I would like to ask the developers how the work on implementing foam and splashes support from phoenixfd is progressing, can we expect it in v6?
Is there hypothetically a technical possibility to implement motion blur support for a changing topology or to create a separate CoronaMesher that works with motion blur?
Soon I will have to render some fountains and I would not want to use other engines, since I stuck to Corona.
From what I know (maybe I’m wrong) , we need to wait Chaosgroup to implement the right API to be able to render foam with Corona.
Those two things you mentioned here (foam and motion blur for changing topology) are extremely tricky. The current status is: we are aware that this is very important to many users, and it is high priority to us. Can’t provide any time frame right now, though.
Yes, the motion not working with changing topology is a big problem for us. We have had to bail on using Corona for certain projects which makes me sad 
I second the need for motion blur with changing topology, let’s not wait much longer if possible.
done (at least the first 2)
