2023-02-17 - 2023-03-03

	- huge code review, many changes to improve stability
	- basic multilanguage support (pre-compile option)
		- all strings used in program moved to header files and stored in progmem
	- nearly all modules/features are now pre-compile configurable via settings.h and/or build flags
	- move sensors configuration out of thermostat configuration as it will also be used in other firmware variants
	- firmware variant HEATCONTROL code complete and well tested (currently only language version DE is fully implemented)
	- firmware variant THERMOSTAT taken over from WiFiThermostat but not yet finished
	- other firmware variants as "WiFiBlinds" (UART to MQTT bridge) not yet implemented

2023-02-17
	- update arduinoWebSockets-2.1.4 -> arduinoWebSockets-2.3.6
	##- update DHT-sensor-library-1.3.8 -> DHT-sensor-library-1.4.4
	##- update Adafruit_Sensor-1.1.1 -> Adafruit_Sensor-1.1.7 (previously unused? necessary for DHT-sensor-library-1.3.8)
	##  --> reverted as often could not read DHT sensor with it. did not investigate why.
	- update ArduinoJson-6.13.0 -> ArduinoJson-6.20.1
	- update pubsubclient-2.7 -> pubsubclient-2.8
	- update Bounce2-2.52 -> Bounce2-2.71
	- building with ESP8266 Arduino Core v3.0.2 works now (but not tested much yet)
	- building with ESP8266 Arduino Core v3.1.1 works now (but not tested much yet)
	- FS: replaced deprecated SPIFFS with LittleFS
	- config: complete rework - now saves binary structs instead of overly complicated to maintain json files to file system
	- config: move secrets to its own struct, which is saved to "EEPROM" instead of file system to make extracting passwords much harder
	- config: improve XOR encryption of secrets

2023-02-01
	- started "universal" base firmware using code base of WiFiThermostat v0.7.1
	- merged with WiFiBlinds dev version (also initially starting from WiFiThermostat) which already had many improvements
	- make firmware variant configurable by pre-compile config switches

+# Adafruit Unified Sensor Driver #
+
+Many small embedded systems exist to collect data from sensors, analyse the data, and either take an appropriate action or send that sensor data to another system for processing.
+
+One of the many challenges of embedded systems design is the fact that parts you used today may be out of production tomorrow, or system requirements may change and you may need to choose a different sensor down the road.
+
+Creating new drivers is a relatively easy task, but integrating them into existing systems is both error prone and time consuming since sensors rarely use the exact same units of measurement.
+
+By reducing all data to a single **sensors\_event\_t** 'type' and settling on specific, **standardised SI units** for each sensor family the same sensor types return values that are comparable with any other similar sensor.  This enables you to switch sensor models with very little impact on the rest of the system, which can help mitigate some of the risks and problems of sensor availability and code reuse.
+
+The unified sensor abstraction layer is also useful for data-logging and data-transmission since you only have one well-known type to log or transmit over the air or wire.
+

