If you haven't seen it, GPackage (https://gpackage.io) manager is a new package manager that has a tremendous amount of promise. It offers the ability to install different versions of the same package simultaneously to a version of LabVIEW. This allows the creation of "sandboxes" where on a per project basis I can tightly control which version of software I'm using. Another way of saying it, I can prevent the upgrading one version of a library from having unintended effects across different projects.
I would love to see NI package manager \ LabVIEW support a per project "virtual environment". I could see this being accomplished by creating a per project user.lib and instr.lib. But that's just one idea...
I highly recommend NI examine, in detail, G Package manager and incorporate its per project capabilities into LabVIEW and NI Package manager. The ability to install multiple versions of the same package on a per project basis solves quite a few problems. That having been said we would also need the ability to install one package globally and resolve conflicts between the per project and global versions of a library.
FYI: please be aware of the labviewwiki.org article comparing the three different package managers:
