ArduinoJson: change log
=======================
HEAD
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
----
* Optimize storage of static strings
* Fixed segmentation fault in `DynamicJsonBuffer` when memory allocation fails (issue #92)
> ### BREAKING CHANGES
>
> Static string cannot contain NUL characters anymore (they could since 7.3.0).
> This is an extremely rare case, so you probably won't be affected.
>
> For example, the following code produces different output in 7.3 and 7.4:
>
> ```cpp
> JsonDocument doc;
> doc["a\0b"] = "c\0d";
> serializeJson(doc, Serial);
> // With Arduino 7.3 -> {"a\u0000b":"c\u0000d"}
> // With Arduino 7.4 -> {"a":"c"}
> ```
>
> `JsonString` contructor now only accepts two arguments, not three.
> If your code uses `JsonString` to store a string as a pointer, you must remove the size argument.
>
> For example, if you have something like this:
>
> ```cpp
> doc["key"] = JsonString(str.c_str(), str.size(), true);
> ```
>
> You must replace with either:
>
> ```cpp
> doc["key"] = JsonString(str.c_str(), true); // store as pointer, cannot contain NUL characters
> doc["key"] = JsonString(str.c_str(), str.size()); // store by copy, NUL characters allowed
> doc["key"] = str; // same as previous line for supported string classes (`String`, `std::string`, etc.)
> ```
v4.5
----
v7.4.1 (2025-04-11)
------
* Fixed buffer overflow when input contains a backslash followed by a terminator (issue #81)
* Fix crash with tiny Flash strings (issue #2170)
**Upgrading is recommended** since previous versions contain a potential security risk.
v7.4.0 (2025-04-09)
------
Special thanks to [Giancarlo Canales Barreto](https://github.com/gcanalesb) for finding this nasty bug.
* Optimize storage of tiny strings (up to 3 characters)
* Fix support for `const char[]` (issue #2166)
v4.4
----
v7.3.1 (2025-02-27)
------
* Added `JsonArray::measureLength()` and `JsonObject::measureLength()` (issue #75)
* Fix conversion from static string to number
* Slightly reduce code size
v4.3
----
v7.3.0 (2024-12-29)
------
* 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)
* Fix support for NUL characters in `deserializeJson()`
* Make `ElementProxy` and `MemberProxy` non-copyable
* Change string copy policy: only string literal are stored by pointer
* `JsonString` is now stored by copy, unless specified otherwise
* Replace undocumented `JsonString::Ownership` with `bool`
* Rename undocumented `JsonString::isLinked()` to `isStatic()`
* Move public facing SFINAEs to template declarations
v4.2
----
> ### BREAKING CHANGES
>
> In previous versions, `MemberProxy` (the class returned by `operator[]`) could lead to dangling pointers when used with a temporary string.
> To prevent this issue, `MemberProxy` and `ElementProxy` are now non-copyable.
>
> Your code is likely to be affected if you use `auto` to store the result of `operator[]`. For example, the following line won't compile anymore:
>
> ```cpp
> auto value = doc["key"];
> ```
>
> To fix the issue, you must append either `.as<T>()` or `.to<T>()`, depending on the situation.
>
> For example, if you are extracting values from a JSON document, you should update like this:
>
> ```diff
> - auto config = doc["config"];
> + auto config = doc["config"].as<JsonObject>();
> const char* name = config["name"];
> ```
>
> However, if you are building a JSON document, you should update like this:
>
> ```diff
> - auto config = doc["config"];
> + auto config = doc["config"].to<JsonObject>();
> config["name"] = "ArduinoJson";
> ```
* 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
v7.2.1 (2024-11-15)
------
v4.1
----
* Forbid `deserializeJson(JsonArray|JsonObject, ...)` (issue #2135)
* Fix VLA support in `JsonDocument::set()`
* Fix `operator[](variant)` ignoring NUL characters
* Added DynamicJsonBuffer (issue #19)
v7.2.0 (2024-09-18)
------
v4.0
----
* Store object members with two slots: one for the key and one for the value
* Store 64-bit numbers (`double` and `long long`) in an additional slot
* Reduce the slot size (see table below)
* Improve message when user forgets third arg of `serializeJson()` et al.
* Set `ARDUINOJSON_USE_DOUBLE` to `0` by default on 8-bit architectures
* Deprecate `containsKey()` in favor of `doc["key"].is<T>()`
* Add support for escape sequence `\'` (issue #2124)
* Unified parser and generator API (issue #23)
* Updated library layout, now requires Arduino 1.0.6 or newer
| Architecture | before | after |
|--------------|----------|----------|
| 8-bit | 8 bytes | 6 bytes |
| 32-bit | 16 bytes | 8 bytes |
| 64-bit | 24 bytes | 16 bytes |
**BREAKING CHANGE**: API changed significantly, see [Migrating code to the new API](https://github.com/bblanchon/ArduinoJson/wiki/Migrating-code-to-the-new-API).
> ### BREAKING CHANGES
>
> After being on the death row for years, the `containsKey()` method has finally been deprecated.
> You should replace `doc.containsKey("key")` with `doc["key"].is<T>()`, which not only checks that the key exists but also that the value is of the expected type.
>
> ```cpp
> // Before
> if (doc.containsKey("value")) {
> int value = doc["value"];
> // ...
> }
>
> // After
> if (doc["value"].is<int>()) {
> int value = doc["value"];
> // ...
