Thanks for the update on steam!
Very minor discrepency I've noticed with alterable values:
If you enter a calculation though which would result in a decimal value, the value is converted into an integer, e.g. entering 5/2 gives a result of 2
but if you enter a decimal value/floating point number in an active object's alt val field in the frame editor, the field continues to display the value as a floating point, though it is treated still as an integer during runtime or once you change focus. (I assume the properties window not supporting floats is intended behaviour since this happened in older versions as well).
Another small thing with alt vals that also happens in earlier versions: if you change an active object's alterable value in the frame editor and then click on a different editor such as the event editor, the changes to that alterable value are not saved - you have to either press enter or change which object has focus for the changes to save
