OpenClaw v2026.5.2 dropped today, and it’s the kind of release that actually earns the “less drama, more uptime” tagline. Grok 4.3 is now bundled as the default xAI chat model, over 200 fixes landed across plugins and gateway performance, and the community’s post-upgrade headaches finally have an official fix command. This guide walks you through the upgrade and explains what’s new.

What’s In This Release

The headline addition is xAI Grok 4.3 as the new default model for the xAI chat integration. Compared to its predecessor, Grok 4.3 brings a 1-million-token context window, improved tool-use reliability, and more competitive pricing — the kind of improvements that compound fast when you’re running agents that do real work.

The broader release wraps 200+ fixes across three main areas:

  • Plugin stability: Sturdier npm, Git, and ClawHub installs that were prone to breakage on network hiccups or partial upgrades
  • Gateway performance: Faster startup times, cached tool manifests, and lighter session footprints
  • Messaging connectors: Restart-safe Discord integration, Slack DM and file upload fixes, Telegram topic support, and WhatsApp newsletter compatibility

Community members reported some fragility immediately post-upgrade — particularly around plugin states — which is exactly what the new openclaw doctor --fix command is designed to address.

Step 1: Pull the Update

Use your standard upgrade path. If you installed OpenClaw via npm:

npm update -g openclaw

Or via the OpenClaw CLI’s built-in update mechanism — refer to the official release notes for the exact command appropriate for your install method, as the syntax may vary based on whether you’re using a system install or a local environment.

After upgrading, confirm the version:

openclaw --version

You should see 2026.5.2.

Step 2: Run the Health Check

Before doing anything else, let the doctor fix any post-upgrade issues:

openclaw doctor --fix

This command was specifically added in v2026.5.2 to address the post-upgrade fragility that community members flagged. It checks plugin states, gateway configuration, and connector health, then automatically repairs common issues it finds. Run it once after every major upgrade — it’s fast and idempotent.

Step 3: Set Grok 4.3 as Your Default xAI Model

Grok 4.3 is bundled as the default xAI model in this release, so if you were already using the xAI integration, it should activate automatically. To verify — or to explicitly configure it — consult the official v2026.5.2 release notes for the exact config key and syntax to use with openclaw config get or openclaw config set. The release notes include the canonical configuration path for the xAI model default — don’t guess at key names; the official docs are authoritative here.

Step 4: Audit Your Plugins via ClawHub

One of the quieter improvements in this release is plugin externalization via ClawHub — OpenClaw’s skill/plugin registry. Skills that previously shipped bundled in the core package are now installable on-demand via ClawHub, which means smaller core installs and faster upgrades going forward.

Check your installed skills and look for any that may need updating:

openclaw skills list

For skills with available updates:

openclaw skills update --all

Note: Verify these exact commands against the official ClawHub skill documentation — the CLI syntax reflects what was available at v2026.5.2. Earlier or later versions may differ.

Step 5: Verify Your Gateway and Connectors

The gateway performance improvements in this release changed how tools are cached and how sessions are initialized. If you run OpenClaw as a server (gateway mode), restart the gateway after upgrading:

openclaw gateway restart

Then confirm your messaging connectors — particularly Discord if you use it — are reconnecting cleanly. The restart-safe improvements mean Discord should survive gateway restarts without dropping its connection state.

What to Expect

After a clean upgrade and openclaw doctor --fix, you should see:

  • Faster gateway startup (the cached tool manifest is loaded rather than re-fetched)
  • Grok 4.3 available for xAI queries with 1M token context
  • Sturdier plugin installs that don’t fall over on intermittent network issues
  • Discord sessions that survive gateway restarts

The “less drama, more uptime” tagline is earned here. This is a maintenance and stability release with a meaningful model upgrade bundled in — exactly what a v2026.5.2 patch version should be.
