Instant previews, flexible editing, and working with issues in Copilot available in public preview

A dark-themed code editor interface displaying a preview of a 'Planetary Travel Time' calculator. The interface includes a rocket icon, a title, and a description prompting users to select a planet and a NASA spacecraft to calculate travel time from Earth. Dropdown menus show 'Mars' as the selected planet and 'Voyager 1' as the selected spacecraft. A floating 3D GitHub Copilot assistant with a glowing, futuristic helmet is visible in the bottom-right corner.

Inspired by our previous release, working with Copilot Chat on GitHub has become even more seamless. You can instantly preview HTML files, edit files you’ve created, and work on issues right away. Several exciting new capabilities give you more control and flexibility.

What’s new

  • Preview your rendered HTML files directly in the side panel
  • Edit files in the side panel to seamlessly refine and adjust them
  • Generate and preview Mermaid diagrams for fast visualizations, whether they’re flowcharts or sequence diagrams
  • Keep tabs on your issues in the same right side panel, ensuring you can tackle open tasks while discussing them
  • Track issues or pull requests in responses that are rendered in a familiar GitHub style, making working with them easier

In addition, you can enjoy a smoother streaming experience and enhanced rendering of attachments.

GitHub is now PCI DSS v4.0 compliant with our 4.0 service provider attestation available to customers

GitHub’s Payment Card Industry Data Security Standard (PCI DSS) v4.0 service provider Attestation of Compliance (AoC) as well as the corresponding shared responsibility matrix has been completed. This report is the first time GitHub has provided a PCI DSS service provider report for our customers. This enables customers to meet their own PCI DSS compliance needs using GitHub as part of their development environment.

Going forward, GitHub intends to provide this attestation of compliance each year.

If you’re an Enterprise customer and need to obtain copies of GitHub’s AoC or Shared Responsibility Matrix, please reach out to your account manager.

Actions Performance Metrics are generally available and Enterprise-level metrics are in public preview

Performance Metrics for GitHub Actions are now generally available for repositories and organizations. Repository members can view workflow and job performance data including queue times and failure rates going back as far as one year. Organization members can also view this data aggregated across all repositories in their organization. These metrics are available on all GitHub Cloud plans.

In addition, usage and performance metrics aggregated at the Enterprise level are now available in public preview to Enterprise admins. This includes usage metrics (ex. jobs run and minutes used), as well as performance metrics (ex. job failure rates and queue times) across all repositories and organizations in an enterprise. These metrics can be found in the Enterprise UI under the “Insights” tab.
