3.8.2 is mainly a bug-fix only release. All major new enhancements are being scheduled for 3.9. We are planning on many xdoclet enhancements in that release. For now, you can update xdoclet module jar files by dropping in new modules files in the xdoclet core plugin and hitting “refresh” in the both xdoclet preference pages.
Just out of curiousity, what specific feature/version in xdoclet were you wanting?
