Relocated content from docs/topics/external-packages.txt where appropriate.

Following up a forum post and a conversation with the Steering Council, it was decided to remove the docs/topics/external-packages.txt to avoid confusion with the Ecosystem page. Relevant content was moved to their related sections, except for `django-contrib-comments` which is not actively maintained. Thank you Tim Schilling for the review.

Fixed #36806 -- Added system check for null kwarg in GeneratedField.

2025-12-22T14:41:41Z

The null argument has no effect on GeneratedField since the nullability of the column depends on the database and expression used.

Fixed #36765 -- Added support for stored GeneratedFields on Oracle 23ai/26ai (23.7+).
