Zensical Monthly 04/2026
AI agents don't stop when your docs have a gap. They guess – confidently, fluently, and wrongly. This month's Zensical Monthly is about what that means for technical writers, and what we're building about it.
Web version:

Today, we're launching Zensical Studio, the missing productivity layer for Docs-as-Code. The idea is simple: Refactor documentation like code. Rename headings safely. Catch [broken links] instantly.
Works with Zensical and MkDocs projects. zensical.org/studio/
Zensical 0.0.38 is out! 🎉 Link and footnote validation + strict mode are here – now catches broken links, unresolved references, and shadowed definitions at build time.
You'll probably catch and fix a few issues when upgrading. We did too! 🫣

Zensical 0.0.35 just arrived. What we shipped:
- 🌄 Image zoom + galleries with GLightbox
– 🏗️ Rich formatting in the table of contents
– 🔗 Resolution of relative links in raw HTML
Release notes:

Zensical 0.0.44 brings further improvements to link validation. You might have noticed we've been quieter than usual – we've been heads down on a major milestone for Zensical. We'll share everything in Zensical Monthly, our newsletter, on June 10!

Zensical 0.0.37 adds support for installable themes – you can now package your existing customizations into a theme that can be installed via pip exactly as with MkDocs.

Zensical 0.0.39 is out – a bugfix release smoothing out edges on link validation and the new lightbox integration.
github.com/zensical/zen...
Zensical 0.0.40 is out with macro support. You can now use macros inside Markdown files and even docstrings – a much-requested feature that was never possible with mkdocs-macros.
Release notes:
github.com/zensical/zen...
Zensical 0.0.42 improves stability and accuracy of link validation, and fixes some bugs related to file watching, abbreviations in the table of contents, and GLightbox.
