Devs and agents are moving faster than ever. Secret protection needs to keep pace.

GitHub’s new context-aware classifier checks candidate secrets in under 2 milliseconds and could more than double the number of secrets push protection prevents before they enter repository history.

What happens when low-quality contributions become one of the biggest pain points for open source maintainers?

Camilla Moraes from GitHub’s Tiny Wins team joins the latest GitHub Podcast to talk about tackling the AI slop problem, listening to maintainers, and deciding what to fix next.

⚡️ @AnthropicAI's Claude Haiku 5.5 is now generally available in GitHub Copilot.

➡️ It's a lightweight model designed for fast, high-volume work like subagents, quick edits, and terminal tasks.
➡️ Our early testing showed that it matched Claude Sonnet 5 on many coding tasks while using significantly fewer tokens and steps.

Try it out in the GitHub Copilot app, CLI, or @code.

Local sandboxing for GitHub Copilot is now generally available 🙌

This allows Copilot to run commands in an isolated environment with controlled access to files, networks, system capabilities, and credentials so you have more granular control. It also gives enterprise teams a way to centrally manage policies.

Try it out in GitHub Copilot CLI, GitHub Copilot app or @code. github.blog/changelog/2026…

We're bringing local models and sandboxed tools to Windows and GitHub Copilot

Coming soon, GitHub Copilot will determine when a task is best handled by on-device intelligence and when it should leverage cloud-scale models.

📣 Coming soon to GitHub Copilot: intelligent local model routing.

We are excited to announce the next step in our Project HydraFusion vision. GitHub Copilot will soon be able to automatically route tasks to a local model when it's most suitable, helping you save on AI credits.

Something new is coming from Windows x.com/i/broadcasts/1…

Git activity more than doubled between September 2025 and August 2026, reaching 473.3B events per month.

We’re rebuilding our Git infrastructure while GitHub keeps running, creating a foundation for agent-scale software development. x.com/i/article/2107…

How do you know whether an AI code reviewer catches the issues that matter without adding noise?

ReviewBench is a new open benchmark shaped by analysis of 103.9M GitHub pull requests, with 219 PRs across 19 languages.

Bring your own code review agent, evaluate it, and submit your results ⬇️

Git 2.56 is here. ⚡ The new git add --resolved stages only paths that are still marked as conflicted, and refuses to stage them if conflict markers remain. One merge-base case dropped from 0.68s to 0.01s.

The highlights 👇

Cool it on the tab hopping 🐇

Reviewing agent code usually means switching tabs. The GitHub Copilot app puts the diff, terminal, and browser side by side to check, run, and preview.
