Design updates to repositories and GitHub UI

Today we’ve launched a refresh to the design of GitHub UI, and layout changes to your repository homepage. We hope these changes improve your experience visiting and maintaining repositories, and using GitHub in general. Along with visual design changes, you’ll see the the following updates to your repository homepage:

• Responsive layout and improved mobile web experience
• More content surfaced via the repository sidebar
• Ability to show or hide Releases, Packages, and Environments in your repository sidebar

These changes lay the foundation for future incremental improvements that will better surface your projects, the people who make them extraordinary, accessibility, and yes, dark mode.
