iod.metajson v0.2 Release Notes
Release Date: 2017-06-21 // almost 7 years ago-
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.

🚀 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:
