ChangeLog

The complete history is kept in CHANGELOG.md.

0.5.1 - 2026-11-11

Fixed

The CLI export included the page types excluded with llmsTxtExcludeDoktypes; their subpages now take their place
llmsTxtExcludeDoktypes written as a number into the site YAML ended llms.txt with an error

Security

The CLI export followed redirects, so the address of an "External URL" page or a redirect record was requested from the server. Redirects are no longer followed; such pages are skipped

Important

The .md links in llms.txt and the link to llms.txt in the page head are built by the router. Without the route enhancer they now use ?type=1701 and ?type=1699, which work, instead of URLs that did not resolve.
ai-llms:download-markdown exports the whole page tree, names files after the page's URL segment by default, and ends with a non-zero exit code when a page fails. Check scripts that process its output.
Tables become Markdown tables in the Markdown version, and llms.txt no longer escapes periods, hyphens or parentheses.
league/html-to-markdown 5.2.3 or later is required.

Added

Fixed

.md links in llms.txt for sites whose page URLs end in .html or that do not import the route enhancer
Missing spaces between inline elements, and code blocks collapsed onto one line, in the Markdown version
Paragraphs such as "SPSS" were dropped from the Markdown version
The description of top-level pages was missing in llms.txt
Subpages of an excluded page type below the first level were listed out of order
The CLI export only exported the first level of pages; --format=slug, --dry-run, unknown sites and the exit code did not work as documented
The link to llms.txt in the page head ignored the site's base path and was also added for disabled sites
A warning for untranslated pages of a fallback language in the language-aware page queries
The content elements of a b13/container grid appeared twice in the Markdown version
Content that is not cacheable, such as USER_INT objects or plugins with filters, was missing from the Markdown version. It is now rendered, and a page with such content is no longer kept in TYPO3's page cache

Security

league/html-to-markdown 5.2.3 is required, which fixes code, links and attributes breaking out of their Markdown, and quadratic conversion time

Important

The Markdown version of a page is served as Content-Type: text/markdown instead of text/plain. Check proxies, CDN rules or clients that match on the content type.
If the content of a page starts with an <h1>, the Markdown version no longer adds the page title as a second main heading.

Added

Support for PHP 8.5 (#17)
README sections on security updates, uninstallation, automatic updates, notes for integrators and the SBOM (#16)

Fixed

Second main heading in the Markdown version when the content starts with an <h1>
Top-level pages in llms.txt were listed with + instead of -
Content following an <aside> or <footer> containing a <div> was lost in the Markdown version

Important

TYPO3 12 is no longer supported. The extension requires TYPO3 13.4 LTS or 14.3 LTS.
The Markdown version of a page now answers with "page not found" when the extension is disabled for the site, or when the page has Index this page switched off.

Added

Site setting llmsTxtExcludeDoktypes to leave additional page types out of llms.txt (#1)
Optional caching with llmsTxtCacheLifetime, disabled by default (#2)
Support for TYPO3 14.3 LTS
Logging of generation errors, X-Content-Type-Options: nosniff header
Documentation of all settings, the CLI export and known limitations

Fixed

Pages of other languages appeared in the language sections of llms.txt (#10)
Translated SEO title and description, and text after text & media elements, in the Markdown version (#7)
Wrong .md links for page URLs ending with a slash (#8)
Excluded page types, translated subpages and language fallback handling in llms.txt
Performance on large page trees: queries are batched per tree level
llms.txt stayed in TYPO3's page cache for up to a day; it now follows llmsTxtCacheLifetime, and error responses are not cached

Security

The Markdown version ignored the site's enable switch and the page's "no index" flag
Error messages in the Markdown output could expose internal details
Escaped markup in page content became live HTML in the Markdown output
Line breaks and Markdown syntax in titles, descriptions and settings could inject lines into llms.txt and keys into the CLI export's YAML frontmatter

Refactored ConfigurationService to receive the request once via setRequest()
Unit tests for ConfigurationService
TYPO3 14 support in the test runner

Fixed the exclusion of folders, separators and shortcuts so that their subpages are still listed

Folders, separators and shortcuts are excluded from llms.txt, their subpages are listed instead

llms.txt generation according to the llmstxt.org specification, with the site's page tree up to a configurable depth
Markdown version of every page via the .md suffix
Route enhancers for /llms.txt, /.well-known/llms.txt and .md
