-Arduino JSON: change log
-========================
+ArduinoJson: change log
+=======================
+
+v5.7.1
+------
+
+* Added support for PROGMEM (issue #76)
+* Fixed compilation error when index is not an `int` (issue #381)
+
+v5.7.0
+------
+
+* Templatized all functions using `String` or `std::string`
+* Removed `ArduinoJson::String`
+* Removed `JsonVariant::defaultValue<T>()`
+* Removed non-template `JsonObject::get()` and `JsonArray.get()`
+* Fixed support for `StringSumHelper` (issue #184)
+* Replaced `ARDUINOJSON_USE_ARDUINO_STRING` by `ARDUINOJSON_ENABLE_STD_STRING` and `ARDUINOJSON_ENABLE_ARDUINO_STRING` (issue #378)
+* 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**:
+
+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)
+* Fixed `call of overloaded isinf(double&) is ambiguous` (issue #284)
+
+v5.6.2
+------
+
+* Fixed build when another lib does `#undef isnan` (issue #284)
+
+v5.6.1
+------
+
+* Added missing `#pragma once` (issue #310)
+
+v5.6.0
+------
+
+* ArduinoJson is now a header-only library (issue #199)
+
+v5.5.1
+------
+
+* Fixed compilation error with Intel Galileo (issue #299)
+
+v5.5.0
+------
+
+* Added `JsonVariant::success()` (issue #279)
+* Renamed `JsonVariant::invalid<T>()` to `JsonVariant::defaultValue<T>()`
+
+v5.4.0
+------
+
+* Changed `::String` to `ArduinoJson::String` (issue #275)
+* 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)
+
+v5.1.1
+------
+
+* Removed `String` duplication when one replaces a value in a `JsonObject` (PR #232 by @ulion)
+
+v5.1.0
+------
+
+* Added support of `long long` (issue #171)
+* Moved all build settings to `ArduinoJson/Configuration.hpp`
+
+**BREAKING CHANGE**:
+If you defined `ARDUINOJSON_ENABLE_STD_STREAM`, you now need to define it to `1`.
+
+v5.0.8
+------
+
+* Made the library compatible with [PlatformIO](http://platformio.org/) (issue #181)
+* 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**:
+- `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)
+
+v5.0.4
+------
+
+* Fixed ambiguous overload with `JsonArraySubscript` and `JsonObjectSubscript` (issue #122)
+
+v5.0.3
+------
+
+* Fixed `printTo(String)` which wrote numbers instead of strings (issue #120)
+* Fixed return type of `JsonArray::is<T>()` and some others (issue #121)
+
+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)

 Quick start
 -----------
 
 #### Decoding / Parsing
-   
-    char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
 
-    StaticJsonBuffer<200> jsonBuffer;
+```c++
+char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
 
-    JsonObject& root = jsonBuffer.parseObject(json);
+StaticJsonBuffer<200> jsonBuffer;
 
-    const char* sensor = root["sensor"];
-    long time          = root["time"];
-    double latitude    = root["data"][0];
-    double longitude   = root["data"][1];
+JsonObject& root = jsonBuffer.parseObject(json);
 
-[See complete guide](/doc/Decoding JSON.md)
+const char* sensor = root["sensor"];
+long time          = root["time"];
+double latitude    = root["data"][0];
+double longitude   = root["data"][1];
+```
 
 #### Encoding / Generating
-   
-    StaticJsonBuffer<200> jsonBuffer;
 
-    JsonObject& root = jsonBuffer.createObject();
-    root["sensor"] = "gps";
-    root["time"] = 1351824120;
+```c++
+StaticJsonBuffer<200> jsonBuffer;
 
-    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
+JsonObject& root = jsonBuffer.createObject();
+root["sensor"] = "gps";
+root["time"] = 1351824120;
 
-    root.printTo(Serial);
-    // This prints:
-    // {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}
+JsonArray& data = root.createNestedArray("data");

