+You now have a tag and release using the semver version you used above. The last remaining thing to do is to update the major version branch to match the current release. This allows users to adopt a major version number (e.g. `v4`) in their workflows while automatically getting all the minor/patch updates.
 
-To do this just checkout `main`, force-create a new annotated tag, and push it:
+As of v4.8.3, we use a **branch** (not a force-pushed tag) for the major version pointer. This is important because force-pushing tags breaks GitHub's auto-generated release changelog links (see [#1035](https://github.com/actions/dependency-review-action/issues/1035)) and violates git's (unenforced) expectation that tags are immutable.
+
+To update the major version branch:
 
 ```
-git tag -fa v4 -m "Updating v4 to 4.0.1"
-git push origin v4 --force
+git checkout main
+git pull origin main
+git branch -f v4 HEAD
+git push origin v4
 ```
