    🚀 Changes since 6.10.0

    • 🛠 Fixed error "attributes are not allowed on a function-definition"

    How to install

    There are several ways to install ArduinoJson, from simpler to more complex:

    1. Use the Arduino Library Manager
    2. Download ArduinoJson-v6.10.1.h put it in your project folder
    3. Download ArduinoJson-v6.10.1.zip and extract it in you libraries folder

    Note: ArduinoJson-v6.10.1.h are ArduinoJson-v6.10.1.hpp are almost identical; the difference is that the .hpp keeps everything in the ArduinoJson namespace.

    🍱 Special note ⚠️

    ⚡️ ArduinoJson 6 requires updating code written for version 5.
    See the migration guide for details.

    🚀 Changes since 6.9.1

    • 🛠 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()

      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:

    DynamicJsonDocument doc;

    New code:

    DynamicJsonDocument doc(1024);

    Nesting limit

    JsonDocument::nestingLimit was replaced with a new parameter to deserializeJson() and deserializeMsgPack().

    Old code:

    doc.nestingLimit = 15;deserializeJson(doc, input);

    New code:

    deserializeJson(doc, input, DeserializationOption::NestingLimit(15));
