- Crash bug fixed (in the Mornings-Afternoons mode), if using constraints of type students (set) min hours daily with min hours = 1, together with constraints of type students (set) min mornings/afternoons per week. - The constraints of type teacher(s) min hours daily will now allow the value 1 for min hours (suggested by ngoctp29121982, and maybe by other users in the past). In this way you can add the constraints teacher(s) min 1 hours daily, and teacher(s) min 2 hours per morning, and it is now allowed to have only 1 hour per afternoon (the constraints of type min hours per morning/afternoon require you data set to also have the constraints of type min hours daily for the affected teacher(s)). - Interface improvement: if an activity does not have any allowed slot, FET will report its ID, as before, but also its detailed description (suggested by GUEFFAZ REDA). - The majority of the dialogs will now have a size grip (a handle to resize dialogs, usually located in the bottom-right corner of the dialog), for easier resizing (suggested by Michael Towers' report that some dialogs have a too small initial dimension). - Minor improvements in two English text fields (suggested by Vangelis Karafillidis). - Corrected the Arabic translation, by Benahmed Abdelkrim. - Corrected the Romanian translation, by Liviu Lalescu. - Improved the Greek translation, by Vangelis Karafillidis.
