  Adobe has no single estate-wide changelog. It publishes a dated per-product changelog
  for a handful of surfaces and communicates the rest through the Adobe Developers blog
  and Experience League release notes. The Adobe Express Add-on changelog is the only one
  with a genuine dated entry stream, so it carries this artifact; the others are recorded
  as pointers with their scheme.

  highlights:
  - >-
    Dark theme support: the `theme` property and `themechange` event now report both
    "light" and "dark". Add-ons submitted to the marketplace after 2026-08-31 are
    REJECTED if their UI is functionally broken in dark mode.
  - >-
    Large Document Support reached Phase 2 — new APIs stable, deprecated ones removed,
    migration window open.
  - >-
    Stabilized (no longer behind the experimentalApis flag): visitPages(),
    keepContentActiveDuringAsync(), addOnUISdk.app.document.isPresentation(),
    editor.createThreadedText(), ThreadedTextContentModel.allFrames,
    ThreadedTextList.addFrame().
  removals:
  - queueAsyncEdit
  - PageNode.artboards
  - PageNode.allDescendants
  - PageNode.allTextContent
  - PageNode.cloneInPlace
  removal_note: 'Adobe, verbatim: "removed from the SDK—local builds that still reference them will fail."'
  additions:
