Finally, the new SCARM v. 0.9.24 is ready and published, coming with the long-awaited feature for true roads with grades and various surface markings! See more about it in the following blog post:
This version has also new and updated O-gauge track systems, favorite library buttons, many bugfixes and more. Hope you will like it
Please note that the new version has many parts with rewritten code due to the new roads feature and this may lead to some new bugs, no matter that I tested it more than a month. If you encounter a problem, write about it here with the steps that will allow me to reproduce and check it.
@Jo: You can try to run SCARM on a Mac even now with some special tweaks - read about that here: Running SCARM on Apple Mac
