GanttProject 2.8.4 greatly improves user interface scalability which makes easier the life of happy owners of Macs with Retina screens, Microsoft Surface Pro devices and other high-density displays.
DPI configuration option which was introduced in GanttProject 2.8.3 is now considered in almost all parts of the user interface, including toolbar icons and milestone and arrow shapes on Gantt chart.
Unfortunately apps do not know the physical size of the screen and pixel density, so users need to configure DPI setting manually. Most of the mere mortals will want to leave the default value 96. Those who use High-DPI screens should set the value appropriate for their screens. Most likely values in [150..200] range will be fine. Changing the option value is safe, it just scales fonts and graphics in GanttProject linearly. Play with the option and choose the best value for your screen.
We recommend restarting GanttProject after changing DPI option value
The list of closed tickets is available on release milestone page
Also, iCal import plugin configuration was fixed and it doesn't need any hacking anymore.
