-Arduino JSON: change log
-========================
+ArduinoJson: change log
+=======================
+
+v5.0 (currently in beta)
+----
+
+* Added support of `String` class (issues #55, #56, #70, #77)
+* Added `JsonBuffer::strdup()` to make a copy of a string (issues #10, #57)
+* Implicitly call `strdup()` for `String` but not for `char*` (issues #84, #87)
+* Added support of non standard JSON input (issue #44)
+* Added support of comments in JSON input (issue #88)
+* Redesigned `JsonVariant` to leverage converting constructors instead of assignment operators (issue #66)
+* Switched to new the library layout (requires Arduino 1.0.6 or above)
+
+**BREAKING CHANGES**:
+- `JsonObject::add()` was renamed to `set()`
+- `JsonArray::at()` and `JsonObject::at()` were renamed to `get()`
+- Number of digits of floating point value are now set with `double_with_n_digits()`
+
+**Personal note about the `String` class**:
+Support of the `String` class has been added to the library because many people use it in their programs.
+However, you should not see this as an invitation to use the `String` class.
+The `String` class is **bad** because it uses dynamic memory allocation.
+Compared to static allocation, it compiles to a bigger, slower program, and is less predictable.
+You certainly don't want that in an embedded environment!
+
+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
