ArduinoJson: change log

HEAD

Made library easier to use from a CMake project: simply add_subdirectory(ArduinoJson/src)

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

Fixed segmentation fault in DynamicJsonBuffer when memory allocation fails (issue #92)

v4.5

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.

Special thanks to Giancarlo Canales Barreto for finding this nasty bug.

v4.4

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

v4.3

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)

v4.2

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

v4.1

Added DynamicJsonBuffer (issue #19)

v4.0

Unified parser and generator API (issue #23)
Updated library layout, now requires Arduino 1.0.6 or newer

BREAKING CHANGE: API changed significantly, see Migrating code to the new API.

v3.4

Fixed escaped char parsing (issue #16)

v3.3

Added indented output for the JSON generator (issue #11), see example bellow.
Added IndentedPrint, a decorator for Print to allow indented output

Example:

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

v3.2

Fixed a bug when adding nested object in JsonArray (bug introduced in v3.1).

v3.1

Calling Generator::JsonObject::add() twice with the same key now replaces the value
Added Generator::JsonObject::operator[], see bellow the new API
Added Generator::JsonObject::remove() (issue #9)

Old generator API:

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

Initial release
