OpenClaw v2026.5.2, released on May 2, 2026, is the first stable cut of the 2026.5 line. It focuses on performance across the gateway hot path, externalizes the plugin lifecycle around ClawPack metadata, and rolls forward to a new xAI default. Upstream summarizes the release as covering "External plugin installation, update, doctor repair, dependency reporting, and artifact metadata" alongside leaner "Gateway and agent hot paths" for startup and session operations.
Plugin Install Goes External
External plugin installation now covers diagnostics, onboarding, doctor repair, and channel setup with first-class ClawPack manifest support. ClawHub artifact resolution understands versioned package metadata, git: specs install plugins straight from a Git URL, and a beta-channel fallback keeps installs working when no beta release exists. openclaw plugins list --json now exposes dependency state so operators can see what each plugin is actually pulling in.
Gateway Hot-Path Performance
The gateway skips auth-profile overlays during startup so it reaches readiness faster, and tool descriptor caching cuts repeated prompt-time plugin loading. Filesystem checks gain fast-path POSIX containment, and hot transcript reads move to async bounded I/O so a busy session no longer blocks the event loop. The release lands 268 fixes spanning transcript locking, memory rebuilds, and provider edge cases.
Channel Resilience
Channel improvements target "Sessions, Cron, long-running Gateway WebSockets, grouped-message width, slash-command feedback, iOS PWA bounds, selection contrast, and Talk diagnostics." WhatsApp gains explicit Newsletter and Channel targeting, Discord persists buttons and selects across gateway restarts, Slack tightens thread tracking and the App Home tab, and Telegram picks up forum topic command support.
Provider Updates
The xAI default moves to Grok 4.3. OpenAI Realtime gains TTS and streaming compatibility, DeepSeek normalizes reasoning metadata for replay, and LM Studio surfaces local-model reasoning. Voice Call now opens with a per-call session scope so each call starts with fresh memory, and macOS Talk Mode downmixes multi-channel microphone buffers — useful for users with pro audio interfaces.
Rollout
Managed instances on OpenClaw Launch pick up v2026.5.2 as part of the regular image refresh, so the new defaults and gateway speedups land without a manual upgrade.
