+8.0.0 - TBD
+-----------
+
+* Added compile-time formatting
+ (`#2019 <https://github.com/fmtlib/fmt/pull/2019>`_,
+ `#2044 <https://github.com/fmtlib/fmt/pull/2044>`_,
+ `#2056 <https://github.com/fmtlib/fmt/pull/2056>`_,
+ `#2072 <https://github.com/fmtlib/fmt/pull/2072>`_,
+ `#2075 <https://github.com/fmtlib/fmt/pull/2075>`_,
+ `#2078 <https://github.com/fmtlib/fmt/issues/2078>`_,
+ `#2129 <https://github.com/fmtlib/fmt/pull/2129>`_,
+ `#2326 <https://github.com/fmtlib/fmt/pull/2326>`_).
+ For example (`godbolt <https://godbolt.org/z/Mxx9d89jM>`__):
+
+ .. code:: c++
+
+ #include <fmt/compile.h>
+
+ consteval auto compile_time_itoa(int value) -> std::array<char, 10> {
+ auto result = std::array<char, 10>();
+ fmt::format_to(result.data(), FMT_COMPILE("{}"), value);
+ return result;
+ }
+
+ constexpr auto answer = compile_time_itoa(42);
+
+ Most of the formatting functionality is available at compile time with a
+ notable exception of floating-point numbers and pointers.
+ Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
+
+* Optimized handling of format specifiers during format string compilation.
+ For example, hexadecimal formatting (``"{:x}"``) is now 3-7x faster than
+ before when using ``format_to`` with format string compilation and a
+ stack-allocated buffer (`#1944 <https://github.com/fmtlib/fmt/issues/1944>`_).
+

+ ----------------------------------------------------------------------------
+
+ And even faster than ``std::to_chars`` from libc++ compiled with clang on
+ macOS::

+ ToChars/9223372036854775807 8.77 ns 8.75 ns 75872534
+ ----------------------------------------------------------------------------
+
+ In other cases, especially involving ``std::string`` construction, the
+ speed up is usually lower because handling format specifiers takes a smaller
+ fraction of the total time.
+
+* Added the ``_cf`` user-defined literal to represent a compiled format string.
+ It can be used instead of the ``FMT_COMPILE`` macro
+ (`#2043 <https://github.com/fmtlib/fmt/pull/2043>`_,
+ `#2242 <https://github.com/fmtlib/fmt/pull/2242>`_):
+
+ .. code:: c++
+
+ #include <fmt/compile.h>
+
+ using namespace fmt::literals;
+ auto s = fmt::format(FMT_COMPILE("{}"), 42); // 🙁 not modern
+ auto s = fmt::format("{}"_cf, 42); // 🙂 modern as hell
+
+ It requires compiler support for class types in non-type template parameters
+ (a C++20 feature) which is available in GCC 9.3+.
+ Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
+
+* Format string compilation now requires ``format`` functions of ``formatter``
+ specializations for user-defined types to be ``const``:
+
+ .. code:: c++
+
+ template <> struct fmt::formatter<my_type>: formatter<string_view> {
+ template <typename FormatContext>
+ auto format(my_type obj, FormatContext& ctx) const { // Note const here.
+ // ...
+ }
+ };
+
+* Added UDL-based named argument support to format string compilation
+ (`#2243 <https://github.com/fmtlib/fmt/pull/2243>`_,
+ `#2281 <https://github.com/fmtlib/fmt/pull/2281>`_). For example:
+
+ .. code:: c++
+
+ #include <fmt/compile.h>
+
+ using namespace fmt::literals;
+ auto s = fmt::format(FMT_COMPILE("{answer}"), "answer"_a = 42);
+
+ Here the argument named "answer" is resolved at compile time with no
+ runtime overhead.
+ Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
+
+* Added format string compilation support to ``fmt::print``
+ (`#2280 <https://github.com/fmtlib/fmt/issues/2280>`_,
+ `#2304 <https://github.com/fmtlib/fmt/pull/2304>`_).
+ Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
+
+* Added initial support for compiling {fmt} as a C++20 module
+ (`#2235 <https://github.com/fmtlib/fmt/pull/2235>`_,
+ `#2240 <https://github.com/fmtlib/fmt/pull/2240>`_,
+ `#2260 <https://github.com/fmtlib/fmt/pull/2260>`_,
+ `#2282 <https://github.com/fmtlib/fmt/pull/2282>`_,
+ `#2283 <https://github.com/fmtlib/fmt/pull/2283>`_,
+ `#2288 <https://github.com/fmtlib/fmt/pull/2288>`_,
+ `#2298 <https://github.com/fmtlib/fmt/pull/2298>`_,
+ `#2306 <https://github.com/fmtlib/fmt/pull/2306>`_,
+ `#2307 <https://github.com/fmtlib/fmt/pull/2307>`_,
+ `#2309 <https://github.com/fmtlib/fmt/pull/2309>`_,
+ `#2318 <https://github.com/fmtlib/fmt/pull/2318>`_,
+ `#2324 <https://github.com/fmtlib/fmt/pull/2324>`_,
+ `#2332 <https://github.com/fmtlib/fmt/pull/2332>`_).
+ Thanks `@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.
+
+* Made symbols private by default reducing shared library size
+ (`#2301 <https://github.com/fmtlib/fmt/pull/2301>`_). For example there was
+ a ~15% reported reduction on one platform.
