Maintainer Checklist

The following is a checklist for maintainers to make sure this process goes as well as possible. Feel free to address the points below yourself in further commits if you realize that actions are needed :)

• The linting, formatting and testing workflows within the PR checks do not indicate new errors in the files changed

  • Tests may need to be reran as they're at times not deterministic

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

First PR Commit Check

• 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-Android repo (can be set with git config --global user.email "GITHUB_EMAIL")
