+### 1.5.1 (2014-04-19)
+
+  * Fixed toAscii() failing to remove remaining non-ascii characters
+  * Updated slugify() to treat dash and underscore as delimiters by default
+  * Updated slugify() to remove leading and trailing delimiter, if present
+
+### 1.5.0 (2014-03-19)
+
+  * Made both str and encoding protected, giving property access to subclasses
+  * Added getEncoding()
+  * Fixed isJSON() giving false negatives
+  * Cleaned up and simplified: replace(), collapseWhitespace(), underscored(),
+    dasherize(), pad(), padLeft(), padRight() and padBoth()
+  * Fixed handling consecutive invalid chars in slugify()
+  * Removed conflicting hard sign transliteration in toAscii()
+
+### 1.4.0 (2014-02-12)
+
+  * Implemented the IteratorAggregate interface, added chars()
+  * Renamed count() to countSubstr()
+  * Updated count() to implement Countable interface
+  * Implemented the ArrayAccess interface with positive and negative indices
+  * Switched from PSR-0 to PSR-4 autoloading
+
+### 1.3.0 (2013-12-16)
+
+  * Additional Bulgarian support for toAscii
+  * str property made private
+  * Constructor casts first argument to string
+  * Constructor throws an InvalidArgumentException when given an array
+  * Constructor throws an InvalidArgumentException when given an object without
+    a __toString method
+
 ### 1.2.2 (2013-12-04)

  * Updated create function to use late static binding

+## Implemented Interfaces
+
+`Stringy\Stringy` implements the `IteratorAggregate` interface, meaning that
+`foreach` can be used with an instance of the class:
+
+``` php
+$stringy = S::create('Fòô Bàř', 'UTF-8');
+foreach ($stringy as $char) {
+    echo $char;
+}
+// 'Fòô Bàř'
+```
+
+It implements the `Countable` interface, enabling the use of `count()` to
+retrieve the number of characters in the string:
+
+``` php
+$stringy = S::create('Fòô', 'UTF-8');
+count($stringy);  // 3
+```
+
+Furthermore, the `ArrayAccess` interface has been implemented. As a result,
+`isset()` can be used to check if a character at a specific index exists. And
+since `Stringy\Stringy` is immutable, any call to `offsetSet` or `offsetUnset`
+will throw an exception. `offsetGet` has been implemented, however, and accepts
+both positive and negative indexes. Invalid indexes result in an
+`OutOfBoundsException`.
+
+``` php
+$stringy = S::create('Bàř', 'UTF-8');
+echo $stringy[2];     // 'ř'
+echo $stringy[-2];    // 'à'
+isset($stringy[-4]);  // false
+
+$stringy[3];          // OutOfBoundsException
+$stringy[2] = 'a';    // Exception
+```
