Minitab crash-recovery prompt skipped after version upgrade: does the auto-save interval change which .MPJ state gets restored?

Restoration behavior after a Minitab version change
After moving a project workflow to a newer Minitab release, I want to confirm how the automatic backup and recovery mechanism decides which project state to offer at restart. My understanding is that Minitab writes temporary recovery files while a project (.MPJ) is open, and after an unexpected close it prompts to restore the most recent auto-saved version, recovering the whole session (worksheets, graphs, results) rather than individual datasets.
Constraints and uncertainty
The auto-save interval is configurable, so the restored state can lag behind the last manual edits. I also understand recovery files are transient and may be removed by cleanup tools or overwritten by later saves. What I cannot confirm from documentation is whether the recovery prompt and interval behavior changed between releases, and whether there is any integrity check on the restored file.
Questions
- Does the recovery prompt always offer the latest auto-save, or can an older recovery file be selected manually?
- Has the default auto-save interval or recovery-file location changed in recent Minitab versions?
- Absent a built-in checksum, what is the recommended way to verify a restored .MPJ matches the pre-crash state?
