You can download the archived v0.9.11 distribution of Project Darkstar technology here.  Archives of all distributions are also available. 

Project Darkstar distributions are published periodically as stable, documented releases of the technology, and are recommended for use by most developers.  If you are interested in the leading edge of Project Darkstar development, you may prefer to download the less well tested weekly builds or to work directly from the source code repository.

This Project Darkstar distribution includes the Project Darkstar Server core technology component and two Project Darkstar Client SDK components, giving you everything you need to build online game servers and connect them to your clients.

Most of the Project Darkstar Server is released under the Gnu Public License, v2 (GPLv2), although server-side programming APIs are licensed under the Gnu Public License, v2 with classpath exception.  The Project Darkstar Client SDKs included in this distribution are released under a Berkeley Software Distribution (BSD) license. This licensing structure supports Sun's intent that developers who use Project Darsktar be free to redistribute the online game code they independently develop (e.g., code that is not a modification or other derivative of Project Darkstar code), on both the client and server side, under a license of their own choosing.

Current Release: 0.9.11
Release Date: October 29, 2009
The 0.9.11 distribution release introduces a new extension system that eases building, distributing, and using custom components designed to extend the core functionality of the Project Darkstar Server.  The new system establishes a standardized extension format that supports automatically deploying and enabling custom services, authenticators, and other pluggable components in the core.  Other highlights of the release include the new shouldContinue() method on the TaskManager API to assist in breaking down work into smaller task units.  Information about all of the enhancements and bug fixes introduced in this release can be found in the changelog files for each download.
