-Arduino JSON library: change log
-================================
+ArduinoJson: change log
+=======================
 
-v2.0
+HEAD
 ----
 
-* Added JSON encoding.
-* Renamed the library `ArduinoJsonParser` becomes `ArduinoJson`
+* Fix compatibility with the Blynk libary (issue #1914)
 
-**Breaking change**: you need to add the following line at the top of your program.
+v6.21.2 (2023-04-12)
+-------
 
-	using namespace ArduinoJson::Parser;
+* Fix compatibility with the Zephyr Project (issue #1905)
+* Allow using PROGMEM outside of Arduino (issue #1903)
+* Set default for `ARDUINOJSON_ENABLE_PROGMEM` to `1` on AVR
 
-v1.2
-----
+v6.21.1 (2023-03-27)
+-------
 
-* Example: changed `char[] json` into `char json[]`. Damn it C# !
+* Double speed of `DynamicJsonDocument::garbageCollect()`
+* Fix compatibility with GCC 5.2 (issue #1897)
 
-v1.1
-----
+v6.21.0 (2023-03-14)
+-------
 
-* 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
+* Drop support for C++98/C++03. Minimum required is C++11.
+* Remove `ARDUINOJSON_NAMESPACE`; use `ArduinoJson` instead.
+* Make string support generic (issue #1807)
 
-v1.0 
-----
+v6.20.1 (2023-02-08)
+-------
 
-Initial release
+* Remove explicit exclusion of `as<char*>()` and `as<char>()` (issue #1860)
+  If you try to call them, you'll now get the same error message as any unsupported type.
+  You could also add a custom converter for `char*` and `char`.
+
+v6.20.0 (2022-12-26)
+-------
+
+* Add `JsonVariant::shallowCopy()` (issue #1343)
+* Fix `9.22337e+18 is outside the range of representable values of type 'long'`

+* Rename things in `ARDUINOJSON_NAMESPACE` to match the public names
+* Add documentation to most public symbols
+* Remove support for naked `char` (was deprecated since 6.18.0)
+
+> ### BREAKING CHANGES
+>
+> This release hides `JsonVariant`'s functions that were only intended for internal use.
+> If you were using them in your programs, you must replace with `operator[]` and `to<JsonVariant>()`, like so:
+>
+> ```c++
+> // before
+> JsonVariant a = variant.getElement(idx);
+> JsonVariant b = variant.getOrAddElement(idx);
+> JsonVariant c = variant.getMember(key);
+> JsonVariant d = variant.getOrAddMember(key);
+>
+> // after
+> JsonVariant a = variant[idx];
+> JsonVariant b = idx < variant.size() ? variant[idx] : variant[idx].to<JsonVariant>();
+> JsonVariant c = variant[key];
+> JsonVariant d = variant.containsKey(key) ? variant[key] : variant[key].to<JsonVariant>();
+> ```

+* PlatformIO: set `build.libArchive` to `false` (PR #1550 by @askreet)
+
+> ### BREAKING CHANGES
+>
+> #### Support for `char` removed
+>
+> We cannot cast a `JsonVariant` to a `char` anymore, so the following will break:
+> ```c++
+> char age = doc["age"];  //  error: no matching function for call to 'variantAs(VariantData*&)'
+> ```
+> Instead, you must use another integral type, such as `int8_t`:
+> ```c++
+> int8_t age = doc["age"];  // OK
+> ```
+>
+> Similarly, we cannot assign from a `char` anymore, so the following will break:
+> ```c++
+> char age;
+> doc["age"] = age;  // error: no matching function for call to 'VariantRef::set(const char&)'
+> ```
+> Instead, you must use another integral type, such as `int8_t`:
+> ```c++
+> int8_t age;
+> doc["age"] = age;  // OK
+> ```
+> A deprecation warning with the message "Support for `char` is deprecated, use `int8_t` or `uint8_t` instead" was added to allow a smooth transition.
+>
+> #### `as<T>()` always returns `T`
+>
+> Previously, `JsonVariant::as<T>()` could return a type different from `T`.
+> The most common example is `as<char*>()` that returned a `const char*`.
+> While this feature simplified a few use cases, it was confusing and complicated the
+> implementation of custom converters.
+>
+> Starting from this version, `as<T>` doesn't try to auto-correct the return type and always return `T`,
+> which means that you cannot write this anymore:
+>
+> ```c++
+> Serial.println(doc["sensor"].as<char*>());  // error: invalid conversion from 'const char*' to 'char*' [-fpermissive]
+> ```
+> 
+> Instead, you must write:
+>
+> ```c++
+> Serial.println(doc["sensor"].as<const char*>());  // OK
+> ```
+>
+> A deprecation warning with the message "Replace `as<char*>()` with `as<const char*>()`" was added to allow a smooth transition.
+>
+> #### `DeserializationError::NotSupported` removed
+>
+> On a different topic, `DeserializationError::NotSupported` has been removed.
+> Instead of returning this error:
+>
+> * `deserializeJson()` leaves `\uXXXX` unchanged (only when `ARDUINOJSON_DECODE_UNICODE` is `0`)
+> * `deserializeMsgPack()` replaces unsupported values with `null`s
+>
+> #### Const-aware `is<T>()`
+>
+> Lastly, a very minor change concerns `JsonVariantConst::is<T>()`.
+> It used to return `true` for `JsonArray` and `JsonOject`, but now it returns `false`.
+> Instead, you must use `JsonArrayConst` and `JsonObjectConst`.
+
+v6.17.3 (2021-02-15)

