| 25 | + <section name="Upgrade"> |
| 26 | + <p> |
| 27 | + These are the release notes and advice for upgrading Apache Commons IO from |
| 28 | + version 2.5 to version 2.6 |
| 29 | + <source> |
| 30 | + Apache Commons IO is a package of Java utility classes like java.io. |
| 31 | + Classes in this package are considered to be so standard and of such high |
| 32 | + reuse as to justify existence in java.io. |
| 33 | + |
| 34 | + The Apache Commons IO library contains utility classes, stream implementations, |
| 35 | + file filters, file comparators, endian transformation classes, and much more. |
| 36 | + |
| 37 | + Apache Commons IO 2.6 requires at least Java 7 to build and run. |
| 38 | + |
| 39 | + |
| 40 | + DEPRECATIONS |
| 41 | + ============ |
| 42 | + |
| 43 | + All closeQuietly overloads in org.apache.commons.io.IOUtils have been |
| 44 | + deprecated. Use the try-with-resources statement or handle suppressed |
| 45 | + exceptions manually. |
| 46 | + |
| 47 | + The class org.apache.commons.io.FileSystemUtils has been deprecated. |
| 48 | + Use equivalent methods in java.nio.file.FileStore instead, e.g. |
| 49 | + Files.getFileStore(Paths.get("/home")).getUsableSpace() or iterate over |
| 50 | + FileSystems.getDefault().getFileStores(). |
| 51 | + |
| 52 | + |
| 53 | + COMPATIBILITY WITH JAVA 9 |
| 54 | + ================== |
| 55 | + |
| 56 | + The MANIFEST.MF now contains an additional entry: |
| 57 | + |
| 58 | + Automatic-Module-Name: org.apache.commons.io |
| 59 | + |
| 60 | + This should make it possible to use Commons IO 2.6 as a module in the Java 9 |
| 61 | + module system. For more information see the corresponding issue: |
| 62 | + |
| 63 | + https://issues.apache.org/jira/browse/IO-551 |
| 64 | + |
| 65 | + Building Commons IO 2.6 should work out of the box with the latest Java 9 |
| 66 | + release. Please report any Java 9 related issues at: |
| 67 | + |
| 68 | + https://issues.apache.org/jira/browse/IO |
