Google Antigravity v0.1.2

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 validation to protect against collisions. Fixes (0) Patches (1) Deprecation of SSE Transport : Removed the legacy McpSseServer configuration and connection handlers in favor of standard Stdio and Streamable HTTP connection strategies. 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
