This release contains fixes for several issues, not all of which I can remember.
The biggest is a fix that ensures the plugin's temporary directory exists before trying to create a new tower model.
Also there is now an option to limit the length of file names to prevent issues with some printers.
As usual, there are some other fixes behind the scenes.
I have many more enhancements that I would like to add, but time will tell if I get a chance.
