- Critical interface bug fixes: When removing an activity tag in the constraints of type teachers/students max activity tags per day/real day from set or modifying/removing an activity tag in the constraints of type room(s) max activity tags per day/real day/week from set, the constraints were not correctly updated (reported by Yush Yuen). - Improved the English text - instead of 'he', 'his', and 'him' pronouns when referring to a teacher, we use 'he/she', 'his/her', and 'him/her' (suggested by Alexandre R. Soares and Andrea Primiani). - Improved the symbol for the 'not available' cells in the constraints of type 'not available' or 'preferred times' - it is now '✗' instead of 'X'. Also, the description of the deactivated activities and constraints now begins with '✗' instead of 'X'. - Added a Help button in the days and hours dialogs, for guidance; this is useful in modes other than the Official one (suggested by LEOBASSARTS). - Added the option to order the activities in the timetables by the tags, if a table cell contains more than one activity (suggested by Benahmed Abdelkrim; Volker Dirr suggested to consider only the printable tags). - Minor fixes. - Updated the Spanish translation, by Li Chong, who is the newly assigned translator. The Spanish translation is now nearly complete. - Added a new example file, by Benahmed Abdelkrim.
