There are more and more cases where if we do not use gcc-6.0 or later we run into problems where our binaries are too large for the targets. Given the prevalence of gcc-6.0 or later toolchains at this point in time, we give notice now that starting with v2018.01 we will require gcc-6 (or later) for ARM.
