  Hello All,

  🚀 I'm happy to announce the second release of metajson, the json de/serializer I've been playing with for few weeks.

  It includes:

  • 👌 Support of standard types: std::variant, std::optional and std::tuple
  • ⚡️ Generation of error messages, optimized for low overhead.
  • A benchmark on a large json file canada.json, taken from https://github.com/miloyip/nativejson-benchmark
  • 🛠 Few bug fixes

  👀 From the benchmarks, the library seems to deserialize small objects faster than other libraries, and large objects ~10% slower than rapidjson. See some numbers below.

  🚀 The plan for the future is to deliver monthly releases as long as you or I find potential improvements. Feel free to push features requests or issues.

• v0.1 Changes

  June 05, 2017

  🚀 This is the first release of the library. All the features are completed and the code have been optimized to beat the rapidjson library, #1 on the miloyip's benchmark https://github.com/miloyip/nativejson-benchmark.

  I also made a script to generate a single header version, easier to install:
