OpenClaw just shipped version 2026.3.28, and if you run agentic pipelines on this platform, you need to read the release notes carefully. This is one of the more architecturally significant updates in recent months — it introduces async human-in-the-loop (HITL) tool approvals, drops the Qwen portal auth integration entirely, and ships a handful of other meaningful improvements. Let’s unpack what changed and what it means for your deployments.

Async Human-in-the-Loop: The Headline Feature

The biggest change is the addition of requireApproval as an async hook in OpenClaw’s before_tool_call plugin system. In practical terms, this means plugins can now pause tool execution mid-flight and prompt the user for explicit approval before the tool actually runs.

This is a significant safety architecture shift. Previously, HITL gates in agentic pipelines required custom workarounds — either baking approval logic into the agent’s own prompting, or building separate orchestration layers to intercept tool calls. Now it’s first-class infrastructure.

The approval prompt surfaces across all major channels: the exec approval overlay in the terminal UI, Telegram inline buttons, Discord interactions, and the /approve command on any connected channel. The /approve command now also handles both exec-level approvals and plugin-level approvals, with automatic fallback handling.

For teams running agents that interact with production systems — databases, file systems, external APIs — this is the safety layer that closes a real gap. Agents can now be trusted to handle more of a workflow autonomously while still surfacing high-stakes decisions to a human before executing.

Breaking Change: Qwen Portal Auth is Gone

This is the update that will break existing deployments if you haven’t prepared: Qwen portal auth has been removed. The deprecated qwen-portal-auth OAuth integration for portal.qwen.ai is no longer supported.

If you’re running OpenClaw with a Qwen model configured via portal auth, you must migrate. The path forward is OpenClaw’s Model Studio integration:

openclaw onboard --auth-choice modelstudio-api-key

There’s also a secondary breaking change: the Config/Doctor no longer automatically migrates legacy config keys older than two months. Very old keys will now fail validation rather than being silently rewritten on load. Run openclaw doctor on any older installation to surface and fix these before they cause runtime failures.

xAI / Grok Gets First-Class x_search

The xAI provider has been migrated to the Responses API, and x_search — Grok’s native X/Twitter search capability — is now a first-class bundled tool. The xAI plugin auto-enables from existing web-search and tool config, which means if you already have Grok configured, x_search becomes available without manual plugin toggles. During openclaw onboard and openclaw configure --section web, you’ll now get the option to set up x_search with a model picker.

MiniMax Image Generation

MiniMax support lands in this release with an image generation provider for the image-01 model. It supports standard generate workflows plus image-to-image editing with aspect ratio control.

ACP Current-Conversation Binds

A useful quality-of-life improvement for ACP sessions: current-conversation binds are now available for Discord, BlueBubbles, and iMessage. The /acp spawn codex --bind here command can now turn the current chat thread into a Codex-backed workspace without spawning a child thread. The documentation now explicitly distinguishes between chat surface, ACP session, and runtime workspace — a distinction that was previously underdocumented.

What to Do Right Now

  1. Migrate Qwen auth — run openclaw onboard --auth-choice modelstudio-api-key if you use Qwen models
  2. Audit your config — run openclaw doctor to catch any legacy keys before they cause validation failures
  3. Review your plugins — if you’ve built custom before_tool_call hooks, check whether you want to adopt requireApproval for higher-stakes tool calls
  4. Test your HITL gates — the new async approval system needs channel-specific testing to confirm your preferred approval surface (terminal, Telegram, Discord) is working as expected

The full release notes are on GitHub. This is a release worth upgrading to promptly — especially given the CVEs disclosed in today’s separate advisory (covered separately on this site).
