STL support for C++ ARMCC compiler 5 and 6

For ARMCC5 here I can find the C++ supported features.

I see that additions to the C++11 standard template library are NOT supporte.

ARM® Compiler 5 includes only the C++03 standard template library.

And so std::array is not supported by ARMCC6.

For ARMCC 6 I read that

It fully supports the C++14 language standard.

Does this mean that the whole C++ STL is already supported in ARMCC 6?

I'm almost interested in std::array

Which are the disadavantages in migrating the code to the new ARMCC 6?

Is an official release? Or is it a kind of beta?
