May 14th, 2012· Very serious old bug fix. This was found trying to implement the new constraint (see below) in such a way to solve a more complicated file by Yush Yuen. Since nobody complained, it seems that until now the bug was not critical (but might have slowed down some timetables which have rooms and preferred/home rooms constraints). Bug exists from the start of the implementation of the space allocation in FET, probably. A big 'Thank you!' to Yush Yuen, who was very helpful in finding the problem.
· Added a new constraint, activities occupy max different rooms (which can, for example, constrain some activities to be in the same room (in different time slots, of course) if max different rooms = 1). Suggested by Yush Yuen, nomad, Volker Dirr and maybe others.
· Safe saving of .fet files (save with .fet.tmp name, then remove old .fet file, then rename .fet.tmp to .fet).
· Saving of the random seed after the end of the generation (in addition to saving it at the beginning).
· Added an Uzbek translation, by Orzubek Eraliyev.
April 18th, 2012· Printing of the timetables (directly from the interface), by Volker Dirr (suggested by Bobby Wise, Anwarul Alam, daviodan and maybe other users).
· Updated to Qt 4.8.1.
· Minor interface improvements and bug fixes.
· Added a new Greek sample file, by Petros Nouvakis.
March 6th, 2012· Updated to Qt 4.8.0.
· Bug fix: command line interface now accepts backslash native characters under Windows (reported by Sarwan Bangar).
· When using command line with a time limit, and the time limit is exceeded, FET will save the highest stage and the current timetable. Suggestion and code by Ian Holden.
· Exporting of the timetable as a CSV file now saves also the activities comments (suggested by m, implemented by Volker Dirr).
· Minor bug fix in HTML timetables, by Volker Dirr.
· Minor interface bug fixes.
December 12th, 2011· Each constraint can be activated/deactivated and also each constraint may have an optional comment. The user can sort the constraints based on their comment. These special functions can only be accessed from all time/space constraints dialogs (suggested by George Miliotis, Davide G. M. Salvetti and maybe other users).
· Each activity may have an optional comment (suggested by K, m and maybe other users).
· The command line version now saves the current timetable and the highest stage timetable if it receives SIGTERM from the user, then exits (suggested by Davide G. M. Salvetti and maybe other users).
· Added a Vietnamese translation, by Nguyen Truong Thang.
· Minor interface bug fixes.
· Updated the Saudi Arabia examination timetable file, by Silver.
October 28th, 2011Added two new constraints:
· 1) Activities occupy max time slots from selection. This is useful in more cases, for instance to force some teachers to have activities in certain time slots. (For example, if in a 5 days week with 6 hours per day, teacher T has 20 hours of activities and needs to have activities in the first 3 hours of Monday: add a constraint with all the teacher's activities, all time slots minus these 3 (so 5*6-3=27 slots selected in the constraint), and specify the maximum number of selected time slots occupied by the selected activities to be 17.) Suggested by Zsolt Udvari, Christian Kemmer, Davide G. M. Salvetti, lalloso, Silver, and maybe other users.
· 2) Activities max simultaneous in selected time slots. User chooses a set of activities, a set of time slots, and specifies that in each time slot there should be an upper limit on the activities from the chosen set. Useful for example if you want each slot to have say at least 3 free teachers, for substitution or supervision.
· Updated to Qt 4.7.4.
· Removed dependence of Qt3Support classes. Many dialogs were changed. This is to improve FET and to prepare it for the future Qt 5.
· The program is now storing the geometry of most dialogs (suggested by more users. Zsolt Udvari suggested to store also the Activity planning dialog settings).
· The activity tags, students, teachers, subjects, rooms, buildings, activities, subactivities, all time constraints and all space constraints dialogs contain a draggable splitter, for better viewing (suggested by daviodan).
· Taking care of when a file was modified. When it was not modified, the user can quit FET directly (suggested by Horatiu Halmajan and maybe other users).
· Recently used files list (suggested by daviodan, Silver and maybe other users).
· Activities rooms statistics it shows the list of activities which will certainly or possibly be scheduled in an unspecified room (suggested by Volker Dirr, who also did a part of the coding, Corfiot, Fabio Piedimonte).
· Removed the upper limit on the number of time and space constraints.
· When modifying the days or hours, the affected constraints will be modified or removed, after confirmation from the user.
· Language change is activated without restarting.
· Many other interface improvements.
· Added a new sample file, by Silver.
· Improved the Morocco sample file and the Morocco instructions (by Liviu Lalescu and Chafik Graiguer).
May 27th, 2011· Updated to Qt 4.7.3.
· The generate multiple timetable dialog now shows max placed activities for the current timetable and for each timetable with time limit exceeded (suggested by Yush Yuen).
· Non-critical interface bug fix under Mac OS X: in the add and modify activity dialogs, the tab widget for the subactivities was too large, showing all the 35 possible components. Bug reported by Yush Yuen.
· Minor interface bug fix under Mac OS X: the dialogs now show minimize/maximize buttons. Bug reported by Yush Yuen.
· Minor improvement in the HTML exported timetables (multi-line comments look better), by Volker Dirr.
· Added a Galician translation, by Juan Marcos Filgueira Gomis (based on the Spanish translation, as of April 2011, by Jose Cesar Fernandez Lopez).

