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.
