Version 0.5 outline

[lemire]

Performance

• Faster and simpler UTF-8 validation with the lookup4 algorithm lookup4 (new UTF-8 validation) #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. Make simd8 64 uncopyable and other Visual Studio optimizations #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). Add a parameter to parse_many so that users can request single-threaded execution #925
• Prefixed public macros to avoid name clashes with other libraries. All simdjson macros should be prefixed with SIMDJSON to avoid clashes #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 Add support for C++ 20 ranges. #1050

@jkeiser Regarding the point "Conan / Package Managers" =>

https://github.com/conan-io/conan-center-index/search?q=simdjson&unscoped_q=simdjson

[lemire]

Version 0.2.1 is on conan. I have created a PR to add version 0.4.6, see conan-io/conan-center-index#2104

[lemire]

Version 0.4.7 is in conan. We are also in msys2, vcpckg, debian... there is a freebsd port.

[lemire]

You can now install simdjson via brew.

[lemire]

You can also install simdjson via "apt-get".

@jkeiser I have updated the outline. Have a look if you'd like.

Whichever of these package managers is new, I think it's worth calling out that it's easier than ever to get simdjson. I'd call out what package managers we support and that you can use cmake via fetch. That's awesome work :)

Any new platforms? mingw?

[lemire]

The MSYS2 and brew support came in after 0.4.7, so it is new.

I'll add a note about the better documentation regarding CMake usage.

[lemire]

Released.
