+## Engines
+
+### `julia`
+
+- Update `julia` engine extension from 0.1.0 to 0.2.0 and QuartoNotebookRunner from 0.17.4 to 0.18.1.
+- Add `keep-ipynb` support. When `keep-ipynb: true` is set in document YAML, the executed notebook is written alongside the source file.
+- Add shared worker processes. Multiple notebooks sharing the same config can reuse a single worker process via `julia: share_worker_process: true`.
+- Add support for `execute-dir: project` to set working directory to project root.
+- Add diagnostic file logging via `QUARTONOTEBOOKRUNNER_LOG` environment variable.
+- Cache worker package environments across sessions, skipping environment setup on subsequent runs when Julia and QNR versions haven't changed.
+- Relax manifest version checking to major.minor by default, matching Julia's Pkg behavior. Opt into strict checking via `julia: strict_manifest_versions: true`.
+- Fix `fig-format: retina` by normalizing to `png` with doubled `fig-dpi`, matching Jupyter and knitr backends.
+- Fix cache invalidation to hash full `Manifest.toml` content so dependency version changes correctly invalidate the cache.
+- Fix duplicate YAML keys when Python/R cells have cell options like `echo`.
