note: >-
  The only dated, structured changelog OptinMonster publishes is the WordPress plugin's
  CHANGELOG.md in the WordPress.org SVN trunk (mirrored into the plugin's readme.txt). There is NO
  changelog for the platform or for the REST API — optinmonster.com/changelog/ returns 404, and API
  version changes (v1 vs v2 resource moves, host migrations) are not announced anywhere. Two
  entries below are notable as the closest thing to an API changelog that exists: 2.16.16 records
  "Updated URL used for OptinMonster API calls" — the undocumented migration of the plugin's API
  base to api.omwpapi.com — and 2.16.23 is published as "Unreleased", a version number burned in
  public with no content. Product announcements otherwise appear as marketing blog posts.
