The Project file not really, that’s quite important. It depends on what you’re using it for specifically (that’s why I asked), but only for testing regular packages I’d recommend not checking in the Manifest and let the package manager resolve the environment. Manifests are very version-dependent, so when you upgrade Julia to a newer minor versions they aren’t useful anymore (hence the warning). Manifests are useful for reproduction of an application/pipeline which is running with a fixed version of Julia.
