+Apache Commons IO 2.16.0 Release Notes
+
+Introduction
+------------
+
+Commons IO is a package of Java utility classes like java.io.  
+Classes in this package are considered to be so standard and of such high 
+reuse as to justify existence in java.io.
+
+The Apache Commons IO library contains utility classes, stream implementations, file filters,
+file comparators, endian transformation classes, and much more.
+
+Java 8 is required.
