We are happy to present our new release! We worked a lot on optimisation: in some specific situations memory usage was decreased up to 80 times: from 160 Mb to 2.1 Mb! Also now you can try out new DOF with awesome Bokeh feature. And as always there is even more to it: for example, Doppler effect and Multitouch support. Check out the release article for more!