+ Thanks `@sergiud (Sergiu Deitsch) <https://github.com/sergiud>`_.
+
+* Optimized includes making the result of preprocessing ``fmt/format.h``
+ ~20% smaller with libstdc++/C++20 and slightly improving build times
+ (`#1998 <https://github.com/fmtlib/fmt/issues/1998>`_).
+
+* Added support of ranges with non-const ``begin`` / ``end``
+ (`#1953 <https://github.com/fmtlib/fmt/pull/1953>`_).
+ Thanks `@kitegi (sarah) <https://github.com/kitegi>`_.
+
+* Added support of ``std::byte`` and other formattable types to ``fmt::join``
+ (`#1981 <https://github.com/fmtlib/fmt/issues/1981>`_,
+ `#2040 <https://github.com/fmtlib/fmt/issues/2040>`_,
+ `#2050 <https://github.com/fmtlib/fmt/pull/2050>`_,
+ `#2262 <https://github.com/fmtlib/fmt/issues/2262>`_). For example:
+
+ .. code:: c++
+
+ #include <fmt/format.h>
+ #include <cstddef>
+ #include <vector>
+
+ int main() {
+ auto bytes = std::vector{std::byte(4), std::byte(2)};
+ fmt::print("{}", fmt::join(bytes, ""));
+ }
+
+ prints "42".
+
+ Thanks `@kamibo (Camille Bordignon) <https://github.com/kamibo>`_.
+
+* Made more chrono specifiers locale independent by default. Use the ``'L'``
+ specifier to get localized formatting. For example:
+
+ .. code:: c++
+
+ #include <fmt/chrono.h>
+
+ int main() {
+ std::locale::global(std::locale("ru_RU.UTF-8"));
+ auto monday = std::chrono::weekday(1);
+ fmt::print("{}\n", monday); // prints "Mon"
+ fmt::print("{:L}\n", monday); // prints "пн"
+ }
+
+* 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.
+
+* Made parameter order in ``vformat_to`` consistent with ``format_to``
+ (`#2327 <https://github.com/fmtlib/fmt/issues/2327>`_).
+
+* Added support for time points with arbitrary durations
+ (`#2208 <https://github.com/fmtlib/fmt/issues/2208>`_). For example:
+
+ .. code:: c++
+
+ #include <fmt/chrono.h>
+
+ int main() {
+ using tp = std::chrono::time_point<
+ std::chrono::system_clock, std::chrono::seconds>;
+ fmt::print("{:%S}", tp(std::chrono::seconds(42)));
+ }
+
+ prints "42".
+
+* Formatting floating-point numbers no longer produces trailing zeros by default
+ for consistency with ``std::format``. For example:
+
+ .. code:: c++
+
+ #include <fmt/core.h>
+
+ int main() {
+ fmt::print("{0:.3}", 1.1);
+ }
+
+ prints "1.1". Use the ``'#'`` specifier to keep trailing zeros.
+
+* Dropped a limit on the number of elements in a range and replaced ``{}`` with
+ ``[]`` as range delimiters for consistency with Python's ``str.format``.
+
+* The ``'L'`` specifier for locale-specific numeric formatting can now be
+ combined with presentation specifiers as in ``std::format``. For example:
+
+ .. code:: c++
+
+ #include <fmt/core.h>
+ #include <locale>
+
+ int main() {
+ std::locale::global(std::locale("fr_FR.UTF-8"));
+ fmt::print("{0:.2Lf}", 0.42);
+ }
+
+ prints "0,42". The deprecated ``'n'`` specifier has been removed.
+
+* Made the ``0`` specifier ignored for infinity and NaN
+ (`#2305 <https://github.com/fmtlib/fmt/issues/2305>`_,
+ `#2310 <https://github.com/fmtlib/fmt/pull/2310>`_).
+ Thanks `@Liedtke (Matthias Liedtke) <https://github.com/Liedtke>`_.
+
+* Made the hexfloat formatting use the right alignment by default
+ (`#2308 <https://github.com/fmtlib/fmt/issues/2308>`_,
+ `#2317 <https://github.com/fmtlib/fmt/pull/2317>`_).
+ Thanks `@Liedtke (Matthias Liedtke) <https://github.com/Liedtke>`_.
+
+* Removed the deprecated numeric alignment (``'='``). Use the ``'0'`` specifier
+ instead.
+
+* Removed the deprecated ``fmt/posix.h`` header that has been replaced with
+ ``fmt/os.h``.
+
+* Removed the deprecated ``format_to_n_context``, ``format_to_n_args`` and
+ ``make_format_to_n_args``. They have been replaced with ``format_context``,
+ ``format_args` and ``make_format_args`` respectively.
+
+* Moved ``wchar_t``-specific functions and types to ``fmt/wchar.h``.
+ You can define ``FMT_DEPRECATED_INCLUDE_WCHAR`` to automatically include
+ ``fmt/wchar.h`` from ``fmt/format.h`` but this will be disabled in the next
+ major release.
+
+* Fixed handling of the ``'+'`` specifier in localized formatting
+ (`#2133 <https://github.com/fmtlib/fmt/issues/2133>`_).
+
+* Added support for the ``'s'`` format specifier that gives textual
+ representation of ``bool``
+ (`#2094 <https://github.com/fmtlib/fmt/issues/2094>`_,
+ `#2109 <https://github.com/fmtlib/fmt/pull/2109>`_). For example:
+
+ .. code:: c++
+
+ #include <fmt/core.h>
+
+ int main() {
+ fmt::print("{:s}", true);
+ }
+
+ prints "true".
