A new versionb of fmt is out:

cppformat 3.0.0 and becomes fmt

by Victor Zverovich

From the release:

The project has been renamed from C++ Format (cppformat) to fmt for consistency with the used namespace and macro prefix (#307). Library headers are now located in the fmt directory:

#include "fmt/format.h"

Including format.h from the cppformat directory is deprecated but works via a proxy header which will be removed in the next major version. The documentation is now available at http://fmtlib.net...
