OpenVSP 3.32.2 Released

While 3.32.1 fixed the most egregious issues with 3.32.0, it was still a bit of a hot mess in its own right. This release helps tame the chaos, hopefully it gets people back on track.

Of course, I couldn’t help myself and stick to _just_ bug fixes. So, if you use CFDMesh & Co, you will find that the ‘f’ and ‘r’ keys work like they do in the rest of OpenVSP. These are UX candy — go ahead and indulge.

(For those of you that are wondering what pressing ‘f’ or ‘r’ does — try it! If you can’t try it right now, pressing ‘f’ will ‘f’it all the visible stuff onto the screen by auto zoom, pan, and setting the center of rotation. Pressing ‘r’ presents a bunch of green points. Click one and it will be set to the center of rotation and moved to the center of the screen.

Other than that, it should mostly be a bunch of fixes. The migration from sprintf to snprintf broke a few things. Those have been fixed and an audit has been conducted, so hopefully we’re through with that.

Fix lingering problems with CompGeom half meshes and tag files. Previous fixes broke things like Wave Drag and Parasite Drag.

Fix error validating subsurface structures properties on structures data transfer. Was preventing analysis of structures with subsurfaces. Improve error messages while we’re at it.

Attempt to set property length unit when converting an old file. Unfortunately, I can’t see a way to convert

Some of the VSPAERO output files were updated, our parsing of those files has now been updated to match.

Fix some small VSPAERO issues that were causing hangs and crashes when slicing planes were active.

Overall, not a ton of stuff — but everyone should update because the problems these fixes address were hitting a bunch of users. Hopefully we’ll keep things under control for a while going forward.
