SemVer ABI break in detail headers from v3.7.3 and v3.10.5

[Ryanf55]

Between Ubuntu 20, and Ubuntu 22, I am facing compile errors with due to changes in the public header.

json/include/nlohmann/detail/exceptions.hpp

Lines 127 to 128 in 4f8fba1

	template<typename BasicJsonType>
	static parse_error create(int id_, const position_t& pos, const std::string& what_arg, const BasicJsonType& context)

https://github.com/nlohmann/json/blob/v3.7.3/include/nlohmann/detail/exceptions.hpp#L129

Is it intended that all the public headerfiles be SemVer compliant, or is the detail namespace excluded?

We only used the nlohmann/json.hpp as the include.

Relates to #3473 (comment).

Are you using something in the detail namespace directly?

[Ryanf55]

Yes. The above function call to create(...)

The detail namespace isn't part of the public API. Use at your own risk. Note, that the create() functions changed again in v3.11.x (context was changed to a pointer argument). (Since you mentioned ABI, there were zero guarantees about ABI compatibility before v3.11.x, i.e., all code sharing objects has to be compiled against the same version of the library.)
