  Structured capture of the Amazon S3 API "Document History / What's New" feed.
  S3 keeps the wire API version pinned at 2006-03-01 and evolves additively, so
  changelog entries are dated feature/documentation additions rather than API
  version bumps. The live What's New page is the source of truth; this records the
  recent window. AWS also publishes broader S3 announcements on the AWS What's New
  and Storage blog feeds.
