==============================================================================
Apache Commons IO Version 2.6
==============================================================================

INTRODUCTION:

Apache 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.

Apache Commons IO 2.6 requires at least Java 7 to build and run.


DEPRECATIONS
============

All closeQuietly overloads in org.apache.commons.io.IOUtils have been
deprecated. Use the try-with-resources statement or handle suppressed
exceptions manually.

The class org.apache.commons.io.FileSystemUtils has been deprecated.
Use equivalent methods in java.nio.file.FileStore instead, e.g.
Files.getFileStore(Paths.get("/home")).getUsableSpace() or iterate over
FileSystems.getDefault().getFileStores().


COMPATIBILITY WITH JAVA 9
==================

The MANIFEST.MF now contains an additional entry:

  Automatic-Module-Name: org.apache.commons.io

This should make it possible to use Commons IO 2.6 as a module in the Java 9
module system. For more information see the corresponding issue:

    https://issues.apache.org/jira/browse/IO-551

Building Commons IO 2.6 should work out of the box with the latest Java 9
release. Please report any Java 9 related issues at:

    https://issues.apache.org/jira/browse/IO


NEW FEATURES
============

o IO-551: Add Automatic-Module-Name MANIFEST entry for Java 9 compatibility.
o IO-367: Add convenience methods for copyToDirectory. Thanks to James Sawle.
o IO-493: Add infinite circular input stream. Thanks to Piotr Turski.

o IO-518: Add ObservableInputStream.
o IO-519: Add MessageDigestCalculatingInputStream.
o IO-513: Add convenience methods for reading class path resources.
          Thanks to Behrang Saeedzadeh.

o IO-550: Documentation issue, fix 404 Javadoc issues in the description page.
          Thanks to Jimi Adrian.

          parent.
