Hello Community! 
With every new version of SPS Software (like the recent 25.2), we publish detailed Release Notes. Here is a quick guide on how to scan them efficiently and spot what actually impacts your projects.
1. Where to find them?
You can find the release summaries pinned in the Announcements category here in the community and in the Official Documentation.
2. The Version Numbering
Understanding the numbers helps you navigate updates:
- Major Releases (e.g., 25.2, 26.1, 26.2): These align with MATLAB release cycles and typically introduce major updates, new features, and library improvements.
- Minor Updates (e.g., 25.2.1, 25.2.3): These typically introduce significant added value, new features, and library updates.
- Maintenance Updates (e.g., 25.2.0.15): The last number indicates minor bug fixes or patches.
Backward & Forward Compatibility
We want to ensure both backward and forward compatibility for your models.
The worst that could happen when opening a model saved in a newer version (e.g., 26.1) in an older version (e.g., 25.2) is a “missing link error” in Simulink, specifically if the newer model uses a block that didn’t exist yet in the old version.
