@ThomasK33 thanks for your patience. Could you add a chart CHANGELOG entry under a new ## [UNRELEASED] heading at the top and following the conventions from the last entry?

[stevehipwell]

@ThomasK33 I'd like to get this in the next release, would you be able to add a CHANGELOG entry and squash back to a single commit?

@ThomasK33 ignore the bit about the next release as I can see that this is waiting on #3055 but it'd still be good to have a CHANGELOG entry for the chart in the PR.

Sure, I'll update it today, but there is no point in having this in the next release, as #3055 still isn't merged.

Hey @stevehipwell 👋

As #3055 was merged last week, I've updated this PR to include the additional, new apiGroup for Traefik traefik.io.

Let me know if anything else needs to be added. 😄
