FET-5.40.0 released

[Liviu Lalescu]

On Thursday, 3 October 2019, FET-5.40.0 was released. From the ChangeLog:

- Updated to Qt 5.13.1.
- Added virtual rooms, which give the possibility for the user to specify more rooms for an activity, or to choose between a large room or more smaller rooms for an activity, and might open the possibilities for other kinds of usage. Suggested by math on the forum, who had some very useful ideas. These users also suggested more rooms for an activity: Volker Dirr, Anton Anthofer, dasa, sln_rj, and amin. Unfortunately, this feature might make FET about 5-10% slower even if you are not using virtual rooms, and I apologize for this, but virtual rooms are useful.
- Added the possibility to allow a one day exception of max span plus one for the constraints of type teacher(s) max span per day (suggested by totera, Luca, and bachiri401).
- Bug fix: now it is not allowed to run FET command-line on files which do not contain any activity.
- Minor bug fix when using constraints with weights having 5 or 6 digits after the decimal dot (like 99.999975%). This minor bug did not affect the generation, only the final report of the (soft) conflicts.
- Minor bug fix in the import of the rooms and of the buildings, by Volker Dirr.
- Added a new example file from Romania, by rapsy.

A big "Thank you!" to the collaborators who made this FET release possible.

Unfortunately, I found a bug which needs to be solved as soon as possible. I might release today 5.40.1. If using virtual rooms and locking timetables, some activity preferred room constraints might be added more times.
