+- ([#8873](https://github.com/quarto-dev/quarto-cli/issues/8873)): Don't overwrite supporting files when creating a project.
 - Add support for `{{< lipsum >}}` shortcode, which is useful for emitting placeholder text. Specify a specific number of paragraphs (`{{< lipsum 3 >}}`).
 - Increase v8's max heap size by default, to avoid out-of-memory errors when rendering large documents (also cf. https://github.com/denoland/deno/issues/18935).
