| Commons Lang Package |
| Version 3.0-beta |
| 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. |
| |
| Note that this is a Beta release. The API is largely stable, and we're eager for feedback on |
| the mailing list or issue tracker. |
| |
