i made some minor pull request lately and during the process i stumbled uppon a question.
i read the Styleguide here and it was helpful. i try to use astyle for every commit.
But it does not say anything about what featues of c++14 i can use.
for example i saw that a lot of preprocessor defines used in mbed, i myself tent to use constexpr.
same for ifdef and if constexpr, or auto.
so my question is what is wanted by the maintainers. is it allowed to use more modern c++ or is it better to stick to a more classic approach and orient myself on the exitsting code so it does not get to messy.
Edit: another question is: since C++14 is nearly 6 years old should we go on and update to c++17?
