Continuing the discussion from Particle Firmware Update Thread:
I can no longer compile any code that uses String::format() as an argument:
Given this example from the docs:
Particle.publish("startup", String::format("frobnicator started at %s", Time.timeStr()));
Gives this compiler error:
error: cannot pass objects of non-trivially-copyable type 'class String' through '...'
Tested with both Build and Dev, after using CLI to OTA upgrade the device (so the cloud knows it is using 0.4.7)
