----
* Fixed IntelliSense errors in Visual Micro (issue #483)
* Fixed compilation in IAR Embedded Workbench (issue #515)
* Added `ARDUINOJSON_DOUBLE_IS_64BITS`
* Added `ARDUINOJSON_EMBEDDED_MODE`
v5.10.0
-------
* Removed configurable number of decimal places (issues #288, #427 and #506)
* Changed exponentation thresholds to `1e7` and `1e-5` (issues #288, #427 and #506)
* Changed exponentiation thresholds to `1e7` and `1e-5` (issues #288, #427 and #506)
* `JsonVariant::is<double>()` now returns `true` for integers
* Fixed error `IsBaseOf is not a member of ArduinoJson::TypeTraits` (issue #495)
* Fixed error `forming reference to reference` (issue #495)
