@@ -127,5 +127,6 @@ All changes included in 1.5:
 - Add support for `{{< lipsum >}}` shortcode, which is useful for emitting placeholder text. Provide a specific number of paragraphs (`{{< lipsum 3 >}}`).
 - Resolve data URIs in Pandoc's mediabag when rendering documents.
 - 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).
+- When running `quarto check` from a development build (from a git repository), show the git commit hash in addition to the version string.
 - Upgrade Deno to 1.41.0
 - `quarto install tinytex` will now try to set the default CTAN repository to the nearest mirror resolved from https://mirror.ctan.org.
