+### Headless documentation
+
+The new [](headless) documentation page curates important information about Wagtail’s headless capabilities, directly within the developer documentation. This is the foundation for a [headless improvements roadmap](https://github.com/wagtail/rfcs/pull/100) for Wagtail.
+
+Thank you to Sævar Öfjörð Magnússon and Alex Fulcher for creating this new page at the Wagtail Space NL 2024 sprint.

+### Alt text improvements
+
+Building upon improvements in past versions, this releases comes with further enhancements to alt text management:
+
+ * The [content modeling accessibility considerations](content_modeling) now reflect the latest capabilities for alt text.
+ * The new ImageBlock alt text is now populated from the image’s default alt text when selecting a new image.
+ * The ImageBlock alt text field is also populated from the image’s default alt text when converting from an ImageChooserBlock.
+ * Alt text quality is now checked by default as was intended with the `alt-text-quality` content check.
+
+Thank you to Matt Westcott, Thibaud Colas, and Cynthia Kiser for their work on these improvements.
