+## 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`.

+# Quarto Julia Engine changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## Unreleased
+
+## [0.2.0](https://github.com/PumasAI/quarto-julia-engine/releases/tag/v0.2.0) - 2026-03-24
+
+- Added `keep-ipynb` support. When `keep-ipynb: true` is set in document YAML, the executed notebook is written to `<stem>.ipynb` alongside the source file [#8](https://github.com/PumasAI/quarto-julia-engine/pull/8).
+- Updated to QuartoNotebookRunner 0.18.1 [#11](https://github.com/PumasAI/quarto-julia-engine/pull/11):
+  - **`fig-format: retina` support**: Normalized to `png` with doubled `fig-dpi`, matching Quarto's Jupyter and knitr backends. Fixes blurry plots with default HTML settings.
+  - **Improved cache invalidation**: Cache key now hashes full `Manifest.toml` content (SHA-224) so dependency version changes correctly invalidate the cache.
+- Updated to QuartoNotebookRunner 0.18.0 [#7](https://github.com/PumasAI/quarto-julia-engine/pull/7):
+  - **Shared worker processes**: Multiple notebooks can share a single worker process when their configs match. Enable with `share_worker_process: true`.
+  - **`execute-dir` support**: Quarto's `execute-dir` option (e.g. `execute-dir: project`) is now passed through correctly.
+  - **Cached worker environments**: Worker envs persist across sessions, skipping environment setup on subsequent runs when Julia and QNR versions haven't changed.
+  - **Relaxed manifest version checking**: Only major.minor is checked by default, matching Julia's Pkg behavior. Opt into strict major.minor.patch via `julia: strict_manifest_versions: true`.
+  - **Diagnostic file logging**: Set `QUARTONOTEBOOKRUNNER_LOG` to a directory path to enable timestamped log files.
+  - **Echo handling for Python/R cells**: Fixed duplicate YAML keys and added proper support for `echo: false` and `echo: fenced`.
+
+## [0.1.0](https://github.com/PumasAI/quarto-julia-engine/releases/tag/v0.1.0) - 2026-03-19
+
+- Initial release as a standalone Quarto extension, extracted from [quarto-cli](https://github.com/quarto-dev/quarto-cli).
+- Bundled Julia resource files (`Project.toml`, `ensure_environment.jl`, `quartonotebookrunner.jl`, `start_quartonotebookrunner_detached.jl`) into the extension, making it fully self-contained [#6](https://github.com/PumasAI/quarto-julia-engine/pull/6).
+- Added CI workflow with tests on Linux, macOS, and Windows [#6](https://github.com/PumasAI/quarto-julia-engine/pull/6).
