Defining JSON_DELETE_DEPRECATED_FUNCTIONS to 1 (or the CMake option JSON_DeleteDeprecatedFunctions) declares every deprecated function as deleted instead of deprecated, so that code that is not ready for 4.0.0 no longer compiles. A deleted function still takes part in overload resolution, so from_*(ptr, len) cannot silently bind len to the strict parameter of from_*(InputType&&, bool); the roadmap now plans to keep these overloads deleted in 4.0.0 instead of removing them. The legacy discarded-value comparison is left to its own macro. Also update the 4.0 roadmap: add JSON_DISABLE_TUPLE_REFERENCE_CONVERSION and JSON_DELETE_DEPRECATED_FUNCTIONS to the macro table, add the from_bjdata/from_bon8 (ptr, len) overloads to the deprecated functions, document the macro in the migration guide, and fix the docs style check findings (example titles, missing docset entry for JSON_STRICT_BINARY_UTF8).

This URL provides the most recent documentation and also applies to previous versions. Documentation for deprecated
functions is not removed; instead, it is marked as deprecated.

using tag v3.10.2):
git clone https://github.com/nlohmann/json.git
cd json
git checkout v3.10.2
make install_venv serve -C docs/mkdocs
