@YVbakker we can't move across major version dependencies in a minor release as this would break customer running in the managed host after an update.

The dependencies brought in by this package are primarily used at development time. Those dependencies are serviced as part of the host, and at runtime, what you bind against are those versions (so you'll be running against patched versions that match the runtime environment).

I'm closing this for now but will share some of the details in the associated issue. We'll also follow up with updates within proper ranges to address build/compliance noise.
