Commenting, mentions, and closing issues from commits

Discuss issues with markdown comments, @mentions, and commit keywords.

1. Add a comment
On /{owner}/{repo}/issues/{number}, scroll to Add a comment, write markdown in the textarea, preview if needed, and click Post comment.
2. Mention teammates
Type @username in a comment to notify that user. They will see it under Notifications.
3. Link commits to issues
Include #123 in a commit message to reference issue 123. Use fixes #123 or closes #123 (case-insensitive) to auto-close an open issue when the commit lands on the default branch only.
4. Commit comments
On a commit detail page you can also start commit comment threads and discuss specific diffs.
