+* Added an experimental Grisu floating-point formatting algorithm
+  implementation (disabled by default). To enable it define ``FMT_USE_GRISU``
+  macro to 1 before including ``fmt/format.h``:

+  .. code:: c++
+
+     #define FMT_USE_GRISU 1
+     #include <fmt/format.h>
+
+     auto s = fmt::format("{}", 4.2); // formats 4.2 using Grisu
+
+  With Grisu enabled, {fmt} is 13x faster than ``std::ostringstream`` and
+  10x faster than ``sprintf`` on the `dtoa-benchmark