+ Thanks `@powercoderlol (Ivan Polyakov) <https://github.com/powercoderlol>`_.
+
+* Made ``fmt::ptr`` work with function pointers
+ (`#2131 <https://github.com/fmtlib/fmt/pull/2131>`_). For example:
+
+ .. code:: c++
+
+ #include <fmt/format.h>
+
+ int main() {
+ fmt::print("My main: {}\n", fmt::ptr(main));
+ }
+
+ Thanks `@mikecrowe (Mike Crowe) <https://github.com/mikecrowe>`_.
+
+* Fixed ``fmt::formatted_size`` with format string compilation
+ (`#2141 <https://github.com/fmtlib/fmt/pull/2141>`_,
+ `#2161 <https://github.com/fmtlib/fmt/pull/2161>`_).
+ Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
+
+* Fixed handling of empty format strings during format string compilation
+ (`#2042 <https://github.com/fmtlib/fmt/issues/2042>`_):
+
+ .. code:: c++
+
+ auto s = fmt::format(FMT_COMPILE(""));
+
+ Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
+
+* Fixed handling of enums in ``fmt::to_string``
+ (`#2036 <https://github.com/fmtlib/fmt/issues/2036>`_).
+
+* Improved width computation
+ (`#2033 <https://github.com/fmtlib/fmt/issues/2033>`_,
+ `#2091 <https://github.com/fmtlib/fmt/issues/2091>`_). For example:
+
+ .. code:: c++
+
+ #include <fmt/core.h>
+
+ int main() {
+ fmt::print("{:-<10}{}\n", "你好", "世界");
+ fmt::print("{:-<10}{}\n", "hello", "world");
+ }
+
+ prints
+
+ .. image:: https://user-images.githubusercontent.com/576385/
+ 119840373-cea3ca80-beb9-11eb-91e0-54266c48e181.png
+
+ on a modern terminal.
+
+* The experimental fast output stream (``fmt::ostream``) is now truncated by
+ default for consistency with ``fopen``
+ (`#2018 <https://github.com/fmtlib/fmt/issues/2018>`_). For example:
+
+ .. code:: c++
+
+ #include <fmt/os.h>
+
+ int main() {
+ fmt::ostream out1 = fmt::output_file("guide");
+ out1.print("Zaphod");
+ out1.close();
+ fmt::ostream out2 = fmt::output_file("guide");
+ out2.print("Ford");
+ }
+
+ writes "Ford" to the file "guide". To preserve the old file content if any
+ pass ``fmt::file::WRONLY | fmt::file::CREATE`` flags to ``fmt::output_file``.
+
+* Fixed moving of ``fmt::ostream`` that holds buffered data
+ (`#2197 <https://github.com/fmtlib/fmt/issues/2197>`_,
+ `#2198 <https://github.com/fmtlib/fmt/pull/2198>`_).
+ Thanks `@vtta <https://github.com/vtta>`_.
+
+* Replaced the ``fmt::system_error`` exception with a function of the same
+ name that constructs ``std::system_error``
+ (`#2266 <https://github.com/fmtlib/fmt/issues/2266>`_).
+
+* Replaced the ``fmt::windows_error`` exception with a function of the same
+ name that constructs ``std::system_error`` with the category returned by
+ ``fmt::system_category()``
+ (`#2274 <https://github.com/fmtlib/fmt/issues/2274>`_,
+ `#2275 <https://github.com/fmtlib/fmt/pull/2275>`_).
+ The latter is similar to ``std::sytem_category`` but correctly handles UTF-8.
+ Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_.
+
+* Replaced ``fmt::error_code`` with ``std::error_code`` and made it formattable
+ (`#2269 <https://github.com/fmtlib/fmt/issues/2269>`_,
+ `#2270 <https://github.com/fmtlib/fmt/pull/2270>`_,
+ `#2273 <https://github.com/fmtlib/fmt/pull/2273>`_).
+ Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_.
+
+* Added speech synthesis support
+ (`#2206 <https://github.com/fmtlib/fmt/pull/2206>`_).
+
+* Made ``format_to`` work with a memory buffer that has a custom allocator
+ (`#2300 <https://github.com/fmtlib/fmt/pull/2300>`_).
+ Thanks `@voxmea <https://github.com/voxmea>`_.
+
+* Added ``Allocator::max_size`` support to ``basic_memory_buffer``.
+ (`#1960 <https://github.com/fmtlib/fmt/pull/1960>`_).
+ Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_.
+
+* Added wide string support to ``fmt::join``
+ (`#2236 <https://github.com/fmtlib/fmt/pull/2236>`_).
+ Thanks `@crbrz <https://github.com/crbrz>`_.
+
+* Made iterators passed to ``formatter`` specializations via a format context
+ satisfy C++20 ``std::output_iterator`` requirements
+ (`#2156 <https://github.com/fmtlib/fmt/issues/2156>`_,
+ `#2158 <https://github.com/fmtlib/fmt/pull/2158>`_,
+ `#2195 <https://github.com/fmtlib/fmt/issues/2195>`_,
+ `#2204 <https://github.com/fmtlib/fmt/pull/2204>`_).
+ Thanks `@randomnetcat (Jason Cobb) <https://github.com/randomnetcat>`_.
