 ## 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.
