According to our Quarterly Release Policy:

• Changes go through dev first for testing before being merged to master during quarterly release windows (1st & 3rd Fridays)
• PRs to master are only allowed for emergencies

Required Action:

1. Change the base branch from master to dev
2. Follow the pull request template

If this is an emergency fix, please add a comment explaining why it needs to target master directly.
