Google Antigravity IDE Extensions 1.0.0

Changelog: Initial 1.0.0 release of Antigravity for VS Code with agentic chat, in-editor inline diffs, interactive plan review, and Remote-SSH support

Introduces the 1.0.0 release of Antigravity for VS Code, bringing an agentic AI coding assistant with sidebar chat, in-editor inline diff review, interactive implementation plan artifacts, and Remote-SSH workspace support.

Improvements(8)

• Added automatic installation, integrity verification, and channel-aware updates for the local Antigravity backend server.
• Added the Antigravity sidebar chat view with keyboard shortcuts to add editor selections to chat (Cmd+L / Ctrl+L), toggle chat focus (Cmd+L / Ctrl+L), start a new conversation (Cmd+Shift+L / Ctrl+Shift+L), accept (Alt+Enter) or reject (Alt+Shift+Enter) agent steps, and interrupt the agent (Escape).
• Added in-editor inline diff decorations and CodeLens actions (Accept / Reject) for reviewing agent code changes, along with Accept All Changes, Reject All Changes, and Antigravity: Toggle Inline Diff (antigravity.enableInlineDiff) to switch between inline and side-by-side diff views.
• Added the Antigravity Artifact Viewer custom editor for previewing, commenting on, and approving agent implementation plans and Markdown artifacts, along with support for exporting conversations.
• Added automatic port-forwarding resolution and tunnel connection retry support for VS Code Remote-SSH and remote development workspaces.
• Scoped conversations to the active workspace folder and preserved pending conversation state when opening or switching workspace folders.
• Synchronized VS Code theme colors and editor font families with the Antigravity chat view, and added support for right-click context menus, native Cut/Copy/Paste shortcuts, and mouse back/forward navigation.
• Added the Antigravity: Reset Conversation State and Antigravity: Show Third Party Notices commands, dedicated Antigravity and Antigravity LS output channels, and streamlined extension settings.

Fixes(5)

• Fixed OAuth sign-in browser launch, post-login callback focus, and authentication state revalidation across Antigravity views.
• Fixed Cmd+L / Ctrl+L so it reliably focuses the chat input when opening the Antigravity sidebar and toggles the sidebar closed when the chat input is already focused.
• Fixed agent diff handling so switching conversations or editing files externally preserves user changes in a read-only diff view instead of overwriting the file, and prevented background agent edits from stealing editor focus.
• Fixed the Proceed button in planning mode, directory navigation in the VS Code Explorer, and BigInt message serialization in webview communication.
• Addressed other minor user interface issues.
