ArduinoJson: change log
=======================
HEAD
----
v6.18.0 (2021-05-05)
-------
* Added support for custom converters (issue #687)
* Added support for `Printable` (issue #1444)
* Removed support for `char` values, see below (issue #1498)
* `deserializeJson()` leaves `\uXXXX` unchanged instead of returning `NotSupported`
* `deserializeMsgPack()` inserts `null` instead of returning `NotSupported`

* Added `JsonVariant::is<JsonArrayConst/JsonObjectConst>()` (issue #1412)
* Added `JsonVariant::is<JsonVariant/JsonVariantConst>()` (issue #1412)
* Changed `JsonVariantConst::is<JsonArray/JsonObject>()` to return `false` (issue #1412)
* Simplified `JsonVariant::as<T>()` to always return `T` (see below)
* Updated folders list in `.mbedignore` (PR #1515 by @AGlass0fMilk)
* Fixed member-call-on-null-pointer in `getMember()` when array is empty
* `serializeMsgPack(doc, buffer, size)` doesn't add null-terminator anymore (issue #1545)
* `serializeJson(doc, buffer, size)` adds null-terminator only if there is enough room
* PlatformIO: set `build.libArchive` to `false` (PR #1550 by @askreet)

> #### Support for `char` removed

> We cannot cast a `JsonVariant` to a `char` anymore, so the following will break:

> 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`,