+
+
+## How Does it Work? ##
+
+Any driver that supports the Adafruit unified sensor abstraction layer will implement the Adafruit\_Sensor base class.  There are two main typedefs and one enum defined in Adafruit_Sensor.h that are used to 'abstract' away the sensor details and values:
+
+## Sensor Types (`sensors_type_t`)
+
+These pre-defined sensor types are used to properly handle the two related typedefs below, and allows us determine what types of units the sensor uses, etc.
+
+```c++
+/** Sensor types */
+typedef enum
+{
+  SENSOR_TYPE_ACCELEROMETER         = (1),
+  SENSOR_TYPE_MAGNETIC_FIELD        = (2),
+  SENSOR_TYPE_ORIENTATION           = (3),
+  SENSOR_TYPE_GYROSCOPE             = (4),
+  SENSOR_TYPE_LIGHT                 = (5),
+  SENSOR_TYPE_PRESSURE              = (6),
+  SENSOR_TYPE_PROXIMITY             = (8),
+  SENSOR_TYPE_GRAVITY               = (9),
+  SENSOR_TYPE_LINEAR_ACCELERATION   = (10),
+  SENSOR_TYPE_ROTATION_VECTOR       = (11),
+  SENSOR_TYPE_RELATIVE_HUMIDITY     = (12),
+  SENSOR_TYPE_AMBIENT_TEMPERATURE   = (13),
+  SENSOR_TYPE_VOLTAGE               = (15),
+  SENSOR_TYPE_CURRENT               = (16),
+  SENSOR_TYPE_COLOR                 = (17),
+  SENSOR_TYPE_TVOC                  = (18),
+  SENSOR_TYPE_VOC_INDEX             = (19),
+  SENSOR_TYPE_NOX_INDEX             = (20)
+} sensors_type_t;
+```
+
+## Sensor Details (`sensor_t`)
+
+This typedef describes the specific capabilities of this sensor, and allows us to know what sensor we are using beneath the abstraction layer.
+
+```c++
+/* Sensor details (40 bytes) */
+/** struct sensor_s is used to describe basic information about a specific sensor. */
+typedef struct
+{
+    char     name[12];
+    int32_t  version;
+    int32_t  sensor_id;
+    int32_t  type;
+    float    max_value;
+    float    min_value;
+    float    resolution;
+    int32_t  min_delay;
+} sensor_t;
+```
+
+The individual fields are intended to be used as follows:
+
+- **name**: The sensor name or ID, up to a maximum of twelve characters (ex. "MPL115A2")
+- **version**: The version of the sensor HW and the driver to allow us to differentiate versions of the board or driver
+- **sensor\_id**: A unique sensor identifier that is used to differentiate this specific sensor instance from any others that are present on the system or in the sensor network
+- **type**: The sensor type, based on **sensors\_type\_t** in sensors.h
+- **max\_value**: The maximum value that this sensor can return (in the appropriate SI unit)
+- **min\_value**: The minimum value that this sensor can return (in the appropriate SI unit)
+- **resolution**: The smallest difference between two values that this sensor can report (in the appropriate SI unit)
+- **min\_delay**: The minimum delay in microseconds between two sensor events, or '0' if there is no constant sensor rate
+
+## Sensor Data/Events (`sensors_event_t`)
+
+This typedef is used to return sensor data from any sensor supported by the abstraction layer, using standard SI units and scales.
+
+```c++
+/* Sensor event (36 bytes) */
+/** struct sensor_event_s is used to provide a single sensor event in a common format. */
+typedef struct
+{
+    int32_t version;
+    int32_t sensor_id;
+    int32_t type;
+    int32_t reserved0;
+    int32_t timestamp;
+    union
+    {
+        float           data[4];
+        sensors_vec_t   acceleration;
+        sensors_vec_t   magnetic;
+        sensors_vec_t   orientation;
+        sensors_vec_t   gyro;
+        float           temperature;
+        float           distance;
+        float           light;
+        float           pressure;
+        float           relative_humidity;
+        float           current;
+        float           voltage;
+        float           tvoc;
+        float           voc_index;
+        float           nox_index;
+        sensors_color_t color;
+    };
+} sensors_event_t;
+```
+It includes the following fields:
+
+- **version**: Contain 'sizeof(sensors\_event\_t)' to identify which version of the API we're using in case this changes in the future
+- **sensor\_id**: A unique sensor identifier that is used to differentiate this specific sensor instance from any others that are present on the system or in the sensor network (must match the sensor\_id value in the corresponding sensor\_t enum above!)
+- **type**: the sensor type, based on **sensors\_type\_t** in sensors.h
+- **timestamp**: time in milliseconds when the sensor value was read
+- **data[4]**: An array of four 32-bit values that allows us to encapsulate any type of sensor data via a simple union (further described below)
+
+## Required Functions
+
+In addition to the two standard types and the sensor type enum, all drivers based on Adafruit_Sensor must also implement the following two functions:
+
+```c++
+bool getEvent(sensors_event_t*);
+```
+Calling this function will populate the supplied sensors\_event\_t reference with the latest available sensor data.  You should call this function as often as you want to update your data.
+
+```c++
+void getSensor(sensor_t*);
+```
+Calling this function will provide some basic information about the sensor (the sensor name, driver version, min and max values, etc.
+
+## Standardised SI values for `sensors_event_t`
+
+A key part of the abstraction layer is the standardisation of values on SI units of a particular scale, which is accomplished via the data[4] union in sensors\_event\_t above.  This 16 byte union includes fields for each main sensor type, and uses the following SI units and scales:
+
+- **acceleration**: values are in **meter per second per second** (m/s^2)
+- **magnetic**: values are in **micro-Tesla** (uT)
+- **orientation**: values are in **degrees**
+- **gyro**: values are in **rad/s**
+- **temperature**: values in **degrees centigrade** (Celsius) 
+- **distance**: values are in **centimeters**
+- **light**: values are in **SI lux** units
+- **pressure**: values are in **hectopascal** (hPa)
+- **relative\_humidity**: values are in **percent**
+- **current**: values are in **milliamps** (mA)
+- **voltage**: values are in **volts** (V)
+- **color**: values are in 0..1.0 RGB channel luminosity and 32-bit RGBA format
+- **tvoc**: values are in **parts per billion** (ppb)
+- **voc_index**: values are an **index** from 1-500 with 100 being normal
+- **nox_index**: values are an **index** from 1-500 with 100 being normal
+
+
+## The Unified Driver Abstraction Layer in Practice ##
+
+Using the unified sensor abstraction layer is relatively easy once a compliant driver has been created.
+
+Every compliant sensor can now be read using a single, well-known 'type' (sensors\_event\_t), and there is a standardised way of interrogating a sensor about its specific capabilities (via sensor\_t).
+
+An example of reading the [TSL2561](https://github.com/adafruit/Adafruit_TSL2561) light sensor can be seen below:
+
+```c++
+ Adafruit_TSL2561 tsl = Adafruit_TSL2561(TSL2561_ADDR_FLOAT, 12345);
+ ...
+ /* Get a new sensor event */ 
+ sensors_event_t event;
+ tsl.getEvent(&event);
+ 
+ /* Display the results (light is measured in lux) */
+ if (event.light)
+ {
+   Serial.print(event.light); Serial.println(" lux");
+ }
+ else
+ {
+   /* If event.light = 0 lux the sensor is probably saturated
+      and no reliable data could be generated! */
+   Serial.println("Sensor overload");
+ }
+```
+
+Similarly, we can get the basic technical capabilities of this sensor with the following code:
+
+```c++
+ sensor_t sensor;
+ 
+ sensor_t sensor;
+ tsl.getSensor(&sensor);
+
+ /* Display the sensor details */
+ Serial.println("------------------------------------");
+ Serial.print  ("Sensor:       "); Serial.println(sensor.name);
+ Serial.print  ("Driver Ver:   "); Serial.println(sensor.version);
+ Serial.print  ("Unique ID:    "); Serial.println(sensor.sensor_id);
+ Serial.print  ("Max Value:    "); Serial.print(sensor.max_value); Serial.println(" lux");
+ Serial.print  ("Min Value:    "); Serial.print(sensor.min_value); Serial.println(" lux");
+ Serial.print  ("Resolution:   "); Serial.print(sensor.resolution); Serial.println(" lux");  
+ Serial.println("------------------------------------");
+ Serial.println("");
+```

