 ## In this release
 
+- ([#14304](https://github.com/quarto-dev/quarto-cli/issues/14304)): Fix `quarto install tinytex` silently ignoring extraction failures.

 - ([#14267](https://github.com/quarto-dev/quarto-cli/issues/14267)): Fix Windows paths with accented characters (e.g., `C:\Users\Sébastien\`) breaking dart-sass compilation.
