 # Changelog #
 
+## v2.4.0 (2018-07-03) ##
+
+  * Added `string.classes` option, which allows to define an array of classes or
+    namespaces to encode using the `::class` format, when encountered as strings
+  * Added `string.imports` options, which allows to define the used imports to write
+    the `::class` format strings using shorter imported notation
+  * Support for HHVM has been dropped, as HHVM no longer aims for PHP compatibility
+  * Added travis builds for PHP 7.2
+  * Change some rules in the used coding standard 
+
 ## v2.3.0 (2017-07-15) ##
 
   * Added `string.utf8` option which causes the string encoder to escape all

     multibyte UTF-8 characters in strings are encoded using the PHP7 unicode

     earlier than 7.0.

+  * **string.classes** : &lt;string[]&gt; ([])<br>
+    Defines a list of classes or class namespace prefixes for classes that
+    can be encoded using the class resolution operator `::class` when 
+    encountered in strings. e.g. providing the value `['Riimu\\']` would encode

+    
+  * **string.imports** : &lt;string[]&gt; ([])<br>
+    List of imports used in the resulting code file, which allows class names
+    to be written using shorter format. The list should be an associative array
+    with the namespace or class as the key and the used name as the value. Use
+    empty string to indicate the current namespace.
+    
+    For example, if the resulting file would have `namespace Riimu\Kit\PHPEncoder;`
+    and `use PHPUnit\Framework\TestCase;`, you could set up the array as
+    `['Riimu\\Kit\\PHPEncoder\\' => '', 'PHPUnit\\Framework\\TestCase' => 'TestCase']`

     When set to `true`, arrays are enclosed using square brackets `[]` instead
