Platform Upgrade to .NET 10:
Version 15.20 moves Software Ideas Modeler to .NET 10, ensuring better performance, long-term platform support, and improved compatibility with modern systems. This upgrade lays a solid foundation for future development and enhancements across the application.
Harmonize Diagram Layout:
A new Harmonize Diagram Layout feature helps bring visual consistency to your diagrams. With a single action, element placement and spacing can be aligned more uniformly, making diagrams clearer, cleaner, and easier to read—especially in large or evolving models.
