On Thursday 1 April 2010, FET-5.13.1 was released. There are some bug fixes and improvements and you are advised to get the new version.
From ChangeLog:
- Corrected a generation bug (probably very rare, it gave impossible timetable). Bug may have appeared if using constraints students (set) early with max beginnings at second hour >= 1 and generating on a locked file.
- Increased maximum number of teachers, subjects, rooms and buildings to 6000 (they were 3000 previously).
- Corrected some HTML minor problems, by Volker Dirr.
- Added a new sample file, by alfaromeo (from Morocco). This user also describes tricks to use official FET for Moroccan schools.
