We have taught our program to automatically save all changes in a project, so you will no longer have to check whether or not your project has been saved.

The second, not a less important feature, is undoing last actions (Undo\Redo). That means you can now take any actions over your project and not worry for your data, as everything can be easily restored.

The rest of the changes primarily apply to the internal functioning of the program and eliminating errors found.
