New features

We have added an indicator that shows if a new version is available. You can now easily download and install a new version of twin.
When twin is unlicenced, a licence request window is shown
Parameters for changing the solver iterations for position and velocity of the rigid body simulation are added to the settings window
The camera projection mode can now be switched between Perspective and Orthographic
PLCConnector: Driver for Rockwell/Allen Bradley PLCs added

Script: The name and datatype of inputs and outputs are now defined by InputDefinitions and OutputDefinitions
Script: Using-statements within scripts can now be placed in the region Usings
Script: Use BeforeSimulationStep instead of AfterInputChanged as default running type for new scripts
PLCConnector: When the connection to the PLC is established, while the simulation is running, all inputs are written to the PLC
PLCConnector: When outputs of a PLCConnector are not available, an error is now shown in the prperty grid.
PositionTracker: Choose the reference frame for the position output

Fixed an issue which causes twin to crash, when simulation components are moved in the diagram with the CTRL-key pressed
In the orthografic camera view, 3d objects could not be moved via mouse
Fixed an issue which prevent reseting the outputs of a PLCConnector on simulation reset
3D-Objects, which are deleted because they are out of world bounds are restored correctly on simulation reset.
The message box of unhandled exceptions is now allways shown on top
Fixed a memory leak in the PhysX physic engine
Fixed an issue which causes that the PLCSIMAdvanced driver could not be used more than one times
