Is GCC ready for C++14 production code?

In this web page, GCC's support for the ISO C++14 standard is defined "experimental".

Since I'd like to use some of the C++14's improvements on C++11 (e.g. std::make_unique and generic lambdas) in my C++ code, am I safe in using the -std=c++14 option with GCC 4.9 for production code, or is current GCC/C++14 status kind of like "beta" and so GCC/C++14 not ready for production code?
