🚀 The latest VS Code release makes the Copilot SDK-based harness the default for new sessions, adds model comparisons, and brings a file list to multi-file diffs. 🧵 Here’s what’s new: code.visualstudio.com/updates/v1_143

🤖 Use the same Copilot session in the editor and Agents window. New sessions default to the Copilot harness, built on the Copilot SDK to help align behavior, capabilities, and improvements across Copilot products.

🧠 Compare model results and combine ideas with Synthesize (Preview) In the Agents window, enable ⚙️ sessions chat compareAgents enabled, then select Compare Models in the model picker to run the same task across models.

🧹 Reclaim disk space from inactive agent worktrees (Experimental) In the Agents window, run Chat: Open Worktree Cleanup to review sizes and remove worktrees you no longer need. Cleanup marks the selected sessions as done and deletes their worktrees.

📄 Jump between changed files without scrolling through every diff (Experimental) Enable ⚙️ multiDiffEditor experimental fileList, then select a file in the list beside the multi-file diff editor to jump to its changes.
