OpenClaw 2026.3.23: The Great Browser Migration, ClawHub Supremacy, and GPT-5.4 Integration

The OpenClaw 2026.3.23 release is here, and it marks a turning point for the platform's architectural stability. Following the v2026.3.22 major SDK update, this release focuses on standardizing the foundational layers of agent interaction—specifically how plugins are discovered and how browsers are controlled.

While this update brings much-needed clarity, it is also a "Migration Release." If you use Chrome browser automation, you will most likely experience breakages upon upgrading. Don't worry, though; we have the fix.

The Great Browser Migration (Breaking Change)

The most significant change in OpenClaw 2026.3.23 is the complete removal of the Legacy Chrome extension relay path. This includes the removal of bundled extension assets, the driver: "extension" parameter, and browser.relayBindHost.

For years, the extension relay was the primary way for OpenClaw to "speak" to your browser. However, it was prone to latency and session hijacking. This release officially transitions all host-local browser automation to the more stable existing-session / user mode.

How to Fix Your Setup

If your browser automation stops working after the update, you don't need to rebuild your config from scratch. OpenClaw now includes a migration utility in its diagnostics tool. Simply run:

openclaw doctor --fix

This will automatically migrate your local configurations to the new mode. Note that Docker, headless, sandboxed, and remote browser flows are unaffected by this change. For more on managing browser sessions, review our Security Best Practices.

ClawHub: The New Default for Plugins

In a move to further decentralize and secure the ecosystem, ClawHub is now the default installation source for plugins.

Previously, OpenClaw prioritized npm, which often led to confusion between general-purpose JavaScript libraries and specialized AI agent plugins. Starting with v2026.3.23, when you run openclaw plugins install, the system will systematically prioritize ClawHub for npm-safe package names, using npm only as a fallback.

This ensures that you are getting the community-vetted, security-hardened versions of tools specifically designed for the Plugin SDK introduced in v2026.3.22.

Standardizing Intelligence: GPT-5.4 & Image Generation

The "standard" OpenClaw setup has received two major consistency updates:

GPT-5.4 everywhere: The default OpenAI model for all new setups is now openai/gpt-5.4. Codex remains on openai-codex/gpt-5.4. These defaults are now centralized in a shared core module, ensuring that chat, TTS, and embeddings all use the most efficient model paths by default.
Native Image Generation: The image creation and editing path has been standardized on the core image_generate tool. This replaces the old method of wiring image generation through bulky "skill wrappers." A single configuration line now handles what previously took an entire block of skill code.

CLI Hooks and Tooling

Maintenance and visibility also received some love in this release:

CLI Hook Routing: Installation and update hooks are now routed through openclaw plugins. This makes it much easier to track which plugin is triggering which post-install action.
Hook Visibility: The openclaw hooks command now focuses entirely on hook visibility and per-hook controls, allowing admins to toggle specific automated actions without disabling the entire plugin system.
macOS Chrome Fixes: This update resolves frustrating user-profile timeouts and repeated consent "churn" on macOS Chrome attach flows. The browser now intelligently waits for existing-session tabs to become usable before attempting to attach the agent.

Why the "Correction" Releases? (v2026.3.23-1 and -2)

If you noticed 2026.3.23-1 or 2026.3.23-2 in your logs, don't panic. These were immediate hotfixes for a few "newer OpenClaw" warnings that were appearing incorrectly in some environments. The core base version remains 2026.3.23, but we recommend always pulling the latest dash-release for maximum stability.

OpenClaw 2026.3.23 is a foundational update that sets the stage for the next generation of autonomous browser agents. You can find the full changelog and assets on the official GitHub repository.