+* Added `StaticJsonDocument::garbageCollect()`
+* Changed copy-constructor of `BasicJsonDocument` to preserve the capacity of the source.
+* Removed copy-constructor of `JsonDocument` (issue #1189)
+
+> ### BREAKING CHANGES
+> 
+> #### Copy-constructor of `BasicJsonDocument`
+>
+> In previous versions, the copy constructor of `BasicJsonDocument` looked at the source's `memoryUsage()` to choose its capacity.
+> Now, the copy constructor of `BasicJsonDocument` uses the same capacity as the source.
+>
+> Example:
+>
+> ```c++
+> DynamicJsonDocument doc1(64);
+> doc1.set(String("example"));
+>
+> DynamicJsonDocument doc2 = doc1;
+> Serial.print(doc2.capacity());  // 8 with ArduinoJson 6.14
+>                                 // 64 with ArduinoJson 6.15
+> ```
+>
+> I made this change to get consistent results between copy-constructor and move-constructor, and whether RVO applies or not.
+>
+> If you use the copy-constructor to optimize your documents, you can use `garbageCollect()` or `shrinkToFit()` instead.
+>
+> #### Copy-constructor of `JsonDocument`
+>
+> In previous versions, it was possible to create a function that take a `JsonDocument` by value.
+>
+> ```c++
+> void myFunction(JsonDocument doc) {}
+> ```
+>
+> This function gives the wrong clues because it doesn't receive a copy of the `JsonDocument`, only a sliced version.
+> It worked because the copy constructor copied the internal pointers, but it was an accident.
+>
+> From now, if you need to pass a `JsonDocument` to a function, you must use a reference:
+>
+> ```c++
+> void myFunction(JsonDocument& doc) {}
+> ```
+
+v6.14.1 (2020-01-27)
+-------

+
+> ### BREAKING CHANGES
+> 
+> #### Comments
+> 
+> Support for comments in input is now optional and disabled by default.
+>
+> If you need support for comments, you must defined `ARDUINOJSON_ENABLE_COMMENTS` to `1`; otherwise, you'll receive `InvalidInput` errors.
+>
+> ```c++
+> #define ARDUINOJSON_ENABLE_COMMENTS 1
+> #include <ArduinoJson.h>

+
+> ### BREAKING CHANGES
+> 
+> #### NaN and Infinity
+> 
+> The JSON specification allows neither NaN not Infinity, but previous
+> versions of ArduinoJson supported it. Now, ArduinoJson behaves like most
+> other libraries: a NaN or and Infinity in the `JsonDocument`, becomes
+> a `null` in the output JSON. Also, `deserializeJson()` returns
+> `InvalidInput` if the JSON document contains NaN or Infinity.
+> 
+> This version still supports NaN and Infinity in JSON documents, but
+> it's disabled by default to be compatible with other JSON parsers.
+> If you need the old behavior back, define `ARDUINOJSON_ENABLE_NAN` and
+> `ARDUINOJSON_ENABLE_INFINITY` to `1`;:
+> 
+> ```c++
+> #define ARDUINOJSON_ENABLE_NAN 1
+> #define ARDUINOJSON_ENABLE_INFINITY 1
+> #include <ArduinoJson.h>
+> ```
+> 
+> #### The "or" operator
+> 
+> This version slightly changes the behavior of the | operator when the 
+> variant contains a float and the user requests an integer.
+>
+> Older versions returned the floating point value truncated.
+> Now, it returns the default value.
+> 
+> ```c++
+> // suppose variant contains 1.2
+> int value = variant | 3;
+> 
+> // old behavior:
+> value == 1
+> 
+> // new behavior
+> value == 3
+> ```
+> 
+> If you need the old behavior, you must add `if (variant.is<float>())`.
+
+v6.10.1 (2019-04-23)
+-------
+
+* Fixed error "attributes are not allowed on a function-definition"
+* Fixed `deserializeJson()` not being picky enough (issue #969)
+* Fixed error "no matching function for call to write(uint8_t)" (issue #972)
+
+v6.10.0 (2019-03-22)
+-------
+
+* Fixed an integer overflow in the JSON deserializer
+* Added overflow handling in `JsonVariant::as<T>()` and `JsonVariant::is<T>()`.
+   - `as<T>()` returns `0` if the integer `T` overflows
+   - `is<T>()` returns `false` if the integer `T` overflows
+* Added `BasicJsonDocument` to support custom allocator (issue #876)
+* Added `JsonDocument::containsKey()` (issue #938)
+* Added `JsonVariant::containsKey()`
+
+v6.9.1 (2019-03-01)
+------

