+## Extensions
+
+- Metadata and brand extensions now work without a `_quarto.yml` project. (Engine extensions do too.) A temporary default project is created in memory.
+
+- New **Engine Extensions**, to allow other execution engines than knitr, jupyter, julia. Julia is now a bundled extension. See [the prerelease notes](https://prerelease.quarto.org/docs/prerelease/1.9/) and [engine extension documentation](https://prerelease.quarto.org/docs/extensions/engine.html).
