So if I want to support both Rhino 6 and 7, I need to install Grasshopper nuget package 6.x?
Does Grasshopper in Rhino 7 can load plugins compiled with nuget Grasshopper 6.x?
Is there any rule of thumb when deciding compatibility (breaking changes in certain version, etc.)?
If you want a single Grasshopper plug-in assembly to load in both V6 and V7, then yes you will need 6.x NuGet package. Iād recommend just using 6.35 since this is the latest and last Rhino 6 service release. If customers are not using this version, then they should upgrade.