+
+You will need a pull-up resistor of about 5 KOhm between the 1-Wire data line
+and your 5V power. If you are using the DS18B20, ground pins 1 and 3. The
+centre pin is the data line '1-wire'.
+
+In case of temperature conversion problems (result is `-85`), strong pull-up setup may be necessary. See section 
+_Powering the DS18B20_ in 
+[DS18B20 datasheet](https://datasheets.maximintegrated.com/en/ds/DS18B20.pdf) (page 7)
+and use `DallasTemperature(OneWire*, uint8_t)` constructor.
+
+We have included a "REQUIRESNEW" and "REQUIRESALARMS" definition. If you 
+want to slim down the code feel free to use either of these by including
+
+
+
+	#define REQUIRESNEW 
+
+or 
+
+	#define REQUIRESALARMS
+
+
+at the top of DallasTemperature.h
+
+Finally, please include OneWire from Paul Stoffregen in the library manager before you begin.
+
+## Credits
+
+The OneWire code has been derived from
+http://www.arduino.cc/playground/Learning/OneWire.
+Miles Burton <miles@mnetcs.com> originally developed this library.
+Tim Newsome <nuisance@casualhacker.net> added support for multiple sensors on
+the same bus.
+Guil Barros [gfbarros@bappos.com] added getTempByAddress (v3.5)
+   Note: these are implemented as getTempC(address) and getTempF(address)
+Rob Tillaart [rob.tillaart@gmail.com] added async modus (v3.7.0)

