OpenVSP 3.20.0 Released

OpenVSP 3.20 just in time for 2020! Start off the new year with a new version with one really cool feature (Smart Input) and a bunch of fixes.

Overall, this update is very small. It wouldn’t cause a .20 bump except that the new feature also adds a new library dependency and that warrants a little more attention.

You may be asking, “What is Smart Input?”. Input boxes (the white box with parameter values) are now smarter. They can now can do simple math (+-*/^).

Maybe you want to nudge a parameter by 0.375 — just click in the input box and put ‘+.375’ after the current value. Maybe you want to double something ‘*2’, increase by 10% ‘*1.1’, convert units on the fly ‘/2.54’. This is a really handy feature that will find many uses.

In addition to Smart Input, there are a handful of build fixes, code cleanups and improvements to the automation of the build process.
