 ## 0.22.18
 
+### Fixes
+- Make `ingest-test-fixtures-update-pr` CI job also update the markdown versions of the fixtures.
+
 ### Enhancements
 - **Add page number support to v1 HTML parser**: The v1 HTML parser now reads `data-page-number` attributes from ancestor elements and includes the page number in element metadata, consistent with the v2 parser behavior.
