-Writeable Text entities have moved from type `sensor` to `text` in Home Assistant to make them also editable within an HA dashboard. Examples are `datetime`, `holidays`, `switchtime`, `vacations`, `maintenancedate`.

 > ### BREAKING CHANGES
 >
-> As every major release, ArduinoJson 7 introduces several breaking changes.
-> I added some stubs so that most existing programs should compile, but I highty recommend you upgrade your code.
->
-> #### `JsonDocument`
-> 
-> In ArduinoJson 6, you could allocate the memory pool on the stack (with `StaticJsonDocument`) or in the heap (with `DynamicJsonDocument`).  
-> In ArduinoJson 7, the memory pool is always allocated in the heap, so `StaticJsonDocument` and `DynamicJsonDocument` have been merged into `JsonDocument`.
->
-> In ArduinoJson 6, `JsonDocument` had a fixed capacity; in ArduinoJson 7, it has an elastic capacity that grows as needed.
-> Therefore, you don't need to specify the capacity anymore, so the macros `JSON_ARRAY_SIZE()`, `JSON_OBJECT_SIZE()`, and `JSON_STRING_SIZE()` have been removed.
+> 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++
-> // ArduinoJson 6
-> StaticJsonDocument<256> doc;
-> // or
-> DynamicJsonDocument doc(256);
+> // before
+> JsonVariant a = variant.getElement(idx);
+> JsonVariant b = variant.getOrAddElement(idx);
+> JsonVariant c = variant.getMember(key);
+> JsonVariant d = variant.getOrAddMember(key);
 >
-> // ArduinoJson 7
-> JsonDocument doc;
+> // 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>();
+> ```
+
+v6.19.4 (2022-04-05)

+
+* Add `ElementProxy::memoryUsage()`
+* Add `MemberProxy::memoryUsage()` (issue #1730)

+
+v6.19.0 (2022-01-08)
+-------

+* Change the default of `ARDUINOJSON_USE_DOUBLE` to `1`
+* Change the default of `ARDUINOJSON_USE_LONG_LONG` to `1` on 32-bit platforms
+* Add `as<JsonString>()` and `is<JsonString>()`
+* Add safe bool idiom in `JsonString`
+* Add support for NUL in string values (issue #1646)
+* Add support for arbitrary array rank in `copyArray()`
+* Add support for `char[][]` in `copyArray()`
+* Remove `DeserializationError == bool` and `DeserializationError != bool`
+* Renamed undocumented function `isUndefined()` to `isUnbound()`
+* Fix `JsonVariant::memoryUsage()` for raw strings
+* Fix `call of overloaded 'swap(BasicJsonDocument&, BasicJsonDocument&)' is ambiguous` (issue #1678)
+* Fix inconsistent pool capacity between `BasicJsonDocument`'s copy and move constructors
+* Fix inconsistent pool capacity between `BasicJsonDocument`'s copy and move assignments
+* Fix return type of `StaticJsonDocument::operator=`
+* Avoid pool reallocation in `BasicJsonDocument`'s copy assignment if capacity is the same
+* Avoid including `Arduino.h` when all its features are disabled (issue #1692, PR #1693 by @paulocsanz)
+* Assume `PROGMEM` is available as soon as `ARDUINO` is defined (consequence of #1693)

+
+> ### 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
 > ```
 >
-> In ArduinoJson 7, `JsonDocument` reuses released memory, so `garbageCollect()` has been removed.  
-> `shrinkToFit()` is still available and releases the over-allocated memory.
+> 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.
 >
-> Due to a change in the implementation, it's not possible to store a pointer to a variant from another `JsonDocument`, so `shallowCopy()` has been removed.
+> #### `as<T>()` always returns `T`
 >
-> In ArduinoJson 6, the meaning of `memoryUsage()` was clear: it returned the number of bytes used in the memory pool.  
-> In ArduinoJson 7, the meaning of `memoryUsage()` would be ambiguous, so it has been removed.
+> 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.
 >
-> #### Custom allocators
->
-> In ArduinoJson 6, you could specify a custom allocator class as a template parameter of `BasicJsonDocument`.  
-> In ArduinoJson 7, you must inherit from `ArduinoJson::Allocator` and pass a pointer to an instance of your class to the constructor of `JsonDocument`.
+> 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++
-> // ArduinoJson 6
-> class MyAllocator {
->   // ...
-> };
-> BasicJsonDocument<MyAllocator> doc(256);
->
-> // ArduinoJson 7
-> class MyAllocator : public ArduinoJson::Allocator {
->   // ...
-> };
-> MyAllocator myAllocator;
-> JsonDocument doc(&myAllocator);
+> Serial.println(doc["sensor"].as<char*>());  // error: invalid conversion from 'const char*' to 'char*' [-fpermissive]
 > ```
 > 
-> #### `createNestedArray()` and `createNestedObject()`
->
-> In ArduinoJson 6, you could create a nested array or object with `createNestedArray()` and `createNestedObject()`.  
-> In ArduinoJson 7, you must use `add<T>()` or `to<T>()` instead.
->
-> For example, to create `[[],{}]`, you would write:
+> Instead, you must write:
 >
 > ```c++
-> // ArduinoJson 6
-> arr.createNestedArray();
-> arr.createNestedObject();
->
-> // ArduinoJson 7
-> arr.add<JsonArray>();
-> arr.add<JsonObject>();
+> Serial.println(doc["sensor"].as<const char*>());  // OK
 > ```
 >
-> And to create `{"array":[],"object":{}}`, you would write:
+> 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`.

+
+> ### 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++
-> // ArduinoJson 6
-> obj.createNestedArray("array");
-> obj.createNestedObject("object");
+> DynamicJsonDocument doc1(64);
+> doc1.set(String("example"));
 >
-> // ArduinoJson 7
-> obj["array"].to<JsonArray>();
-> obj["object"].to<JsonObject>();
+> 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) {}
+> ```

+> 
+> #### Comments
+>

+
+> ### 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>())`.

+
+v6.2.3-beta (2018-07-19)
+-----------
+
+* Fixed exception when using Flash strings as object keys (issue #784)
+
+v6.2.2-beta (2018-07-18)
+-----------
+
+* Fixed `invalid application of 'sizeof' to incomplete type '__FlashStringHelper'` (issue #783)
+* Fixed `char[]` not duplicated when passed to `JsonVariant::operator[]`
+
+v6.2.1-beta (2018-07-17)
+-----------
+
+* Fixed `JsonObject` not inserting keys of type `String` (issue #782)
+
+v6.2.0-beta (2018-07-12)
+-----------
+
+* Disabled lazy number deserialization (issue #772)
+* Fixed `JsonVariant::is<int>()` that returned true for empty strings
+* Improved float serialization when `-fsingle-precision-constant` is used
+* Renamed function `RawJson()` to `serialized()`
+* `serializeMsgPack()` now supports values marked with `serialized()`
+
+> ### BREAKING CHANGES
+>
+> #### Non quoted strings
+>
+> Non quoted strings are now forbidden in values, but they are still allowed in keys.
+> For example, `{key:"value"}` is accepted, but `{key:value}` is not.
+>
+> #### Preformatted values
+>
+> Old code:
+>
+> ```c++
+> object["values"] = RawJson("[1,2,3,4]");
+> ```
+> 
+> New code:

+v6.1.0-beta (2018-07-02)
+-----------
+
+* 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;

+>   return;
+> }
+> ```

+
+v6.0.0-beta (2018-06-07)
+-----------
+
+* Added `DynamicJsonDocument` and `StaticJsonDocument`
