Hi Rod,
There was a bug around this in the past where only the latest helm chart was listed in index.yaml on the `gh-pages` branch, leading to only the latest version being available to helm. This has been fixed.
The timestamps for older charts will change when a new version is released because we are generating index.yaml every time. But functionally there is no difference, older version of the awx-operator helm chart will still be available.
There is some context on this PR and the linked PR's:
Thanks,
AWX Team
