OpenClaw shipped version 2026.3.22 today, and the release notes read like the team decided to clear out a year’s worth of backlog in one shot. There’s a native plugin marketplace, a long-overdue timeout fix, expanded model support, a substantial security patch batch, and the final closure of the MoltBot rebrand saga. This one has breaking changes — read carefully before you update.

The Headliner: ClawHub Plugin Marketplace

The biggest architectural addition in this release is ClawHub — a native plugin marketplace baked directly into the OpenClaw runtime. Previously, extending OpenClaw meant hunting down npm packages or manually managing skill directories. ClawHub centralizes this: you can now browse, install, and update skills and plugins from a curated registry without leaving the tool.

Breaking change to note: ClawHub now takes priority over npm when you run openclaw plugins install. npm still works as a fallback, but if you had scripts or CI/CD pipelines that relied on npm-install behavior for OpenClaw plugins, those need to be reviewed.

The first major third-party ClawHub integration is already live: Hitem3D’s image-to-3D generation model is now available as a callable skill — a solid showcase for what the marketplace enables.

48-Hour Agent Sessions: Finally Fixed

This one has been a pain point for anyone running long agentic workflows. The default agent timeout was set to 600 seconds (10 minutes), meaning long-running sessions would silently die mid-task regardless of what they were doing. OpenClaw v2026.3.22 bumps the default to 48 hours.

No configuration changes required — it’s automatic. This is a quiet fix with massive practical impact for anyone orchestrating multi-stage pipelines, overnight research jobs, or extended autonomous workflows.

GPT-5.4 and Multi-Model Expansion

The model roster gets a significant update:

  • GPT-5.4 is now supported natively
  • Claude via Google Vertex AI is natively integrated (previously required custom connector work)
  • MiniMax M2.7 replaces M2.5 as the default model
  • Exa, Tavily, and Firecrawl are now bundled as first-party web search plugins

The Vertex AI integration is particularly notable for enterprise teams that route their Anthropic usage through Google Cloud infrastructure — they can now use Claude directly without custom workarounds.

Security Hardening: A Serious Patch Batch

The security section of this changelog is long, and several of the fixes are significant:

  • Windows SMB credential leak: A flaw that could allow remote file:// URLs to trigger outbound SMB handshakes — potentially exposing Windows credentials — is now patched.
  • Invisible Unicode padding: Hidden Unicode characters could be used to conceal text within exec approval prompts, creating a prompt injection vector where users approve what looks like a safe command but contains hidden instructions.
  • Device pairing and webhook authentication gaps: Several holes in how OpenClaw authenticates paired devices and incoming webhooks have been closed.

Multiple fixes in this batch were researcher-reported, which signals a maturing vulnerability disclosure process.

Browser Tooling Breaking Change

The legacy Chrome extension relay path has been fully removed. If you were still using the old browser control flow, you’ll need to migrate. Run openclaw doctor --fix and it will handle the transition automatically.

MoltBot Is Finally Gone

The MoltBot rebrand to OpenClaw has been underway for a while, but previous releases left remnants scattered across runtime internals, installers, and state directories. v2026.3.22 completes the cleanup:

  • CLAWDBOT_* and MOLTBOT_* environment variable names are gone for good — switch to OPENCLAW_* equivalents now if you haven’t already
  • State directories and config paths have been migrated
  • All references in documentation and internal tooling have been updated

If you have any automation scripts, .env files, or config management that references the old names, update them before upgrading.

Android Gets Love Too

Mobile users aren’t left out in this release. Android gains:

  • SMS search
  • Call log search
  • System-aware dark theme

WhatsApp gateway startup times — which had ballooned to tens of seconds — are back to normal after lazy-load fixes. This is directly related to the dashboard/WhatsApp regression that was reported in the npm tarball (see our separate how-to guide for the fix if you hit it).

Bottom Line

This is the release where OpenClaw consolidates from “promising but rough” to “serious platform.” The ClawHub marketplace changes the ecosystem story, the 48-hour sessions fix unblocks real production workflows, and the security patch batch addresses issues that have been visible for months.

If you’re running OpenClaw in production, check the breaking changes (ClawHub install priority, Chrome extension removal, MoltBot env vars) before updating. If you’re evaluating the platform, this is the version to evaluate against.