+ArduinoJson: change log
+=======================
+
+v6.20.1 (2023-02-08)
+-------
+
+* Remove explicit exclusion of `as<char*>()` and `as<char>()` (issue #1860)
+  If you try to call them, you'll now get the same error message as any unsupported type.
+  You could also add a custom converter for `char*` and `char`.
+
+v6.20.0 (2022-12-26)
+-------
+
+* Add `JsonVariant::shallowCopy()` (issue #1343)
+* Fix `9.22337e+18 is outside the range of representable values of type 'long'`
+* Fix comparison operators for `JsonArray`, `JsonArrayConst`, `JsonObject`, and `JsonObjectConst`
+* Fix lax parsing of `true`, `false`, and `null` (issue #1781)
+* Remove undocumented `accept()` functions
+* Rename `addElement()` to `add()`
+* Remove `getElement()`, `getOrAddElement()`, `getMember()`, and `getOrAddMember()`
+* Remove undocumented `JsonDocument::data()` and `JsonDocument::memoryPool()`
+* Remove undocumented `JsonArrayIterator::internal()` and `JsonObjectIterator::internal()`
+* Rename things in `ARDUINOJSON_NAMESPACE` to match the public names
+* Add documentation to most public symbols
+* Remove support for naked `char` (was deprecated since 6.18.0)
+
+> ### BREAKING CHANGES
+>
+> This release hides `JsonVariant`'s functions that were only intended for internal use.
+> If you were using them in your programs, you must replace with `operator[]` and `to<JsonVariant>()`, like so:
+>
+> ```c++
+> // before
+> JsonVariant a = variant.getElement(idx);
+> JsonVariant b = variant.getOrAddElement(idx);
+> JsonVariant c = variant.getMember(key);
+> JsonVariant d = variant.getOrAddMember(key);
+>
+> // after
+> JsonVariant a = variant[idx];
+> JsonVariant b = idx < variant.size() ? variant[idx] : variant[idx].to<JsonVariant>();
+> JsonVariant c = variant[key];
+> JsonVariant d = variant.containsKey(key) ? variant[key] : variant[key].to<JsonVariant>();
+> ```
+
+v6.19.4 (2022-04-05)

+* Fix `JsonString` operator `==` and `!=` for non-zero-terminated string
+* Fix `-Wsign-conversion` on GCC 8 (issue #1715)

