Post-C++14 TS Implementation Status

In November 2014, the C++ standard committee approved the draft for the next version of the C++ standard, known as "C++1z" (probably to be C++17)

In addition, there are several "Technical Specifications", that consist of new features that are proposed, but not yet accepted for C++1z.

This page shows the status of libc++; the status of clang's support of the language features is here.
