GitHub Announces September 2026 Updates for Copilot in Visual Studio
According to GitHub. The latest update introduces enhanced pull request exploration, expanded model support, and automated vulnerability remediation tools.
- • New Git agent enables direct pull request summaries and navigation within Copilot Chat.
- • BYOM feature now supports Microsoft Foundry, OpenAI, Anthropic, and Ollama models.
- • Integrated NuGet vulnerability fixes are now accessible directly from the Error List.
Git Agent Integration
GitHub has launched a new Git agent for Visual Studio, designed to help developers explore pull requests without leaving the chat interface. By connecting to Git provider MCP servers, users can generate summaries and navigate directly to relevant comments and files, streamlining the code review process.
Expanded Model Flexibility
The Bring Your Own Model (BYOM) feature has been updated to support a wider range of providers, including Microsoft Foundry, OpenAI, Anthropic, and Ollama. This preview feature requires the new Agent (Preview) harness, and GitHub notes that previous configurations for Ollama models will need to be re-added following the update.
Automated Security Fixes
Visual Studio now provides a direct path to remediate NuGet vulnerabilities. When the Error List flags a vulnerable package, users can trigger a fix action that utilizes the NuGet MCP server and GitHub Copilot Chat to generate and apply necessary security patches.
