• Output Format: Pure Markdown, no JSON/code blocks.

  • Current Version: v2026.4.8.

  • Key Fixes:

    • Telegram/multi-channel import via sidecars (npm builds).
    • Plugin metadata alignment.
    • OpenAI: Compact payloads/planTool, /exec host-aware reporting.
    • Slack: HTTP(S) proxy/NO_PROXY for Socket Mode, downloadFile token fix.
    • Optimization: Model override fast-path, CI isolation, TLS port fix.

  • Context (Ling Xiao's setup): Native deployment (no Docker), PM2, systemd, Nginx + Cloudflare Tunnel.

  • Persona: Direct, professional, no fluff.

  • Headline: Needs to be strong. "OpenClaw v2026.4.8: Enhancing Architectural Stability and Agent Execution Efficiency."

  • Introduction: The update isn't just a patch; it's a surgical improvement for stability and agent efficiency. It addresses friction in native deployments.

  • Impact Analysis (The "meat"):

    • Channel Stability: The sidecar fix for npm builds is crucial. For our native (non-Docker) setup, this solves path/import issues for Telegram and other channels.
    • Agent Performance: OpenAI improvements (compact payloads/planTool) = lower token cost + faster response. /exec reporting is more accurate now.
    • Connectivity/Slack: The proxy support for Slack Socket Mode is vital for our Cloudflare Tunnel/Nginx setup.
    • Plugin Integrity: Metadata alignment prevents version mismatch errors.

  • Upgrade Suggestions:

    • Use openclaw-updater.
    • Check Slack proxy if using Socket Mode.
    • Verify plugin metadata post-update.

  • Tone Check: Avoid "I think" or "It seems." Use "This update addresses," "This is critical for," "We should."

  • Vocabulary: Use terms like "architectural friction," "surgical precision," "native deployment," "payload optimization," "host-aware reporting."

  • Title: OpenClaw v2026.4.8: A Leap in Architectural Stability and Agent Efficiency

  • Intro: The v2026.4.8 release is more than a routine patch; it is a targeted refinement of OpenClaw’s core execution logic and deployment stability. This update specifically addresses architectural friction points that impact high
