Performance
- Faster and simpler UTF-8 validation with the lookup4 algorithm #993
- We improved the performance of simdjson under Visual Studio by about 25%. Users will still get better performance with clang-cl (+30%) but the gap has been reduced. #1031
Code usability
- In
parse_many, when parsing streams of JSON documetns, we give to the users runtime control as to whether threads are used (via the parser.threaded attribute). #925 - Prefixed public macros to avoid name clashes with other libraries. #1035
- Better documentation regarding package managers (brew, MSYS2, conan, apt, vcpkg, FreeBSD package manager, etc.).
- Better documentation regarding CMake usage.
Standards
- We improved standard compliance with respect to both the JSON RFC 8259 and JSON Pointer RFC 6901. We added the at_pointer method to nodes for standard-compliant JSON Pointer queries. The legacy
at(std::string_view)method remains but is deprecated since it is not standard-compliant as per RFC 6901. - We removed computed GOTOs without sacrificing performance thus improving the C++ standard compliance (since computed GOTOs are compiler-specific extensions).
- Better support for C++20 #1050