+
+v6.19.1 (2022-01-14)
+-------
+
+* Fix crash when adding an object member in a too small `JsonDocument`
+* Fix filter not working in zero-copy mode (issue #1697)
+
+v6.19.0 (2022-01-08)
+-------
+
+* Remove `ARDUINOJSON_EMBEDDED_MODE` and assume we run on an embedded platform.  
+  Dependent settings (like `ARDUINOJSON_DEFAULT_NESTING_LIMIT`) must be set individually.
+* Change the default of `ARDUINOJSON_USE_DOUBLE` to `1`
+* Change the default of `ARDUINOJSON_USE_LONG_LONG` to `1` on 32-bit platforms
+* Add `as<JsonString>()` and `is<JsonString>()`
+* Add safe bool idiom in `JsonString`
+* Add support for NUL in string values (issue #1646)
+* Add support for arbitrary array rank in `copyArray()`
+* Add support for `char[][]` in `copyArray()`

+* Fix inconsistent pool capacity between `BasicJsonDocument`'s copy and move constructors
+* Fix inconsistent pool capacity between `BasicJsonDocument`'s copy and move assignments
+* Fix return type of `StaticJsonDocument::operator=`
+* Avoid pool reallocation in `BasicJsonDocument`'s copy assignment if capacity is the same
+* Avoid including `Arduino.h` when all its features are disabled (issue #1692, PR #1693 by @paulocsanz)
+* Assume `PROGMEM` is available as soon as `ARDUINO` is defined (consequence of #1693)
+

+* PlatformIO: set `build.libArchive` to `false` (PR #1550 by @askreet)
+
+> ### BREAKING CHANGES
+>
+> #### Support for `char` removed
+>
+> We cannot cast a `JsonVariant` to a `char` anymore, so the following will break:
+> ```c++
+> char age = doc["age"];  //  error: no matching function for call to 'variantAs(VariantData*&)'
+> ```
+> Instead, you must use another integral type, such as `int8_t`:
+> ```c++
+> int8_t age = doc["age"];  // OK
+> ```
+>
+> Similarly, we cannot assign from a `char` anymore, so the following will break:
+> ```c++
+> char age;
+> doc["age"] = age;  // error: no matching function for call to 'VariantRef::set(const char&)'
+> ```
+> Instead, you must use another integral type, such as `int8_t`:
+> ```c++
+> int8_t age;
+> doc["age"] = age;  // OK
+> ```
+> A deprecation warning with the message "Support for `char` is deprecated, use `int8_t` or `uint8_t` instead" was added to allow a smooth transition.
+>
+> #### `as<T>()` always returns `T`
+>
+> Previously, `JsonVariant::as<T>()` could return a type different from `T`.
+> The most common example is `as<char*>()` that returned a `const char*`.
+> While this feature simplified a few use cases, it was confusing and complicated the
+> implementation of custom converters.
+>
+> Starting from this version, `as<T>` doesn't try to auto-correct the return type and always return `T`,
+> which means that you cannot write this anymore:
+>
+> ```c++
+> Serial.println(doc["sensor"].as<char*>());  // error: invalid conversion from 'const char*' to 'char*' [-fpermissive]
+> ```
+> 
+> Instead, you must write:
+>
+> ```c++
+> Serial.println(doc["sensor"].as<const char*>());  // OK
+> ```
+>
+> A deprecation warning with the message "Replace `as<char*>()` with `as<const char*>()`" was added to allow a smooth transition.
+>
+> #### `DeserializationError::NotSupported` removed
+>
+> On a different topic, `DeserializationError::NotSupported` has been removed.
+> Instead of returning this error:
+>
+> * `deserializeJson()` leaves `\uXXXX` unchanged (only when `ARDUINOJSON_DECODE_UNICODE` is `0`)
+> * `deserializeMsgPack()` replaces unsupported values with `null`s
+>
+> #### Const-aware `is<T>()`
+>
+> Lastly, a very minor change concerns `JsonVariantConst::is<T>()`.
+> It used to return `true` for `JsonArray` and `JsonOject`, but now it returns `false`.
+> Instead, you must use `JsonArrayConst` and `JsonObjectConst`.
+
+v6.17.3 (2021-02-15)
+-------
+
+* Made `JsonDocument`'s destructor protected (issue #1480)
+* Added missing calls to `client.stop()` in `JsonHttpClient.ino` (issue #1485)
+* Fixed error `expected ')' before 'char'` when `isdigit()` is a macro (issue #1487)

+* PlatformIO: set framework compatibility to `*` (PR #1490 by @maxgerhardt)
+
+v6.17.2 (2020-11-14)
+-------
+
+* Fixed invalid conversion error in `operator|(JsonVariant, char*)` (issue #1432)
+* Changed the default value of `ARDUINOJSON_ENABLE_PROGMEM` (issue #1433).

