+* Added ``FMT_VERSION`` macro (`#411 <https://github.com/fmtlib/fmt/issues/411>`_).
 
-  .. code:: c++
+* Used ``FMT_NULL`` instead of literal ``0`` (`#409 <https://github.com/fmtlib/fmt/pull/409>`_). Thanks `@alabuzhev (Alex Alabuzhev) <https://github.com/alabuzhev>`_.
 
-     #define FMT_EXTENDED_COLORS
-     #define FMT_HEADER_ONLY // or compile fmt with FMT_EXTENDED_COLORS defined
-     #include <fmt/format.h>
+* Added extern templates for ``format_float`` (`#413 <https://github.com/fmtlib/fmt/issues/413>`_).
 
-     fmt::print(fmt::color::steel_blue, "Some beautiful text");
-
-  The old API (the ``print_colored`` and ``vprint_colored`` functions and the
-  ``color`` enum) is now deprecated.
-  (`#762 <https://github.com/fmtlib/fmt/issues/762>`_

-  (`#766 <https://github.com/fmtlib/fmt/pull/766>`_).
-  Thanks `@Remotion (Remo) <https://github.com/Remotion>`_.
-
-* Made ``format_to`` work with ``basic_memory_buffer``
-  (`#776 <https://github.com/fmtlib/fmt/issues/776>`_).
-
-* Added ``vformat_to_n`` and ``wchar_t`` overload of ``format_to_n``
-  (`#764 <https://github.com/fmtlib/fmt/issues/764>`_,
-  `#769 <https://github.com/fmtlib/fmt/issues/769>`_).
-

-5.0.0 - 2018-05-21
-------------------
-
-* Added a requirement for partial C++11 support, most importantly variadic
-  templates and type traits, and dropped ``FMT_VARIADIC_*`` emulation macros.
-  Variadic templates are available since GCC 4.4, Clang 2.9 and MSVC 18.0 (2013).
-  For older compilers use {fmt} `version 4.x
-  <https://github.com/fmtlib/fmt/releases/tag/4.1.0>`_ which continues to be
-  maintained and works with C++98 compilers.
-
-* Renamed symbols to follow standard C++ naming conventions and proposed a subset
-  of the library for standardization in `P0645R2 Text Formatting
-  <https://wg21.link/P0645>`_.
-
-* Implemented ``constexpr`` parsing of format strings and `compile-time format
-  string checks
-  <http://fmtlib.net/dev/api.html#compile-time-format-string-checks>`_. For
-  example
-
-  .. code:: c++
-
-     #include <fmt/format.h>
-
-     std::string s = format(fmt("{:d}"), "foo");
-
-  gives a compile-time error because ``d`` is an invalid specifier for strings

-
-  Compile-time checks require relaxed ``constexpr`` (C++14 feature) support. If
-  the latter is not available, checks will be performed at runtime.
-
-* Separated format string parsing and formatting in the extension API to enable
-  compile-time format string processing. For example
-
-  .. code:: c++
-
-     struct Answer {};
-
-     namespace fmt {
-     template <>
-     struct formatter<Answer> {
-       constexpr auto parse(parse_context& ctx) {

-           format_to(ctx.begin(), "{}", "fourty-two") :
-           format_to(ctx.begin(), "{}", 42);
-       }
-
-       char spec = 0;
-     };
-     }
-
-     std::string s = format(fmt("{:x}"), Answer());
-
-  gives a compile-time error due to invalid format specifier (`godbolt

-
-     ...
-     <source>:12:45: error: expression '<throw-expression>' is not a constant expression
-            throw format_error("invalid specifier");
-
-* Added `iterator support
-  <http://fmtlib.net/dev/api.html#output-iterator-support>`_:
-
-  .. code:: c++
-
-     #include <vector>
-     #include <fmt/format.h>
-
-     std::vector<char> out;
-     fmt::format_to(std::back_inserter(out), "{}", 42);
-
-* Added the `format_to_n
-  <http://fmtlib.net/dev/api.html#_CPPv2N3fmt11format_to_nE8OutputItNSt6size_tE11string_viewDpRK4Args>`_
-  function that restricts the output to the specified number of characters
-  (`#298 <https://github.com/fmtlib/fmt/issues/298>`_):
-
-  .. code:: c++
-
-     char out[4];
-     fmt::format_to_n(out, sizeof(out), "{}", 12345);
-     // out == "1234" (without terminating '\0')
-
-* Added the `formatted_size
-  <http://fmtlib.net/dev/api.html#_CPPv2N3fmt14formatted_sizeE11string_viewDpRK4Args>`_
-  function for computing the output size:
-
-  .. code:: c++
-
-     #include <fmt/format.h>
-
-     auto size = fmt::formatted_size("{}", 12345); // size == 5
-
-* Improved compile times by reducing dependencies on standard headers and
-  providing a lightweight `core API <http://fmtlib.net/dev/api.html#core-api>`_:
-
-  .. code:: c++
-
-     #include <fmt/core.h>
-
-     fmt::print("The answer is {}.", 42);
-
-  See `Compile time and code bloat
-  <https://github.com/fmtlib/fmt#compile-time-and-code-bloat>`_.
-
-* Added the `make_format_args
-  <http://fmtlib.net/dev/api.html#_CPPv2N3fmt16make_format_argsEDpRK4Args>`_
-  function for capturing formatting arguments:
-
-  .. code:: c++
-  
-     // Prints formatted error message.
-     void vreport_error(const char *format, fmt::format_args args) {
-       fmt::print("Error: ");
-       fmt::vprint(format, args);
-     }
-     template <typename... Args>
-     void report_error(const char *format, const Args & ... args) {
-       vreport_error(format, fmt::make_format_args(args...));
-     }
-
-* Added the ``make_printf_args`` function for capturing ``printf`` arguments
-  (`#687 <https://github.com/fmtlib/fmt/issues/687>`_,
-  `#694 <https://github.com/fmtlib/fmt/pull/694>`_).
-  Thanks `@Kronuz (Germán Méndez Bravo) <https://github.com/Kronuz>`_.
-
-* Added prefix ``v`` to non-variadic functions taking ``format_args`` to
-  distinguish them from variadic ones:
-
-  .. code:: c++
-
-     std::string vformat(string_view format_str, format_args args);
-     
-     template <typename... Args>
-     std::string format(string_view format_str, const Args & ... args);
-
-* Added experimental support for formatting ranges, containers and tuple-like
-  types in ``fmt/ranges.h`` (`#735 <https://github.com/fmtlib/fmt/pull/735>`_):
-
-  .. code:: c++
-
-     #include <fmt/ranges.h>
-
-     std::vector<int> v = {1, 2, 3};
-     fmt::print("{}", v); // prints {1, 2, 3}
-
-  Thanks `@Remotion (Remo) <https://github.com/Remotion>`_.
-
-* Implemented ``wchar_t`` date and time formatting
-  (`#712 <https://github.com/fmtlib/fmt/pull/712>`_):

-
-* Provided more wide string overloads
-  (`#724 <https://github.com/fmtlib/fmt/pull/724>`_).
-  Thanks `@DanielaE (Daniela Engert) <https://github.com/DanielaE>`_.
-
-* Switched from a custom null-terminated string view class to ``string_view``
-  in the format API and provided ``fmt::string_view`` which implements a subset
-  of ``std::string_view`` API for pre-C++17 systems.
-
-* Added support for ``std::experimental::string_view``
-  (`#607 <https://github.com/fmtlib/fmt/pull/607>`_):
-
-  .. code:: c++
-
-     #include <fmt/core.h>

-
-     fmt::print("{}", std::experimental::string_view("foo"));
-
-  Thanks `@virgiliofornazin (Virgilio Alexandre Fornazin)
-  <https://github.com/virgiliofornazin>`__.

 API Reference
 *************
 
-The {fmt} library API consists of the following parts:
+All functions and classes provided by the fmt library reside
+in namespace ``fmt`` and macros have prefix ``FMT_``. For brevity the
+namespace is usually omitted in examples.
 
-* :ref:`fmt/core.h <core-api>`: the core API providing argument handling
-  facilities and a lightweight subset of formatting functions
-* :ref:`fmt/format.h <format-api>`: the full format API providing compile-time
-  format string checks, output iterator and user-defined type support
-* :ref:`fmt/time.h <time-api>`: date and time formatting
-* :ref:`fmt/ostream.h <ostream-api>`: ``std::ostream`` support
-* :ref:`fmt/printf.h <printf-api>`: ``printf`` formatting
+Format API

-
-Core API
-========
-
-``fmt/core.h`` defines the core API which provides argument handling facilities
-and a lightweight subset of formatting functions.
-
-The following functions use :ref:`format string syntax <syntax>`
-imilar to that of Python's `str.format
-<http://docs.python.org/3/library/stdtypes.html#str.format>`_.
+The following functions defined in ``fmt/format.h`` use :ref:`format string
+syntax <syntax>` similar to the one used by Python's `str.format
+<http://docs.python.org/3/library/stdtypes.html#str.format>`_ function.
 They take *format_str* and *args* as arguments.
 
 *format_str* is a format string that contains literal text and replacement
 fields surrounded by braces ``{}``. The fields are replaced with formatted
 arguments in the resulting string.
 
-*args* is an argument list representing objects to be formatted.
+*args* is an argument list representing arbitrary arguments.
+
+The `performance of the format API
+<https://github.com/fmtlib/fmt/blob/master/README.rst#speed-tests>`_ is close
+to that of glibc's ``printf`` and better than the performance of IOStreams.
+For even better speed use the `write API`_.

