-ArduinoJsonParser change log
-============================
+ArduinoJson: change log
+=======================
+
+v5.0.2
+------
+
+* Fixed segmentation fault in `parseObject(String)` and `parseArray(String)`, when the 
+  `StaticJsonBuffer` is too small to hold a copy of the string
+* Fixed Clang warning "register specifier is deprecated" (issue #102)
+* Fixed GCC warning "declaration shadows a member" (issue #103)
+* Fixed memory alignment, which made ESP8266 crash (issue #104)
+* Fixed compilation on Visual Studio 2010 and 2012 (issue #107)
+
+v5.0.1
+------
+
+* Fixed compilation with Arduino 1.0.6 (issue #99)
+
+v5.0.0
+------
+
+* Added support of `String` class (issues #55, #56, #70, #77)
+* Added `JsonBuffer::strdup()` to make a copy of a string (issues #10, #57)
+* Implicitly call `strdup()` for `String` but not for `char*` (issues #84, #87)
+* Added support of non standard JSON input (issue #44)
+* Added support of comments in JSON input (issue #88)
+* Added implicit cast between numerical types (issues #64, #69, #93)
+* Added ability to read number values as string (issue #90)
+* Redesigned `JsonVariant` to leverage converting constructors instead of assignment operators (issue #66)
+* Switched to new the library layout (requires Arduino 1.0.6 or above)
+
+**BREAKING CHANGES**:
+- `JsonObject::add()` was renamed to `set()`
+- `JsonArray::at()` and `JsonObject::at()` were renamed to `get()`
+- Number of digits of floating point value are now set with `double_with_n_digits()`
+
+**Personal note about the `String` class**:
+Support of the `String` class has been added to the library because many people use it in their programs.
+However, you should not see this as an invitation to use the `String` class.
+The `String` class is **bad** because it uses dynamic memory allocation.
+Compared to static allocation, it compiles to a bigger, slower program, and is less predictable.
+You certainly don't want that in an embedded environment!
+
+v4.6
+----
+
+* Fixed segmentation fault in `DynamicJsonBuffer` when memory allocation fails (issue #92)
+
+v4.5
+----
+
+* Fixed buffer overflow when input contains a backslash followed by a terminator (issue #81)
+
+**Upgrading is recommended** since previous versions contain a potential security risk.
+
+Special thanks to [Giancarlo Canales Barreto](https://github.com/gcanalesb) for finding this nasty bug.
+
+v4.4
+----
+
+* Added `JsonArray::measureLength()` and `JsonObject::measureLength()` (issue #75)
+
+v4.3
+----
+
+* Added `JsonArray::removeAt()` to remove an element of an array (issue #58)
+* Fixed stack-overflow in `DynamicJsonBuffer` when parsing huge JSON files (issue #65)
+* Fixed wrong return value of `parseArray()` and `parseObject()` when allocation fails (issue #68)
+
+v4.2
+----
+
+* Switched back to old library layout (issues #39, #43 and #45)
+* Removed global new operator overload (issue #40, #45 and #46)
+* Added an example with EthernetServer
+
+v4.1
+----
+
+* Added DynamicJsonBuffer (issue #19)
+
+v4.0
+----
+
+* Unified parser and generator API (issue #23)
+* Updated library layout, now requires Arduino 1.0.6 or newer
+
+**BREAKING CHANGE**: API changed significantly, see [Migrating code to the new API](https://github.com/bblanchon/ArduinoJson/wiki/Migrating-code-to-the-new-API).
+
+
+v3.4
+----
+
+* Fixed escaped char parsing (issue #16)
+
+
+v3.3
+----
+
+* Added indented output for the JSON generator (issue #11), see example bellow.
+* Added `IndentedPrint`, a decorator for `Print` to allow indented output
+
+Example:
+
+    JsonOject<2> json;
+    json["key"] = "value";
+    json.prettyPrintTo(Serial);
+
+v3.2
+----
+
+* Fixed a bug when adding nested object in `JsonArray` (bug introduced in v3.1).
+
+v3.1
+----
+
+* Calling `Generator::JsonObject::add()` twice with the same `key` now replaces the `value`
+* Added `Generator::JsonObject::operator[]`, see bellow the new API
+* Added `Generator::JsonObject::remove()` (issue #9)
+
+Old generator API:
+
+	JsonObject<3> root; 
+    root.add("sensor", "gps");
+    root.add("time", 1351824120);
+    root.add("data", array);
+
+New generator API:
+
+	JsonObject<3> root; 
+    root["sensor"] = "gps";
+    root["time"] = 1351824120;
+    root["data"] = array;
+
+v3.0
+----
+
+* New parser API, see bellow
+* Renamed `JsonHashTable` into `JsonObject`
+* Added iterators for `JsonArray` and `JsonObject` (issue #4)
+
+Old parser API:
+
+    JsonHashTable root = parser.parseHashTable(json);
+
+	char*  sensor    = root.getString("sensor");
+	long   time      = root.getLong("time");
+	double latitude  = root.getArray("data").getDouble(0);
+    double longitude = root.getArray("data").getDouble(1);
+
+New parser API:
+
+	JsonObject root = parser.parse(json);
+
+	char*  sensor    = root["sensor"];
+    long   time      = root["time"];
+    double latitude  = root["data"][0];
+    double longitude = root["data"][1];
+
+v2.1
+----
+
+* Fixed case `#include "jsmn.cpp"` which caused an error in Linux (issue #6)
+* Fixed a buffer overrun in JSON Parser (issue #5)
+
+v2.0
+----
+
+* Added JSON encoding (issue #2)
+* Renamed the library `ArduinoJsonParser` becomes `ArduinoJson`
+
+**Breaking change**: you need to add the following line at the top of your program.
+
+	using namespace ArduinoJson::Parser;
+
+v1.2
+----
+
+* Fixed error in JSON parser example (issue #1)
 
