FET-5.24.0 released

[Liviu Lalescu]

On Tuesday, 30 December 2014, FET-5.24.0 was released. From the ChangeLog:

    - Updated to Qt 5.4.0.
    - Significant speed improvements when using many students sets (suggested by Volker Dirr).
    - Speed improvements in the statistics menu.
    - Other speed improvements for larger data.
    - Added an option to hide students subgroups in combo boxes/activity planning (useful if you have too many students subgroups and you don't use them in the interface).
    - Added options to select the categories of timetables to write on the hard disk.
    - Automatic division of years by categories is improved (suggested by alxgudea, Bobby Wise and Volker Dirr).
    - Code improvement in reading the .fet XML files: converted from the obsolete Qt classes QDom* to QXmlStreamReader. It brings speed and memory improvements when reading the input files, and ensures FET source compatibility with future Qt versions. Also error reporting when reading a corrupt file is improved. The structure of the .fet XML files is slightly changed, but of course older files are opened correctly.
    - Several bug fixes, when trying to open corrupt files.
    - Other bug fixes, reported by Vanyo Georgiev.
    - It is now allowed to have constraints preferred/home rooms with a single room (suggested by liquid and Volker Dirr).
    - Added a new example file from Vietnam, by nguyenhuuduyet.
    - Added a new example file from Namibia, by Bobby Wise.
    - Added two anonymous example files.
