Not really a daily build feature, since Corona 10 is already released, but we didn't have a dedicated playground thread for this, and we are super curious about your results, so here it is!
If you are rendering a scene where highlights are blurred due to depth of field (distant city lights, interior lighting, reflective/refractive objects), you can enable the new DOF Highlights Solver to get faster rendering.
You will find the checkbox in Render Setup > Performance > Performance settings. You don't have to change the Budget and Reprojection values as the defaults work well (but you are welcome to test them if you wish!).

You also need a camera with depth of field enabled.

I'm curious to see other's results too. I did test this feature briefly and found that in some situation it gave very impressive improvement, but in other it made noise significantly worse and also trying to DOF solver settings produced counterintuitive results. Unfortunately i didn't save the scenes, nor did i try the solver on other scenes, so it would be interesting to hear what others find about it.

Perhaps you were trying it during the daily builds phase? We had some similar results in our internal tests, but all of that was fixed in the final V10. Of course if anyone is getting worse render times or more noise with the new DOF solver enabled, please let us know! (and preferably share scenes)

Yes indeed i think it was one of the first builds with the new feature. Glad to hear that some issues were fixed, i will definitely give it another try sometime soon.
