OpenClaw 3.22 introduces major plugin system overhaul

OpenClaw has launched its significant 3.22 update, marking a complete overhaul of its plugin system and introducing the new GPT-5.4 model. This version, released on March 22, 2026, features a new plugin SDK that replaces the old extension API, necessitating all existing third-party plugins to migrate to the new system. The update also emphasizes security enhancements for Windows users, addressing multiple vulnerabilities and reinforcing the execution environment, which is crucial for maintaining user trust in AI automation.

Additionally, the update has shifted the default source for plugin installations to ClawHub, OpenClaw's official plugin marketplace, ensuring a higher quality of available plugins. This change aims to streamline the agent workflow and improve the overall ecosystem by reducing reliance on the more generic npm package manager. With these updates, OpenClaw not only enhances its developer tooling but also sets a new standard for plugin quality and security, making it a more robust platform for developers and users alike.