+* Fixed warning "unused variable" with GCC 4.4 (issue #912)
+* Fixed warning "cast  increases required alignment" (issue #914)
+* Fixed warning "conversion may alter value" (issue #914)
+* Fixed naming conflict with "CAPACITY" (issue #839)
+* Muted warning "will change in GCC 7.1" (issue #914)
+* Added a clear error message for `StaticJsonBuffer` and `DynamicJsonBuffer`
+* Marked ArduinoJson.h  as a "system header"
+
+v6.9.0 (2019-02-26)
+------
+
+* Decode escaped Unicode characters like \u00DE (issue #304, PR #791)
+  Many thanks to Daniel Schulte (aka @trilader) who implemented this feature.
+* Added option ARDUINOJSON_DECODE_UNICODE to enable it
+* Converted `JsonArray::copyFrom()/copyTo()` to free functions `copyArray()`
+* Renamed `JsonArray::copyFrom()` and `JsonObject::copyFrom()` to `set()`
+* Renamed `JsonArray::get()` to `getElement()`
+* Renamed `JsonArray::add()` (without arg) to `addElement()`
+* Renamed `JsonObject::get()` to `getMember()`
+* Renamed `JsonObject::getOrCreate()` to `getOrAddMember()`
+* Fixed `JsonVariant::isNull()` not returning `true` after `set((char*)0)`
+* Fixed segfault after `variant.set(serialized((char*)0))`
+* Detect `IncompleteInput` in `false`, `true`, and `null`
+* Added `JsonDocument::size()`
+* Added `JsonDocument::remove()`
+* Added `JsonVariant::clear()`
+* Added `JsonVariant::remove()`
+
+v6.8.0-beta (2019-01-30)
+-----------
+
+* Import functions in the ArduinoJson namespace to get clearer errors
+* Improved syntax highlighting in Arduino IDE
+* Removed default capacity of `DynamicJsonDocument`
+* `JsonArray::copyFrom()` accepts `JsonArrayConst`
+* `JsonVariant::set()` accepts `JsonArrayConst` and `JsonObjectConst`
+* `JsonDocument` was missing in the ArduinoJson namespace
+* Added `memoryUsage()` to `JsonArray`, `JsonObject`, and `JsonVariant`
+* Added `nesting()` to `JsonArray`, `JsonDocument`, `JsonObject`, and `JsonVariant`
+* Replaced `JsonDocument::nestingLimit` with an additional parameter
+  to `deserializeJson()` and `deserializeMsgPack()`
+* Fixed uninitialized variant in `JsonDocument`
+* Fixed `StaticJsonDocument` copy constructor and copy assignment
+* The copy constructor of `DynamicJsonDocument` chooses the capacity according to the memory usage of the source, not from the capacity of the source.
+* Added the ability to create/assign a `StaticJsonDocument`/`DynamicJsonDocument` from a `JsonArray`/`JsonObject`/`JsonVariant`
+* Added `JsonDocument::isNull()`
+* Added `JsonDocument::operator[]`
+* Added `ARDUINOJSON_TAB` to configure the indentation character
+* Reduced the size of the pretty JSON serializer
+* Added `add()`, `createNestedArray()` and `createNestedObject()` to `JsonVariant`
+* `JsonVariant` automatically promotes to `JsonObject` or `JsonArray` on write.
+  Calling `JsonVariant::to<T>()` is not required anymore.
+* `JsonDocument` now support the same operations as `JsonVariant`.
+  Calling `JsonDocument::as<T>()` is not required anymore.
+* Fixed example `JsonHttpClient.ino`
+* User can now use a `JsonString` as a key or a value
+
+> ### BREAKING CHANGES
+> 
+> #### `DynamicJsonDocument`'s constructor
+> 
+> The parameter to the constructor of `DynamicJsonDocument` is now mandatory
+>
+> Old code:
+>
+> ```c++
+> DynamicJsonDocument doc;
+> ```
+>
+> New code:
+>
+> ```c++
+> DynamicJsonDocument doc(1024);
+> ```
+> 
+> #### Nesting limit
+> 
+> `JsonDocument::nestingLimit` was replaced with a new parameter to `deserializeJson()` and `deserializeMsgPack()`.
+> 
+> Old code:
+> 
+> ```c++
+> doc.nestingLimit = 15;
+> deserializeJson(doc, input);
+> ```
+> 
+> New code: 
+> 
+> ```c++
+> deserializeJson(doc, input, DeserializationOption::NestingLimit(15));
+> ```
+
+v6.7.0-beta (2018-12-07)

