No. Checkpoint files ( .chk ) remain compatible across minor updates. Major revisions (e.g., Rev A.03 to Rev B.01) may break compatibility – restart jobs from the last .rwf or reformat .chk files.
It is vital to prioritize the official 64-bit version to leverage the full power of your modern hardware. While the integrated Windows interface provides great convenience for teaching and testing small systems, users planning heavy-duty research projects should be aware of its performance bottlenecks and consider using the Linux version via WSL or on a dedicated cluster.
