 Over the last ten months, the Jupyter Book team have been hard at work; Jupyter Book has [become a Jupyter subproject](https://github.com/jupyter/governance/pull/229), and the team[^jb-eb] announced a [plan to release Jupyter Book 2][plan]. This post announces the **alpha release of Jupyter Book 2.0**, which has been re-written from the ground up to use the new MyST-MD engine.

 ### High Quality PDFs
 
 PDF documents can now be built with Typst, a high-quality typesetting engine that produces readable error messages and beautiful documents. This feature was the basis for the 2024 [SciPy proceedings][proceedings], which is now built on MyST Markdown and will be accepting Jupyter Notebooks in 2025.
