+* Removed example `IndentedPrintExample.ino`
+* Now compatible with Particle 0.6.1, thanks to Jacob Nite (issue #294 and PR #461 by @foodbag)
+
+v5.8.4
+------
+
+* Added custom implementation of `strtod()` (issue #453)
+* Added custom implementation of `strtol()` (issue #465)

+------
+
+* Added operator `==` to compare `JsonVariant` and strings (issue #402)
+* Added support for `Stream` (issue #300)
+* Reduced memory consumption by not duplicating spaces and comments
+
+### BREAKING CHANGES :warning:
+
+`JsonBuffer::parseObject()` and  `JsonBuffer::parseArray()` have been pulled down to the derived classes `DynamicJsonBuffer` and `StaticJsonBufferBase`.
+
+This means that if you have code like:
+
+```c++
+void myFunction(JsonBuffer& jsonBuffer);
+```
+
+you need to replace it with one of the following:
+
+```c++
+void myFunction(DynamicJsonBuffer& jsonBuffer);
+void myFunction(StaticJsonBufferBase& jsonBuffer);
+template<typename TJsonBuffer> void myFunction(TJsonBuffer& jsonBuffer);
+```
+
+

+* Added example `StringExample.ino` to show where `String` can be used
+* Increased default nesting limit to 50 when compiled for a computer (issue #349)
+
+### BREAKING CHANGES :warning:
+
+The non-template functions `JsonObject::get()` and `JsonArray.get()` have been removed. This means that you need to explicitely tell the type you expect in return.
+
+Old code:
+
+```c++
+#define ARDUINOJSON_USE_ARDUINO_STRING 0
+JsonVariant value1 = myObject.get("myKey");
+JsonVariant value2 = myArray.get(0);
+```
+
+New code:
+
+```c++
+#define ARDUINOJSON_ENABLE_ARDUINO_STRING 0
+#define ARDUINOJSON_ENABLE_STD_STRING 1
+JsonVariant value1 = myObject.get<JsonVariant>("myKey");
+JsonVariant value2 = myArray.get<JsonVariant>(0);
+```
+
+
+v5.6.7

+
+* Fixed `array[idx].as<JsonVariant>()` and `object[key].as<JsonVariant>()`
+* Fixed return value of `JsonObject::set()` (issue #350)
+* Fixed undefined behavior in `Prettyfier` and `Print` (issue #354)
+* Fixed parser that incorrectly rejected floats containing a `+` (issue #349)
+
+v5.6.6
+------
+
+* Fixed `-Wparentheses` warning introduced in v5.6.5 (PR #335 by @nuket)
+* Added `.mbedignore` for ARM mbdeb (PR #334 by @nuket)
+* Fixed  `JsonVariant::success()` which didn't propagate `JsonArray::success()` nor `JsonObject::success()` (issue #342).
+
+v5.6.5
+------
+
+* `as<char*>()` now returns `true` when input is `null` (issue #330)
+
+v5.6.4
+------
+
+* Fixed error in float serialization (issue #324)
+
+v5.6.3
+------
+
+* Improved speed of float serialization (about twice faster)
+* Added `as<JsonArray>()` as a synonym for `as<JsonArray&>()`... (issue #291)

+* Changed `::Print` to `ArduinoJson::Print` too
+
+v5.3.0
+------
+
+* Added custom implementation of `ftoa` (issues #266, #267, #269 and #270)
+* Added `JsonVariant JsonBuffer::parse()` (issue #265)
+* Fixed `unsigned long` printed as `signed long` (issue #170)
+
+v5.2.0
+------
+
+* Added `JsonVariant::as<char*>()` as a synonym for `JsonVariant::as<const char*>()` (issue #257)
+* Added example `JsonHttpClient` (issue #256)
+* Added `JsonArray::copyTo()` and `JsonArray::copyFrom()` (issue #254)
+* Added `RawJson()` to insert pregenerated JSON portions (issue #259)

+* Fixed `JsonVariant::is<bool>()` that was incorrectly returning false (issue #214)
+
+v5.0.7
+------
+
+* Made library easier to use from a CMake project: simply `add_subdirectory(ArduinoJson/src)`
+* Changed `String` to be a `typedef` of `std::string` (issues #142 and #161)
+
+### BREAKING CHANGES :warning:
+
+- `JsonVariant(true).as<String>()` now returns `"true"` instead of `"1"`
+- `JsonVariant(false).as<String>()` now returns `"false"` instead of `"0"`
+
+v5.0.6
+------
+
+* Added parameter to `DynamicJsonBuffer` constructor to set initial size (issue #152)
+* Fixed warning about library category in Arduino 1.6.6 (issue #147)
+* Examples: Added a loop to wait for serial port to be ready (issue #156)
+
+v5.0.5
+------
+
+* Added overload `JsonObjectSuscript::set(value, decimals)` (issue #143)
+* Use `float` instead of `double` to reduce the size of `JsonVariant` (issue #134)

+* 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)

+
+### BREAKING CHANGES :warning:
+
+- `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

+
+	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 a buffer overrun in JSON Parser (issue #5)
+
+v2.0
+----
+
+* Added JSON encoding (issue #2)

+
+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

-====================================
+ArduinoJson - C++ JSON library for IoT
+====================
 
-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) [![Star this project](http://githubbadges.com/star.svg?user=bblanchon&repo=ArduinoJson&style=flat&color=fff&background=007ec6)](https://github.com/bblanchon/ArduinoJson)

-How to  use ?
+Documentation
 -------------
 
-### 1. Install the library
-
-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.
-   
-
-Memory usage
-------------
-
-Here are the size of the main classes of the library.
-
-This table is for an 8-bit Arduino, types would be bigger on a 32-bit processor.
-
-<table>
-    <tr>
-        <th>Type</th>
-        <th>Size in bytes</th>
-    </tr>
-    <tr>
-        <td>Parser&lt;N&gt;</td>
-        <td>8 x N</td>
-    </tr>
-    <tr>
-        <td>JsonArray</td>
-        <td>4</td>
-    </tr>
-    <tr>
-        <td>JsonHashTable</td>
-        <td>4</td>
-    </tr>
-</table> 
-
-
-Code size
----------
-
-Theses tables has been created by analyzing the map file generated by AVR-GCC after adding `-Wl,-Map,foo.map` to the command line.
-
-As you'll see the code size if between 1680 and 3528 bytes, depending on the features you use.