+
+* Optimized the ``printf`` implementation
+ (`#1982 <https://github.com/fmtlib/fmt/pull/1982>`_,
+ `#1984 <https://github.com/fmtlib/fmt/pull/1984>`_,
+ `#2016 <https://github.com/fmtlib/fmt/pull/2016>`_,
+ `#2164 <https://github.com/fmtlib/fmt/pull/2164>`_).
+ Thanks `@rimathia <https://github.com/rimathia>`_ and
+ `@moiwi <https://github.com/moiwi>`_.
+
+* Improved detection of ``constexpr`` ``char_traits``
+ (`#2246 <https://github.com/fmtlib/fmt/pull/2246>`_,
+ `#2257 <https://github.com/fmtlib/fmt/pull/2257>`_).
+ Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_.
+
+* Fixed writing to ``stdout`` when it is redirected to ``NUL`` on Windows
+ (`#2080 <https://github.com/fmtlib/fmt/issues/2080>`_).
+
+* Fixed exception propagation from iterators
+ (`#2097 <https://github.com/fmtlib/fmt/issues/2097>`_).
+
+* Improved ``strftime`` error handling
+ (`#2238 <https://github.com/fmtlib/fmt/issues/2238>`_,
+ `#2244 <https://github.com/fmtlib/fmt/pull/2244>`_).
+ Thanks `@yumeyao <https://github.com/yumeyao>`_.
+
+* Stopped using deprecated GCC UDL template extension.
+
+* Added ``fmt/args.h`` to the install target
+ (`#2096 <https://github.com/fmtlib/fmt/issues/2096>`_).
+
+* Error messages are now passed to assert when exceptions are disabled
+ (`#2145 <https://github.com/fmtlib/fmt/pull/2145>`_).
+ Thanks `@NobodyXu (Jiahao XU) <https://github.com/NobodyXu>`_.
+
+* Added the ``FMT_MASTER_PROJECT`` CMake option to control build and install
+ targets when {fmt} is included via ``add_subdirectory``
+ (`#2098 <https://github.com/fmtlib/fmt/issues/2098>`_,
+ `#2100 <https://github.com/fmtlib/fmt/pull/2100>`_).
+ Thanks `@randomizedthinking <https://github.com/randomizedthinking>`_.
+
+* Improved build configuration
+ (`#2026 <https://github.com/fmtlib/fmt/pull/2026>`_,
+ `#2122 <https://github.com/fmtlib/fmt/pull/2122>`_).
+ Thanks `@luncliff (Park DongHa) <https://github.com/luncliff>`_ and
+ `@ibaned (Dan Ibanez) <https://github.com/ibaned>`_.
+
+* Fixed various warnings and compilation issues
+ (`#1947 <https://github.com/fmtlib/fmt/issues/1947>`_,

+
+7.1.3 - 2020-11-24
+------------------
+
+* Fixed handling of buffer boundaries in ``format_to_n``
+ (`#1996 <https://github.com/fmtlib/fmt/issues/1996>`_,
+ `#2029 <https://github.com/fmtlib/fmt/issues/2029>`_).
+
+* Fixed linkage errors when linking with a shared library
+ (`#2011 <https://github.com/fmtlib/fmt/issues/2011>`_).
+
+* Reintroduced ostream support to range formatters
+ (`#2014 <https://github.com/fmtlib/fmt/issues/2014>`_).
+
+* Worked around an issue with mixing std versions in gcc
+ (`#2017 <https://github.com/fmtlib/fmt/issues/2017>`_).
+
+7.1.2 - 2020-11-04
+------------------
+
+* Fixed floating point formatting with large precision
+ (`#1976 <https://github.com/fmtlib/fmt/issues/1976>`_).
+
+7.1.1 - 2020-11-01
+------------------
+
+* Fixed ABI compatibility with 7.0.x
+ (`#1961 <https://github.com/fmtlib/fmt/issues/1961>`_).
+
+* Added the ``FMT_ARM_ABI_COMPATIBILITY`` macro to work around ABI
+ incompatibility between GCC and Clang on ARM
+ (`#1919 <https://github.com/fmtlib/fmt/issues/1919>`_).
+
+* Worked around a SFINAE bug in GCC 8
+ (`#1957 <https://github.com/fmtlib/fmt/issues/1957>`_).
+
+* Fixed linkage errors when building with GCC's LTO
+ (`#1955 <https://github.com/fmtlib/fmt/issues/1955>`_).
+
+* Fixed a compilation error when building without ``__builtin_clz`` or equivalent
+ (`#1968 <https://github.com/fmtlib/fmt/pull/1968>`_).
+ Thanks `@tohammer (Tobias Hammer) <https://github.com/tohammer>`_.
+
+* Fixed a sign conversion warning
+ (`#1964 <https://github.com/fmtlib/fmt/pull/1964>`_).
+ Thanks `@OptoCloud <https://github.com/OptoCloud>`_.
+
+7.1.0 - 2020-10-25
+------------------
+
+* Switched from `Grisu3
+ <https://www.cs.tufts.edu/~nr/cs257/archive/florian-loitsch/printf.pdf>`_
+ to `Dragonbox <https://github.com/jk-jeon/dragonbox>`_ for the default
+ floating-point formatting which gives the shortest decimal representation
+ with round-trip guarantee and correct rounding
+ (`#1882 <https://github.com/fmtlib/fmt/pull/1882>`_,
+ `#1887 <https://github.com/fmtlib/fmt/pull/1887>`_,
+ `#1894 <https://github.com/fmtlib/fmt/pull/1894>`_). This makes {fmt} up to
+ 20-30x faster than common implementations of ``std::ostringstream`` and
+ ``sprintf`` on `dtoa-benchmark <https://github.com/fmtlib/dtoa-benchmark>`_
+ and faster than double-conversion and Ryū:
+
+ .. image:: https://user-images.githubusercontent.com/576385/
+ 95684665-11719600-0ba8-11eb-8e5b-972ff4e49428.png
+
+ 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.
