# Release notes, 23 October 2026

A web page sent where Markdown was asked for is now caught when a script comes before its doctype.

## Summary

One check now catches more sites. If you serve Markdown to agents and your results were clean, scan again: a page that starts with a script may be sending its web page instead of Markdown.

A page that really serves Markdown is not affected, including one that starts with a script and then carries on in Markdown.

## Fixed

-   Markdown for agents: a web page labelled `text/markdown` is now reported when a script comes before its doctype line, as it does on pages with a tracking pixel. We only looked past comments before, so these pages passed. [RFC 9110](https://www.rfc-editor.org/rfc/rfc9110.html#section-8.3) says the label names the format of what is sent, and an agent asking for Markdown gets a whole web page instead.
