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).
The macOS version of FET-6.7.3 is now available.
