OpenClaw Releases v2026.5.2 with Plugin Migration from npm to ClawHub, 200+ Bug Fixes

According to Beating, open-source personal AI assistant OpenClaw released v2026.5.2 on May 3, a major engineering maintenance update. The core change involves migrating the plugin system from npm to the self-built distribution platform ClawHub. The update includes over 200 bug fixes and introduces the ClawPack packaging format with versioned artifact metadata. npm remains the default for now, with ClawHub enabled only when explicitly specified with the clawhub: prefix during the transition period.

A notable bug fix addressed a critical heartbeat scheduler issue: the scheduler previously failed to handle process exit event feedback loops correctly, causing heartbeats configured for every 30 minutes to trigger every 10 seconds instead, with event loop latency peaks exceeding 6 seconds. This rendered Control UI and TUI unresponsive. The new version introduces centralized cooldown mechanisms and per-agent rate limiting, capping unexpected feedback loops to a maximum of 5 occurrences per 60 seconds.
