## What's new

### Other features

 * Add clarity to confirmation when being asked to convert an external link to an internal one (Thijs Kramer)
 * Convert various pages in the documentation to Markdown (Daniel Kirkham)
 * Add `base_url_path` to `ModelAdmin` so that the default URL structure of app_label/model_name can be overridden (Vu Pham, Khanh Hoang)
 * Add `full_url` to the API output of `ImageRenditionField` (Paarth Agarwal)

### Bug fixes

 * Fix issue where `ModelAdmin` index listings with export list enabled would show buttons with an incorrect layout (Josh Woodcock)


## Upgrade considerations

### `base_url_path` keyword argument added to AdminURLHelper

The `wagtail.contrib.modeladmin.helpers.AdminURLHelper` class now accepts a `base_url_path` keyword argument on its constructor. Custom subclasses of this class should be updated to accept this keyword argument.
Housekeeping to start work on 4.0 (#8420) * Add release notes page for 4.0 * Version bump to 4.0 * Rotate deprecation warnings 2022-04-22 13:25:16 +00:00			`# Wagtail 4.0 release notes - IN DEVELOPMENT`
