Maintainer checklist

• The commit messages for the remote branch should be checked to make sure the contributor's email is set up correctly so that they receive credit for their contribution

  • The contributor's name and icon in remote commits should be the same as what appears in the PR
  • If there's a mismatch, the contributor needs to make sure that the email they use for GitHub matches what they have for git config user.email in their local Scribe-iOS repo

• The CHANGELOG has been updated with a description of the changes for the upcoming release and the corresponding issue (if necessary)
