This week, GitHub Copilot expands model choice and content protections, while VS Code adds new ways to manage agent sessions and get pull requests merge-ready.

GitHub Copilot app and Copilot CLI

Copilot app and CLI now honor content exclusions, keeping sensitive code out of context across agentic workflows.

The GitHub Copilot harness is now generally available in Copilot for JetBrains, providing faster feature delivery and better code quality.

VS Code 1.136 release updates

Agent Merge is now in public preview and gets your pull request ready to merge by resolving review feedback, failed checks, and merge conflicts.
Multi-root workspaces are now experimental and bring Copilot and Claude agent sessions to every folder in your workspace.
Chat backgrounds are now experimental and let you personalize the Agents window with built-in patterns or your own images.
Chat sessions organize related chats into a hierarchy and show which ones need your attention.

Explore everything that’s new in the full release notes.
