OpenVSP 3.26.1 Released

If 3.26.0 wasn’t new enough for you, here is one better. No new features here, but a couple of bug fixes that are pretty essential.

If you weren’t on 3.26.0, you should because it has lots of good stuff, If you’re on 3.26.0, you should move to 3.26.1 because it has some important fixes.

Most importantly, a list-moment change to 3.26.0 disabled a few buttons and other things in the GUI — Wing Airfoil Copy/Paste, changing which Prop Curve you were editing, and two new Prop curve features Approximate All and Reset Thickness. These fixes alone are worth the price of admission.

In addition, I’ve finally (knock on wood) fixed the issues that were making actuator disk not work from the GUI with thick-surface files, thin-surface via the experimental format, and general odd behavior when using the Shown set.

Plus a fix for a bug that might be impossible to hit.

Also, some more spelling corrections from Luz Paz — for people who care about spelling errors in the comments of source code. Is my mother watching? Thanks for the contribution.
