OpenClaw v2026.3.28 shipped with three notable changes.
xAI Grok Web Search
The bundled xAI provider moved to the Responses API, which enables native x_search support. Your OpenClaw agent can now browse the web through Grok's own search infrastructure. Existing xAI configs get automatic plugin activation. New installs can set it up via openclaw configure --section web.
The Web Search Key Audit also expanded to recognize credentials for Gemini, Grok/xAI, Kimi, Moonshot, and OpenRouter.
MiniMax Image Generation
MiniMax joined as a second image generation provider alongside DALL-E, using their image-01 model. Supports text-to-image and image-to-image editing with aspect ratio controls. Setup takes about two minutes via openclaw configure --section image.
Config Doctor Gets Stricter
Legacy configuration migrations older than two months now fail validation instead of silently rewriting old config keys. Self-hosted users need to run openclaw doctor --fix before upgrading. Managed instances (like ClawHosters) handle this automatically.
Also in this release: Qwen deprecated its qwen-portal-auth OAuth path and migrated to Model Studio, and the legacy Chrome extension relay for Browser Chrome MCP was removed.
