12.0.0
- Optimized the default floating point formatting
(https://github.com/fmtlib/fmt/issues/3675,
https://github.com/fmtlib/fmt/issues/4516). In particular, formatting a
`double` with format string compilation into a stack allocated buffer is
more than 60% faster in version 12.0 compared to 11.2 according to
[dtoa-benchmark](https://github.com/fmtlib/dtoa-benchmark):
```
Function Time (ns) Speedup
fmt11 34.471 1.00x
fmt12 21.000 1.64x
```

449abf73b31b" />
- Added `constexpr` support to `fmt::format`. For example:
```c++
#include <fmt/compile.h>
using namespace fmt::literals;
std::string s = fmt::format(""_cf, 42);
```
now works at compile time provided that `std::string` supports `constexpr`
(https://github.com/fmtlib/fmt/issues/3403,
https://github.com/fmtlib/fmt/pull/4456). Thanks @msvetkin.
- Added `FMT_STATIC_FORMAT` that allows formatting into a string of the exact
required size at compile time.
For example:
```c++
#include <fmt/compile.h>
constexpr auto s = FMT_STATIC_FORMAT("{}", 42);
```
compiles to just
```s
__ZL1s:
.asciiz "42"
```
It can be accessed as a C string with `s.c_str()` or as a string view with
`s.str()`.
- Improved C++20 module support
(https://github.com/fmtlib/fmt/pull/4451,
https://github.com/fmtlib/fmt/pull/4459,
https://github.com/fmtlib/fmt/pull/4476,
https://github.com/fmtlib/fmt/pull/4488,
https://github.com/fmtlib/fmt/issues/4491,
https://github.com/fmtlib/fmt/pull/4495).
Thanks @arBmind, @tkhyn, @Mishura4, @anonymouspc and @autoantwort.
- Switched to using estimated display width in precision. For example:
```c++
fmt::print("|{:.4}|\n|1234|\n", "🐱🐱🐱");
```
prints

because `🐱` has an estimated width of 2
(https://github.com/fmtlib/fmt/issues/4272,
https://github.com/fmtlib/fmt/pull/4443,
https://github.com/fmtlib/fmt/pull/4475).
Thanks @nikhilreddydev and @localspook.
- Fix interaction between debug presentation, precision, and width for strings
(https://github.com/fmtlib/fmt/pull/4478). Thanks @localspook.
- Implemented allocator propagation on `basic_memory_buffer` move
(https://github.com/fmtlib/fmt/issues/4487,
https://github.com/fmtlib/fmt/pull/4490). Thanks @toprakmurat.
- Fixed an ambiguity between `std::reference_wrapper<T>` and `format_as`
formatters (https://github.com/fmtlib/fmt/issues/4424,
https://github.com/fmtlib/fmt/pull/4434). Thanks @jeremy-rifkin.
- Removed the following deprecated APIs:
- `has_formatter`: use `is_formattable` instead,
- `basic_format_args::parse_context_type`,
`basic_format_args::formatter_type` and similar aliases in context types,
- wide stream overload of `fmt::printf`,
- wide stream overloads of `fmt::print` that take text styles,
- `is_*char` traits,
- `fmt::localtime`.
- Deprecated wide overloads of `fmt::fprintf` and `fmt::sprintf`.
- Improved diagnostics for the incorrect usage of `fmt::ptr`
(https://github.com/fmtlib/fmt/pull/4453). Thanks @TobiSchluter.
- Made handling of ANSI escape sequences more efficient
(https://github.com/fmtlib/fmt/pull/4511,
https://github.com/fmtlib/fmt/pull/4528).
Thanks @localspook and @Anas-Hamdane.

(https://github.com/fmtlib/fmt/pull/4498). Thanks @dominicpoeschko.
- Fixed an integer overflow for precision close to the max `int` value.
- Fixed compatibility with WASI (https://github.com/fmtlib/fmt/issues/4496,
https://github.com/fmtlib/fmt/pull/4497). Thanks @whitequark.
- Fixed `back_insert_iterator` detection, preventing a fallback on slower path
that handles arbitrary iterators (https://github.com/fmtlib/fmt/issues/4454).
- Fixed handling of invalid glibc `FILE` buffers
(https://github.com/fmtlib/fmt/issues/4469).
- Added `wchar_t` support to the `std::byte` formatter
(https://github.com/fmtlib/fmt/issues/4479,
https://github.com/fmtlib/fmt/pull/4480). Thanks @phprus.
- Changed component prefix from `fmt-` to `fmt_` for compatibility with
NSIS/CPack on Windows, e.g. `fmt-doc` changed to `fmt_doc`
(https://github.com/fmtlib/fmt/issues/4441,
https://github.com/fmtlib/fmt/pull/4442). Thanks @n-stein.
- Added the `FMT_CUSTOM_ASSERT_FAIL` macro to simplify providing a custom
`fmt::assert_fail` implementation (https://github.com/fmtlib/fmt/pull/4505).
Thanks @HazardyKnusperkeks.
- Switched to `FMT_THROW` on reporting format errors so that it can be
overriden by users when exceptions are disabled
(https://github.com/fmtlib/fmt/pull/4521). Thanks @HazardyKnusperkeks.
- Improved master project detection and disabled install targets when using
{fmt} as a subproject by default (https://github.com/fmtlib/fmt/pull/4536).
Thanks @crueter.
