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 > ``` > > #### 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())`. v6.10.1 (2019-04-23) ------- * Fixed error "attributes are not allowed on a function-definition" * Fixed `deserializeJson()` not being picky enough (issue #969) * Fixed error "no matching function for call to write(uint8_t)" (issue #972) v6.10.0 (2019-03-22) ------- * Fixed an integer overflow in the JSON deserializer * Added overflow handling in `JsonVariant::as()` and `JsonVariant::is()`. - `as()` returns `0` if the integer `T` overflows - `is()` returns `false` if the integer `T` overflows * Added `BasicJsonDocument` to support custom allocator (issue #876) * Added `JsonDocument::containsKey()` (issue #938) * Added `JsonVariant::containsKey()` v6.9.1 (2019-03-01) ------ * Fixed warning "unused variable" with GCC 4.4 (issue #912) * Fixed warning "cast increases required alignment" (issue #914) * Fixed warning "conversion may alter value" (issue #914) * Fixed naming conflict with "CAPACITY" (issue #839) * Muted warning "will change in GCC 7.1" (issue #914) * Added a clear error message for `StaticJsonBuffer` and `DynamicJsonBuffer` * Marked ArduinoJson.h as a "system header" v6.9.0 (2019-02-26) ------ * Decode escaped Unicode characters like \u00DE (issue #304, PR #791) Many thanks to Daniel Schulte (aka @trilader) who implemented this feature. * Added option ARDUINOJSON_DECODE_UNICODE to enable it * Converted `JsonArray::copyFrom()/copyTo()` to free functions `copyArray()` * Renamed `JsonArray::copyFrom()` and `JsonObject::copyFrom()` to `set()` * Renamed `JsonArray::get()` to `getElement()` * Renamed `JsonArray::add()` (without arg) to `addElement()` * Renamed `JsonObject::get()` to `getMember()` * Renamed `JsonObject::getOrCreate()` to `getOrAddMember()` * Fixed `JsonVariant::isNull()` not returning `true` after `set((char*)0)` * Fixed segfault after `variant.set(serialized((char*)0))` * Detect `IncompleteInput` in `false`, `true`, and `null` * Added `JsonDocument::size()` * Added `JsonDocument::remove()` * Added `JsonVariant::clear()` * Added `JsonVariant::remove()` v6.8.0-beta (2019-01-30) ----------- * Import functions in the ArduinoJson namespace to get clearer errors * Improved syntax highlighting in Arduino IDE * Removed default capacity of `DynamicJsonDocument` * `JsonArray::copyFrom()` accepts `JsonArrayConst` * `JsonVariant::set()` accepts `JsonArrayConst` and `JsonObjectConst` * `JsonDocument` was missing in the ArduinoJson namespace * Added `memoryUsage()` to `JsonArray`, `JsonObject`, and `JsonVariant` * Added `nesting()` to `JsonArray`, `JsonDocument`, `JsonObject`, and `JsonVariant` * Replaced `JsonDocument::nestingLimit` with an additional parameter to `deserializeJson()` and `deserializeMsgPack()` * Fixed uninitialized variant in `JsonDocument` * Fixed `StaticJsonDocument` copy constructor and copy assignment * The copy constructor of `DynamicJsonDocument` chooses the capacity according to the memory usage of the source, not from the capacity of the source. * Added the ability to create/assign a `StaticJsonDocument`/`DynamicJsonDocument` from a `JsonArray`/`JsonObject`/`JsonVariant` * Added `JsonDocument::isNull()` * Added `JsonDocument::operator[]` * Added `ARDUINOJSON_TAB` to configure the indentation character * Reduced the size of the pretty JSON serializer * Added `add()`, `createNestedArray()` and `createNestedObject()` to `JsonVariant` * `JsonVariant` automatically promotes to `JsonObject` or `JsonArray` on write.
