ArduinoJson 4.5

Changes since v4.4

• 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.

The documentation is in the wiki.

ArduinoJson 5.0 beta 1

Changes since v4.4

• Added support of String class (issue #55, #56, #70, #77)
• Redesigned JsonVariant to leverage converting constructors instead of assignment operators
• Switched to new 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 predicatable.
You certainly don't want that in an embedded environment!

CAUTION: the documentation on the wiki hasn't been updated yet.

ArduinoJson 4.4

Changes since v4.3

• Added JsonArray::measureLength() and JsonObject::measureLength() (issue #75)

The documentation is in the wiki.

ArduinoJson 4.3

Changes since v4.2

• 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)

The documentation is in the wiki.

ArduinoJson 4.2

Changes since v4.1

• 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

The documentation is in the wiki.

ArduinoJson 3.3

Changes compared to 3.2:

• Added indented output for the JSON generator, see example bellow.
• Added IndentedPrint, a decorator for Print to allow indented output

Example:

JsonOject<2> json;
json["key"] = "value";
json.prettyPrintTo(Serial);
