 Arduino JSON: change log
 ========================
 
+v4.6
+----
+
+* Fixed segmentation fault in `DynamicJsonBuffer` when memory allocation fails (issue #92)
+
+v4.5
+----
+
+* Fixed buffer overflow when input contains a backslash followed by a terminator (issue #81)
+
+**Upgrading is recommended** since previous versions contain a potential security risk.
+
+Special thanks to [Giancarlo Canales Barreto](https://github.com/gcanalesb) for finding this nasty bug.
+
+v4.4
+----
+
+* Added `JsonArray::measureLength()` and `JsonObject::measureLength()` (issue #75)
+
+v4.3
+----
+
+* Added `JsonArray::removeAt()` to remove an element of an array (issue #58)
+* Fixed stack-overflow in `DynamicJsonBuffer` when parsing huge JSON files (issue #65)
+* Fixed wrong return value of `parseArray()` and `parseObject()` when allocation fails (issue #68)
+
+v4.2
+----
+
+* Switched back to old library layout (issues #39, #43 and #45)
+* Removed global new operator overload (issue #40, #45 and #46)
+* Added an example with EthernetServer
+
 v4.1
