Chart: Changelogs not contained in GitHub releases.

[lexfrei]

Looks like, the chart should generate and post chengelog somewhere.

Currently, there are no changelogs posted in releases for chart.

We really need to know about breaking changes, like https://github.com/kubernetes/ingress-nginx/pull/10393

Also, this breaking change is not mentioned in chart's changelog and it's a problem. As chart user, I can't expect so big change without a line in changelog.

/remove-kind bug Do you mean this needs to change https://github.com/kubernetes/ingress-nginx/blob/main/charts/ingress-nginx/changelog/Changelog-4.8.3.md

We could add a link to the controller release notes in the helm release notes,

The controller and helm charts have a separate release cadence.

We always update the support table that maps controller to chart https://github.com/kubernetes/ingress-nginx#supported-versions-table

Let me explain.

1. There are no changelogs on release pages. Yes, it's possible to find, but it's not easy. We are expecting them on a release page.
2. It's not fine to change behaviour without mentioning it. The chart is a separate product and it's not clear how it handles changes in the controller. I can't expect such a big change of behaviour in a minor version without a BIG RED ALERT MESSAGE.

I guess all @lexfrei wants is something adding the content of the generated changelog file to be included in the Helm chart releases.

This mage step generates the changelog: https://github.com/kubernetes/ingress-nginx/blob/main/magefiles/steps/release.go This action generates the helm-chart-* releases: https://github.com/kubernetes/ingress-nginx/blob/main/.github/workflows/helm.yaml

btw: I also have a PR open for improving the way those changelogs are getting named & templated: https://github.com/kubernetes/ingress-nginx/pull/10622

I could try to improve the action so it also contains the changelog's content.
