Background

Implementation for elastic/integrations#5142. We want to surface integration changelogs to users when an update is available through the UI. Currently there is no context on expected changes:

Implementation Tasks

• Update the description in "New version available" callout to read: Upgrade to version {VERSION} to get the latest features. View changelog.
• View changelog. should open a modal that shows the changelog between the user's currently installed version and the version offered for upgrade. Please reference the UX for the current license and notice modal UI.
  • The changelog can be retrieved using getFile() from the registry service. The file to retrieve is (for example) located at https://epr.elastic.co/package/1password/1.8.0/changelog.yml
  • The changelog yaml will need to be parsed to return only the entries between the above two versions. The entries should be in descending version, starting with the version offered for upgrade

Next steps

After this work, the changelog is only accessible at time of upgrade. We need to figure out the UX for persistently offer the changelog.