+* Fixed `serializeJson(obj[key], dst)` (issue #794)
+
+> ### BREAKING CHANGES
+>
+> #### JsonVariant
+> 
+> `JsonVariant` now has a semantic similar to `JsonObject` and `JsonArray`.
+> It's a reference to a value stored in the `JsonDocument`.
+> As a consequence, a `JsonVariant` cannot be used as a standalone variable anymore.
+>
+> Old code:
+>
+> ```c++
+> JsonVariant myValue = 42;
+> ```
+>
+> New code:
+>
+> ```c++
+> DynamicJsonDocument doc;
+> JsonVariant myValue = doc.to<JsonVariant>();
+> myValue.set(42);
+> ```
+>
+> #### JsonPair
+>
+> Old code:
+>
+> ```c++
+> for(JsonPair p : myObject) {
+>   Serial.println(p.key);
+>   Serial.println(p.value.as<int>());
+> }
+> ```
+>
+> New code:

+>   Serial.println(p.key());
+>   Serial.println(p.value().as<int>());
+> }

+>
+> #### Preformatted values
+>
+> Old code:
+>
+> ```c++
+> object["values"] = RawJson("[1,2,3,4]");
+> ```
+> 
+> New code:
+> 
+> ```c++
+> object["values"] = serialized("[1,2,3,4]");

+-----------
+
+* Return `JsonArray` and `JsonObject` by value instead of reference (issue #309)
+* Replaced `success()` with `isNull()`
+
+> ### BREAKING CHANGES
+> 
+> Old code:
+>
+> ```c++
+> JsonObject& obj = doc.to<JsonObject>();
+> JsonArray& arr = obj.createNestedArray("key");
+> if (!arr.success()) {
+>   Serial.println("Not enough memory");
+>   return;
+> }
+> ```
+> 
+> New code:

-Arduino JSON library - Generator
-================================
-
-This library is a simple JSON encoder for embedded systems.
-
-It's design to be very lightweight, works without any allocation on the heap (no malloc) and supports nested objects.
-
-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
---------
-
-* Supports nested objects
-* Elegant API, very easy to use 
-* Fixed memory allocation (no malloc)
-* Small footprint
-* Implements Arduino's Printable interface
-* MIT License
-
-
-Example
--------
-
-    JsonArray<2> array;
-    array.add<6>(48.756080);
-    array.add<6>(2.302038);
-
-    JsonHashTable<3> root;
-    root.add("sensor", "gps");
-    root.add("time", 1351824120);
-    root.add("data", array);
-
-    Serial.print(root); // {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}
-
-
-How to  use?
-------------
-
-### 1. Install the library
-
-Download the library and extract it to:
-
-    <your Arduino Sketch folder>/libraries/ArduinoJson
-
-### 2. Import in your sketch
-
-Just add the following lines at the top of your `.ino` file:
-
-    #include <JsonGenerator.h>
-
-    using namespace ArduinoJson::Generator;
-   
-### 3. Create object tree
-
-In order to generate a JSON string, you need to build the equivalent object tree. You usually start by the root which can be either an array or an hash-table.
-
-#### Array
-
-You create an array with the following line:
-
-    JsonArray<8> array;
-
-See the little `<8>`? It's a template parameter that gives the capacity of the array, it's the maximum number of elements you can put in it. 
-
-> ##### About the capacity
-> As stated in the feature list, this library works with a fixed memory allocation.
-> This means that the size of the object must be know at the compilation time, therefore you can **not** use a variable to set the capacity of the array.
-
-Then you can add strings, integer, booleans, etc: 
-
-    array.add("bazinga!");
-    array.add(42);
-    array.add(true);
-
-There are two syntaxes for the floating point values:
-
-	array.add<4>(3.1415);  // 4 digits: "3.1415" 
-    array.add(3.14);	   // 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. 
-
-Finally you can add nested object to the array:
-
-    JsonArray<8> nestedArray;
-    array.add(nestedArray);
-
-or
-
-    JsonHashTable<8> nestedHash;
-    array.add(nestedHash);
-
-#### Hash-table
-
-You create a hash-table with the following line:
-
-    JsonHashTable<8> hash;
-
-Like with the array class, there is a template parameter that gives the capacity of the hash-table.
-
-Then you can add strings, integer, booleans, etc: 
-
-    hash.add("key1", "bazinga!");
-    hash.add("key2", 42);
-    hash.add("key3", true);
-
-As for the arrays, there are two syntaxes for the floating point values:
-
-	array.add<4>("key4", 3.1415);  // 4 digits: "3.1415" 
-    array.add("key5", 3.14);	   // 2 digits: "3.14"
-
-Finally you can add nested objects:
-
-    JsonArray<8> nestedArray;
-    hash.add("key6", nestedArray);
-
-or
-
-    JsonHashTable<8> nestedHash;
-    hash.add("key7", nestedHash);
-
-### 4. Get 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 stream like `Serial` or `EthernetClient `.
-
-Both ways are the easy way :-)
-
-#### Use a classic `char[]`
-
-Whether you have a `JsonArray` or a `JsonHashTable`, simply call `printTo()` with the destination buffer, like so:
-
-	char buffer[256];
-    array.printTo(buffer, sizeof(buffer));
-
-#### Send to a stream
-
-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:
-
-	Serial.print(array);
-
-or
-

-> ##### About the Printable interface
-> `JsonArray` and `JsonHashTable` implement Arduino's `Printable` interface.
-> This is why you can call `Serial.print()` like in the example above.
-> You can do the same with any other implementation of `Print`:  `HardwareSerial`,  `SoftwareSerial`, `LiquidCrystal`, `EthernetClient`, `WiFiClient`...

-Arduino JSON library - Parser
-=============================
-
-This library is an thin C++ wrapper around the *jsmn* tokenizer: http://zserge.com/jsmn.html
-
-It's design to be very lightweight, works without any allocation on the heap (no malloc) and supports nested objects.
-
-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
-* Elegant API, very easy to use 
-* Fixed memory allocation (no malloc)
-* Small footprint
-* MIT License
-
-
-Example
--------
-
-    char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
-
-    JsonParser<32> parser;
-
-    JsonHashTable root = parser.parseHashTable(json);
-
-    char* sensor = root.getString("sensor");
-
-    long time = root.getLong("time");
-    
-    JsonArray coords = root.getArray("data");
-
-
-How to  use ?
--------------
-
-### 1. Install the library
-
-Download the library and extract it to:
-
-    <your Arduino Sketch folder>/libraries/ArduinoJson
-
-### 2. Import in your sketch
-
-Just add the following lines at the top of your `.ino` file:
-
-    #include <JsonParser.h>
-
-    using namespace ArduinoJson::Parser;
-    
-### 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.

-        <th>Type</th>
-        <th>Size in bytes</th>

-    </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 is between 1680 and 3528 bytes, depending on the features you use.

+### Deserialization
 
-"Parser size" was measured with a program parsing `{"sensor":"outdoor","value":25.6}`.
-For each library, I wrote a program that extracts a string and a float. I subtracted the size of a program doing the same without any JSON parsing involved. [Source files are here](https://gist.github.com/bblanchon/e8ba914a7109f3642c0f).

-Testimonials
-------------
+See the [tutorial on arduinojson.org](https://arduinojson.org/v6/doc/deserialization/)
 
-From Arduino's Forum user `jflaplante`:
-> I tried the  [aJson and 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.
+### Serialization
 
-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.
+Here is a program that generates a JSON document with ArduinoJson:
 
-From StackOverflow user `thegreendroid`:
-> It has a really elegant, simple API and it works like a charm on embedded and Windows/Linux platforms. We recently started using this on an embedded project and I can vouch for its quality.
+```c++
+DynamicJsonDocument doc(1024);

+// This example shows how to send a JSON document to a UDP socket.
+// At regular interval, it sends a UDP packet that contains the status of
+// analog and digital pins.
+// It looks like that:
+// {
+//   "analog": [0, 76, 123, 158, 192, 205],
+//   "digital": [1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 0, 0]
+// }
+//
+// If you want to test this program, you need to be able to receive the UDP