· Improved the Greek translation, by Dimitris Kanatas.
· Minor interface improvements.
· Added two new sample files, by Massimo Mancini and Dimitris Kanatas.
September 24th, 2010· A rare possible problem is improved (not completely solved). This problem was reported by Marco Barsotti: for some fixed timetables the generation may report incorrectly an impossible timetable. This problem cannot be solved perfectly, only patched, and this will hopefully solve the problem in all practical situations.
· An activity can now be split into 35 (it was previously only 10) - suggested by mohd on the forum.
· Improved a bit the add/modify activity dialogs (inactive tabs for the components of a subactivity are disabled).
· Updated the Slovak translation, by Ondrej Gregor.
· Added a new sample file, by Marco Barsotti.
August 12th, 2010· Speed improvement in the generation algorithm (this speed improvement is better observable as the number of hours per week is larger).
· Added a partial Hebrew translation, by Yotam Medini (only the main menu).
July 20th, 2010· Improved the random number generator, so that potential cycling problems are avoided (though probably nobody met such problems). The new random number generator has a much longer period and is better. The command line parameters for specifying the random seed are changed and you need to change your script if you use FET command line and if you want to specify the random seed. See the README file for the new command line parameters for specifying the random seed.
· Improved memory consumption on constraints activity/activities/subactivities preferred starting times/preferred time slots.
· Minor interface improvements.

· 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.

· Added Brazilian Portuguese translation (partial, incomplete yet), by Werner Bruns and Frank Martin.
· Added Danish translation (partial, only the main form and a few other forms), by David Lamhauge.
· Improved a bit the memory consumption.
· The tables contain now an -x(lowercase) if the teacher/students set/room is not available and -X(uppercase) for a break (suggested by George Miliotis). Also, you can configure separately if you want breaks displayed and/or not available displayed.
· Removed some useless messages, improving speed for some rare cases under GNU/Linux operating system and similar.
· Added a few new sample files (by Christoph Schilling, Horatiu Halmajan and aliponte).
· Changed default language/locale to en_US (instead of en_GB, which is non-standard).
February 5th, 2010· Crash bug fix for a rare situation, in which you have constraints (sub)activities preferred starting times or time slots and they refer to no activity (reported by George Miliotis).
January 30th, 2010· Updated to Qt 4.6.1 .
· Minor interface improvement: since a person reported he accidentally removed the basic constraints, it was added additional user confirmation for this, and more user information.
· Corrected a possible compiling crash bug under MinGW (this is not a FET bug, it is a MinGW bug). It was made a hack to overpass this bug.
· Improved export of timetable as CSV, by adding the id-s of the activities (suggested by m).
January 11th, 2010· Added Ukrainian translation (by Andriy Melnyk).
· Bug fix: when modifying the number of students in a students set, the related activities will show the correct number of students, but the generation will consider the old number of students until the user saves and loads again the file.
· Bug fix when adding/modifying a group's/subgroup's number of students, now all groups/subgroups with same name will have the same (new) number of students.
· Improved speed of loading for large files and blocked user input while loading a larger file, because otherwise the user could obtain an incomplete file (minor bug reported by Volker Dirr).
· Minor interface improvement: when exiting FET and choosing Save file, if you press Cancel, FET will not exit anymore reported by Soyeb Aswat
· Minor interface improvement: added a shortcut button to advanced functions in Time shortcuts section.
· Minor leak fixed (when removing a group or subgroup).
· Other minor bug fixes, when removing a group or a year.
December 16th, 2009· Added shortcut buttons on the main form (suggested by more users, especially: daviodan, Massimo Mancini, Paolo Cataldi). They can be deactivated from Settings Interface menu.
· Increased max activities to 15,000, max days per 'week' to 35, and other limits, and improved memory management. Now you don't need to have much virtual memory and memory usage is lower. This better memory management may bring a small slowdown of the generation, although in rare cases the new version may be faster. Speed variation depends also on the platform. More details about the possible slowdown: I compared times by starting parallel generations with the same random seed, which produces the same timetables in identical steps. I noticed usually less than 10% increased generating time, but in rare cases for some unusual files a bit more, maximum 17%. From the official examples, the worst situation is for the file Hungary/Bethlen/2007-2008-difficult/Bethlen_2007_2008.fet, with about 17% slowdown from FET version 5.11.0 to FET 5.12.0. I apologise for this "downgrade" of speed, but it is necessary.
· Updated to Qt 4.6.0
· Improved add activity dialog, by Volker Dirr: if in activities dialog, you select a filter and then try to add an activity, the values in this filter will be selected in the add activity dialog (this was also suggested by daviodan).
· Minor interface improvements.
· Changed help management (added links to online help).
· Corrected/updated translations.
· Code cleanup.
November 5th, 2009· 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.