+-------
+
+* Fixed error `ambiguous overload for 'operator|'` (issue #1411)

+* Added `JsonDocument::overflowed()` which tells if the memory pool was too small (issue #1358)
+* Added `DeserializationError::EmptyInput` which tells if the input was empty
+* Added `DeserializationError::f_str()` which returns a `const __FlashStringHelper*` (issue #846)
+* Added `operator|(JsonVariantConst, JsonVariantConst)`
+* Added filtering for MessagePack (issue #1298, PR #1394 by Luca Passarella)
+* Moved float convertion tables to PROGMEM
+* Fixed `JsonVariant::set((char*)0)` which returned false instead of true (issue #1368)

+
+v6.16.1 (2020-08-04)
+-------
+
+* Fixed `deserializeJson()` that stopped reading after `{}` (issue #1335)

+* Added string deduplication (issue #1303)
+* Added `JsonString::operator!=`
+* Added wildcard key (`*`) for filters (issue #1309)
+* Set `ARDUINOJSON_DECODE_UNICODE` to `1` by default
+* Fixed `copyArray()` not working with `String`, `ElementProxy`, and `MemberProxy`

+* Fixed excessive stack usage when compiled with `-Og` (issues #1210 and #1314)
+* Fixed `Warning[Pa093]: implicit conversion from floating point to integer` on IAR compiler (PR #1328 by @stawiski)
+
+v6.15.2 (2020-05-15)
+-------
+
+* CMake: don't build tests when imported in another project
+* CMake: made project arch-independent
+* Visual Studio: fixed error C2766 with flag `/Zc:__cplusplus` (issue #1250)
+* Added support for `JsonDocument` to `copyArray()` (issue #1255)
+* Added support for `enum`s in `as<T>()` and `is<T>()`  (issue #1256)
+* Added `JsonVariant` as an input type for `deserializeXxx()`  
+  For example, you can do: `deserializeJson(doc2, doc1["payload"])`
+* Break the build if using 64-bit integers with ARDUINOJSON_USE_LONG_LONG==0
+
+v6.15.1 (2020-04-08)

+* Fixed incorrect string comparison on some platforms (issue #1198)
+* Added move-constructor and move-assignment to `BasicJsonDocument`
+* Added `BasicJsonDocument::garbageCollect()` (issue #1195)
+* Added `StaticJsonDocument::garbageCollect()`
+* Changed copy-constructor of `BasicJsonDocument` to preserve the capacity of the source.
+* Removed copy-constructor of `JsonDocument` (issue #1189)
+
+> ### BREAKING CHANGES
+> 
+> #### Copy-constructor of `BasicJsonDocument`
+>
+> In previous versions, the copy constructor of `BasicJsonDocument` looked at the source's `memoryUsage()` to choose its capacity.
+> Now, the copy constructor of `BasicJsonDocument` uses the same capacity as the source.
+>
+> Example:
+>
+> ```c++
+> DynamicJsonDocument doc1(64);
+> doc1.set(String("example"));
+>
+> DynamicJsonDocument doc2 = doc1;
+> Serial.print(doc2.capacity());  // 8 with ArduinoJson 6.14
+>                                 // 64 with ArduinoJson 6.15
+> ```
+>
+> I made this change to get consistent results between copy-constructor and move-constructor, and whether RVO applies or not.
+>
+> If you use the copy-constructor to optimize your documents, you can use `garbageCollect()` or `shrinkToFit()` instead.
+>
+> #### Copy-constructor of `JsonDocument`
+>
+> In previous versions, it was possible to create a function that take a `JsonDocument` by value.
+>
+> ```c++
+> void myFunction(JsonDocument doc) {}
+> ```
+>
+> This function gives the wrong clues because it doesn't receive a copy of the `JsonDocument`, only a sliced version.
+> It worked because the copy constructor copied the internal pointers, but it was an accident.
+>
+> From now, if you need to pass a `JsonDocument` to a function, you must use a reference:
+>
+> ```c++
+> void myFunction(JsonDocument& doc) {}
+> ```
+
+v6.14.1 (2020-01-27)
+-------
+
+* Fixed regression in UTF16 decoding (issue #1173)
+* Fixed `containsKey()` on `JsonVariantConst`
+* Added `getElement()` and `getMember()` to `JsonVariantConst`
+
+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)

