libc++ C++2a Status
In July 2017, the C++ standard committee created a draft for the next version of the C++ standard, known here as "C++2a" (probably to be C++20).
This page shows the status of libc++; the status of clang's support of the language features is here.
The groups that have contributed papers:
- LWG - Library working group
- CWG - Core Language Working group
- SG1 - Study group #1 (Concurrency working group)
