@aaronayres35 fixes is one of the special words that github uses to automatically link Issues with Pull Requests (PRs). See full list of special words here - https://docs.github.com/en/github/managing-your-work-on-github/linking-a-pull-request-to-an-issue#linking-a-pull-request-to-an-issue-using-a-keyword . Using that special word with the issue number, in this case #567 , means that when this PR gets merged, the issue will automatically get closed.

Once you merge the PR, you will also need to manually delete the branch.

I've changed the settings on this repository so that branches are automatically deleted at merge time.
