@@ -31,6 +31,7 @@ All changes included in 1.9:
 - ([#13474](https://github.com/quarto-dev/quarto-cli/issues/13474)): Heading font for title should default to `mainfont`.
 - ([#13555](https://github.com/quarto-dev/quarto-cli/issues/13555)): Add support for `icon=false` in callouts when used in `format: typst`.
 - ([#13589](https://github.com/quarto-dev/quarto-cli/issues/13589)): Fix callouts with invalid ID prefixes crashing with "attempt to index a nil value". Callouts with unknown reference types now render as non-crossreferenceable callouts with a warning, ignoring the invalid ID.
+- ([#13602](https://github.com/quarto-dev/quarto-cli/issues/13602)): Fix support for multiple files set in `bibliography` field in `biblio.typ` template partial.
