Release notes, 23 October 2026

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 says the label names the format of what is sent, and an agent asking for Markdown gets a whole web page instead.
