-Move from react to raw remark.
+The release is a complete rewrite of the underlying process to generate the
+HTML files. React was removed from the project and replaced with remark
+plugins. This improves build times and give us more control over the whole
+process. For example there is no need anymore for running `npx hyperbook
+setup`.
+
+I also added a new pagelist directive, which can be used to list pages based
+on user-defined criteria. This directive also replaces the included glossary
+page. Therefore, you need to create on yourself. This can be easily done by
+creating a page `glossary.md` with the following content:
+
+```md
+---
+name: Glossary
+---
+
+::pagelist{format="glossary" source="href(/glossary/)"}
+
+```
+
+Additionally, I added the ability to use custom JavaScript and CSS-files - see
+the documentation under Advanced Features - in addition to using HTML in your
+hyperbook, when the `allowDangerousHtml` option is enabled in your config.
+
+I also improved the appearance of custom links, by moving them to the
+footer on mobile devices.
