Looks all good to me! Just version changes.

Here are the steps we took to release v0.1.48:

• Ask Michael if he would have time to deal with updating the documentation for the new release
• Create a PR that bumps all the versions before you cut a new release.
• Draft a new release, "Create a new tag", title v0.1.49, "Generate Release Notes"
• Click "Publish" (it's not a draft)
• Don't worry about the "signing" pipeline job failing. It hasn't be working for a while.
• "Run Workflow", Fill in "The tag to release" with v0.1.49
• Once the Helm chart is pushed to GCR and image pushed to Quay.io, David Barranco has a cron job that syncs the GCR registry to Harbor. Wait until the new image and Helm chart appears in Harbor.
