- 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.
