On Sunday, 13 June 2021, FET-6.0.4 was released. From the ChangeLog:
- Updated to Qt 6.1.1.
- Bug fix in the timetable generate multiple dialog, when generating on multiple threads: if the generation time limit was reached and if the limit on the total number of generated timetables was reached, the highest-stage solutions of some of the timetables generated in the last round were missing in the final results.