-Format API
-==========
-
-``fmt/format.h`` defines the full format API providing compile-time format
-string checks, output iterator and user-defined type support.
-
-Compile-time format string checks
----------------------------------
-
-.. doxygendefine:: fmt
-
-Formatting user-defined types
------------------------------
-
-To make a user-defined type formattable, specialize the ``formatter<T>`` struct
-template and implement ``parse`` and ``format`` methods::
-
-  #include <fmt/format.h>
-
-  struct point { double x, y; };
-
-  namespace fmt {
-  template <>
-  struct formatter<point> {
-    template <typename ParseContext>
-    constexpr auto parse(ParseContext &ctx) { return ctx.begin(); }
-
-    template <typename FormatContext>
-    auto format(const point &p, FormatContext &ctx) {
-      return format_to(ctx.begin(), "({:.1f}, {:.1f})", p.x, p.y);
-    }
-  };
-  }
-
-Then you can pass objects of type ``point`` to any formatting function::
-
-  point p = {1, 2};
-  std::string s = fmt::format("{}", p);
-  // s == "(1.0, 2.0)"
-
-In the example above the ``formatter<point>::parse`` function ignores the
-contents of the format string referred to by ``ctx.begin()`` so the object will
-always be formatted in the same way. See ``formatter<tm>::parse`` in
-:file:`fmt/time.h` for an advanced example of how to parse the format string and
-customize the formatted output.
-
-This section shows how to define a custom format function for a user-defined
-type. The next section describes how to get ``fmt`` to use a conventional stream
-output ``operator<<`` when one is defined for a user-defined type.

-Custom allocators
------------------
-
-The {fmt} library supports custom dynamic memory allocators.
-A custom allocator class can be specified as a template argument to

-
-    using custom_memory_buffer = 
-      fmt::basic_memory_buffer<char, fmt::inline_buffer_size, custom_allocator>;
-
-It is also possible to write a formatting function that uses a custom
-allocator::
-
-    using custom_string =
-      std::basic_string<char, std::char_traits<char>, custom_allocator>;
-
-    custom_string vformat(custom_allocator alloc, fmt::string_view format_str,
-                          fmt::format_args args) {
-      custom_memory_buffer buf(alloc);
-      fmt::vformat_to(buf, format_str, args);
-      return custom_string(buf.data(), buf.size(), alloc);
-    }
-
-    template <typename ...Args>
-    inline custom_string format(custom_allocator alloc,

+Write API
+=========
+
+The write API provides classes for writing formatted data into character
+streams. It is usually faster than the `format API`_ but, as IOStreams,
+may result in larger compiled code size. The main writer class is
+`~fmt::BasicMemoryWriter` which stores its output in a memory buffer and provides
+direct access to it. It is possible to create custom writers that
+store output elsewhere by subclassing `~fmt::BasicWriter`.

+
+    CustomString format(CustomAllocator alloc, fmt::CStringRef format_str,

+The library is highly portable. Here is an incomplete list of operating systems and
+compilers where it has been tested and known to work:
 
-* variadic templates
-* type traits
-* rvalue references
-* decltype
-* trailing return types
-* deleted functions
+* 64-bit (amd64) GNU/Linux with GCC 4.4.3, `4.6.3 <https://travis-ci.org/fmtlib/fmt>`_,
+  4.7.2, 4.8.1 and Intel C++ Compiler (ICC) 14.0.2
 
-These are available since GCC 4.4, Clang 2.9 and MSVC 18.0 (2013). For older
-compilers use fmt `version 4.x
-<https://github.com/fmtlib/fmt/releases/tag/4.1.0>`_ which continues to be
-maintained and only requires C++98.
+* 32-bit (i386) GNU/Linux with GCC 4.4.3, 4.6.3
 
-The output of all formatting functions is consistent across platforms. In
-particular, formatting a floating-point infinity always gives ``inf`` while the
-output of ``printf`` is platform-dependent in this case. For example,
+* Mac OS X with GCC 4.2.1 and Clang 4.2, 5.1.0
+
+* 64-bit Windows with Visual C++ 2010, 2013 and
+  `2015 <https://ci.appveyor.com/project/vitaut/fmt>`_
+
+* 32-bit Windows with Visual C++ 2010
+
+Although the library uses C++11 features when available, it also works with older
+compilers and standard library implementations. The only thing to keep in mind 
+for C++98 portability:
+
+* Variadic templates: minimum GCC 4.4, Clang 2.9 or VS2013. This feature allows 
+  the Format API to accept an unlimited number of arguments. With older compilers
+  the maximum is 15.
+
+* User-defined literals: minimum GCC 4.7, Clang 3.1 or VS2015. The suffixes 
+  ``_format`` and ``_a`` are functionally equivalent to the functions 
+  ``fmt::format`` and ``fmt::arg``.
