Dymola 7.2 is now released. There are many enhancements and extensions, for example,

Vehicle Dynamics Trucks: covers combinations such as trucks with full trailers and tractors with semi-trailers. The component set is complemented with models of air suspension, liquid loads, twin tires, and more.

Vehicle Dynamics Drivelines: makes it possible to study the interaction between the driveline and the chassis on a more detailed level; including wind-up, joint-bending, reaction forces and torques.

Modelica_Fluid library: contains components describing 1-dimensional thermo-fluid flow in a network of components and pipes.

Improved authoring of Modelica text: In particular, the Insert Function Call command allows browsing for functions and then entering the arguments, for easy insertion of a function call.
