Visual Studio Code 1.90 ships with several quality-of-life improvements that have been highly requested by the community. Copilot agent mode is now enabled by default for all Copilot subscribers, allowing multi-file edits and terminal command execution directly from the chat panel. The inline diff preview replaces the previous approach and makes it much easier to review AI-suggested changes before applying them. Python developers benefit the most from this release: VS Code now auto-detects virtual environments in a project root, conda environments, and pyenv shims without any configuration. The Python Debugger extension is now bundled. The extension host has been rewritten to run in a separate process, reducing the impact of poorly behaved extensions on the editor's responsiveness.
