- New versioning system: now the "dev" versions are 1.1.x (now, 1.1.50),
while the "official" versions are 1.0.x
- Settings for the visual mapping are added only if no setting was
already present. Apart from the node lablel, where the default is to
show the ID and we want to show the canonicalName instead
- Edge and node dialogs now allow to insert the description of an
edge/node, which will then be shown as tooltip
- Graphs (in "developer" mode) have now the option to "Render to
JPEG...", which allows to have the graph rendered (with current zoom
level) in a jpg image of given size. For this, a menu item to show the
current zoom level has also been added
