It's been a while since I used OS and E+ and I'm a little at lost with the latest versions of softwares. I understand there have been 2 releases for OpenStudio: One for the SDK by the NREL and one for the application by the Coalition.
If I understood correctly, OS 2.9 is the last release thats works with Sketchup Make 2017. The more recent versions work with different versions of Sketchup Pro. With a 2022 Sketuchup Pro licence I could use the O.S. Application 1.4 , O.S. SDK 3.4 and E+ 22.1
I don't use Euclid a lot, but I understand it could work with SketchupMake 2017 and EnergyPlus up to 9.5.
I just want to clarify, we went from E+ 9.6 to 22? As in a change of nomenclature for the year 2022? Or is it two branches of releases? Because I saw some pre-release of newer 9.6 on Github.
