 If you know that some labels have changed in Github, you will want to refresh the data.

+## Full PR list
+
+At times, it may be useful to get a raw full PR list.
+In order to produce this list, you first need to fetch the the latest `context.json` from the `release-notes-context` artifacts you can find [here](https://github.com/paritytech/polkadot/actions/workflows/release-30_publish-draft-release.yml). You may store this `context.json` under `scripts/ci/changelog`.
+
+Using the `full_pr_list.md.tera` template, you can generate the `raw` list of changes:
+
+```
+cd scripts/ci/changelog
+tera --env --env-key env  --template templates/full_pr_list.md.tera context.json
+```
