OpenClaw Release v2026.3.28: OpenAI/Codex apply_patch Enabled by Default, Introducing xAI x_search, and MiniMax Image Generation

According to 1M AI News monitoring, the open-source AI agent tool OpenClaw has released v2026.3.28. This version includes two breaking changes: removal of the deprecated Qwen OAuth integration for portal.qwen.ai and discontinuation of automatic migration for configurations older than two months, where legacy keys will now fail validation directly. The new version also switches the built-in xAI provider to the Responses API, introduces first-class x_search, adds MiniMax image-01 image generation and graph editing, supports plugin asynchronous requireApproval approval flow, and enables apply_patch by default for OpenAI and OpenAI Codex models. Additionally, this update includes supplementary Gemini CLI backend support and fixes for Anthropic termination reasons crashes, Gemini 3.1 alias resolution, and Codex image understanding.
