What's new in 20-sim?

General Features

• Both the model (.emx file in 20-sim 3.x) and the experiment (.exp file in 20-sim 3.x) are now stored in a single file. To distinguish this file from 20-sim 3.6 files a new extension (.emx) is used.

• 20-sim 4.0 runs faster and runs on Windows Vista.
•  You can change the display language.
