* Add the ability to apply basic Page QuerySet optimizations to `specific()` sub-queries using `select_related`&`prefetch_related`, see [](../reference/pages/queryset_reference.md) (Andy Babic)
* Move the [model reference page](../reference/models.md) from reference/pages to the references section as it covers all Wagtail core models (Srishti Jaiswal)
* Move the [panels reference page](../reference/panels.md) from references/pages to the references section as panels are available for any model editing, merge panels API into this page (Srishti Jaiswal)
* Move the tags documentation to standalone [advanced topic for tagging](../advanced_topics/tags.md), instead of being inside the reference/pages section (Srishti Jaiswal)
* Refine the [](adding_reports) page so that common (page/non-page) class references are at the top and the full page only example has correct heading nesting (Alessandro Chitarrini)
* Recommend a larger `DATA_UPLOAD_MAX_NUMBER_FIELDS` when [integrating Wagtail into Django](../getting_started/integrating_into_django.md) (Matt Westcott)
* Update all JavaScript inline scripts & some CSS inline style tags to a CSP compliant approach by using external scripts/styles (Aayushman Singh)
* Update usage of `mark_safe` to `format_html` for any script inclusions, to better avoid XSS issues from example code (Aayushman Singh)
* Update documentation writing guidelines to [encourage better considerations](documentation_code_example_considerations) of security, accessibility and good practice when writing code examples (Aayushman Singh, LB (Ben) Johnston)
It's recommended that all projects set the `DATA_UPLOAD_MAX_NUMBER_FIELDS` setting to 10000 or higher.
This specifies the maximum number of fields allowed in a form submission, and it is recommended to increase this from Django's default of 1000, as particularly complex page models can exceed this limit within Wagtail's page editor:
