Does Bentley provide free Microstation for testing and maintenance of freeware?

Hi,

I've developed a Vehicle Turning Simulation for Microstation as freeware (https://glamsen.se/MSTurn_2.htm). I was using my work-license of Microstation for developing and now I'm about to retire from work. However I still want to provide users with my freeware without buying a expensive licens for testing and maintenance.

Anyone heard about a limited Microstation versions other than trial versions?
