2.1.1 June 22, 2026 Model quota screen and agent security fixes New model quota screen, agent permission and security fixes, and MCP stability improvements Improvements (1) Quota screen redesign: clearer, unambiguous view into “used” versus “remaining” credits in the Models tab of the Settings screen. Fixes (4) Fixed Agent Permission Issue: Fixed the bug where changes to the agent security mode were not persisted. Improved MCP server stability: increased resilience to unresponsive MCP servers and improved browser agent self-troubleshooting abilities when using the Chrome DevTools MCP server. MCP server schema compatibility: the mcp_config.json schema now accepts url in addition to serverUrl as a field. New entries in the sensitive paths list: .vscode and .cache are now recognized as sensitive paths that require explicit user confirmation before the agent can access them in strict mode.

Patches (0) 2.0.3 May 21, 2026 Migration flow from Antigravity 1.0 Added a migration flow that allows users to import customizations

• Improved compatibility with a broader set of ARM64 devices (e.g. raspberry pi 4b).
• Added antigravity_guide builtin skill to provide instant, in-context reference guides for the Antigravity 2.0, CLI, IDE, and SDK.
• Improved commit history navigation: scrolling now immediately loads and displays changed files and diffs.
• Improved Git integration by enabling ASCII node graphs (git log --graph) for visual parity with hg/jj.
• Improved commit hash matching to seamlessly resolve short (6-char) to long (64-char) hashes via prefix comparison.
• Added alert message type for system errors/warnings, separating them from standard command output.
• Added the CLI log file path to the /help menu for easy troubleshooting.
• Improved markdown rendering by upgrading glamour to v2.0.1 for cleaner headings and block padding.
• Improved authentication to automatically launch browser sign-in via rundll32.
• Fixed a bug where "ask" permissions were dropped during settings updates, ensuring settings.json preservation.
• Fixed permission engine matching bugs by escaping regex metacharacters (like $ or .) in saved rules, preventing infinite prompt loops.

0.1.4 June 18, 2026 Async tool execution buffers, memory state persistence, and error handling improvements This release introduces major architectural refactorings, public API standardizations, and key new capabilities centered on centralizing model configurations to natively support multi-model backends, exposing a new built-in Google Web Search capability, enabling environment variable passing for Model Context Protocol (MCP) servers, and simplifying the agent initialization flow by removing dynamic runtime registrations. Improvements (10) Built-in Web Search Tool : Exposes the SEARCH_WEB tool directly within the SDK, enabling agents to leverage Google Search for grounded real-time information retrieval, complete with new developer examples ( web_tools.py ). MCP Server Environment Variables : Added support for configuring and passing custom environment variables to launched stdio servers via the new env field in McpStdioServer . Base URL and HTTP Headers Support : Out-of-the-box support for setting custom base URLs and HTTP headers. Image Generation Aspect Ratio : Updated the SDK model config and wrapper to support specifying aspect_ratio within the image creation tool

• Added submodule support for plugins installation. External plugin installation now automatically resolves and initializes Git submodules.
• Optimized customizations permissions: Automatically grants read-only access to the builtin customizations directory, eliminating redundant permission prompts on startup.
• Improved glamour parser error handling (like nested checkboxes inside list emphasis) and preventing it from crashing the TUI, falling back to raw text with a warning banner.
• Updated bubbletea to v2.0.7: Resolves a potential TUI panic when terminal input is unavailable, fixes a data race in mouse handling within the Cursed Renderer, and corrects mouse release behavior under the Kitty Keyboard protocol.
• Hardened command execution permission checks by enforcing strict exact-match verification for PowerShell scripts, complex shell redirections ( > , 2>&1 ), and unparseable strings to prevent sandbox escapes.
• Hardened sandbox execution by adding .git to the core list of dangerous paths, preventing unauthorized or destructive repository modifications.

• Added support for capturing slash command history, allowing users to use the up arrow to replay previously entered slash commands.
• Redesigned the "Models & Quota" page (enabled by default, replacing the legacy usage page) to gracefully handle disabled quota buckets by displaying a dimmed "Disabled" status and omitting the progress bar.
• Added display of quota usage and execution mode in the status line.
• Improved /btw to be more token efficient and support streaming responses for a smoother user experience and fixed premature truncation.
• Fixed a bug where the /hooks command wrote configurations to ~/.gemini/antigravity-cli/hooks.json instead of the shared ~/.gemini/config/hooks.json, ensuring hooks remain synchronized between the TUI and the backend.
• Fixed a CPU compatibility issue (SIGILL on non-AES-NI CPUs), preventing immediate crashes on startup on older CPUs (like Intel Ivy Bridge) or VM environments that lack AES-NI support.
• Added a per-line guard against extremely long single-line pastes in the TUI prompt editor to prevent performance lag, replacing them with an expandable placeholder.

2.1.4 June 11, 2026 Quota Screen Redesign and PDF Support Quota screen redesign, PDF attachment support, new /btw slash command, and other bug fixes Improvements (7) Quota screen redesign: clearer, unambiguous view into “used” versus “remaining” credits in the Models tab of the Settings screen. Ask side questions via /btw: while in a conversation, type ‘/btw’ in the input and select the ‘btw’ option in the menu to write a message to an ephemeral, single-response agent that has the context of your current conversation. Simple conversation search functionality: cmd/ctrl+F to search for visible text in the conversation view. Support for PDF attachments to messages to Gemini models: drag and drop PDFs from your filesystem or add PDFs using the media option in the Add Context menu button in the input box. Breadcrumbs in file viewer pane header: quality-of-life UI to more easily see and navigate directories in your repo. Nested subagents in the overview pane: see all nested subagents belonging to the main conversation instead of only the subagents that are one level deep. Minor improvements to Projects UX: you can now specify a project name during the creation flow and sort

0.1.3 June 11, 2026 Initial subagent orchestration and standard Google AI model targets This release introduces per-server MCP timeout configurations and improves local connection error handling. Improvements (2) Per-Server MCP Timeout : Added configuration support to set custom timeouts (in seconds) for individual MCP servers ( BaseMcpServerConfig.timeout_seconds ). Terminal Error Propagation : The local connection now propagates terminal trajectory errors from the localharness binary as structured AntigravityExecutionError exceptions in the Python SDK during step collection. Fixes (0) Patches (0) 0.1.2 June 4, 2026 Google Antigravity SDK release 0.1.2 updates This release adds Windows platform support, introduces programmatic turn-level stream cancellation, simplifies safety policy configurations for the Model Context Protocol (MCP), and removes the deprecated MCP SSE transport. Improvements (3) Windows Platform Support : Native compatibility added for Windows x86_64 and ARM64 environments. Path and file URI resolution now correctly handles drive letters and directory separators under Windows. Programmatic Turn-Level Cancellation : Added programmatic stream cancellation via

• Added a configurable timeout for launching MCP servers, allowing users to specify a custom timeout or set it to -1 to disable the timeout completely.
• Revamped the artifact viewer gutter numbering and line mapping to accurately align terminal viewport lines with actual 1-based source file line numbers, including support for wrapped lines and collapsed Mermaid diagrams.
• Fixed a bug where the CLI could get stuck in a pending state (showing a transient spinner) after sending a message due to stale status updates.
• Fixed a bug where the wrong workspace directory was displayed in the header and /help menu when multiple workspaces were active.
• Fixed a desync bug in the agent state management where stale callbacks from previous runs could be used upon cache hits in new agent state.
• Fixed Windows-specific sandbox network proxy issues, resolving a hang during connection hijacking and correcting tunnel response protocols.
• Fixed a bug where the archival status timestamp was not correctly saved when archiving conversations.
• Fixed a potential stack overflow crash by introducing a non-recursive warning output mechanism for pre-conversation errors.

• Added shell-style path auto-completion for /open and /add-dir.
• Added optimistic rendering for user chat prompt submissions, injecting messages immediately into the viewport to eliminate perceived input lag.
• Added fuzzy and partial substring matching across slash commands. E.g. /el -> shows /help and /model while previous no suggested completions.
• Fixed a bug when suggestion was not triggered when @ is typed after (. Enabled unconditional typeahead suggestions whenever @ is typed without preceding whitespace, streamlining mention workflows.
• Skipped subagent conversations from /resume, keeping the standalone conversation picker focused purely on direct user initiated conversations.
• Added a stack_with_default flag to the statusLine configuration to render both the default Antigravity status line and custom status line output vertically stacked.
• Fixed a bug where entering a prompt immediately after pressing Esc (to interrupt an active agent stream) caused the newly typed input to be swallowed or rejected.

