# Post-C++14 TS Implementation Status

In April 2013, the C++ standard committee approved the draft for the next version of the C++ standard, known as "C++1Y" (probably to be C++14)

The draft standard includes papers and issues that were voted on at the previous three meetings (Kona, Portland, and Bristol)

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