OpenClaw 2026.6.5 Stable Release: QQBot Thinking Fix, Parallel Search, MCP Coercion

OpenClaw 2026.6.5 shipped June 9, 2026 as the latest stable release, landing a mix of reliability, security, and new bundled capabilities.

What changed

QQBot reasoning scaffolding stripped. Model <thinking> blocks and other reasoning metadata are now removed before delivery to QQBot channels, preventing raw assistant internal content from leaking into replies. Previously, unprocessed model output could expose scaffolding text directly to end users.

MCP tool result coercion. MCP tools returning richer content types — resource_link, resource, audio, malformed images, and future non-text/image blocks — are now coerced at the materialize boundary. This fixes a class of Anthropic 400 errors and prevents “poisoned” session history after tools return richer-than-expected content.

Anthropic extended-thinking recovery. Sessions using extended thinking now recover cleanly after prompt-cache expiry or Gateway restart. Stream start events now wait for message_start, letting pre-generation signature errors trigger the existing recovery retry rather than silently failing.

Parallel bundled as web_search provider. Parallel joins the built-in search providers with PARALLEL_API_KEY discovery, guarded endpoint handling, cache-safe session IDs, onboarding picker support, and documentation.

Google Vertex improvements. Static catalog rows and runtime model resolution are restored for Vertex ADC users. Single-provider cooldown recovery and memory adapter status checks are more reliable.

Matrix voice and threads. Voice notes now run a preflight check before mention gating. Thread reads and replies are preserved through Matrix relations pagination, with QA coverage for both voice and thread flows.

Auth moved to SQLite. Auth profiles now persist in SQLite rather than JSON, making them more durable. Official npm plugin install records keep their trusted pins, and prerelease fallback integrity checks avoid carrying stale state forward.

macOS node mode connection stability. The macOS companion app no longer silently reconnects away from a healthy direct Gateway session, reducing unexpected session churn.

ClawHub GitHub skill installs. Skills hosted in GitHub repos can now be installed through ClawHub using the resolved install API — downloads the pinned commit, keeps install-policy checks, and reports telemetry after success.

Stricter agent/tool/provider loops. Loop guards are tightened around MCP lease timestamps, prompt-cache tool names, local tool catalogs, unreadable dynamic tools, owner-only HTTP tools, and provider catalog metadata — reducing hidden retries and unsafe exposure.

Mobile polish. Android provider/model screens surface expiring, unavailable, unresolved, and attention states more clearly. Android adds theme mode selection. iOS settings and Talk tabs keep diagnostics, gateway rows, and fallback controls reachable.
