Nevertheless, V15.2.1 is not without limitations. As of today, it lacks native compatibility with 64-bit processors for handling extremely large models, has no direct cloud collaboration features, and its API (Application Programming Interface) for custom scripting is less robust than in version 18 or 20. Engineers must also contend with file format obsolescence; models saved in V15 cannot be opened in versions older than V15, and opening them in newer versions often requires a one-way migration.
