Hi @rddimon and @jcoaks, since this change has been approved, could you please merge this PR and release a new plugin version?

Hey @rddimon & @jcoaks any chance there is an updated release coming soon that will push out support for v4? I see the updates in main but the latest release is obviously from back in March. Thanks for help/work/tooling!