> }
> ```
v7.1.0 (2024-06-27)
------
v3.4
----
* Add `ARDUINOJSON_STRING_LENGTH_SIZE` to the namespace name
* Add support for MsgPack binary (PR #2078 by @Sanae6)
* Add support for MsgPack extension
* Make string support even more generic (PR #2084 by @d-a-v)
* Optimize `deserializeMsgPack()`
* Allow using a `JsonVariant` as a key or index (issue #2080)
Note: works only for reading, not for writing
* Support `ElementProxy` and `MemberProxy` in `JsonDocument`'s constructor
* Don't add partial objects when allocation fails (issue #2081)
* Read MsgPack's 64-bit integers even if `ARDUINOJSON_USE_LONG_LONG` is `0`
(they are set to `null` if they don't fit in a `long`)
* Fixed escaped char parsing (issue #16)
v7.0.4 (2024-03-12)
------
* Make `JSON_STRING_SIZE(N)` return `N+1` to fix third-party code (issue #2054)
v3.3
----

Old generator API:
> ### 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.
>
> ```c++
> // ArduinoJson 6
> StaticJsonDocument<256> doc;
> // or
> DynamicJsonDocument doc(256);
>
> // ArduinoJson 7
> JsonDocument doc;
> ```
>
> In ArduinoJson 7, `JsonDocument` reuses released memory, so `garbageCollect()` has been removed.
> `shrinkToFit()` is still available and releases the over-allocated memory.
>
> 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.
>
> 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.
>
> #### 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`.
>
> ```c++
> // ArduinoJson 6
> class MyAllocator {
> // ...
> };
> BasicJsonDocument<MyAllocator> doc(256);
>
> // ArduinoJson 7
> class MyAllocator : public ArduinoJson::Allocator {
> // ...
> };
> MyAllocator myAllocator;
> JsonDocument doc(&myAllocator);
> ```
>
> #### `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:
>
> ```c++
> // ArduinoJson 6
> arr.createNestedArray();
> arr.createNestedObject();
>
> // ArduinoJson 7
> arr.add<JsonArray>();
> arr.add<JsonObject>();
> ```
>
> And to create `{"array":[],"object":{}}`, you would write:
>
> ```c++
> // ArduinoJson 6
> obj.createNestedArray("array");
> obj.createNestedObject("object");
>
> // ArduinoJson 7
> obj["array"].to<JsonArray>();
> obj["object"].to<JsonObject>();
> ```
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 case `#include "jsmn.cpp"` which caused an error in Linux (issue #6)
* Fixed a buffer overrun in JSON Parser (issue #5)
v2.0
----
* Added JSON encoding (issue #2)
* Renamed the library `ArduinoJsonParser` becomes `ArduinoJson`
**Breaking change**: you need to add the following line at the top of your program.
using namespace ArduinoJson::Parser;
v1.2
----
* Fixed error in JSON parser example (issue #1)
v1.1
----
* 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
v1.0
----

```c++
const char* json = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
JsonDocument doc;
deserializeJson(doc, json);
StaticJsonBuffer<200> jsonBuffer;
const char* sensor = doc["sensor"];
long time = doc["time"];
double latitude = doc["data"][0];
double longitude = doc["data"][1];
JsonObject& root = jsonBuffer.parseObject(json);
const char* sensor = root["sensor"];
long time = root["time"];
double latitude = root["data"][0];
double longitude = root["data"][1];
```
See the [tutorial on arduinojson.org](https://arduinojson.org/v7/doc/deserialization/)
### Serialization
Here is a program that generates a JSON document with ArduinoJson:
#### Encoding / Generating
```c++
JsonDocument doc;
StaticJsonBuffer<200> jsonBuffer;
doc["sensor"] = "gps";
doc["time"] = 1351824120;
doc["data"][0] = 48.756080;
doc["data"][1] = 2.302038;
JsonObject& root = jsonBuffer.createObject();
root["sensor"] = "gps";
root["time"] = 1351824120;
serializeJson(doc, Serial);
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
root.printTo(Serial);
// This prints:
// {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}
```

Testimonials
------------
If you run a commercial project that embeds ArduinoJson, think about [sponsoring the library's development](https://github.com/sponsors/bblanchon): it ensures the code that your products rely on stays actively maintained. It can also give your project some exposure to the makers' community.
From Arduino's Forum user `jflaplante`:
> I tried aJson 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.
If you are an individual user and want to support the development (or give a sign of appreciation), consider purchasing the book [Mastering ArduinoJson](https://arduinojson.org/book/)&nbsp;❤, or simply [cast a star](https://github.com/bblanchon/ArduinoJson/stargazers)&nbsp;⭐.
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.
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.
From GitHub user `zacsketches`:
> Thanks for a great library!!!
> I've been watching you consistently develop this library over the past six months, and I used it today for a publish and subscribe architecture designed to help hobbyists move into more advanced robotics. Your library allowed me to implement remote subscription in order to facilitate multi-processor robots.
> ArduinoJson saved me a week's worth of time!!
[From Reddit user `erm_what_`](https://www.reddit.com/r/arduino/comments/3jj6ep/announcing_arduinojson_50/cusjk8c):
> This is a great library and I wouldn't be able to do the project I'm doing without it. I completely recommend it.
[From Reddit user `makerhacks`](https://www.reddit.com/r/arduino/comments/3jj6ep/announcing_arduinojson_50/cusqg7b):
> I am just starting an ESP8266 clock project and now I can output JSON from my server script and interpret it painlessly.