 v1.1
 ----
 
-* Example: changed `char* json` into `char json[]` so that the byes are not write protected
+* Example: changed `char* json` into `char[] json` so that the bytes are not write protected
 * Fixed parsing bug when the JSON contains multi-dimensional arrays

-An efficient JSON parser for Arduino
-====================================
+Arduino JSON library
+====================
 
-This library is an thin C++ wrapper around the *jsmn* tokenizer: http://zserge.com/jsmn.html
+[![Build status](https://ci.appveyor.com/api/projects/status/m7s53wav1l0abssg/branch/master?svg=true)](https://ci.appveyor.com/project/bblanchon/arduinojson/branch/master) [![Build Status](https://travis-ci.org/bblanchon/ArduinoJson.svg?branch=master)](https://travis-ci.org/bblanchon/ArduinoJson) [![Coverage Status](https://img.shields.io/coveralls/bblanchon/ArduinoJson.svg)](https://coveralls.io/r/bblanchon/ArduinoJson?branch=master) 
 
-It's design to be very lightweight, works without any allocation on the heap (no malloc) and supports nested objects.
+*An elegant and efficient JSON library for embedded systems.*
 
-It has been written with Arduino in mind, but it isn't linked to Arduino libraries so you can use this library on any other C++ project.
+It's designed to have the most intuitive API, the smallest footprint and works without any allocation on the heap (no malloc).
 
+It has been written with Arduino in mind, but it isn't linked to Arduino libraries so you can use this library in any other C++ project.
 
 Features
 --------
 
-* Based on the well-proven [jsmn](http://zserge.com/jsmn.html) tokenizer
-* Supports nested objects
-* Works with fixed memory allocation : no `malloc()`
-* Low footprint
+* JSON decoding (comments are supported)
+* JSON encoding (with optional indentation)
+* Elegant API, very easy to use
+* Efficient (no malloc, nor copy)
+* Portable (written in C++98)
+* Self-contained (no external dependency)
+* Small footprint
 * MIT License
 
+Quick start
+-----------
 
-Example
--------
+#### Decoding / Parsing
 
-    char json[] = "{\"Name\":\"Blanchon\",\"Skills\":[\"C\",\"C++\",\"C#\"],\"Age\":32,\"Online\":true}";
+    char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
 
-    JsonParser<32> parser;
+    StaticJsonBuffer<200> jsonBuffer;
 
-    JsonHashTable hashTable = parser.parseHashTable(json);
+    JsonObject& root = jsonBuffer.parseObject(json);
 
-    if (!hashTable.success())
-    {
-        return;
-    }
+    const char* sensor = root["sensor"];
+    long time          = root["time"];
+    double latitude    = root["data"][0];
+    double longitude   = root["data"][1];
 
-    char* name = hashTable.getString("Name");
+#### Encoding / Generating
 
-    JsonArray skills = hashTable.getArray("Skills");
+    StaticJsonBuffer<200> jsonBuffer;
 
-    int age = hashTable.getLong("Age");
+    JsonObject& root = jsonBuffer.createObject();
+    root["sensor"] = "gps";
+    root["time"] = 1351824120;
 
-    bool online = hashTable.getBool("Online");
+    JsonArray& data = root.createNestedArray("data");
+    data.add(48.756080, 6);  // 6 is the number of decimals to print
+    data.add(2.302038, 6);   // if not specified, 2 digits are printed
+
+    root.printTo(Serial);
+    // This prints:
+    // {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}

-How to  use ?
+Documentation
 -------------
 
-### 1. Install the library
+The documentation is available online in the [Arduino JSON wiki](https://github.com/bblanchon/ArduinoJson/wiki)
 
