 ArduinoJson: change log
 =======================
 
+v6.14.0 (2020-01-16)
+-------
+
+* Added `BasicJsonDocument::shrinkToFit()`
+* Added support of `uint8_t` for `serializeJson()`, `serializeJsonPretty()`, and `serializeMsgPack()` (issue #1142)
+* Added `ARDUINOJSON_ENABLE_COMMENTS` to enable support for comments (defaults to 0)
+* Auto enable support for `std::string` and `std::stream` on modern compilers (issue #1156)
+  (No need to define `ARDUINOJSON_ENABLE_STD_STRING` and `ARDUINOJSON_ENABLE_STD_STREAM` anymore)
+* Improved decoding of UTF-16 surrogate pairs (PR #1157 by @kaysievers)
+  (ArduinoJson now produces standard UTF-8 instead of CESU-8)
+* Added `measureJson`, `measureJsonPretty`, and `measureMsgPack` to `keywords.txt`
+  (This file is used for syntax highlighting in the Arduino IDE) 
+* Fixed `variant.is<nullptr_t>()`
+* Fixed value returned by `serializeJson()`, `serializeJsonPretty()`, and `serializeMsgPack()` when writing to a `String`
+* Improved speed of `serializeJson()`, `serializeJsonPretty()`, and `serializeMsgPack()` when writing to a `String`
+
+> ### BREAKING CHANGES
+> 
+> #### Comments
+> 
+> Support for comments in input is now optional and disabled by default.
+>
+> If you need support for comments, you must defined `ARDUINOJSON_ENABLE_COMMENTS` to `1`; otherwise, you'll receive `InvalidInput` errors.
+>
+> ```c++
+> #define ARDUINOJSON_ENABLE_COMMENTS 1
+> #include <ArduinoJson.h>
+> ```
+
+v6.13.0 (2019-11-01)
+-------
+
+* Added support for custom writer/reader classes (issue #1088)
+* Added conversion from `JsonArray` and `JsonObject` to `bool`, to be consistent with `JsonVariant`
+* Fixed `deserializeJson()` when input contains duplicate keys (issue #1095)
+* Improved `deserializeMsgPack()` speed by reading several bytes at once
+* Added detection of Atmel AVR8/GNU C Compiler (issue #1112)
+* Fixed deserializer that stopped reading at the first `0xFF` (PR #1118 by @mikee47)
+* Fixed dangling reference in copies of `MemberProxy` and `ElementProxy` (issue #1120)
+
+v6.12.0 (2019-09-05)
+-------
+
+* Use absolute instead of relative includes (issue #1072)
+* Changed `JsonVariant::as<bool>()` to return `true` for any non-null value (issue #1005)
+* Moved ancillary files to `extras/` (issue #1011)
+
+v6.11.5 (2019-08-23)
+-------
+
+* Added fallback implementations of `strlen_P()`, `strncmp_P()`, `strcmp_P()`, and `memcpy_P()` (issue #1073)
+
+v6.11.4 (2019-08-12)
+-------
+
+* Added `measureJson()` to the `ArduinoJson` namespace (PR #1069 by @nomis)
+* Added support for `basic_string<char, traits, allocator>` (issue #1045)
+* Fixed example `JsonConfigFile.ino` for ESP8266
+* Include `Arduino.h` if `ARDUINO` is defined (PR #1071 by @nomis)
+
+v6.11.3 (2019-07-22)
+-------
+
+* Added operators `==` and `!=` for `JsonDocument`, `ElementProxy`, and `MemberProxy`
+* Fixed comparison of `JsonVariant` when one contains a linked string and the other contains an owned string (issue #1051)
+
+v6.11.2 (2019-07-08)
+-------
+
+* Fixed assignment of `JsonDocument` to `JsonVariant` (issue #1023)
+* Fix invalid conversion error on Particle Argon (issue #1035)
+
+v6.11.1 (2019-06-21)
+-------
+
+* Fixed `serialized()` not working with Flash strings (issue #1030)
+
+v6.11.0 (2019-05-26)
+-------
+
+* Fixed `deserializeJson()` silently accepting a `Stream*` (issue #978)
+* Fixed invalid result from `operator|` (issue #981)
+* Made `deserializeJson()` more picky about trailing characters (issue #980)
+* Added `ARDUINOJSON_ENABLE_NAN` (default=0) to enable NaN in JSON (issue #973)
+* Added `ARDUINOJSON_ENABLE_INFINITY` (default=0) to enable Infinity in JSON
+* Removed implicit conversion in comparison operators (issue #998)
+* Added lexicographical comparison for `JsonVariant`
+* Added support for `nullptr` (issue #998)
+
+> ### BREAKING CHANGES
+> 
+> #### NaN and Infinity
+> 
+> The JSON specification allows neither NaN not Infinity, but previous
+> versions of ArduinoJson supported it. 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 <ArduinoJson.h>
+> ```
+> 
+> #### 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<float>())`.
