What's new

Bug fixes

• Respect WAGTAIL_ALLOW_UNICODE_SLUGS setting when auto-generating slugs (LB (Ben) Johnston)
• Use correct URL when redirecting back to page search results after an AJAX search (Sage Abdullah)
• Provide convert_mariadb_uuids management command to assist with upgrading to Django 5.0+ on MariaDB (Matt Westcott)

Upgrade considerations

Changes to UUID fields on MariaDB when upgrading to Django 5.0

Django 5.0 introduces support for MariaDB's native UUID type on MariaDB 10.7 and above. This breaks backwards compatibility with CHAR-based UUIDs created on earlier versions of Django and MariaDB, and so upgrading a site to Django 5.0+ and MariaDB 10.7+ is liable to result in errors such as Data too long for column 'translation_key' at row 1 or Data too long for column 'uuid' at row 1 when creating or editing pages. To fix this, it is necessary to run the convert_mariadb_uuids management command (available as of Wagtail 5.2.5) after upgrading:

./manage.py convert_mariadb_uuids

This will convert all existing UUID fields used by Wagtail to the new format. New sites created under Django 5.0+ and MariaDB 10.7+ are unaffected.