-Download the library and extract it to:
-
-    <your Arduino Sketch folder>/libraries/ArduinoJsonParser
-
-### 2. Import in your sketch
-
-Just add the following line on the top of your `.ino` file:
-
-    #include <JsonParser.h>
-    
-### 3. Create a parser
-
-To extract data from the JSON string, you need to create a `JsonParser`, and specify the number of token you allocate for the parser itself:
-
-    JsonParser<32> parser;
-    
-> #### How to choose the number of tokens ?
-
-> A token is an element of the JSON object: either a key, a value, an hash-table or an array.
-> As an example the `char json[]` on the top of this page contains 12 tokens (don't forget to count 1 for the whole object and 1 more for the array itself).
-
-> The more tokens you allocate, the more complex the JSON can be, but also the more memory is occupied.
-> Each token takes 8 bytes, so `sizeof(JsonParser<32>)` is 256 bytes which is quite big in an Arduino with only 2KB of RAM.
-> Don't forget that you also have to store the JSON string in RAM and it's probably big.
-
-> 32 tokens may seem small, but it's very decent for an 8-bit processor, you wouldn't get better results with other JSON libraries.
-
-### 4. Extract data
-
-To use this library, you need to know beforehand what is the type of data contained in the JSON string, which is very likely.
-
-The root object has to be either a hash-table (like `{"key":"value"}`) or an array (like `[1,2]`). 
-
-The nested objects can be either arrays, booleans, hash-tables, numbers or strings.
-If you need other type, you can get the string value and parse it yourself.
-
-#### Hash-table
-
-Consider we have a `char json[]` containing to the following JSON string:
-
-    {
-        "Name":"Blanchon",
-        "Skills":[
-            "C",
-            "C++",
-            "C#"],
-        "Age":32,
-        "Online":true
-    }
-
-In this case the root object of the JSON string is a hash-table, so you need to extract a `JsonHashTable`:
-   
-    JsonHashTable root = parser.parseHashTable(json);
-    
-To check if the parsing was successful, you must check:
-
-    if (!root.success())
-    {
-        // Parsing fail: could be an invalid JSON, or too many tokens
-    }
-    
-And then extract the member you need:
-    
-    char* name = hashTable.getString("Name");
-
-    JsonArray skills = hashTable.getArray("Skills");
-
-    int age = hashTable.getLong("Age");
-
-    bool online = hashTable.getBool("Online");
-    
-#### Array
-
-Consider we have a `char json[]` containing to the following JSON string:
-
-    [
-        [ 1.2, 3.4 ],
-        [ 5.6, 7.8 ]               
-    ]
-
-In this case the root object of the JSON string is an array, so you need to extract a `JsonArray`:
-   
-    JsonArray root = parser.parseArray(json);
-    
-To check if the parsing was successful, you must check:
-
-    if (!root.success())
-    {
-        // Parsing fail: could be an invalid JSON, or too many tokens
-    }
-    
-And then extract the content by its index in the array:
-    
-    JsonArray row0 = root.getArray(0);
-    double a = row0.getDouble(0);
-    
-or simply:
-
-    double a = root.getArray(0).getDouble(0);
-
-
-Common pitfalls
----------------
-
-### 1. Not enough tokens
-
-By design, the library has no way to tell you why `JsonParser::parseArray()` or `JsonParser::parseHashTable()` failed.
-
-There are basically two reasons why they may fail:
-
-1. the JSON string is invalid
-2. the JSON string contains more tokens that the parser can store
-
-So, if you are sure the JSON string is correct and you still can't parse it, you should slightly increase the number of token of the parser.
-
-### 2. Not enough memory
-
-You may go into unpredictable trouble if you allocate more memory than your processor really has.
-It's a very common issue in embedded development. 
-
-To diagnose this, look at every big objects in you code and sum their size to check that they fit in RAM.
-
-For example, don't do this:
-
-    char json[1024];        // 1 KB
-    JsonParser<64> parser;    // 512 B
-
-because it may be too big for a processor with only 2 KB: you need free memory to store other variables and the call stack.
-
-That is why an 8-bit processor is not able to parse long and complex JSON strings.
-
-### 3. JsonParser not in memory
-
-To reduce the memory consumption, `JsonArray` and `JsonHashTable` contains pointer to the token that are inside the `JsonParser`. This can only work if the `JsonParser` is still in memory.
-
-For example, don't do this:
-
-    JsonArray getArray(char* json)
-    {
-        JsonParser<16> parser;
-        return parser.parseArray(parser); 
-    }
-
-because the local variable `parser` will be *removed* from memory when the function `getArray()` returns, and the pointer inside `JsonArray` will point to an invalid location.
-
-### 4. JSON string is altered
-
-This will probably never be an issue, but you need to be aware of this feature.
-
-When you pass a `char[]` to `JsonParser::parseArray()` or `JsonParser::parseHashTable()`, the content of the string will be altered to add `\0` at the end of the tokens.
-
-This is because we want functions like `JsonArray::getString()` to return a null-terminating string without any memory allocation.
-

+Testimonials
 ------------
 
-Here are the size of the main classes of the library.
+From Arduino's Forum user `jflaplante`:
+> I tried aJson json-arduino before trying your library. I always ran into memory problem after a while.
+> I have no such problem so far with your library. It is working perfectly with my web services.
 
-This table is for an 8-bit Arduino, types would be bigger on a 32-bit processor.
+From Arduino's Forum user `gbathree`:
+> Thanks so much - this is an awesome library!  If you want to see what we're doing with it - the project is located at www.photosynq.org.
