Visual Studio Code 1.123
Release date: June 3, 2026
Welcome to the 1.123 release of Visual Studio Code. This release improves how you work with agents and the integrated browser.
Headline features
- Larger context windows: Support for 1M context windows for Anthropic and OpenAI models.
- Session sync: Automatically sync chat sessions across machines and search coding history.
- Agents window: Open multiple agent sessions side-by-side to compare or review work in parallel.
- Research agent: Run deep research on a topic and get a thorough, well-cited Markdown report.
- Integrated browser updates: Favorite pages for quick access and more screenshot capture options.
Session sync and chronicle
VS Code automatically syncs chat sessions to a user’s GitHub account, giving a personal, searchable history across machines and workspaces. Each synced session captures the conversation, files touched, repository context (repository, branch, timestamps), and referenced pull requests, issues, or commits.
The /chronicle command lets users query session history in natural language, generate standup reports, get productivity tips, and search coding history by topic, file, or pull request.
Users enable sync with chat.sessionSync.enabled. Synced sessions are private unless explicitly shared. Copilot Business/Enterprise admins can control sync via GitHub enterprise policy and VS Code group policy CopilotSessionSync.
Agents window
Users can open multiple sessions side-by-side via “Open to the Side,” drag-and-drop, or Alt+click. Sessions can be pinned so they aren’t replaced when selecting another session.
Research agent (Preview)
Available only in Copilot CLI (local) sessions in Insiders. Invoked with /research, it gathers information from codebase, GitHub repositories, and the web to produce a cited Markdown report. Read-only — reports findings without changing code.
1M context window
VS Code supports 1 million token context windows for compatible Anthropic and OpenAI models, including Claude Opus 4.7 and GPT-5.5. Larger context windows may consume more tokens per interaction, increasing AI credits usage under usage-based billing.
Integrated browser
Remodeled address bar with favorites and tab management. New screenshot options: Add Area Screenshot to Chat (selected rectangle) and Add Full Page Screenshot to Chat (experimental, requires workbench.browser.experimentalUserTools.enabled).
Extension update delay
VS Code applies a two-hour delay before automatically updating extensions to newly published versions (protection against compromised releases). Trusted publishers (Microsoft, GitHub, OpenAI) continue to update immediately.
Microsoft released VS Code 1.123 alongside Build 2026, available on Windows, Mac, and Linux.
