## Introduction
RapidJSON is a JSON parser and generator for C++. It was inspired by [RapidXml](http://rapidxml.sourceforge.net/).
-* RapidJSON is small but complete. It supports both SAX and DOM style API. The SAX parser is only a half thousand lines of code.
+* RapidJSON is **small** but **complete**. It supports both SAX and DOM style API. The SAX parser is only a half thousand lines of code.
-* RapidJSON is fast. Its performance can be comparable to `strlen()`. It also optionally supports SSE2/SSE4.2 for acceleration.

+* RapidJSON is **self-contained** and **header-only**. It does not depend on external libraries such as BOOST. It even does not depend on STL.
-* RapidJSON is memory friendly. Each JSON value occupies exactly 16/20 bytes for most 32/64-bit machines (excluding text string). By default it uses a fast memory allocator, and the parser allocates memory compactly during parsing.

-* RapidJSON is Unicode friendly. It supports UTF-8, UTF-16, UTF-32 (LE & BE), and their detection, validation and transcoding internally. For example, you can read a UTF-8 file and let RapidJSON transcode the JSON strings into UTF-16 in the DOM. It also supports surrogates and "\u0000" (null character).

+
+## Highlights in v1.1 (2016-8-25)
+
+* Added [JSON Pointer](doc/pointer.md)
+* Added [JSON Schema](doc/schema.md)
+* Added [relaxed JSON syntax](doc/dom.md) (comment, trailing comma, NaN/Infinity)
+* Iterating array/object with [C++11 Range-based for loop](doc/tutorial.md)
+* Reduce memory overhead of each `Value` from 24 bytes to 16 bytes in x86-64 architecture.
+
+For other changes please refer to [change log](CHANGELOG.md).
## Compatibility
RapidJSON is a header-only C++ library. Just copy the `include/rapidjson` folder to system or project's include path.
RapidJSON uses following software as its dependencies:
-* [CMake](http://www.cmake.org) as a general build tool
-* (optional)[Doxygen](http://www.doxygen.org) to build documentation
-* (optional)[googletest](https://code.google.com/p/googletest/) for unit and performance testing
+* [CMake](https://cmake.org/) as a general build tool
+* (optional) [Doxygen](http://www.doxygen.org) to build documentation
+* (optional) [googletest](https://github.com/google/googletest) for unit and performance testing
To generate user documentation and run tests please proceed with the steps below:
3. Change to `build` directory and run `cmake ..` command to configure your build. Windows users can do the same with cmake-gui application.
4. On Windows, build the solution found in the build directory. On Linux, run `make` from the build directory.
-On successfull build you will find compiled test and example binaries in `bin`
+On successful build you will find compiled test and example binaries in `bin`
directory. The generated documentation will be available in `doc/html`
directory of the build tree. To run tests after finished build please run `make
test` or `ctest` from your build tree. You can get detailed output using `ctest
-More [examples](https://github.com/miloyip/rapidjson/tree/master/example) are available.

+ * [condense](https://github.com/Tencent/rapidjson/blob/master/example/condense/condense.cpp): A command line tool to rewrite a JSON, with all whitespaces removed.
+ * [pretty](https://github.com/Tencent/rapidjson/blob/master/example/pretty/pretty.cpp): A command line tool to rewrite a JSON with indents and newlines by `PrettyWriter`.
+ * [capitalize](https://github.com/Tencent/rapidjson/blob/master/example/capitalize/capitalize.cpp): A command line tool to capitalize strings in JSON.
+ * [messagereader](https://github.com/Tencent/rapidjson/blob/master/example/messagereader/messagereader.cpp): Parse a JSON message with SAX API.

The example is a command line tool which converts input JSON into JSONx format.
