PRISM is under constant development. This means that some of the most recent improvements, extensions and bug fixes may not yet be available in the version available for general download.
Here, you can get access to development versions of PRISM. These are basically recent snapshots from the Subversion repository used by the PRISM developers. They should therefore be considered less stable than public releases. New features may not yet be documented and may change and/or disappear at the whim of the PRISM developers. These releases are distributed only as source code and as a Windows installer and, like the main PRISM releases, are distributed under the GPL. Please feel free to ask questions in the discussion group. As usual, your feedback, good or bad, is very much appreciated.
Currently, the main public release of PRISM (version 3.3) is the most up-to-date available. Check back here soon for updates.
