 - ([#6833](https://github.com/quarto-dev/quarto-cli/issues/6833)): Handle partially-specified aspect ratio, width, and height attributes in `video` shortcode.
 - ([#7137](https://github.com/quarto-dev/quarto-cli/discussions/7137)): Automatically set `rel="noopener"` when setting a target on external links
+- ([#7187](https://github.com/quarto-dev/quarto-cli/issues/7187)): Add `html-table-processing: none` to document- and project-level metadata to disable HTML table processing. Add `{html-table-processing="none"}` to a fenced div to disable HTML table processing for the elements in that div.
