Support

Support for GT4 development releases is available through the gt4-friends mailing list. For more information, see http://www-unix.globus.org/toolkit/docs/4.0/GT4Facts/friends.html.

Testing

The following components have a "Call for Community Testing" associated with them. A "Call for Community Testing" is a mechanism to notify our users that new Globus code is available for testing in the field. Through these calls, the Globus Alliance hopes to expose its code to a wide variety of usage scenarios early in its development process. The ultimate goals are to catch bugs that have historically been found only after final releases, and to elicit feedback from the community on ways our software can be improved.
