Anthropic Claude Sonnet 4.5 is in public preview for GitHub Copilot Claude Sonnet 4.5, Anthropic’s most advanced model for coding and real-world agents, is now rolling out in GitHub Copilot to Copilot Pro, Pro+, Business, and Enterprise. From our early testing, the model brings major upgrades in tool orchestration, context editing, and domain-specific capabilities. Availability in GitHub Copilot C

Pull request “Files changed” public preview now supports commenting on unchanged lines We have a major update to announce to the new pull request “Files changed” page: you can now comment anywhere in a changed file! 🎉 This feature and the new “Files changed” page are both in public preview. 💬 Comment anywhere in a changed file Using the new “Files changed” page, you can now comment on any line o

Copilot coding agent, our asynchronous, autonomous developer agent, is now generally available for all paid Copilot subscribers. Delegate a task to Copilot, and Copilot will open a draft pull request and work in the background in its own development environment. It does this through the power of GitHub Actions. Once Copilot is done, it will request a review from you, and you can ask Copilot to mak

This year marks 20 years since Git’s first commit. Since then, it’s become the default version control system for everything from weekend side projects to the largest monorepos in the world. But Git’s evolution didn’t stop at git init. Every year, contributors continue to improve Git’s performance, UX, and interoperability while new tools and use cases push it into unfamiliar territory. More than

Open source software is the bedrock of the modern software industry. Its collaborative nature and vast ecosystem empower developers worldwide, driving efficiency and progress at an unprecedented scale. This scale also presents unique vulnerabilities that are continually tested and under attack by malicious actors, making the security of open source a critical concern for all. Transparency is centr

Currently selected: Reuse workflow configuration with YAML anchors Reuse workflow configuration with YAML anchors GitHub Actions now supports YAML anchors, a top request from the GitHub community. With YAML anchors, you can reuse configuration across your workflows and ensure better conformance with the YAML spec. This feature is automatically enabled for all GitHub Actions users and reposit

If you’ve tried connecting AI agents to your development tools, you know the pain: MCP servers scattered across numerous registries, random repos, buried in community threads — making discovery slow and full of friction without a central place to go. Meanwhile, MCP server creators are worn out from publishing to multiple places and answering the same setup questions again and again. The result is

Today, we’re announcing some changes that will improve the security of accessing Git data over SSH. What’s changing? We’re adding a new post-quantum secure SSH key exchange algorithm, known alternately as sntrup761x25519-sha512 and sntrup761x25519-sha512@openssh.com, to our SSH endpoints for accessing Git data. This only affects SSH access and doesn’t impact HTTPS access at all. It also does not a

GitHub Copilotの進化するモデルとインフラが、開発者が選択できることを中核として、主体的なワークフローを可能にする仕組みを解説します。 2021年6月にテクニカルプレビューを発表して以来、GitHub Copilotは大きく進化し、それを支えるAIモデルも進化しています。 最初にGitHub Copilotを発表したとき、OpenAIはまだChatGPTを立ち上げていませんでした。今日、AIはニュースの見出しや開発ワークフローにあふれています。この急速な変化の中で、私たちの目的は変わりません：開発者が開発に集中してより多くのことを達成することです。 そんな中、私たちは開発者のことを考え、GitHub Copilotの継続的な改善に注力してきました。それは、GitHub Copilotの動力となっているモデルを再評価し、エージェント型ワークフローをGitHub Copilotのエ

If you’ve read any of my stuff or listened to one of my presentations before, you’ve likely heard my snarky joke: “Don’t be passive aggressive with Copilot.” My point with this joke is serious, though. Copilot works best when you give it the right context. Just like a new teammate, it can’t read your mind (even if it sometimes feels like it can). Copilot can likely figure out what you’re doing and

As coding agents have grown more powerful, a pattern has emerged: you describe your goal, get a block of code back, and often… it looks right, but doesn’t quite work. This “vibe-coding” approach can be great for quick prototypes, but less reliable when building serious, mission-critical applications or working with existing codebases. Sometimes the code doesn’t compile. Sometimes it solves part of
