 ArduinoJson: change log
 =======================
 
+v6.0.1-beta
+-----------
+
+* Fixed conflicts with `isnan()` and `isinf()` macros (issue #752)
+
+v6.0.0-beta
+-----------
+
+* Added `DynamicJsonDocument` and `StaticJsonDocument`
+* Added `deserializeJson()`
+* Added `serializeJson()` and `serializeJsonPretty()`
+* Added `measureJson()` and `measureJsonPretty()`
+* Added `serializeMsgPack()`, `deserializeMsgPack()` and `measureMsgPack()` (issue #358)
+* Added example `MsgPackParser.ino` (issue #358)
+* Added support for non zero-terminated strings (issue #704)
+* Removed `JsonBuffer::parseArray()`, `parseObject()` and `parse()`
+* Removed `JsonBuffer::createArray()` and `createObject()`
+* Removed `printTo()` and `prettyPrintTo()`
+* Removed `measureLength()` and `measurePrettyLength()`
+* Removed all deprecated features
+
+> ### BREAKING CHANGES
+> 
+> #### Deserialization
+> 
+> Old code:
+> 
+> ```c++
+> DynamicJsonBuffer jb;
+> JsonObject& obj = jb.parseObject(json);
+> if (obj.success()) {
+> 
+> }
+> ```
+> 
+> New code:
+> 
+> ```c++
+> DynamicJsonDocument doc;
+> DeserializationError error = deserializeJson(doc, json);
+> if (error) {
+> 
+> }
+> JsonObject& obj = doc.as<JsonObject>();
+> ```
+> 
+> #### Serialization
+> 
+> Old code:

+> DynamicJsonBuffer jb;
+> JsonObject& obj = jb.createObject();
+> obj["key"] = "value";
+> obj.printTo(Serial);

+> ```c++
+> DynamicJsonDocument obj;
+> JsonObject& obj = doc.to<JsonObject>();

+> ```
+
+v5.13.2
+-------
+
+* Fixed `JsonBuffer::parse()` not respecting nesting limit correctly (issue #693)
+* Fixed inconsistencies in nesting level counting (PR #695 from Zhenyu Wu)
+* Fixed null values that could be pass to `strcmp()` (PR #745 from Mike Karlesky)
+* Added macros `ARDUINOJSON_VERSION`, `ARDUINOJSON_VERSION_MAJOR`...
+
+v5.13.1
+-------
+
+* Fixed `JsonVariant::operator|(int)` that returned the default value if the variant contained a double (issue #675)
+* Allowed non-quoted key to contain underscores (issue #665)
+
+v5.13.0
+-------
+
+* Changed the rules of string duplication (issue #658)
+* `RawJson()` accepts any kind of string and obeys to the same rules for duplication
+* Changed the return type of `strdup()` to `const char*` to prevent double duplication
+* Marked `strdup()` as deprecated
+
+> ### New rules for string duplication
+>
+> | type                       | duplication |
+> |:---------------------------|:------------|
+> | const char*                | no          |
+> | char*                      | ~~no~~ yes  |
+> | String                     | yes         |
+> | std::string                | yes         |
+> | const __FlashStringHelper* | yes         |
+>
+> These new rules make `JsonBuffer::strdup()` useless.
+
+v5.12.0
+-------
+
+* Added `JsonVariant::operator|` to return a default value (see below)
+* Added a clear error message when compiled as C instead of C++ (issue #629)
+* Added detection of MPLAB XC compiler (issue #629)
+* Added detection of Keil ARM Compiler (issue #629)
+* Added an example that shows how to save and load a configuration file
+* Reworked all other examples
+
+> ### How to use the new feature?
+>
+> If you have a block like this:
+>
+> ```c++
+> const char* ssid = root["ssid"];
+> if (!ssid)
+>   ssid = "default ssid";
+> ```
+>
+> You can simplify like that:
+>
+> ```c++
+> const char* ssid = root["ssid"] | "default ssid";
+> ```
+
+v5.11.2
+-------
+
+* Fixed `DynamicJsonBuffer::clear()` not resetting allocation size (issue #561)
+* Fixed incorrect rounding for float values (issue #588)
+
+v5.11.1
+-------
+
+* Removed dependency on `PGM_P` as Particle 0.6.2 doesn't define it (issue #546)
+* Fixed warning "dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]"
+* Fixed warning "floating constant exceeds range of 'float' [-Woverflow]" (issue #544)
+* Fixed warning "this statement may fall through" [-Wimplicit-fallthrough=] (issue #539)
+* Removed `ARDUINOJSON_DOUBLE_IS_64BITS` as it became useless.

 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!

-*An elegant and efficient JSON library for embedded systems.*
+ArduinoJson is a C++ JSON library for Arduino and IoT (Internet Of Things).
 
-It's designed to have the most intuitive API, the smallest footprint and is able to work without any allocation on the heap (no malloc).
-
-It has been written with Arduino in mind, but it isn't linked to Arduino libraries so you can use this library in any other C++ project.
-For instance, it supports Aduino's `String` and `Stream`, but also `std::string`, `std::istream` and `std::ostream`.
