Things I like about UE4 4.2 Update
The keys Alt+[ and Alt+] adjust the size of the transform gizmo.
You can now use an actor picker to choose which actor to attach to another.
You can now choose where to place a class added via the New Class Wizard.
You can now import OBJ mesh objects.
There is now a filter that hides actors that are not in the current level.
There is now a menu option for scene outliner folders to select all the actors within that folder.
Users can now create a blueprint function library asset! This allows you to create a nice library of Blueprint functions that can be used throughout your project!
You can now draw Canvas UI straight to a texture, and then map that texture to objects in your scene! (Thanks to James Tan).
There is a new experimental plugin available for the Math Expression Node for Blueprints. This node enables you to simply type in an expression and it will make the input pins, output pins, and a collapsed graph that contains your math expression. To use this node, simply activate the Math Expression plugin in the plugin manager. It will then appear in the right click context menu of the Blueprint Graph Editor. Once created, type in your expression. If you make a mistake, you can edit the expression by renaming the node.
