OpenVSP 3.20.1 includes a few bug fixes. Most importantly, one that fixes a problem introduced in 3.20.0 that causes some models (saved in 3.20) to open up wrong. The other bug fixes are a bit more longstanding and subtle. But there is nothing to be scared of — everyone should update.

Bug Fixes:

• Wing projected span as Parm did not have unique name.
• Number of sets assumed in some GUI’s not updated for recent expansion
• Error in Bezier evaluation (Code-Eli)
• Error in surface point projection (Code-Eli) will help intersection code