+
+ Thanks `@jk-jeon (Junekey Jeon) <https://github.com/jk-jeon>`_.
+
+* Added an experimental unsynchronized file output API which, together with
+ `format string compilation <https://fmt.dev/latest/api.html#compile-api>`_,
+ 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 (`godbolt <https://godbolt.org/z/nsTcG8>`__):
+
+ .. code:: c++
+
+ #include <fmt/os.h>
+
+ int main() {
+ auto f = fmt::output_file("guide");
+ f.print("The answer is {}.", 42);
+ }
+
+* Added a formatter for ``std::chrono::time_point<system_clock>``
+ (`#1819 <https://github.com/fmtlib/fmt/issues/1819>`_,
+ `#1837 <https://github.com/fmtlib/fmt/pull/1837>`_). For example
+ (`godbolt <https://godbolt.org/z/c4M6fh>`__):
+
+ .. 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 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
+ (`godbolt <https://godbolt.org/z/jP63Tv>`__):
+
+ .. code:: c++
+
+ #include <fmt/ranges.h>
+ #include <range/v3/view/filter.hpp>
+
+ int main() {
+ using std::literals::string_literals::operator""s;
+ 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:
+
+ .. code:: c++
+
+ #include <fmt/compile.h>
+
+ char* f(char* buf) {
+ return fmt::format_to(buf, FMT_COMPILE("x{}"), 42);
+ }
+
+ compiles to just (`godbolt <https://godbolt.org/z/5vncz3>`__):
+
+ .. code:: asm
+
+ _Z1fPc:
+ movb $120, (%rdi)
+ xorl %edx, %edx
+ cmpl $42, _ZN3fmt2v76detail10basic_dataIvE23zero_or_powers_of_10_32E+8(%rip)
+ movl $3, %eax
+ seta %dl
+ subl %edx, %eax
+ movzwl _ZN3fmt2v76detail10basic_dataIvE6digitsE+84(%rip), %edx
+ cltq
+ addq %rdi, %rax
+ movw %dx, -2(%rax)
+ ret
+
+ 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:
+
+ .. code:: c++
+
+ #include <fmt/core.h>
+
+ struct how_about_no {};
+
+ int main() {
+ fmt::print("{}", how_about_no());
+ }
+
+ Error (`godbolt <https://godbolt.org/z/GoxM4e>`__):
+
+ ``fmt/core.h:1438:3: error: static_assert failed due to requirement
+ 'fmt::v7::formattable<how_about_no>()' "Cannot format an argument.
+ To make type T formattable provide a formatter<T> specialization:
+ https://fmt.dev/latest/api.html#udt"
+ ...``
+
+* Added the `make_args_checked <https://fmt.dev/7.1.0/api.html#argument-lists>`_
+ function template that allows you to write formatting functions with
+ compile-time format string checks and avoid binary code bloat
+ (`godbolt <https://godbolt.org/z/PEf9qr>`__):
+
+ .. code:: c++
+
+ void vlog(const char* file, int line, fmt::string_view format,
+ fmt::format_args args) {
+ fmt::print("{}: {}: ", file, line);
+ fmt::vprint(format, args);
+ }
+
+ template <typename S, typename... Args>
+ void log(const char* file, int line, const S& format, Args&&... args) {
+ vlog(file, line, format,
+ fmt::make_args_checked<Args...>(format, args...));
+ }
+
+ #define MY_LOG(format, ...) \
+ log(__FILE__, __LINE__, FMT_STRING(format), __VA_ARGS__)
+
+ MY_LOG("invalid squishiness: {}", 42);
+
+* Replaced ``snprintf`` fallback with a faster internal IEEE 754 ``float`` and
+ ``double`` formatter for arbitrary precision. For example
+ (`godbolt <https://godbolt.org/z/dPhWvj>`__):
+
+ .. code:: c++
+
+ #include <fmt/core.h>
+
+ int main() {
+ fmt::print("{:.500}\n", 4.9406564584124654E-324);
+ }
+
+ prints
+
+ ``4.9406564584124654417656879286822137236505980261432476442558568250067550727020875186529983636163599237979656469544571773092665671035593979639877479601078187812630071319031140452784581716784898210368871863605699873072305000638740915356498438731247339727316961514003171538539807412623856559117102665855668676818703956031062493194527159149245532930545654440112748012970999954193198940908041656332452475714786901472678015935523861155013480352649347201937902681071074917033322268447533357208324319360923829e-324``.
+
+* Made ``format_to_n`` and ``formatted_size`` part of the `core API
+ <https://fmt.dev/latest/api.html#core-api>`__
+ (`godbolt <https://godbolt.org/z/sPjY1K>`__):
+
+ .. code:: c++
+
+ #include <fmt/core.h>
+
+ int main() {
+ char buffer[10];
+ auto result = fmt::format_to_n(buffer, sizeof(buffer), "{}", 42);
+ }
+
+* Added ``fmt::format_to_n`` overload with format string compilation
+ (`#1764 <https://github.com/fmtlib/fmt/issues/1764>`_,
+ `#1767 <https://github.com/fmtlib/fmt/pull/1767>`_,
+ `#1869 <https://github.com/fmtlib/fmt/pull/1869>`_). For example
+ (`godbolt <https://godbolt.org/z/93h86q>`__):
+
+ .. code:: c++
+
+ #include <fmt/compile.h>
+
+ int main() {
+ char buffer[8];
+ fmt::format_to_n(buffer, sizeof(buffer), FMT_COMPILE("{}"), 42);
+ }
+
+ Thanks `@Kurkin (Dmitry Kurkin) <https://github.com/Kurkin>`_,
+ `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
+
+* Added ``fmt::format_to`` overload that take ``text_style``
+ (`#1593 <https://github.com/fmtlib/fmt/issues/1593>`_,
+ `#1842 <https://github.com/fmtlib/fmt/issues/1842>`_,
+ `#1843 <https://github.com/fmtlib/fmt/pull/1843>`_). For example
+ (`godbolt <https://godbolt.org/z/91153r>`__):
+
+ .. code:: c++
+
+ #include <fmt/color.h>
+
+ int main() {
+ std::string out;
+ fmt::format_to(std::back_inserter(out),
+ fmt::emphasis::bold | fg(fmt::color::red),
+ "The answer is {}.", 42);
+ }
+
+ Thanks `@Naios (Denis Blank) <https://github.com/Naios>`_.
+
+* Made the ``'#'`` specifier emit trailing zeros in addition to the decimal
+ point (`#1797 <https://github.com/fmtlib/fmt/issues/1797>`_). For example
+ (`godbolt <https://godbolt.org/z/bhdcW9>`__):
+
+ .. code:: c++
+
+ #include <fmt/core.h>
+
+ int main() {
+ fmt::print("{:#.2g}", 0.5);
+ }
+
+ prints ``0.50``.
+
+* Changed the default floating point format to not include ``.0`` for
+ consistency with ``std::format`` and ``std::to_chars``
+ (`#1893 <https://github.com/fmtlib/fmt/issues/1893>`_,
+ `#1943 <https://github.com/fmtlib/fmt/issues/1943>`_). 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`` (`#1873 <https://github.com/fmtlib/fmt/issues/1873>`_,
+ `#1917 <https://github.com/fmtlib/fmt/issues/1917>`_).
+
+* Made ``fmt::to_string`` fallback on ``ostream`` insertion operator if
+ the ``formatter`` specialization is not provided
+ (`#1815 <https://github.com/fmtlib/fmt/issues/1815>`_,
+ `#1829 <https://github.com/fmtlib/fmt/pull/1829>`_).
+ Thanks `@alexezeder (Alexey Ochapov) <https://github.com/alexezeder>`_.
+
+* Added support for the append mode to the experimental file API and
+ improved ``fcntl.h`` detection.
+ (`#1847 <https://github.com/fmtlib/fmt/pull/1847>`_,
+ `#1848 <https://github.com/fmtlib/fmt/pull/1848>`_).
+ Thanks `@t-wiser <https://github.com/t-wiser>`_.
+
+* Fixed handling of types that have both an implicit conversion operator and
+ an overloaded ``ostream`` insertion operator
+ (`#1766 <https://github.com/fmtlib/fmt/issues/1766>`_).
+
+* Fixed a slicing issue in an internal iterator type
+ (`#1822 <https://github.com/fmtlib/fmt/pull/1822>`_).
+ Thanks `@BRevzin (Barry Revzin) <https://github.com/BRevzin>`_.
+
+* Fixed an issue in locale-specific integer formatting
+ (`#1927 <https://github.com/fmtlib/fmt/issues/1927>`_).
+
+* Fixed handling of exotic code unit types
+ (`#1870 <https://github.com/fmtlib/fmt/issues/1870>`_,
+ `#1932 <https://github.com/fmtlib/fmt/issues/1932>`_).
+
+* Improved ``FMT_ALWAYS_INLINE``
+ (`#1878 <https://github.com/fmtlib/fmt/pull/1878>`_).
+ Thanks `@jk-jeon (Junekey Jeon) <https://github.com/jk-jeon>`_.
+
+* Removed dependency on ``windows.h``
+ (`#1900 <https://github.com/fmtlib/fmt/pull/1900>`_).
+ Thanks `@bernd5 (Bernd Baumanns) <https://github.com/bernd5>`_.
+
+* Optimized counting of decimal digits on MSVC
+ (`#1890 <https://github.com/fmtlib/fmt/pull/1890>`_).
+ Thanks `@mwinterb <https://github.com/mwinterb>`_.
+
+* Improved documentation
+ (`#1772 <https://github.com/fmtlib/fmt/issues/1772>`_,

+7.0.3 - 2020-08-06
+------------------
+
+* Worked around broken ``numeric_limits`` for 128-bit integers
+ (`#1787 <https://github.com/fmtlib/fmt/issues/1787>`_).
+
+* Added error reporting on missing named arguments
+ (`#1796 <https://github.com/fmtlib/fmt/issues/1796>`_).
+
+* Stopped using 128-bit integers with clang-cl
+ (`#1800 <https://github.com/fmtlib/fmt/pull/1800>`_).
+ Thanks `@Kingcom <https://github.com/Kingcom>`_.
