I don't know what you mean with "the last update" but, in the LAST update, we added precisely the option users has been asking for, that is the ability to turn off the "annoying voice".
Nobody ever reported an "hot brakes" issue in P3D, it's used to be a problem with the Fenix A320 in MSFS, but they fixed it so, it would have been helpful if you said WHICH 3rd party airplane shows this problem, which can only be fixed by the airplane developers, since the brakes temperature is not a standard system, it's always something custom.
About the "script engine crash", where's your crash log ?
