Release notes

These are the release notes for Commons CLI 1.3.


This document contains the release notes for this version of the Commons CLI
package. Commons CLI provides a simple API for working with the command line
arguments and options.

Commons CLI 1.3 is a bugfix and feature release and binary compatible with the
previous versions, except for the OptionValidator class that is no longer public
(change introduced in v1.2). Commons CLI 1.3 at least requires Java 5.0.

A new parser is available: DefaultParser. It combines the features of the
GnuParser and the PosixParser. It also provides additional features like
partial matching for the long options, and long options without
separator (i.e like the JVM memory settings: -Xmx512m). This new parser
deprecates the previous ones.