+
+* Fixed issues in locale-specific integer formatting
+ (`#1782 <https://github.com/fmtlib/fmt/issues/1782>`_,
+ `#1801 <https://github.com/fmtlib/fmt/issues/1801>`_).
+
+7.0.2 - 2020-07-29
+------------------
+
+* Worked around broken ``numeric_limits`` for 128-bit integers
+ (`#1725 <https://github.com/fmtlib/fmt/issues/1725>`_).
+
+* Fixed compatibility with CMake 3.4
+ (`#1779 <https://github.com/fmtlib/fmt/issues/1779>`_).
+
+* Fixed handling of digit separators in locale-specific formatting
+ (`#1782 <https://github.com/fmtlib/fmt/issues/1782>`_).
+
+7.0.1 - 2020-07-07
+------------------
+
+* Updated the inline version namespace name.
+
+* Worked around a gcc bug in mangling of alias templates
+ (`#1753 <https://github.com/fmtlib/fmt/issues/1753>`_).
+
+* Fixed a linkage error on Windows
+ (`#1757 <https://github.com/fmtlib/fmt/issues/1757>`_).
+ Thanks `@Kurkin (Dmitry Kurkin) <https://github.com/Kurkin>`_.
+
+* Fixed minor issues with the documentation.
+
+7.0.0 - 2020-07-05
+------------------
+
+* Reduced the library size. For example, on macOS a stripped test binary
+ statically linked with {fmt} `shrank from ~368k to less than 100k
+ <http://www.zverovich.net/2020/05/21/reducing-library-size.html>`_.
+
+* Added a simpler and more efficient `format string compilation API
+ <https://fmt.dev/7.0.0/api.html#compile-api>`_:
+
+ .. code:: c++
+
+ #include <fmt/compile.h>
+
+ // Converts 42 into std::string using the most efficient method and no
+ // runtime format string processing.
+ std::string s = fmt::format(FMT_COMPILE("{}"), 42);
+
+ The old ``fmt::compile`` API is now deprecated.
+
+* Optimized integer formatting: ``format_to`` with format string compilation
+ and a stack-allocated buffer is now `faster than to_chars on both
+ libc++ and libstdc++
+ <http://www.zverovich.net/2020/06/13/fast-int-to-string-revisited.html>`_.
+
+* Optimized handling of small format strings. For example,
+
+ .. code:: c++
+
+ fmt::format("Result: {}: ({},{},{},{})", str1, str2, str3, str4, str5)
+
+ is now ~40% faster (`#1685 <https://github.com/fmtlib/fmt/issues/1685>`_).
+
+* Applied extern templates to improve compile times when using the core API
+ and ``fmt/format.h`` (`#1452 <https://github.com/fmtlib/fmt/issues/1452>`_).
+ For example, on macOS with clang the compile time of a test translation unit
+ dropped from 2.3s to 0.3s with ``-O2`` and from 0.6s to 0.3s with the default
+ settings (``-O0``).
+
+ Before (``-O2``)::
+
+ % time c++ -c test.cc -I include -std=c++17 -O2
+ c++ -c test.cc -I include -std=c++17 -O2 2.22s user 0.08s system 99% cpu 2.311 total
+
+ After (``-O2``)::
+
+ % time c++ -c test.cc -I include -std=c++17 -O2
+ c++ -c test.cc -I include -std=c++17 -O2 0.26s user 0.04s system 98% cpu 0.303 total
+
+ Before (default)::
+
+ % time c++ -c test.cc -I include -std=c++17
+ c++ -c test.cc -I include -std=c++17 0.53s user 0.06s system 98% cpu 0.601 total
+
+ After (default)::
+
+ % time c++ -c test.cc -I include -std=c++17
+ c++ -c test.cc -I include -std=c++17 0.24s user 0.06s system 98% cpu 0.301 total
+
+ It is still recommended to use ``fmt/core.h`` instead of ``fmt/format.h`` but
+ the compile time difference is now smaller. Thanks
+ `@alex3d <https://github.com/alex3d>`_ for the suggestion.
+
+* Named arguments are now stored on stack (no dynamic memory allocations) and
+ the compiled code is more compact and efficient. For example
+
+ .. code:: c++
+
+ #include <fmt/core.h>
+
+ int main() {
+ fmt::print("The answer is {answer}\n", fmt::arg("answer", 42));
+ }
+
+ compiles to just (`godbolt <https://godbolt.org/z/NcfEp_>`__)
+
+ .. code:: asm
+
+ .LC0:
+ .string "answer"
+ .LC1:
+ .string "The answer is {answer}\n"
+ main:
+ sub rsp, 56
+ mov edi, OFFSET FLAT:.LC1
+ mov esi, 23
+ movabs rdx, 4611686018427387905
+ lea rax, [rsp+32]
+ lea rcx, [rsp+16]
+ mov QWORD PTR [rsp+8], 1
+ mov QWORD PTR [rsp], rax
+ mov DWORD PTR [rsp+16], 42
+ mov QWORD PTR [rsp+32], OFFSET FLAT:.LC0
+ mov DWORD PTR [rsp+40], 0
+ call fmt::v6::vprint(fmt::v6::basic_string_view<char>,
+ fmt::v6::format_args)
+ xor eax, eax
+ add rsp, 56
+ ret
+
+ .L.str.1:
+ .asciz "answer"
+
+* Implemented compile-time checks for dynamic width and precision
+ (`#1614 <https://github.com/fmtlib/fmt/issues/1614>`_):
+
+ .. code:: c++
+
+ #include <fmt/format.h>
+
+ int main() {
+ fmt::print(FMT_STRING("{0:{1}}"), 42);
+ }
+
+ now gives a compilation error because argument 1 doesn't exist::
+
+ In file included from test.cc:1:
+ include/fmt/format.h:2726:27: error: constexpr variable 'invalid_format' must be
+ initialized by a constant expression
+ FMT_CONSTEXPR_DECL bool invalid_format =
+ ^
+ ...
