Gnatsweb 2.x is in maintenance-only mode. However, it appeared worthwhile to backport a few features from the imminent 4.0 version (which will only work with GNATS 4). The single major new feature is a navigation bar on top of all pages with links to all major Gnatsweb functions. Minor fixes and enhancements include proper handling of a locked GNATS database, fixes related to attachment handling, and inclusion of an X-Mailer header in outgoing mail. 2.x versions of Gnatsweb only support GNATS 3.x.
