10.1.1 - 2023-08-26
-------------------
* Added formatters for ``std::atomic`` and ``atomic_flag``
(`#3574 <https://github.com/fmtlib/fmt/pull/3574>`_,
`#3594 <https://github.com/fmtlib/fmt/pull/3594>`_).
Thanks `@wangzw (Zhanwei Wang) <https://github.com/wangzw>`_ and
`@AlexGuteniev (Alex Guteniev) <https://github.com/AlexGuteniev>`_.
* Fixed an error about partial specialization of ``formatter<string>``
after instantiation when compiled with gcc and C++20
(`#3584 <https://github.com/fmtlib/fmt/issues/3584>`_).
* Fixed compilation as a C++20 module with gcc and clang
(`#3587 <https://github.com/fmtlib/fmt/issues/3587>`_,

10.0.0 - 2023-05-09
-------------------
* Replaced Grisu with a new floating-point formatting algorithm for given
precision (`#3262 <https://github.com/fmtlib/fmt/issues/3262>`_,
`#2750 <https://github.com/fmtlib/fmt/issues/2750>`_,
`#3269 <https://github.com/fmtlib/fmt/pull/3269>`_,
`#3276 <https://github.com/fmtlib/fmt/pull/3276>`_).
The new algorithm is based on Dragonbox already used for the
shortest representation and gives substantial performance improvement:

211956670-84891a09-6867-47d9-82fc-3230da7abe0f.png

implementation (`#3179 <https://github.com/fmtlib/fmt/pull/3179>`_,
`#3203 <https://github.com/fmtlib/fmt/pull/3203>`_).

Switched to the `modules CMake library <https://github.com/vitaut/modules>`_
which allows building {fmt} as a C++20 module with clang::
CXX=clang++ cmake -DFMT_MODULE=ON .
make
* Made ``format_as`` work with any user-defined type and not just enums.
For example (`godbolt <https://godbolt.org/z/b7rqhq5Kh>`__):

int main() {
fmt::print("{:8}\n", floaty_mc_floatface{0.42}); // prints " 0.42"
}
* Removed deprecated implicit conversions for enums and conversions to primitive
types for compatibility with ``std::format`` and to prevent potential ODR
violations. Use ``format_as`` instead.
* Added support for fill, align and width to the time point formatter

9.1.0 - 2022-08-27
------------------
* ``fmt::formatted_size`` now works at compile time
(`#3026 <https://github.com/fmtlib/fmt/pull/3026>`_). For example
(`godbolt <https://godbolt.org/z/1MW5rMdf8>`__):
.. code:: c++
#include <fmt/compile.h>
int main() {
using namespace fmt::literals;
constexpr size_t n = fmt::formatted_size("{}"_cf, 42);
fmt::print("{}\n", n); // prints 2
}

(`#2994 <https://github.com/fmtlib/fmt/pull/2994>`_).
Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_.

formatting ranges (`#2981 <https://github.com/fmtlib/fmt/pull/2981>`_,
`#2983 <https://github.com/fmtlib/fmt/pull/2983>`_).

Compile-Time Format String Checks
---------------------------------
Compile-time checks are enabled when using ``FMT_STRING``. They support built-in
and string types as well as user-defined types with ``constexpr`` ``parse``
functions in their ``formatter`` specializations.
Requires C++14 and is a no-op in C++11.
Compile-time format string checks are enabled by default on compilers
that support C++20 ``consteval``. On older compilers you can use the

To force the use of compile-time checks, define the preprocessor variable
``FMT_ENFORCE_COMPILE_STRING``. When set, functions accepting ``FMT_STRING``
will fail to compile with regular strings. Runtime-checked
formatting is still possible using ``fmt::vformat``, ``fmt::vprint``, etc.
Unused arguments are allowed as in Python's `str.format` and ordinary functions.

}

log(__FILE__, __LINE__, FMT_STRING(format), __VA_ARGS__)

times and reduces binary code size compared to a fully parameterized version.

The {fmt} library provides formatters for many standard C++ types.
See :ref:`fmt/ranges.h <ranges-api>` for ranges and tuples including standard
containers such as ``std::vector``, :ref:`fmt/chrono.h <chrono-api>` for date
and time formatting and :ref:`fmt/std.h <std-api>` for path and variant
formatting.
and time formatting and :ref:`fmt/std.h <std-api>` for other standard library
types.
To make a user-defined type formattable, specialize the ``formatter<T>`` struct
template and implement ``parse`` and ``format`` methods::
There are two ways to make a user-defined type formattable: providing a
``format_as`` function or specializing the ``formatter`` struct template.
Use ``format_as`` if you want to make your type formattable as some other type
with the same format specifiers. The ``format_as`` function should take an
object of your type and return an object of a formattable type. It should be
defined in the same namespace as your type.
Example (https://godbolt.org/z/r7vvGE1v7)::
#include <fmt/format.h>
namespace kevin_namespacy {
enum class film {
house_of_cards, american_beauty, se7en = 7
};
auto format_as(film f) { return fmt::underlying(f); }
}
int main() {
fmt::print("{}\n", kevin_namespacy::film::se7en); // prints "7"
}
Using the specialization API is more complex but gives you full control over
parsing and formatting. To use this method specialize the ``formatter`` struct
template for your type and implement ``parse`` and ``format`` methods.

If a type provides both a ``formatter`` specialization and an implicit
conversion to a formattable type, the specialization takes precedence over the
conversion.
Providing both a ``formatter`` specialization and a ``format_as`` overload is
disallowed.
For enums {fmt} also provides the ``format_as`` extension API. To format an enum
via this API define ``format_as`` that takes this enum and converts it to the
underlying type. ``format_as`` should be defined in the same namespace as the
enum.
