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
}
Thanks `@marksantaniello (Mark Santaniello)
<https://github.com/marksantaniello>`_.
* Fixed handling of invalid UTF-8
(`#3038 <https://github.com/fmtlib/fmt/pull/3038>`_,
`#3044 <https://github.com/fmtlib/fmt/pull/3044>`_,
`#3056 <https://github.com/fmtlib/fmt/pull/3056>`_).
Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_ and
`@skeeto (Christopher Wellons) <https://github.com/skeeto>`_.
* Improved Unicode support in ``ostream`` overloads of ``print``
(`#2994 <https://github.com/fmtlib/fmt/pull/2994>`_,
`#3001 <https://github.com/fmtlib/fmt/pull/3001>`_,
`#3025 <https://github.com/fmtlib/fmt/pull/3025>`_).
Thanks `@dimztimz (Dimitrij Mijoski) <https://github.com/dimztimz>`_.
* Fixed handling of the sign specifier in localized formatting on systems with
32-bit ``wchar_t`` (`#3041 <https://github.com/fmtlib/fmt/issues/3041>`_).
* Added support for wide streams to ``fmt::streamed``
(`#2994 <https://github.com/fmtlib/fmt/pull/2994>`_).
Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_.
* Added the ``n`` specifier that disables the output of delimiters when
formatting ranges (`#2981 <https://github.com/fmtlib/fmt/pull/2981>`_,
`#2983 <https://github.com/fmtlib/fmt/pull/2983>`_).
For example (`godbolt <https://godbolt.org/z/roKqGdj8c>`__):
.. code:: c++
#include <fmt/ranges.h>
#include <vector>
int main() {
auto v = std::vector{1, 2, 3};
fmt::print("{:n}\n", v); // prints 1, 2, 3
}
Thanks `@BRevzin (Barry Revzin) <https://github.com/BRevzin>`_.
* Worked around problematic ``std::string_view`` constructors introduced in
C++23 (`#3030 <https://github.com/fmtlib/fmt/issues/3030>`_,
`#3050 <https://github.com/fmtlib/fmt/issues/3050>`_).
Thanks `@strega-nil-ms (nicole mazzuca) <https://github.com/strega-nil-ms>`_.
* Improve handling (exclusion) of recursive ranges
(`#2968 <https://github.com/fmtlib/fmt/issues/2968>`_,
`#2974 <https://github.com/fmtlib/fmt/pull/2974>`_).
Thanks `@Dani-Hub (Daniel Krügler) <https://github.com/Dani-Hub>`_.
* Improved error reporting in format string compilation
(`#3055 <https://github.com/fmtlib/fmt/issues/3055>`_).
* Improved the implementation of
`Dragonbox <https://github.com/jk-jeon/dragonbox>`_, the algorithm used for
the default floating-point formatting
(`#2984 <https://github.com/fmtlib/fmt/pull/2984>`_).
Thanks `@jk-jeon (Junekey Jeon) <https://github.com/jk-jeon>`_.
* Fixed issues with floating-point formatting on exotic platforms.
* Improved the implementation of chrono formatting
(`#3010 <https://github.com/fmtlib/fmt/pull/3010>`_).
Thanks `@phprus (Vladislav Shchapov) <https://github.com/phprus>`_.
* Improved documentation
(`#2966 <https://github.com/fmtlib/fmt/pull/2966>`_,
`#3009 <https://github.com/fmtlib/fmt/pull/3009>`_,
`#3020 <https://github.com/fmtlib/fmt/issues/3020>`_,
`#3037 <https://github.com/fmtlib/fmt/pull/3037>`_).
Thanks `@mwinterb <https://github.com/mwinterb>`_,
`@jcelerier (Jean-Michaël Celerier) <https://github.com/jcelerier>`_
and `@remiburtin (Rémi Burtin) <https://github.com/remiburtin>`_.
* Improved build configuration
(`#2991 <https://github.com/fmtlib/fmt/pull/2991>`_,
`#2995 <https://github.com/fmtlib/fmt/pull/2995>`_,
`#3004 <https://github.com/fmtlib/fmt/issues/3004>`_,
`#3007 <https://github.com/fmtlib/fmt/pull/3007>`_,
`#3040 <https://github.com/fmtlib/fmt/pull/3040>`_).
Thanks `@dimztimz (Dimitrij Mijoski) <https://github.com/dimztimz>`_ and
`@hwhsu1231 (Haowei Hsu) <https://github.com/hwhsu1231>`_.
* Fixed various warnings and compilation issues

`#2971 <https://github.com/fmtlib/fmt/pull/2971>`_,
`#2975 <https://github.com/fmtlib/fmt/issues/2975>`_,
