# datasette 1.0a33 > Source: > Published: 2026-06-11 15:26:49+00:00 **Release:** [datasette 1.0a33](https://github.com/simonw/datasette/releases/tag/1.0a33) This alpha is a significant step on the road to a stable 1.0, finally extending the `?_extra=` pattern I introduced [in Datasette 1.0a3](https://docs.datasette.io/en/1.0a3/changelog.html#a3-2023-08-09) to cover queries and rows in addition to tables. That pattern is also [now documented](https://docs.datasette.io/en/latest/json_api.html#expanding-json-responses)! I wrote a whole lot more about the new release on the Datasette project blog: ** Datasette 1.0a33 with JSON extras in the API**. Because API explorer tools are almost free to build now I had Claude Fable 5 in Claude Code (for [the plan](https://gist.github.com/simonw/d8bf1a8f36e28fbd595cede946e0ab6d)) and GPT-5.5 xhigh in Codex Desktop (for [the implementation](https://gist.github.com/simonw/12d5e09797072a6807d7b9cfcc8ff6b7)) build me this [custom extras API explorer](https://tools.simonwillison.net/datasette-extras-explorer) to help demonstrate the feature: Tags: [projects](https://simonwillison.net/tags/projects), [datasette](https://simonwillison.net/tags/datasette), [annotated-release-notes](https://simonwillison.net/tags/annotated-release-notes), [ai-assisted-programming](https://simonwillison.net/tags/ai-assisted-programming)