-Avoiding common pitfalls in Arduino JSON
-========================================
-
-As `StaticJsonBuffer` is the corner stone of this library, you'll see that every pitfall listed here are related to a wrong understanding of the memory model.
-
-Make sure you read [Arduino JSON memory model](Memory model.md) before going further.
-
-## 1. Make `StaticJsonBuffer` big enough
-
-By design, the library has no way to tell you why `parseArray()` or `parseObject()` failed.
-
-There are basically two reasons why they may fail:
-
-1. the JSON string is invalid,
-2. the JSON string contains more values that the buffer can store.
-
-So, if you are sure the JSON string is correct and you still can't parse it, you should try to increase the size of the `StaticJsonBuffer`.
-
-## 2. Make sure everything fits in 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
-    StaticJsonBuffer<512> buffer;   // 514 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. Keep the `StaticJsonBuffer` in memory long enough
-
-Remember that `StaticJsonBuffer`'s function return references.
-References don't contain data, they are just pointer to the actual.
-So they can only work if the actual data is in memory.
-
-For example, don't do this:
-
-    JsonArray& getArray(char* json)
-    {
-        StaticJsonBuffer<200> buffer;
-        return buffer.parseArray(json); 
-    }
-
-because the local variable `buffer` will be *removed* from memory when the function `parseArray()` returns, and the `JsonArray&` will point to an invalid location.
-
-## 4. Don't reuse the same `StaticJsonBuffer`
-
-During is lifetime a `StaticJsonBuffer` growth until it's discarded. If you try to reuse the same instance several time, it will rapidly get full.
-
-For this reason, you should not use a global variable for your `StaticJsonBuffer`. I don't think there is any scenario in which a global `StaticJsonBuffer` would be a valid option.
-
-The best practice is to declare it in a local scope, so that it's discarded as soon as possible. My advice it to declare it in a function which unique role is to handle the JSON serialization.
-
-## 5. Keep the JSON string in memory long enough
-
-The library never make memory duplication.
-This has an important implication on string values, it means that the library will return pointer to chunks of the string.
-
-For instance, let's imagine that you parse `["hello","world"]`, like this:
-
-    char[] json = "[\"hello\",\"world\"]";
-    StaticJsonBuffer<32> buffer;
-    JsonArray& array = buffer.parseArray(json);
-
-    const char* first = array[0];
-    const char* second = array[1];
-
-In that case, both `first` and `second` are pointers to the content of the original string `json`.
-So this will only work if `json` is still in memory.
-
-## 6. JSON string is altered
-
-If you read carefully the previous section, you may have come to the conclusion that the JSON parser modifies the JSON string.
-
-Indeed, the parser modifies the string for two reasons:
-
-1. it inserts `\0` to terminate substrings,
-2. it translate escaped characters like `\n` or `\t`.
-
-Most of the time this wont be an issue, but there are some corner cases that can be problematic.
-
-Let take the example bellow:
-
-    char[] json = "[\"hello\",\"world\"]";
-    StaticJsonBuffer<32> buffer;
-    JsonArray& array = buffer.parseArray(json);
-
-If you replace it by:
-
-    char* json = "[\"hello\",\"world\"]";
-    StaticJsonBuffer<32> buffer;
-    JsonArray& array = buffer.parseArray(json);
-
-Depending on your platform, you may have an exception because the parser tries to write at a location that is read-only.
-In the first case `char json[]` declares an array of `char` initialized to the specified string.
-In the second case `char* json` declares a pointer to a read-only string, in fact it should be a `const char*` instead of a `char*`.

-## Example
-
-Here an example that parse the string `{"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}`:
-
-    char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
-    
-    //
-    // Step 1: Reserve memory space
-    //
-    StaticJsonBuffer<200> jsonBuffer;
-    
-    //
-    // Step 2: Deserialize the JSON string
-    //
-    JsonObject& root = jsonBuffer.parseObject(json);
-
-    if (!root.success())
-    {
-      Serial.println("parseObject() failed");
-      return;
-    }
-
-    //
-    // Step 3: Retrieve the values
-    //
-    const char* sensor    = root["sensor"];
-    long        time      = root["time"];
-    double      latitude  = root["data"][0];
-    double      longitude = root["data"][1];
-
-## Step 1: Reserve memory space
-
-Arduino JSON uses a preallocated memory pool to store the object tree, this is done by the `StaticJsonBuffer`.
-
-Before continuing please read the page [Arduino JSON memory model](Memory model.md) that explains everything you need to know about `StaticJsonBuffer`.
-
-## Step 2: Parse the JSON string
-
-You invoke the JSON parser through the instance of `StaticJsonBuffer`.
-It exposes two functions for parsing JSON:
-
-1. `parseArray()` that returns a reference to a `JsonArray`
-2. `parseObject()` that returns a reference to a `JsonObject`
-
-Let's see an example.
-Say we want to parse `{"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}`, it's an object so we call `parseObject()` as follows:
-
-    char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
-
-    JsonObject& root = jsonBuffer.parseObject(json);
-
-As you can see `parseObject()` takes a `char*` as a parameter.
-Be careful, it's not a `const char*`, the memory must be writable.
-Indeed, the parser will modify the string in two cases:
-
-1. to insert string endings (character `\0`),
-2. to translate escaped characters (like `\n` or `\t`).
-
-Another thing that you must keep in mind is that the string (`char json[]` in the example above) must stay in memory during the whole parsing process.
-That is because the in memory object tree will store pointer to chunks of the string, so as to avoid any memory duplication. 
-
-Now, to check if the parsing was successful, you can call `JsonObject::success()`:
-
-    if (!root.success())
-    {
-        // Parsing fail
-    }
-
-The result can be `false` for tree reasons:
-
-1. the JSON string is invalid,
-2. the JSON string doesn't represent an object,
-3. the `StaticJsonBuffer` is too small.
-
-We just saw how to parse an object, there is nothing more to say for arrays, the procedure is exactly the same.
-
-## Step 3: Retrieve the values
-
-Now that the object or array is in memory, you can extract the data very easily.
-
-In this section, we'll see how to do it with a `JsonObject`.
-Once again, there is nothing more to say about arrays, `JsonArray` works exactly the same as `JsonObject`.
-
-#### Subscript operator
-
-The simplest way is to use the subscript operator of `JsonObject`:
-    
-    const char* sensor = root["sensor"];
-    long time = root["time"];
-
-You can chain the subscript operator if you have nested arrays or objects:
-
-    double latitude  = root["data"][0];
-    double longitude = root["data"][1];
-
-But alternatively, you can get a reference to the nested array:
-
-    JsonArray& nestedArray = root["data"];
-
-#### Casting values
-
-In the previous examples, the values were implicitly casted to the target type.
-You can also do this explicitly
-
-    const char* sensor = root["sensor"].asString();
-    long time = root["time"].as<long>();
-    JsonArray& nestedArray = root["data"].asArray();
-
-If the actual value doesn't match the target type, a default value will be return:
-
-1. `false` for boolean values
-2. `0` for integer values
-3. `NULL` for string values
-4. `JsonArray::invalid()` for nested arrays
-5. `JsonObject::invalid()` for nested object
-
-#### Check values
-
-If you want to know if some value is present, call `containsKey()`:
-
-    if (root.contains("extra"))
-    {
-        // root["extra"] is valid
-    }
-
-If you want to check the type value has a certain type, call `is<T>()`:
-
-    if (root["extra"].is<JsonArray&>())
-    {
-        // root["extra"] is an array
-    }
-
-You can also iterate through the key-value pairs of the object:
-
-    for (JsonObject::itertor it=root.begin(); it!=root.end(); ++it)
-    {
-      Serial.println(it->key);
-      Serial.println(i->value.asString());
-    }

-## Step 1: Reserve memory space
-
-Arduino JSON uses a preallocated memory pool to store the object tree, this is done by the `StaticJsonBuffer`.
-
-Before continuing please read the page [Arduino JSON memory model](Memory model.md) that explains everything you need to know about `StaticJsonBuffer`.
-
-## Step 2: Build object tree in memory
-
-Now that you have enough memory hold by the `StaticJsonBuffer`, you can use it to build your in-memory representation of the JSON string.
-
-#### Arrays
-
-You create an array like this:
-
-    JsonArray& array = jsonBuffer.createArray();
-
-Don't forget the `&` after `JsonArray`, it needs to be a reference to the array.
-
-Then you can add strings, integer, booleans, etc:
-
-    array.add("bazinga!");
-    array.add(42);
-    array.add(true);
-
-There are two syntaxes for floating point values:
-
-	array.add(3.1415, 4);  // 4 digits: "3.1415"
-    array.add(3.1415);	   // 2 digits: "3.14"
-
-> ##### About floating point precision
-> The overload of `add()` with 2 parameters allows you to specify the number of decimals to save in the JSON string.
-> When you use the overload with one parameter, you use the default number of decimals which is 2.
-> Note that this behavior is the exact same as Arduino's `Print::print(double,int);` which is implemented by `Serial`, so you may already be familiar with this behavior.
-
-You can add a nested array or object if you have a reference to it.
-Or simpler, you can create nested array or nested objects from the array:
-
-    JsonArray&  nestedArray  = array.createNestedArray();
-    JsonObject& nestedObject = array.createNestedObject();
-
-#### Objects
-
-You create an object like this:
-
-    JsonObject& object = jsonBuffer.createObject();
-
-Again, don't forget the `&` after `JsonObject`, it needs to be a reference to the object.
-
-Then you can add strings, integer, booleans, etc:
-
-    object["key1"] = "bazinga!";
-    object["key2"] = 42;
-    object["key3"] = true;
-
-As for the arrays, there are two syntaxes for the floating point values:
-
-	object["key4"].set(3.1415, 4);  // 4 digits "3.1415"
-    object["key5"] = 3.1415;	    // default: 2 digits "3.14"
-
-You can add a nested array or object if you have a reference to it.
-Or simpler, you can create nested array or nested objects from the object:
-
-    JsonArray&  nestedArray  = object.createNestedArray("key6");
-    JsonObject& nestedObject = object.createNestedObject("key7");
-
-> ##### Other JsonObject functions
-> * `object.add(key, value)` is a synonym for `object[key] = value`
-> * `object.containsKey(key)` returns `true` is the `key` is present in `object`
-> * `object.remove(key)` removes the `value` associated with `key`
-
-## Step 3: Generate the JSON string
-
-There are two ways tho get the resulting JSON string.
-
-Depending on your project, you may need to dump the string in a classic `char[]` or send it to a `Print` implementation like `Serial` or `EthernetClient `.
-
-Both ways are the easy way :-)
-
-#### Use a classic `char[]`
-
-Whether you have a `JsonArray&` or a `JsonObject&`, simply call `printTo()` with the destination buffer, like so:
-
-	char buffer[256];
-    array.printTo(buffer, sizeof(buffer));
-
-> ##### Want an indented output?
-> By default the generated JSON is as small as possible. It contains no extra space, nor line break.
-> But if you want an indented, more readable output, you can.
-> Simply call `prettyPrintTo` instead of `printTo()`:
-> 
->     array.prettyPrintTo(buffer, sizeof(buffer));
-
-#### Send to a `Print` implementation
-
-It's very likely that the generated JSON will end up in a stream like `Serial` or `EthernetClient `, so you can save some time and memory by doing this:
-
-    array.printTo(Serial);
-
-And, of course if you need an indented JSON string:
-
-    array.prettyPrintTo(Serial);
-
-> ##### About the Print interface
-> The library is designed to send the JSON string to an implementation of the `Print` interface that is part of Arduino.
-> In the example above we used `Serial`, but they are many other implementations that would work as well, including: `HardwareSerial`,  `SoftwareSerial`, `LiquidCrystal`, `EthernetClient`, `WiFiClient`, `Wire`...
-> When you use this library out of the Arduino environment, it will use it's own implementation of `Print` and everything will be the same.

-Arduino JSON memory model
-=========================
-
-## Fixed memory allocation
-
-### Introducing `StaticJsonBuffer`
-
-Arduino JSON uses a preallocated memory pool to store the object tree, this is done by the `StaticJsonBuffer` class.
-
-Before using any function of the library you need to create a `StaticJsonBuffer`. Then you can use this instance to create arrays and objects, or parse a JSON string.
-
-`StaticJsonBuffer` has a template parameter that determines its capacity. For example, the following line create a `StaticJsonBuffer` with a capacity of 200 bytes:
-
-    StaticJsonBuffer<200> jsonBuffer;
-
-The bigger the buffer is, the more complex the object tree can be, but also the more memory you need.
-
-### How to determine the buffer size?
-
-So the big question you should have in mind right now is *How can I determine the size?*.
-
-There are basically two approaches here:
-
-1. either you can predict the content of the object tree,
-2. or, you know how much memory is available.
-
-In the first case, you know some constraints on the object tree. For instance, let's say that your know in advance (and by that I mean "at compilation time") that you want to generate an object with 3 values, one of them being an array with 2 values, like the following:
-
-    {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}
-
-To determine the memory usage of this object tree, you use the two macros `JSON_ARRAY_SIZE(n)` and `JSON_OBJECT_SIZE(n)`, both take the number of elements as an argument.
-For the example above, it would be:
-
-    const int BUFFER_SIZE = JSON_OBJECT_SIZE(3) + JSON_ARRAY_SIZE(2);
-    StaticJsonBuffer<BUFFER_SIZE> jsonBuffer;
-
-In the second case, let's say you dynamically generate a JSON object tree of a random complexity so you can't put a limit based on that. But on the other hand, you don't want your program to crash because the object tree doesn't fit in memory.
-The solution here is to determine how much memory is available, or in other words how much memory you can afford for the JSON object tree.
-
-### Why choosing fixed allocation?
-
-This fixed allocation approach may seem a bit strange, especially if your a desktop application developer used to dynamic allocation, but it make a lot of sense in an embedded context:
-
-1. the code is smaller
-2. it uses less memory
-3. it doesn't create memory fragmentation
-4. it predictable
-
-Don't forget that the memory is "freed" as soon as the `StaticJsonBuffer` is out of scope, like any other variable. It only hold the memory for a short amount of time.

-| JsonArray of N element  | 4 + 8 * N  |
-| JsonObject of N element | 4 + 10 * N |

-Migrating code written for Arduino JSON v3 to v4
-================================================
-
-Arduino JSON v4 was a major rewrite of the library, and the API changed significantly.
-
-## Includes
-
-Arduino JSON v3 had two include files:
-
-    #include <JsonParser.h>
-    #include <JsonGenerator.h>
-
-Arduino JSON v4 only has one:
-
-	#include <ArduinoJson.h>
-
-## Namespaces
-
-Arduino JSON v3 had two namespaces:
-
-	using namespace ArduinoJson::Parser;
-	using namespace ArduinoJson::Generator;
-
-Arduino JSON v4 doesn't require the `using namespace` statement.
-It has a namespace but the `using namespace` is done in the header file.
-
-## StaticJsonBuffer
-
-Arduino JSON v3 had different memory allocation models for the parser:
-
-	JsonParser<16> parser; // 16 being the capacity in "tokens"
-
-and for the generator:
-
-	JsonArray<4> array; // 4 being the number of element
-	JsonObject<4> object;
-
-Arduino JSON v4 only has one memory allocation model:
-
-	StaticJsonBuffer<128> buffer; // 128 being the capacity in bytes
-
-## Return values for the parser
-
-Arduino JSON v3 returned value types:
-
-	JsonArray array = parser.parseArray(json);
-	JsonObject object = parser.parseObject(json);
-
-Arduino JSON v4 returns references types:
-
-	JsonArray& array = buffer.parseArray(json);
-	JsonObject& object = buffer.parseObject(json);
-
-Everything else is compatible
-
-## Creating arrays and objects
-
-Arduino JSON v3 allowed to create `JsonArray` and `JsonObject` directly:
-
-	JsonArray<4> array;
-	JsonObject<4> object;
-
-Arduino JSON v4 requires that you use a `StaticJsonBuffer` for that:
-
-	JsonArray& array = buffer.createArray();
-	JsonObject& object = buffer.createObject();
-
-Note: you don't have to specify the capacity anymore.
-
-## Printable interface
-
-Arduino JSON v3 used to implement the Printable interface, which allowed statements like:
-
-    Serial.print(array);
-
-But Arduino JSON v4 doesn't, instead you need to write this:
-
-	array.printTo(Serial);
-
-Note: there was a good reason for removing that feature, and it's reducing the size of `JsonArray` and `JsonObject`.

-==============================
-
-This library is primarily design to be used with the Arduino IDE and therefore has a simplified setup procedure for that environment.
-If you don't use the Arduino IDE, please read [Using the library without Arduino](Using the library without Arduino.md).
-
-## Install the library
-
-[Download the zip package](https://github.com/bblanchon/ArduinoJson/releases) and extract it to:
-
-    <your Arduino Sketch folder>/libraries/ArduinoJson
-
-Then restart the Arduino IDE.
-
-## Run the examples sketches
-
-Click `File` / `Example` / `ArduinoJson`.
-
-![Screen capture of Arduino IDE](http://i.imgur.com/g5UwkVh.png)
-
-## Use the library in your sketches
-
-Just add the following line at the top of your program:
-
-    #include <ArduinoJson.h>
-
-Then follow the instructions:
-
-1. [Parsing JSON](Parsin JSON.md)
-2. [Generating JSON](Generating JSON.md)

-
-This library is primarily design to be used with the Arduino IDE and therefore has a simplified setup procedure for that environment.
-If you use the Arduino IDE, please read [Using the library with Arduino](Using the library with Arduino.md).
-
-However, it can be used without Arduino IDE with very little effort.
-
-## Compiling the library
-
-Step 1: Download source code:
-
-    git clone https://github.com/bblanchon/ArduinoJson.git
-
-Step 2: Generate the `Makefile` for your environment
-
-    cd ArduinoJson
-    cmake .
-
-Step 3: Build
-
-	make
-
-## File paths
-
-Assuming you installed the library into `<arduino-json>`, you need to add:
-
-1. `<arduino-json>/include` to your include path
-2. `<arduino-json>/lib` to your library path
-
-
-----------
-
-You are now ready to follow the instructions:
-
-1. [Parsing JSON](Parsin JSON.md)
-2. [Generating JSON](Generating JSON.md)
