We are excited to announce that OCCT 8.0.0 is planned for release in the first quarter of 2026.
This release marks a major milestone for Open Cascade technology. While improved speed is a major focus, version 8.0.0 is also a huge step forward for stability and long-term maintainability, providing a robust foundation for future software development.
A New Standard for Performance: We have focused heavily on general algorithmic optimization to handle complex cases more efficiently.
- Significant Speed Gains: The overall performance of our algorithms has been improved substantially.
- For Example: To illustrate these gains, STEP reading has improved by up to 75% compared to version 7.7.
- Wider Impact: These optimization efforts also positively affect other readers, including DXF, SAT, and Parasolid.
For Added Value Component Users: If you utilize our Added Value Components, this is the ideal time to extend your maintenance contract. Securing your maintenance now guarantees you access to the new release, ensuring your applications benefit from these performance and stability upgrades immediately.
Note: OCCT Added Value Components remain royalty-free, permanent, and licensed per application (not per user).
Expert Migration & Development: Upgrading to a major release ensures your software remains competitive, but migration can be complex. We are here to support you:
🔹 Commercial Consulting: We provide strategic advice on migration paths.
🔹 Custom Development: Our team can handle the development required to upgrade your applications to 8.0.0.
