compilation.
* Added the ``_cf`` user-defined literal to represent a
compiled format string. It can be used instead of the
``FMT_COMPILE`` macro.
* Format string compilation now requires ``format`` functions
of ``formatter`` specializations for user-defined types to
be ``const``.

* Improved locale handling in chrono formatting.
* Deprecated ``fmt/locale.h`` moving the formatting functions
that take a locale to ``fmt/format.h`` (``char``) and
``fmt/xchar`` (other overloads). This doesn't introduce a
dependency on ``<locale>`` so there is virtually no compile
time effect.

- Update to version 7.1.0
* Switched from Grisu3 to Dragonbox for the default
floating-point formatting which gives the shortest decimal
representation with round-trip guarantee and correct rounding.
This makes {fmt} up to 20-30x faster than common
implementations of std::ostringstream and sprintf on
dtoa-benchmark and faster than double-conversion and Ryū. It
is possible to get even better performance at the cost of
larger binary size by compiling with the
FMT_USE_FULL_CACHE_DRAGONBOX macro set to 1.
* Added an experimental unsynchronized file output API which,
together with format string compilation can give 5-9 times
speed up compared to fprintf on common platforms.
* Added a formatter for std::chrono::time_point<system_clock>
* Added support for ranges with non-const begin/end to fmt::join
* Added a memory_buffer::append overload that takes a range.
* Improved handling of single code units in FMT_COMPILE.
* Added dynamic width support to format string compilation.
* Improved error reporting for unformattable types: now you'll
get the type name directly in the error message instead of
the note.
* Added the make_args_checked function template that allows
you to write formatting functions with compile-time format
string checks and avoid binary code bloat.
* Replaced snprintf fallback with a faster internal IEEE 754
float and double formatter for arbitrary precision.
* Made format_to_n and formatted_size part of the core API.
* Added fmt::format_to_n overload with format string
compilation.
* Added fmt::format_to overload that take text_style.
* Made the # specifier emit trailing zeros in addition to the
decimal point.
* Changed the default floating point format to not include .0
for consistency with std::format and std::to_chars. It is
possible to get the decimal point and trailing zero with the
# specifier.
* Fixed an issue with floating-point formatting that could
result in addition of a non-significant trailing zero in
rare cases e.g. 1.00e-34 instead of 1.0e-34.
* Made fmt::to_string fallback on ostream insertion operator
if the formatter specialization is not provided.
* Added support for the append mode to the experimental file
API and improved fcntl.h detection.
* Fixed handling of types that have both an implicit
conversion operator and an overloaded ostream insertion
operator.
* Fixed a slicing issue in an internal iterator type.
* Fixed an issue in locale-specific integer formatting.
* Fixed handling of exotic code unit types.
* Improved FMT_ALWAYS_INLINE.
* Improved documentation.
* Added the FMT_REDUCE_INT_INSTANTIATIONS CMake option that
reduces the binary code size at the cost of some integer
formatting performance. This can be useful for extremely
memory-constrained embedded systems.
* Added the FMT_USE_INLINE_NAMESPACES macro to control usage
of inline namespaces.
* Improved build configuration.
* Fixed various warnings and compilation issues.

compilation and a stack-allocated buffer is now faster than
to_chars on both libc++ and libstdc++.
* Optimized handling of small format strings.
* Applied extern templates to improve compile times when using
the core API and fmt/format.h. It is still recommended to use
fmt/core.h instead of fmt/format.h but the compile time
difference is now smaller.

defined.
* Improved compatibility between fmt::printf with the standard
specs.

FMT_FUZZ macro to prevent interferring with fuzzing of
projects using {fmt}.

* Made CUDA test an opt-in enabled via the FMT_CUDA_TEST CMake
option.
* Fixed sign conversion warnings (#1440). Thanks @0x8000-0000
(Florin Iucha).
- Update to version 6.1.1
* Added a missing decimal point in exponent notation with
trailing zeros.
* Removed deprecated format_arg_store::TYPES.
- Update to version 6.1.0
* {fmt} now formats IEEE 754 ``float`` and ``double`` using
the shortest decimal representation with correct rounding by
default:
.. code:: c++
#include <cmath>
#include <fmt/core.h>
int main() {
fmt::print("{}", M_PI);
}
prints ``3.141592653589793``.
* Made the fast binary to decimal floating-point formatter the
default, simplified it and improved performance. {fmt} is now
15 times faster than libc++'s ``std::ostringstream``, 11
times faster than ``printf`` and 10% faster than
double-conversion on `dtoa-benchmark
(https://github.com/fmtlib/dtoa-benchmark)
================== ========= =======
Function Time (ns) Speedup
================== ========= =======
ostringstream 1,346.30 1.00x
ostrstream 1,195.74 1.13x
sprintf 995.08 1.35x
doubleconv 99.10 13.59x
fmt 88.34 15.24x
================== ========= =======
* {fmt} no longer converts ``float`` arguments to ``double``.
In particular this improves the default (shortest)
representation of floats and makes
``fmt::format`` consistent with ``std::format`` specs
(#1336, #1353, #1360, #1361)
.. code:: c++
fmt::print("{}", 0.1f);
prints ``0.1`` instead of ``0.10000000149011612``.
* Made floating-point formatting output consistent with
``printf``/iostreams (#1376, #1417)
* Added support for 128-bit integers (#1287)
.. code:: c++
fmt::print("{}", std::numeric_limits<__int128_t>::max());
prints ``170141183460469231731687303715884105727``.
* The overload of ``print`` that takes ``text_style`` is now
atomic, i.e. the output from different threads doesn't
interleave (#1351)
* Made compile time in the header-only mode ~20% faster by
reducing the number of template instantiations. ``wchar_t``
overload of ``vprint`` was moved from
``fmt/core.h`` to ``fmt/format.h``.
* Added an overload of ``fmt::join`` that works with tuples
(#1322, #1330)
.. code:: c++
#include <tuple>
#include <fmt/ranges.h>
int main() {
std::tuple<char, int, float> t{'a', 1, 2.0f};
fmt::print("{}", t);
}
prints ``('a', 1, 2.0)``.
* Changed formatting of octal zero with prefix from "0o0" to
"0":
.. code:: c++
fmt::print("{:#o}", 0);
prints ``0``.
* The locale is now passed to ostream insertion (``<<``)
operators (#1406)
.. code:: c++
#include <fmt/locale.h>
#include <fmt/ostream.h>
struct S {
double value;
};
std::ostream& operator<<(std::ostream& os, S s) {
return os << s.value;
}
int main() {
auto s = fmt::format(std::locale("fr_FR.UTF-8"), "{}", S{0.42});
// s == "0,42"
}
* Locale-specific number formatting now uses grouping (#1393,
#1394)
* Fixed handling of types with deleted implicit rvalue
conversion to ``const char**`` (#1421)
.. code:: c++
