This was a feature of SNOPT meant for the user to perform any finalization and clean up, and write out any necessary files prior to the end of the program. However, this option was never provided to pySNOPT users, and therefore has been disabled. This will reduce the number of function evaluations for every optimization by one, with no impact on the final result. **However, the user can no longer rely on using `db[db['last']]` to retrieve the optimal design, since it may not be the last function evaluation.** The optimal design vector is stored under the key `xs`. \ No newline at end of file
