+### Chore
+
+- Moved `docs` and `tests` extras, as well as `dev-dependencies`,
+  inside groups in `dependency-groups`. This could break existing code
+  when using one of those extras, but as they were not part of the public API,
+  we do not consider this to be a **breaking change**.

+
+- HTML template now always includes the *notes* plugin so that the speaker
+  view is always available. Previously, it was only included if the slides
+  had notes.
+  [#538](https://github.com/jeertmans/manim-slides/pull/538)
+- Pressing <kbd>SPACE</kbd> key now pauses the slides, instead of skipping it.
