Summary

Version 3.11.0 moved the user-defined string literals (UDL) into namespace nlohmann::literals::json_literals (see documentation). Unfortunately, this namespace was not imported to the global namespace by default which broke code. This release fixes this bug.

All changes are backward-compatible. See release notes of version 3.11.0 for more information on other features.

🐛 Bug fixes

• Set default value of JSON_USE_GLOBAL_UDLS and the CMake options JSON_GlobalUDLs to 1 to import the user-defined string literals from the nlohmann::literals::json_literals namespace into the global namespace by default.
  • _json operator""()  #3644
  • Regression: no matching literal operator for call to 'operator""_json' #3645
  • Fix global UDLs #3646
