This update was pushed up last night, the changes are:
Juicier explosion & destruction graphics
Improved crafting material pickup graphics
Shields nurfed
Shields have also being nurfed a bit, so it'll be easier for you to take down enemies with shields, but a little harder to stay protected with shields. This should balance the late-game gameplay a little better.
Miscellaneous
Finally to pick up materials in craft mode the button has been changed to right mouse the same as melting.
