7.1.0 - TBD
-----------
* Added a formatter for ``std::chrono::time_point<system_clock>``:
.. code:: c++
#include <fmt/chrono.h>
int main() {
auto now = std::chrono::system_clock::now();
fmt::print("The time is {:%H:%M:%S}.\n", now);
}
Thanks `@adamburgess (Adam Burgess) <https://github.com/adamburgess>`_.
* Added an experimental unsynchronized file output API which, together with
format string compilation, can give `5-9 times speed up compared to fprintf
<https://www.zverovich.net/2020/08/04/optimal-file-buffer-size.html>`__ on
common platforms:

* Added support for ranges with non-const ``begin``/``end`` to ``fmt::join``
(`#1784 <https://github.com/fmtlib/fmt/issues/1784)>`_,
`#1786 <https://github.com/fmtlib/fmt/pull/1786)>`_) For example

int main() {

auto strs = std::array{"a"s, "bb"s, "ccc"s};
auto range = strs | ranges::views::filter(
[] (const std::string &x) { return x.size() != 2; }
);
fmt::print("{}\n", fmt::join(range, ""));
}
prints "accc".
Thanks `@tonyelewis (Tony E Lewis) <https://github.com/tonyelewis>`_.
* Added a ``memory_buffer::append`` overload that takes a range
(`#1806 <https://github.com/fmtlib/fmt/pull/1806)>`_).
Thanks `@BRevzin (Barry Revzin) <https://github.com/BRevzin>`_.
* Improved handling of single code units in ``FMT_COMPILE``. For example:

Here a single ``mov`` instruction writes ``'x'`` (``$120``) to the output
buffer.
* Added dynamic width support to format string compilation
(`#1809 <https://github.com/fmtlib/fmt/issues/1809)>`_).
* Improved error reporting for unformattable types: now you'll get the type name
directly in the error message instead of the note:
