-========================
+ArduinoJson: change log
+=======================
+
+v5.0 (currently in beta)
+----
+
+* Added support of `String` class (issue #55, #56, #70, #77)
+* Added support of non standard JSON input (issue #44)
+* Redesigned `JsonVariant` to leverage converting constructors instead of assignment operators
+* 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!
+
+v4.5
+----
+
+* 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

-Avoiding common pitfalls in Arduino JSON
-========================================
-
-As `StaticJsonBuffer` is the corner stone of this library, you'll see that every pitfall listed here is 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 slightly increase the number of token of the parser.
-
-## 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
-    JsonParser<512> parser;    // 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 the function of `StaticJsonBuffer` return references.
-References don't store data, they are just pointer to the actual.
-This will only work if the data actual is still 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 make `StaticJsonBuffer` global
-
-If you read the previous point, you may come to the idea of using a global variable for your `StaticJsonBuffer`.
-This is probably a bad idea because `StaticJsonBuffer` can be quite big (depending on your requirement) and would be eating a lot of memory, even when you don't use it.
-
-There are some cases were a `StaticJsonBuffer` can be a global variable, but must of the time you should declare it in a local scope, 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 pointer 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 pitfall, you may I 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 it there are some corner case that can be problematic.
-
-Let take the example above:
-
-    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*`.

-
-    char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
-    
-    //

-    //
-    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 call the JSON parser through the instance of `StaticJsonBuffer`.
-It exposes two function 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<4>(3.1415);  // 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 two.
-> 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 it.
-
-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 array 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<4>(3.1415);  // 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 implementation 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`.
-
-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 the number of bytes that it contains. For example, the following line create a `StaticJsonBuffer` containing 200 bytes on the stack:
-
-    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)` `JSON_OBJECT_SIZE(n)`, both take the number of elements as a parameter.
-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 base 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 generation.
-
-### Why choosing fixed allocation?
-
-This fixed allocation approach may seem a bit strange, especially if your a desktop app 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.
-
-For that reason, you should never use a `StaticJsonBuffer` as a **global variable** because it would hold a lot of memory for the whole life of the program.

-| 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 change significantly.
-
-## Includes
-
-Arduino JSON v3 had two include files:
-
-    #include <JsonParser.h>
-    #include <JsonGenerator.h>
-
-Arduino JSON v4 only has one:
-
-	#include <ArduinoJson.h>
-
-Node: the header `src/ArduinoJson.h` is intended to be used within the Arduino IDE, if you're in another environment, you may need to include the following headers:
-
-	#include <ArduinoJson/StaticJsonBuffer.hpp>
-	#include <ArduinoJson/JsonObject.hpp>
-	#include <ArduinoJson/JsonArray.hpp>
-
-## Namespaces
-
-Arduino JSON v3 had two namespaces:
-
-	using namespace ArduinoJson::Parser;
-	using namespace ArduinoJson::Generator;
-
-Arduino JSON v4 only has one:
-
-	using namespace ArduinoJson;
-
-If you include the header `ArduinoJson.h` (recommended if in Arduino IDE), the `using` directivei is already done for you, so you don't have to write it.
-
-## StaticJsonBuffer
-
-Arduino JSON v3 had different memory allocation models for 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 mode:
-
-	StaticJsonBuffer<128> buffer; // 128 being the capacity in bytes
-
-## Return values for the parser
-
-Arduino JSON v3 returned `JsonArray` and `JsonObject`:
-
-	JsonArray array = parser.parseArray(json);
-	JsonObject object = parser.parseObject(json);
-
-Arduino JSON v4 returns references:
-
-	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, that allowed that kind of statement:
-
-    Serial.print(array);
-
-Arduino JSON v4 doesn't, so you need to write this:
-
-	array.printTo(Serial);
-
-Note: there is a good reason for that: reducing the size of `JsonArray` and `JsonObject`.

-
-## 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:

-This library is primarily design to be used with the Arduino IDE and therefore has a simplified setup procedure for that purpose.
-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)
