**Mac & Linux version**

Yes, aSc TimeTables & aSc Substitutions are now available on Mac and Linux systems. You will soon be able to download the instalation for each platform from our main download page. No emulator or windows license is needed. You can of course share your timetables between platforms.

**Improved generation speed**

The software now generates around 10% faster on the dual/quadcore systems due to improvements in the communication between cores.

**Room priorities**

It is now possible to specify for each lesson the ideal, not-so-best and use-only-in-emergency classrooms. You can exactly specify how many times per week kids can be in the best room, how many times you will tolerate usage of the emergency room:

Optimizing the room usage for students

There are now a few new rules that allow you to reduce the room usage to save on cleaning or rent the rooms:

Reducing the room usage

**Cardrelationships for groups, subjects, teacher's classes**

you can now apply all cardrelationships to groups. So for example you can define cardrelatioships that will only affect girls from 5A.

**Simplified Import from Excel/Clipboard**

It shall be now much easier to import basic data as well as lessons into the software. If you are importing lessons/seminars, you no longer need to have the timetable with subjects/teachers, the software can import all the data in one step.

Importing from Clipboard (MS Excel)

also the import of students and selections was simplified:

Import sections from clipboard(Excel)

**Max teachers on one period**

You can now define the maximum number of teachers on certain periods to make sure you have enough free teachers free on each period.

We need two free teachers on each period to make sure we have enough teachers for substitutions

**Subjects/courses distribution during the year**

You can specify that student has to complete Course A before he can have course B.

Student has to finish Biology before he can attend Biology practice

Also for the multiweek timetables it is now possible to specify that subject has to be on consecutive 4 weeks.

Subject has to be in consecutive weeks/terms

**Importance of cardrelationships**

It is now possible possible to specify the importance also for regular cardrelationships.

**Importance of constraints**

For some constraints you can set the importance directly when you specifying this constraint. So even if you run the generation with relaxation allowed you can specify that this constraint shall not be relaxed.

**Student group changes**

If you allow it, the generator can swith the student to different section between terms.

**Other small improvements**
