EVOLVING GITHUB ISSUES (PUBLIC PREVIEW)

Summary from the TLDR newsletter

GitHub has released sub-issues, issue types, and advanced search for issues to everyone. It has also updated the issues frontend to enable developers to work faster. Sub-issues allow developers to break down and organize issues within a parent-child hierarchy. Issue types let developers classify and manage issues with a shared and consistent language across all repositories in an organization. Advanced search enables complex filters so that developers can find the exact set of issues they are looking for.
