 ArduinoJson: change log
 =======================
 
+v5.6.3
+------
+
+* Improved speed of float serialization (about twice faster)
+* Added `as<JsonArray>()` as a synonym for `as<JsonArray&>()`... (issue #291)
+* Fixed `call of overloaded isinf(double&) is ambiguous` (issue #284)
+
+v5.6.2
+------
+
+* Fixed build when another lib does `#undef isnan` (issue #284)
+
 v5.6.1
