Claude Sonnet 5 is Anthropic’s latest Sonnet-class model, now available in GitHub Copilot. It brings strong coding performance to everyday development and agentic workflows, giving developers a new Sonnet-class option for tasks across the IDE and CLI.
You can now use branch rulesets to block pull requests from merging when test coverage drops below thresholds you set. You can set a minimum coverage percentage, a maximum allowed drop from the default branch, or both. You can start in evaluate mode to understand impact first, then switch to active mode when you’re ready to enforce merge protection.
You can now scan and navigate release pages more easily with a dedicated sidebar table of contents. We also updated release metadata placement for a more consistent layout so it’s easier to move between entries on long pages. Users with write access can also now see download counts per release asset directly in the Releases UI.
Claude Opus 4.8 (fast mode) is now rolling out in preview on GitHub Copilot. Fast mode delivers significantly faster output token speeds while maintaining the same intelligence as Claude Opus 4.8, making it well suited for interactive coding and agentic workflows where responsiveness matters.
Repository admins can now restrict issue creation to collaborators with write access. This gives you more control over who can open issues and helps reduce unwanted issue creation, while keeping issue workflows available to the people who actively maintain and contribute to the project.
MAI-Code-1-Flash, Microsoft AI’s in-house coding model, is now generally available for GitHub Copilot Business and Copilot Enterprise, building on its recent expansion across Copilot surfaces .
You can now create up to 1,000 cost centers per enterprise, up from 500. Enterprises that model hundreds or thousands of business units, departments, or product groups can now represent that full structure in GitHub, instead of exporting usage data into a homegrown system to fill the gap.
GitHub Actions now issues read-only cache tokens to the default branch for workflow events that can be triggered without write permissions to the repository. This applies least privilege to the cache and prevents common privilege-escalation paths through cache poisoning.
Copilot code review now uses the built-in file exploration tools available in the Copilot CLI and SDK, significantly improving review cost efficiency with no change to your existing workflow. If you’re in the Medium analysis depth public preview, you’ll also see some new updates centered around configurability and visibility of review depth.
Copilot Free and Student plans will now use Copilot auto model selection as the default and only model selection experience. Auto dynamically selects the best model for each task, removing the need for manual choice. Auto provides access to models across multiple model families, subject to plan restrictions.
For a timely response to security incidents involving compromised accounts or stolen credentials, GitHub Enterprise owners can now use new “break-glass” capabilities to instantly revoke all credentials for a given user. This builds on the enterprise-wide credential management tools for incident response released earlier.
