during the actual write to the ECU, it is far less intrusive. This makes it the preferred version for tuners working in rural areas or underground dyno cells with poor Wi-Fi.
The most prominent feature of the 4.12.x branch was the expansion of support for General Motors' Global B and Global D platforms.