+ include/fmt/core.h:569:26: note: in call to
+ '&checker(s, {}).context_->on_error(&"argument not found"[0])'
+ if (id >= num_args_) on_error("argument not found");
+ ^
+
+* Added sentinel support to ``fmt::join``
+ (`#1689 <https://github.com/fmtlib/fmt/pull/1689>`_)
+
+ .. code:: c++
+
+ struct zstring_sentinel {};
+ bool operator==(const char* p, zstring_sentinel) { return *p == '\0'; }
+ bool operator!=(const char* p, zstring_sentinel) { return *p != '\0'; }
+
+ struct zstring {
+ const char* p;
+ const char* begin() const { return p; }
+ zstring_sentinel end() const { return {}; }
+ };
+
+ auto s = fmt::format("{}", fmt::join(zstring{"hello"}, "_"));
+ // s == "h_e_l_l_o"
+
+ Thanks `@BRevzin (Barry Revzin) <https://github.com/BRevzin>`_.
+
+* Added support for named arguments, ``clear`` and ``reserve`` to
+ ``dynamic_format_arg_store``
+ (`#1655 <https://github.com/fmtlib/fmt/issues/1655>`_,
+ `#1663 <https://github.com/fmtlib/fmt/pull/1663>`_,
+ `#1674 <https://github.com/fmtlib/fmt/pull/1674>`_,
+ `#1677 <https://github.com/fmtlib/fmt/pull/1677>`_).
+ Thanks `@vsolontsov-ll (Vladimir Solontsov)
+ <https://github.com/vsolontsov-ll>`_.
+
+* Added support for the ``'c'`` format specifier to integral types for
+ compatibility with ``std::format``
+ (`#1652 <https://github.com/fmtlib/fmt/issues/1652>`_).
+
+* Replaced the ``'n'`` format specifier with ``'L'`` for compatibility with
+ ``std::format`` (`#1624 <https://github.com/fmtlib/fmt/issues/1624>`_).
+ The ``'n'`` specifier can be enabled via the ``FMT_DEPRECATED_N_SPECIFIER``
+ macro.
+
+* The ``'='`` format specifier is now disabled by default for compatibility with
+ ``std::format``. It can be enabled via the ``FMT_DEPRECATED_NUMERIC_ALIGN``
+ macro.
+
+* Removed the following deprecated APIs:
+
+ * ``FMT_STRING_ALIAS`` and ``fmt`` macros - replaced by ``FMT_STRING``
+ * ``fmt::basic_string_view::char_type`` - replaced by
+ ``fmt::basic_string_view::value_type``
+ * ``convert_to_int``
+ * ``format_arg_store::types``
+ * ``*parse_context`` - replaced by ``*format_parse_context``
+ * ``FMT_DEPRECATED_INCLUDE_OS``
+ * ``FMT_DEPRECATED_PERCENT`` - incompatible with ``std::format``
+ * ``*writer`` - replaced by compiled format API
+
+* Renamed the ``internal`` namespace to ``detail``
+ (`#1538 <https://github.com/fmtlib/fmt/issues/1538>`_). The former is still
+ provided as an alias if the ``FMT_USE_INTERNAL`` macro is defined.
+
+* Improved compatibility between ``fmt::printf`` with the standard specs
+ (`#1595 <https://github.com/fmtlib/fmt/issues/1595>`_,
+ `#1682 <https://github.com/fmtlib/fmt/pull/1682>`_,

+ `#1699 <https://github.com/fmtlib/fmt/pull/1699>`_).
+ Thanks `@rimathia <https://github.com/rimathia>`_.
+
+* Fixed handling of ``operator<<`` overloads that use ``copyfmt``
+ (`#1666 <https://github.com/fmtlib/fmt/issues/1666>`_).
+
+* Added the ``FMT_OS`` CMake option to control inclusion of OS-specific APIs
+ in the fmt target. This can be useful for embedded platforms
+ (`#1654 <https://github.com/fmtlib/fmt/issues/1654>`_,
+ `#1656 <https://github.com/fmtlib/fmt/pull/1656>`_).
+ Thanks `@kwesolowski (Krzysztof Wesolowski)
+ <https://github.com/kwesolowski>`_.
+
+* Replaced ``FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION`` with the ``FMT_FUZZ``
+ macro to prevent interferring with fuzzing of projects using {fmt}
+ (`#1650 <https://github.com/fmtlib/fmt/pull/1650>`_).
+ Thanks `@asraa (Asra Ali) <https://github.com/asraa>`_.
+
+* Fixed compatibility with emscripten
+ (`#1636 <https://github.com/fmtlib/fmt/issues/1636>`_,

It moves the cost of parsing a format string outside of the format function
which can be beneficial when identically formatting many objects of the same
types. Thanks `@stryku (Mateusz Janek) <https://github.com/stryku>`_.
