New 3D effects like Fog; Improved Android keyboard handling; Bug fixes.
Good to know :). I have a bug report here: github.com/Scirra/Construct-3-bugs/issues/5247
If you want to add your findings there, feel free :). There's been a couple other folks who posted regarding other Addons/Plugins as well. So, Ashley probably already knows it's affecting most, if not all of them.
