Upgrade hier_config version from 2.x.x to 3.x.x

[matthew-ursys]

Is it possible to please upgrade the dependency library for this - it would make conflict resolution much nicer for us

[patrickfnielsen]

I would also like to see this - If it helps I can help with a PR

Please elaborate on your use-cases, how hier_config 2.3 is problematic and why you absolutely cannot live with hier_config 2.3.

As an FYI, version 2.3 is marked long-term support if you read the git branch name.

A lot of distributions like Nixpkgs are at hier_config > 3. At the moment the pinning of hier_config to 2.3.1 is problematic like all pinning of modules as soon as the usage is longer limited to a venv.

Support for hier_config > 3 would be appreciated.

Thanks

that's an interesting data point, but not yet compelling to change. Virtualenvs were made for exactly this problem.