+* Fixed dangling reference in copies of `MemberProxy` and `ElementProxy` (issue #1120)
+
+v6.12.0 (2019-09-05)
+-------

+
+> ### 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>())`.
+
+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<T>()` and `JsonVariant::is<T>()`.
+   - `as<T>()` returns `0` if the integer `T` overflows

+
+> ### BREAKING CHANGES
+> 
+> #### `DynamicJsonDocument`'s constructor
+> 
+> The parameter to the constructor of `DynamicJsonDocument` is now mandatory
+>
+> Old code:
+>
+> ```c++

+> New code:
+>
+> ```c++
+> DynamicJsonDocument doc(1024);
+> ```
+> 
+> #### Nesting limit
+> 
+> `JsonDocument::nestingLimit` was replaced with a new parameter to `deserializeJson()` and `deserializeMsgPack()`.
+> 
+> Old code:
+> 
+> ```c++
+> doc.nestingLimit = 15;
+> deserializeJson(doc, input);
+> ```
+> 
+> New code: 
+> 
+> ```c++

+> ```
+
+v6.7.0-beta (2018-12-07)

+> It's a reference to a value stored in the `JsonDocument`.
+> As a consequence, a `JsonVariant` cannot be used as a standalone variable anymore.
+>
+> Old code:
+>
+> ```c++
+> JsonVariant myValue = 42;
+> ```
+>
+> New code:

+> #### Preformatted values
+>
+> Old code:
+>
+> ```c++
+> object["values"] = RawJson("[1,2,3,4]");

+-----------
+
+* Return `JsonArray` and `JsonObject` by value instead of reference (issue #309)

+
+> ### BREAKING CHANGES
+> 
+> Old code:
+>
+> ```c++
+> JsonObject& obj = doc.to<JsonObject>();
+> JsonArray& arr = obj.createNestedArray("key");
+> if (!arr.success()) {
+>   Serial.println("Not enough memory");
+>   return;
+> }
+> ```

+## Quickstart
+
+### Deserialization
+
+Here is a program that parses a JSON document with ArduinoJson.
+
+```c++
+char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
+
+DynamicJsonDocument doc(1024);
+deserializeJson(doc, json);
+
+const char* sensor = doc["sensor"];
+long time          = doc["time"];
+double latitude    = doc["data"][0];
+double longitude   = doc["data"][1];
+```
+
+See the [tutorial on arduinojson.org](https://arduinojson.org/v6/doc/deserialization/)
+
+### Serialization
+
+Here is a program that generates a JSON document with ArduinoJson:
+
+```c++
+DynamicJsonDocument doc(1024);
+
+doc["sensor"] = "gps";
+doc["time"]   = 1351824120;
+doc["data"][0] = 48.756080;
+doc["data"][1] = 2.302038;
+
+serializeJson(doc, Serial);
+// This prints:
+// {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}
+```
+
+See the [tutorial on arduinojson.org](https://arduinojson.org/v6/doc/serialization/)
