TLS configuration unavailable in helm chart values

[r0bj]

What happened:
According to the changelog, custom TLS configuration was added in Helm chart version 3.8.3. I can see the TLS configuration in the values.yaml file on the master branch here. However, it’s unavailable in the latest Helm chart I downloaded, which is version 3.12.2:

$ helm repo add metrics-server https://kubernetes-sigs.github.io/metrics-server/
$ helm repo update
$ helm show values metrics-server/metrics-server --version 3.12.2 | grep -i 'tls:'
<empty>

What you expected to happen:
The custom TLS configuration should be available in the latest Helm chart. As far as I know, it should have been available since version 3.8.3.

@r0bj the Helm chart is released from the release branches. If you look at the CHANGELOG on master you'll see the TLS config is unreleased.

When is the chart going to be released? The MR was merged over half a year ago.

@steinwelberg the chart release process is documented. The primary driver is still an issue being opened and triaged, although it's actually more complicated now as the release has to come off a release branch. This is exactly the same as for how code merged to master gets released.
