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](https://community.opal-rt.com/c/announcements) category here in the community and in the [Official Documentation](https://opal-rt.atlassian.net/wiki/spaces/PSPS/pages/1857421334/Release+Notes). ### 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. * * * _Have a question about a specific release note item?
