Niels Lohmann 8418ff85b6 Document what counts as a breaking change in the API stability rules
Spell out the 3.x compatibility rules in the roadmap: new defaulted
parameters, new default arguments, noexcept/constexpr, template
parameters, parse and dump results, accepted input, key iteration order,
iterator invalidation, implicit conversions, to_json/from_json lookup,
json_sax, value_t enumerators, and documented macros, CMake options and
headers. Also list std::hash values as not part of the public API, and
link the macro overview from the section.

Please note: Please note:
- GCC 4.8 has a bug [57824](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57824): multiline raw strings cannot be the arguments to macros. Don't use multiline raw strings directly in macros with this compiler. - GCC 4.8 has a bug [57824](https://gcc.gnu.org/bugzilla/show_bug.cgi?id=57824): multiline raw strings cannot be the arguments to macros. Don't use multiline raw strings directly in macros with this compiler.
- For GCC running on MinGW or Android, the error `'to_string' is not a member of 'std'` (or similarly, for `strtod` or `strtof`) may occur. Note this is not an issue with the code, but rather with the compiler or C++ standard library itself: use a recent toolchain (for Android, a current [NDK](https://developer.android.com/ndk) with the LLVM C++ library `APP_STL := c++_shared`, and for MinGW, a distribution with a complete C++11 standard library). See [this discussion](https://github.com/nlohmann/json/issues/136) for MinGW and [this discussion](https://github.com/nlohmann/json/issues/219) for the old Android NDK using `APP_STL := gnustl_static`. - Android defaults to using very old compilers and C++ libraries. To fix this, add the following to your `Application.mk`. This will switch to the LLVM C++ library, the Clang compiler, and enable C++11 and other features disabled by default.
```makefile
APP_STL := c++_shared
NDK_TOOLCHAIN_VERSION := clang3.6
APP_CPPFLAGS += -frtti -fexceptions
```
The code compiles successfully with [Android NDK](https://developer.android.com/ndk/index.html?hl=ml), Revision 9 - 11 (and possibly later) and [CrystaX's Android NDK](https://www.crystax.net/en/android/ndk) version 10.
- For GCC running on MinGW or Android SDK, the error `'to_string' is not a member of 'std'` (or similarly, for `strtod` or `strtof`) may occur. Note this is not an issue with the code, but rather with the compiler itself. On Android, see above to build with a newer environment. For MinGW, please refer to [this site](https://tehsausage.com/mingw-to-string) and [this discussion](https://github.com/nlohmann/json/issues/136) for information on how to fix this bug. For Android NDK using `APP_STL := gnustl_static`, please refer to [this discussion](https://github.com/nlohmann/json/issues/219).
- Unsupported versions of GCC and Clang are rejected by `#error` directives. This can be switched off by defining `JSON_SKIP_UNSUPPORTED_COMPILER_CHECK`. Note that you can expect no support in this case. - Unsupported versions of GCC and Clang are rejected by `#error` directives.

# JSON_HAS_RANGE_VIEW_CONVERSION
```cpp
#define JSON_HAS_RANGE_VIEW_CONVERSION /* value */
```
This macro indicates whether a JSON array can be constructed directly from a C++20 range view (`std::ranges::view`),
such as the result of `std::views::filter` or `std::views::transform`. Possible values are `1` when supported or `0`
when unsupported.
## Default definition
The default value is `1` if [`JSON_HAS_RANGES`](json_has_ranges.md) is `1` and the compiler is not MinGW (that is,
`#!cpp __MINGW32__` is not defined), and `0` otherwise.
When the macro is not defined, the library will define it to its default value.
!!! info "Known compiler/stdlib exclusions"
- **MinGW** -- disabled, because its `std::ranges` support is incomplete ([issue #4916](https://github.com/nlohmann/json/issues/4916)).
- All toolchains for which [`JSON_HAS_RANGES`](json_has_ranges.md#default-definition) is disabled.
## Examples
??? example
The code below forces the library to disable the conversion from range views:
```cpp
#define JSON_HAS_RANGE_VIEW_CONVERSION 0
#include <nlohmann/json.hpp>
...
```

## `JSON_HAS_RANGES`
The library uses `std::ranges` (and concepts) where available, for example, to parse from C++20 ranges and to
construct JSON arrays from range views. The library detects whether the standard library supports ranges and
disables the support on toolchains with an incomplete implementation. To override the built-in check, define
`JSON_HAS_RANGES` to `1` or `0`.
See [full documentation of `JSON_HAS_RANGES`](../api/macros/json_has_ranges.md).
## `JSON_HAS_RANGE_VIEW_CONVERSION`
When `JSON_HAS_RANGES` is enabled (and the compiler is not MinGW), a JSON array can be constructed directly from a C++20
range view such as `std::views::filter(...)`. To override the built-in check, define `JSON_HAS_RANGE_VIEW_CONVERSION` to
`1` or `0`.
See [full documentation of `JSON_HAS_RANGE_VIEW_CONVERSION`](../api/macros/json_has_range_view_conversion.md).
## `JSON_HAS_STATIC_RTTI`
The library detects whether the compiler supports run time type information (RTTI), which it needs, for instance, to
exclude `std::any` from the candidate types of the implicit conversion on C++17. To override the built-in check, define
`JSON_HAS_STATIC_RTTI` to `1` or `0`.
See [full documentation of `JSON_HAS_STATIC_RTTI`](../api/macros/json_has_static_rtti.md).
## `JSON_HAS_STD_FORMAT`
When compiling with C++20 and a standard library that provides `<format>`, the library provides a `std::formatter`
specialization for JSON values. To override the built-in check, define `JSON_HAS_STD_FORMAT` to `1` or `0`.
See [full documentation of `JSON_HAS_STD_FORMAT`](../api/macros/json_has_std_format.md).
## `JSON_HAS_THREE_WAY_COMPARISON`
When the compiler and standard library support 3-way comparison (the spaceship operator `<=>`), the library provides it
for JSON values. To override the built-in check, define `JSON_HAS_THREE_WAY_COMPARISON` to `1` or `0`.
See [full documentation of `JSON_HAS_THREE_WAY_COMPARISON`](../api/macros/json_has_three_way_comparison.md).
## `JSON_NOEXCEPTION` ## `JSON_NOEXCEPTION`
Exceptions can be switched off by defining the symbol `JSON_NOEXCEPTION`. Exceptions can be switched off by defining the symbol `JSON_NOEXCEPTION`.
