+ * 1.4
+ * - Some comments improved, other minor improvements
* 1.3
* - Constructor is now empty and factory method 'createClassLoader' is created
* - renamed loadClasses to scanClassPath
- * - Added initLoader(), $configInstance renamed to $configInstance
+ * - Added initLoader()
* 1.2
* - ClassLoader rewritten to PHP SPL's own RecursiveIteratorIterator class
* 1.1
