Towards the very end of 2011, new versions of the C and C++ standards were released. The last time this happened was 1999 for C and 2003 for C++, so this is far from a regular occurrence. Much of the discussion of the support has focussed on the compiler, but both C and C++ have a large standard library. The C standard library is a core part of any UNIX system - the public system call interface is specified in terms of functions in this library - and so the task of bringing this support to users falls to a mixture of libc, the compiler, and a few other supporting pieces of code.
