 - [ ] Open a PR against `master` cherry-picking the CHANGELOG commits from the `release/v{{.Tag}}` branch. Title it `chore(release): cherry-pick v{{.Tag}} changelog back to master`
    - Link to PR:
    - Assuming we followed [the process of merging changes into `master` first before backporting to the release branch](https://github.com/filecoin-project/lotus/blob/master/LOTUS_RELEASE_FLOW.md#branch-and-tag-strategy), the only changes should be CHANGELOG updates.
 - [ ] Finish updating/merging the [RELEASE_ISSUE_TEMPLATE.md](https://github.com/filecoin-project/lotus/blob/master/documentation/misc/RELEASE_ISSUE_TEMPLATE.md) PR from `Before RC1` with any improvements determined from this latest release iteration.