0.1.2 June 4, 2026 Google Antigravity SDK release 0.1.2 updates This release adds Windows platform support, introduces programmatic turn-level stream cancellation, simplifies safety policy configurations for the Model Context Protocol (MCP), and removes the deprecated MCP SSE transport. Improvements (3) Windows Platform Support : Native compatibility added for Windows x86_64 and ARM64 environments. Path and file URI resolution now correctly handles drive letters and directory separators under Windows. Programmatic Turn-Level Cancellation : Added programmatic stream cancellation via ChatResponse.cancel() . This programmatically aborts active generation turns directly from the client and raises AntigravityCancelledError (subclass of asyncio.CancelledError ) to cleanly signal cancellation in the async flow ( examples/getting_started/cancellation.py ). Direct MCP Safety Policy Configuration : Overloaded policy.allow , policy.deny , and policy.ask_user to accept server configurations ( BaseMcpServerConfig ) directly instead of typing namespaced string paths. Policy evaluation follows a 9-level precedence model (Specific > Prefix Wildcard > Global Wildcard) with longest-match prefix

• Added --model to set model when launching CLI. Also a new models subcommand to list available models.
• Added /permissions command which allows to add/edit/remove permissions rules for each of the three configs above directly inside the CLI.
• Allowed opening the Artifact Review panel (shortcut ctrl+r) while answering pending questions or tool permission confirmations, preserving your current progress when toggling back.
• Fixed a bug that metadata was written in the current directory as opposed to ~/.gemini/antigravity-cli/cache when running using -p.
• Improved statusline layout by merging active tip and artifact status on a single line and truncating with ellipsis on narrow terminals to prevent collisions.
• Improved customization support by allowing directories in the customization manager to be passed as workspace directories, enabling correct trajectory metadata population and /add-dir support.
• Added support for url in mcp_config.json to configure MCP servers directly via a URL.

• Added SQLite (.db) conversation support and will be CLI’s conversation format. Fixed a bug when importing SQLite conversation from Antigravity 2.0 to CLI.
• Added LaTeX math rendering, enabling the CLI to display beautiful mathematical formulas directly in the terminal viewport. Set AGY_CLI_DISABLE_LATEX environment variable to turn off LaTeX rendering globally if desired.
• Decoupled project discovery from local .antigravitycli workspace directories. The CLI now stores workspace-to-project mappings in a centralized ~/.gemini/antigravity-cli/cache/projects.json file, eliminating repository clutter and speeding up project discovery to a single-map lookup.
• Resolved sporadic and permanent UI hangs caused by a stateful callback streamer race condition during network drops or extremely fast agent steps.
• Collapses all newlines and consecutive whitespaces in conversation previews and titles before rendering list items, preventing visual UI layout breaks in the picker rows.
• Styled the separator space between the line number column and diff content to match the text blocks, ensuring background highlights stretch seamlessly across the viewport width in tool outputs and /diff

0.1.1 May 29, 2026 Google Antigravity SDK release 0.1.1 updates This release focuses on significant enhancements to the Model Context Protocol (MCP) integration, adds native Vertex AI authentication support, improves robustness with better error handling, and includes critical fixes for token usage tracking. Improvements (4) MCP Tool Filtering & Simplified Policies : Added support for enabled_tools (allowlist) and disabled_tools (denylist) in server configurations, and overloaded safety policy helpers ( policy.allow , policy.deny , policy.ask_user ) to accept the MCP server configuration object directly. Vertex AI Authentication : Integrated native support for Vertex AI authentication in the Python SDK. MCP Tool Prefixing & Validation : The SDK now automatically namespaces and prefixes MCP tools ( mcp_{server_name}_{tool_name} ) to prevent name collisions when connecting multiple MCP servers. The name field is now mandatory in MCP server configurations and validated as a proper Python identifier. Improved Error Handling : The SDK now raises explicit, descriptive exceptions for terminal errors rather than failing silently. Fixes (2) Structured Output Token Tracking : Fixed a bug
