The Apache Commons Team is pleased to announce the availability of Apache Commons Configuration 2.0. The Commons Configuration software library provides a generic configuration interface which enables an application to read configuration data from a variety of sources. After a series of alpha and beta releases, this is the first final release for Apache Commons Configuration 2.0. Version 2 is a major redesign of the Configuration API. It breaks compatibility in many areas and, therefore, is not a drop-in replacement for Commons Configuration 1.x. Changes on client code are required. If you want to upgrade from Commons Configuration 1.x to the new version, make sure to consult the upgrade guide at http://commons.apache.org/configuration/userguide/upgradeto2_0.html which describes the breaking changes. A full list of all changes can be found in the release notes at http://www.apache.org/dist/commons/configuration/RELEASE-NOTES.txt The user's guide has been updated to describe all the new features of Configuration 2.0. It can be found at http://commons.apache.org/configuration/userguide/user_guide.html Source and binary distributions are available for download from the Apache Commons download site: http://commons.apache.org/proper/commons-configuration/download_configuration.cgi Please verify signatures using the KEYS file available at the above location when downloading the release.
