New Features

Support for freeform text in classes

Properties or methods are not enough or maybe you need more expressive member definitions? No problem, just use the new free form text tool to enter any text you like. Freeform texts work like any other members, except that there are no constraints regarding their content, just write anything you like.

Undo Delete Operations

All delete operation can now be reverted by just pressing CMD+Z or CTRL+Z (or choosing the relevant menu entry from the Edit menu).

Properties to Relations

You can now convert properties to relations and vice versa with a just simple click: Select one or more properties and choose the desired connection type from the context menu and that's all! The same also works the other way round: Simply click on a relation to convert it to a property.
