Claude Code 2.1.229 injects SSE keepalive pings into gateway streaming responses during long thinking pauses, preventing silent idle-timeout disconnects on Vertex AI and Bedrock. Plus: /commit-push-pr now blocks dangerous git flags and the sandbox enforces IPv6 fail-closed.
Google Cloud API Gateway model routing is now in Public Preview: a serverless OpenAPI-spec layer that routes Gemini, Claude, and OpenAI requests — but only if all your backends live on Vertex AI.
Claude Code 2.1.211 fixes a prompt-caching billing regression that silently billed the trailing system context block as fresh input tokens on every request across Bedrock, Vertex AI, Mantle, and Foundry. Gateway operators have overcharges to investigate.
Claude Code 2.1.207 removes the CLAUDE_CODE_ENABLE_AUTO_MODE opt-in requirement on Bedrock, Vertex AI, and Foundry. Auto mode is now on by default for all managed-provider sessions — operators must add disableAutoMode to maintain prior behavior.
Claude 3.5 Haiku shut down on Vertex AI yesterday. Claude 3 Opus is deprecated and exits August 1. If your routing policy lists either model on Vertex, you are already failing or will within 26 days.
Google deprecated Vertex AI Extensions on May 26, 2026, with a hard shutdown on November 26. Teams routing agent workflows through Google must migrate their Code Interpreter, Search, and Custom Extensions to the Gemini Enterprise Agent Platform before the deadline.
Vertex AI is not deprecated, but Google is retiring every Imagen 2.x/3.x/4.x and Veo 2.x/3.0 GA endpoint on June 30, 2026. Use this shutdown list to migrate image and video routing to gemini-2.5-flash-image and veo-3.1 endpoints.
Claude Code auto mode now runs on AWS Bedrock, Google Vertex AI, and Microsoft Foundry — set CLAUDE_CODE_ENABLE_AUTO_MODE=1 and your coding agent runs inside your VPC. Here's what changes for billing, latency, and fallback routing when you switch from the Anthropic API.
