-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 pull origin main
+git branch -f v4 HEAD

+#### `OTHER` in license strings
+
+License data comes from [ClearlyDefined](https://clearlydefined.io) and you may sometimes see licenses displayed with the string `OTHER` in them. ClearlyDefined [defines OTHER](https://docs.clearlydefined.io/docs/curation/curation-guidelines) as:
+
+> This indicates that a human confirmed that there is license information in the file but that the license is not an SPDX-identified license.
+
+`OTHER` is not a valid [SPDX license identifier](https://spdx.org/licenses/), so we convert `OTHER` in a license string into `LicenseRef-clearlydefined-OTHER`, which _is_ valid in SPDX. If you want to add that to the deny or allow list, be sure to add `LicenseRef-clearlydefined-OTHER` to this list, because that is what we'll actually be comparing.
