 Check that a link to the release notes for the new version is present in the navigation menu (defined in `mkdocs.yml`), and that a summary of all major new features has been added to `docs/index.md`.
 
+### Adopt the Dependency Requirements Matrix
+
+For every minor release, update the dependency requirements matrix in `docs/installation/upgrading.md` ("All versions") to reflect the supported versions of Python, PostgreSQL, and Redis:
+
+1. Add a new row with the supported dependency versions.
+2. Include a documentation link using the release tag format: `https://github.com/netbox-community/netbox/blob/v4.2.0/docs/installation/index.md`
+3. Bold any version changes for clarity.

+### Update System Requirements
+
+If a new Django release is adopted or other major dependencies (Python, PostgreSQL, Redis) change:
+
+* Update the installation guide (`docs/installation/index.md`) with the new minimum versions.
+* Update the upgrade guide (`docs/installation/upgrading.md`) for the current version accordingly.
