OpenVSP 3.13.2 Released

We’ve had trouble updating the website, but now have a workaround until we can get a proper fix. Sorry for the trouble.

Just in time for the workshop an update with some features and lots of bug fixes.

This adds a built-in body of revolution — in case the Duct custom components were not enough for your needs. Also includes Spin control for fuselage and stack geoms.

Lots of updates to VSPAERO — ground effect and some viewer updates, but mostly a whole host of bug fixes for issues that people have been running into.

Plenty of good stuff here. Everyone should update.