August 24th, 2009· Added 2 new constraints: three activities grouped, max days between activities (suggested by Zsolt Udvari).
· Improved the names of constraints: "2" activities grouped, ordered and consecutive are now "two" activities grouped, ordered and consecutive.
· Code cleanup.
· Added a new Italian sample file, by Marco.
July 20th, 2009· Speed improvement if user has constraints activities same starting time, 2 activities consecutive and 2 activities ordered and activities not overlapping (idea and partial code by Volker Dirr). In some cases, the speed improvement is very high. This has to do with the initial ordering of the activities.
· Other minor speed improvements (idea and partial code by Volker Dirr).
· Added a Persian manual by Hamed SadeghiNeshat.
July 13th, 2009· Speed improvement if user has constraints activities same starting time. Idea and partial code by Volker Dirr.

· Added another sample file (by T. Renganathan).
July 2nd, 2009· Leaking bugs fixed (closed Qt widgets were not removed).
· Bug fix in generation algorithm. This bug is not seen in practice, but the code in generate.cpp was incorrect in a minor portion. Specifically, it corrected tests done when the user has constraints of type students early max beginnings at second hour, without max gaps per week for students, with max or min hours daily for students.
· Added constraint teachers max days per week (suggested by Marco Barsotti).
· Made the results directory customizable (user can choose it) suggested by Massimo Mancini. Important: under Windows, the default location is not the usual one, but $HOMEfet-results (C:Documents and Settingsusernamefet-results or C:Usersusernamefet-results)
· Fixed a bug: if user deactivated some activities, in some cases he could not generate a timetable (if using preferred times for (sub)activities).
· Added a filter in add and modify dialogs constraints activities not overlapping (suggested by Yush Yuen).
· Added a new feature in the timetable generate dialog, which allows you to see the time when the highest number of activities was placed (suggested by Yush Yuen).

· Improved compilation time and memory consumption by modifying the data reading and parsing routines (additional checking/tests needed here).
· Minor memory leak fix (normally, not noticeable).
· Minor interface bug fix (description of constraint teacher max gaps per day displayed incorrectly information about the gaps, writing "per week" instead of "per day").
· Modified the order of search for translation files (firstly in current directory, then in current directory/translations, then, under Unix-like, in /usr/share/fet/translations).
April 10th, 2009· Added constraint activity tag preferred room(s) - suggested by Horatiu Halmajan and Catalin Maican

If you want spreading for these activities, you need to manually select this option.
· Arabic translation update by Hatim Alahmadi
October 13th, 2008· Added 2 more samples by Cristian Balint
· Small bug fix in statistics exported as html, by Volker Dirr
October 7th, 2008· Added an option to remove redundant constraints

August 18th, 2008· Added constraint teacher(s) and students (set) interval max days per week, to specify an hourly interval and the maximum number of days per week for teachers (students) to work in this interval. This constraint is very useful, for instance specify that teachers and students must not work more than 2 times per week in the last hour of the day.
· Added constraint a set of activities end students day to specify for a group of activities that they should end the day for students (for instance for meetings with the class master).

· Allowing more constraint activity preferred starting times (or preferred time slots) for same activity id, which was restricted by a bug to only one. You can add more constraints with different weights.
June 19th, 2008· Bug fix - when saving a timetable, regenerating it might give an impossible timetable - reported by Yush Yuen.
· This bug solved other possible important bug (I doubt someone observed this bug. What happens: if an activity has a fixed time, then when FET allocates it it fixes a room for this activity and consequent changes are not possible to reschedule this activity to another room - might give impossible timetable in extreme cases). Now it is possible to reallocate the room to another slot.
· Improved add activity dialog - if min days is x (greater than 1) and weight is lower than 100.0%, user can add a second constraint with x-1 min days, to ensure activities are better separated.
· Added advice to remove redundant min n days constraints when adding same starting time constraints.
· Added another sample by Yush Yuen.
June 12th, 2008· Bug fix - now inactivating some activities allows to generate the timetable, because constraints referring to these activities are ignored
· Improvement - activating/deactivating activities for a year/group considers also the activities of included groups/subgroups
· Added 3 more samples (from Namibia)
· Arabic and Greek translations updates.
May 29th, 2008· Arabic, Romanian, Spanish, Italian translations update.
· Added an option to select all slots available or not available for constraints break, not available and preferred times (suggested by didit).

· Indonesian, Spanish and Arabic translation updates
· Added an additional check for inconsistency
April 7th, 2008· Greek, Romanian, Spanish translations updates
· Small interface improvements

· Added more tests to ensure home rooms inputted correctly
· Generating multiple now saves each timetable in .fet form (suggested by kdsayang)
· Increased number of days per week to 28, to allow exam scheduling (suggested by kdsayang)
March 31st, 2008· Crash bug fix - when adding a year with same name as a group or subgroup
