Commons Lang Package

|
Version 3.0
|
|
Release Notes
|
|
|
|
|
|
INTRODUCTION:
|
|
|
|
This document contains the release notes for the 3.0 version of Apache Commons Lang.
|
|
Commons Lang is a set of utility functions and reusable components that should be of use in any
|
|
Java environment.
|
|
|
|
Lang 3.0 now targets Java 5.0, making use of features that arrived with Java 5.0 such as generics,
|
|
variable arguments, autoboxing, concurrency and formatted output.
|
|
|
|
For the latest advice on upgrading, see the following page:
