Features:

• FET is free software (open source). You can freely use, copy, modify and re-distribute it, as GNU/GPL permits (but please consider a donation)
• Localized to English, French, Catalan, Romanian, Malay, Polish, Turkish, Dutch, German, Hungarian and Macedonian (maybe incompletely)
• Fully automatic generation algorithm, allowing also semi-automatic or manual allocation
• Platform independent implementation, allowing running on GNU/Linux, Windows, Mac and any system that Qt supports
• Powerful flexible modular xml format for the input file, allowing editing with an xml editor or by hand (besides FET)
• Possibility to view the currently generated timetable without stopping the ongoing simulation
• The resulted timetables are exported into xml and html formats
• Very flexible students (pupils) structure, in years, groups and subgroups. FET allows overlapping years and groups and non-overlapping subgroups
• Possibility to consider a weight (percentage) for each constraint
• Maximum total number of hours (periods) per day: 30
• Maximum number of working days per week: 14
• Maximum total number of teachers: 700
• Maximum total number of subgroups (sets) of students: 5000
• Maximum total number of subjects: 1000
• Virtually unlimited number of subject tags
• Maximum number of activities: 2000 (you can compile or ask the author a version with more activities allowed)
• Maximum number of rooms: 300
• Maximum number of buildings: 100
• Maximum number of equipments: 300
• Adjustable duration for each activity (each activity can have duration of 1 hour, 2 hours, 3 hours or more)
• Possibility of adding multiple teachers and students sets for each activity. That is, each activity can have specified at most 400 students subgroups (sets) and 100 teachers
• Maximum number of time constraints: 3000
• Maximum number of space constraints: 3000
• A large and flexible palette of time constraints
• A large and flexible palette of space constraints

What's New in version 5.11.0:

• Updated to Qt 4.5.2
• Converted all dialogs to Qt 4 Designer files - suggested by George Miliotis. Compilation time is now shorter and intermediary and executable files are smaller.
• Added constraint teacher(s) min days per week (suggested by several users).
• Added constraint teacher(s) or students (set) for an activity tag maximum hours daily (suggested by several users). It is not perfect and must be enabled from settings menu.
• Added constraint students (set) max gaps per day. It is not perfect and must be enabled from settings menu.
• Very rare crash bug fix (reported by Marco Barsotti).
• Constraint room not available times permits now multiple constraints for the same room (so, you can use multiple constraints with different weights and preferences for the same room).
• In add/modify activity and modify subactivity dialogs, the students are displayed in a tree-like structure (suggested by George Miliotis).
• In all constraints dialogs, added a nice filter (suggested by daviodan).
• Changed name of constraint: MinNDaysBetweenActivities becomes MinDaysBetweenActivities.
• Added a count for activities list and constraints list.
• The constraints with tables now contain an X (nicer look), also centered nicely, and they have colors (which can be enabled in settings)
• The timetables view forms now center text in cells.
• Many other minor interface improvements.
• Rewritten the Catalan translation by Silvia. It is very complete, check it out.
• Added a new Greek sample file, by George Miliotis.
• Updated and improved Persian translation by sally sat.
• Dropped !DOCTYPE FET tag in the .fet files - following general recommendations, and changed FET tag to fet tag. Of course you can open older files.
• Improved activities simple description (suggested by Massimo Mancini and alfaromeo).
• Added possibility to save the highest stage timetable (suggested by alfaromeo, pinco and Massimo Mancini).
• Added a new Romanian sample file, by Horatiu Halmajan.
• Updated translations: Russian, German, Romanian, Italian, Spanish.
• The timetable view dialogs now have resizeable widgets (you can drag the sections with the mouse) - suggested by Ben Bauer.
