Better SVG rendering
This is a significant improvement. With Sirius 4.0, on a diagram when the user uses the zoom, the rendering of a SVG file has a much higher quality.
Contribute SVG shapes
Sirius provides a basic image style for node mappings, which offers a selection of five different shapes. The new bundledImageShape extension point allows specifiers to provide their own shapes defined in a SVG file like a stencil pack.
To catch all the new features coming with Sirius 4.0 have a look at the slides of our talk at EclipseCon France! Another chance for you to join the Sirius community, SiriusCon will occur in Paris the 15th November 2016. Be sure to save the date!
