What

Weekly changelog for 2026-09-28 and its launch thread.

  • Entry: apps/marketing/content/changelog/2026-09-28-file-editing-instant-workspaces.mdx
  • Launch thread: apps/marketing/content/changelog/2026-09-28-tweet.md (not rendered by the site)
  • New images: 2026-09-28-save-conflict-hero.png, 2026-09-28-file-changed-banner.png, 2026-09-28-mobile-settings.png. The iPhone hero is reused from /images/blog/superset-mobile/.

Sections

  • Safer File Editing (#7711, #7693, #7692): changed-on-disk banner, save conflict dialog, auto save, file tree drag and rename. Credits @theblondealex.
  • Workspaces Start Instantly (#7518)
  • GPT-6 and Claude Opus 5.5 (#7741, #7783, #7894). Credits @haydenfd.
  • Superset for iPhone Is on the App Store (#7686, #7697, #7661, #7816, #7782)
  • 7 improvements and 14 bug fixes

Left out on purpose: cloud environments (#7838 to #7874, still gated), the security PRs reverted by #7834, the #7870/#7871 revert pair, and the canary-only #7873.

How I checked it

  • Screenshots come from the dev desktop on a throwaway demo repo. The absolute path in the dialog was replaced before capture.
  • bun run lint exits 0. bun run --cwd apps/marketing lint:prose reports 0 errors and 0 warnings.
  • The entry renders at localhost:3242/changelog/2026-09-28-file-editing-instant-workspaces with all images.

Typefully drafts X 10972409 and LinkedIn 10972410 are planned, not published.
