+- ([#12114](https://github.com/quarto-dev/quarto-cli/issues/12114)): `JUPYTERCACHE` environment variable from [Jupyter cache CLI](https://jupyter-cache.readthedocs.io/en/latest/using/cli.html) is now respected by Quarto when `cache: true` is used. This environment variable allows to change the path of the cache directory.

 ## Other Fixes and Improvements
 
 - ([#7260](https://github.com/quarto-dev/quarto-cli/issues/7260)): Add support for `active` class in tabsets so the `.active` tab shows up by default.
