Lang is now Java 5 based. We've generified the API, moved certain APIs to support varargs
and thrown out any features
that are now supported by Java itself. We've removed the deprecated parts of the API and have also removed some features that
were deemed weak or unnecessary. All of this means that Lang 3.0 is not backwards compatible.
To that end we have changed the package name, allowing Lang 3.0 to sit side-by-side with your previous version of Lang without any bad side effects. The new package name is the exciting and original org.apache.commons.lang3
.

As you'd expect, there are also new features, enhancements and bugs fixed.
+Despite the label of backwards incompatibility, in the vast majority of cases the simple addition of a '3'
to an import statement will suffice for your migration.

Two new packages have shown up. org.apache.commons.lang3.concurrent, which unsurprisingly provides support classes for multi-threaded programming, and org.apache.commons.lang3.text.translate, which provides a pluggable API for text transformation.
