Stable release: 3D model; Dynamic sampling; New fullscreen modes & loads more.
In the next update, I'd like to see a setting that allows saving window positions. For those who use multiple monitors, as is my case (I use three), every time I open Construct I have to manually rearrange the windows on each monitor to the positions I usually use. This ends up being quite inconvenient, since I have to repeat the process every time I start Construct 3.
There's already support for restoring windows across multiple monitors. Try clicking 'Enable multi-monitor features' in Settings.
