 ## v1.1.0 (2017-06-28) ##
 
- * Empty objects and objects that don't implement `Traversable` are now always
-   encoded as JSON objects (for `json_encode()` compatibility).
- * Associative array testing now returns faster and more memory efficiently
- * JSON encoding errors now contain the error constant
- * The visibility for `write()` method in `StreamJsonEncoder` and
-   `BufferJsonEncoder` has been changed to protected (as originally intended)
- * A protected method `getValueStack()` has been added to `AbstractJsonEncoder`
-   that returns current unresolved value stack (for special write method
+ * For `json_encode()` compatibility, all objects are encoded as JSON objects
+   unless they implement `Traversable` and either return `0` as the first key or
+   return no values at all.
+ * Testing for associative arrays is now more memory efficient and fails faster.
+ * JSON encoding errors now contain the error constant.
+ * The visibility for `StreamJsonEncoder::write()` and `BufferJsonEncoder::write()`
+   has been changed to protected (as was originally intended).
+ * A new protected method `AbstractJsonEncoder::getValueStack()` has been added
+   that returns the current unresolved value stack (for special write method
    implementations). 
- * An overridable protected method `resolveValue()` has been added to
-   `AbstractJsonEncoder` which is used to resolve closures and objects
-   implementing `JsonSerializable`.
+ * An overridable protected method `AbstractJsonEncoder::resolveValue()` has
+   been added which is used to resolve objects (i.e. resolving the value of
+   closures and objects implementing `JsonSerializable`).
