Hello,

There are many users requesting an undo system.

It might be possible something ugly: save the whole current data file in memory, maybe archived with gzip (something very fast). I can see that an ~8 MB file (very large) is archived to ~250 kb. Assuming an 100 operations history, this would occupy 100 * 250 kb = 25 MB of memory, not too much.

What do you think?

Of course, even such a primitive undo system would be quite difficult to add, but much easier than a good one, which only records the operation.

On Sunday, 8 January 2023, FET-6.8.0 was released. From the ChangeLog:

  - Added an advanced filter in the activities/subactivities dialog (similar to the existing advanced filter in the all time/space constraints dialog). Also, it is now simpler to activate/deactivate the (sub)activities in these dialogs - there were added activate/deactivate buttons, such that it is no longer needed to enter the "Modify (sub)activity dialog". Also, it is now possible to activate/deactivate with a single button all the listed (filtered) (sub)activities. Also, in the all time/space constraints dialog, it is now possible to activate/deactivate with a single button all the listed (filtered) time/space constraints. Suggested by Horațiu Hălmăjan, Yush Yuen, Constantin Romulus, Nguyễn Hữu Duyệt, noddy11, Anthony Siaudeau, Vangelis Karafillidis, and Liviu Lalescu.
  - Various improvements and minor bug fixes.
  - Updated the Romanian translation, by Liviu Lalescu.
  - Updated the Greek translation, by Vangelis Karafillidis.
  - Updated the French translation, by Pascal Cohen.
  - Updated the Arabic translation, by Benahmed Abdelkrim.

  - Minor improvements.
  - Code cleanup.

On Thursday, 8 December, FET-6.7.6 was released. From the ChangeLog:

  - Interface bug fix: in the activities dialog, in the list of the related space constraints for the selected activity, the constraints of type teacher/students set home room(s) which affected this activity were not shown. Reported by giardiniere and Volker Dirr.

  - Minor corrections.

Welcome the new server from https://hosterion.ro/ and https://hosterion.com/ . Things should be faster and better now, hopefully, and at a smaller price. The server is physically placed in Amsterdam, as recommended by the host (since there are many downloads in Europe and the whole world, not only from Romania).

Please let me know if there are any problems. The propagation of the nameservers is not yet perfect, but should be perfect in a few days.

On Tuesday, 29 November 2022, FET-6.7.4 was released. From the ChangeLog:

  - Added the possibility to select, in the Mornings-Afternoons mode, instead of min days between activities, the number of min _half_ days between activities, when adding activities from the interface or when importing them from CSV files (suggested by ngoctp29121982, who's advice was very useful). The export of the activities to CSV files in this case is also updated (if there are constraints of type min half days between activities, they will be exported in a format compatible with the importing).
  - Code cleanup.

Personal thanks go to ngoctp29121982, for his useful advice and testing.

There is a new test version, here: https://lalescu.ro/liviu/fet/download/test/

On Thursday, 24 November 2022, FET-6.7.3 was released. From the ChangeLog:

  - Bug fix: when generating an impossible file on multiple threads, the program could hang (discovered with the help of math). The bug was isolated with the help of GDB (GNU Debugger).
  - Improved the generation on some locked timetables for which the program would report impossible generation, even if these files were solved when they were unlocked (reported by math).

On Saturday, 19 November 2022, FET-6.7.2 was released. From the ChangeLog:

  - Updated to Qt 6.4.1.
  - Minor improvements.
