GradeL 0.11.2 has been released. You can grab the source package or the Ubuntu Karmic .deb package from the download page (the .deb file should work on any Debian based distro also). This release includes several bug fixes and a few small feature enhancements and additions, including the new report that displays category averages for each student. For details on these updates and changes please review the ChangeLog.
As you already know, GradeL is a small, open-source project. Please continue to provide feedback and report bugs that you may encounter. While GradeL development is slow, it is still moving forward with your help.
