New "more" option to access the whole list of design codes
The More codes… button used to search codes in former versions of Robot, was replaced by a More link, directly accessible from the codes drop-down lists.
To access this option, click Tools 
Job Preferences Design Codes, and then click any of the arrows to open the list of available codes.
Global mode elastic instability multipliers acr calculation for building type structures
The elastic instability multipliers acr can now be inspected among other story results, independently for each story, direction X, Y, and load case/combination.
This factor is an important measure of the frame sway-sensitiveness, and it is defined by the point 5.2.1 (4)B of the EN 1993-1-1:2005 code.
Optimization of the dynamic update when local coordinate systems are displayed
The new schematic presentation of the local coordinate systems allows a smoother and faster display of the model.
In former versions, displaying the local coordinate systems could slow down graphical operations such as rotation and pan, especially on large models.
Transmit loads from claddings to nodes only
It is now possible to transfer the loads from the claddings to the structural elements.
This can be done through the generation of nodal loads in the cladding vertices.
