Notes and changelog
What changed in Google’s documented requirements, what changed in this tool, and the dates attached to both.
Recorded feature changes
| Effective | Feature | Status | What it means |
|---|---|---|---|
| 2026-05-07 | FAQ | REMOVED | Valid schema.org. No longer produces a Google FAQ rich result as of 7 May 2026. Still parsed by other search engines and by AI crawlers. Keeping the markup is harmless; expecting a Google feature from it is not supported. |
The full registry, including entries with no dated change, is on the coverage page.
Writing in progress
