OpenClaw v2026.5.27 and v2026.5.28: What’s New and How to Use It

OpenClaw shipped two significant releases this week — v2026.5.27 (stable security hardening) and v2026.5.28 (stable feature expansion with beta previews) — bringing GitHub Copilot as a first-class agent runtime, full Claude Opus 4.8 coverage, ClawHub plugin trust surfaces, and a wave of cross-channel identity fixes. Here’s what changed, why it matters, and how to make use of the new capabilities.

What’s New in v2026.5.27

Version 2026.5.27 focused heavily on tightening security and runtime boundaries. A few notable changes:

  • Group prompt injection prevention: Text from group chats (Telegram, Discord, etc.) is now kept out of the system prompt, blocking a class of prompt injection vectors where malicious group messages could hijack agent behavior.
  • DNS trick vectors closed: Repeated-dot hostnames (e.g., host..example.com) are now normalized and blocked at the network layer.
  • Side-effecting command wrappers blocked: Unsafe Node runtime environment overrides are rejected before execution.
  • Tailscale exposure without auth rejected: No-auth Tailscale setups can no longer expose the gateway inadvertently.
  • Node/device-role approvals now admin-gated: Privilege escalation for device roles requires explicit admin authority, reducing the risk of accidental over-permissioning.

This release is a recommended upgrade for anyone running OpenClaw as a personal gateway or in a team setting — the security changes are meaningful and mostly invisible to end users.

What’s New in v2026.5.28

Version 2026.5.28 is the bigger news. It introduces two headline features alongside a long tail of reliability improvements.

GitHub Copilot as an Agent Runtime

OpenClaw now integrates GitHub Copilot as a full agent runtime — not just as a code completion backend, but as a delegated workflow engine for Codex Supervisor tasks. The setup flow supports both device login and native provider modes. According to the official docs at docs.openclaw.ai/providers/github-copilot, you can activate Copilot as an agent runtime through your provider configuration. Consult the official documentation for exact CLI commands and configuration keys, as these change across releases.

Why does this matter? For teams already invested in GitHub’s ecosystem, this creates a bridge between OpenClaw’s multi-agent orchestration and Copilot’s coding workflows — letting you delegate structured subtasks to Copilot while OpenClaw handles routing, memory, and approval flows.

Claude Opus 4.8 Support

Claude Opus 4.8 is now fully supported as a provider model. Key capabilities surfaced in the OpenClaw provider docs (docs.openclaw.ai/providers/anthropic) include:

  • 1M token context window — suitable for entire codebases, large documents, or long agent sessions
  • Adaptive thinking via /think commands — thinking is off by default for latency, togglable per-session
  • Extended thinking mode for deep reasoning tasks

To use Opus 4.8, select it as your model in your OpenClaw provider configuration. The exact model identifier and configuration path should be verified against the official provider docs, as model names follow Anthropic’s versioning scheme.

ClawHub Plugin Verification and Trust Surfaces

ClawHub — OpenClaw’s plugin marketplace — now displays skill verification badges and trust surfaces. This makes it visually clear which plugins have been verified vs. community-contributed, and introduces display names for better discoverability.

For plugin consumers: look for the verification badge before installing third-party skills. For skill authors: the verification and trust surface features are now part of the ClawHub submission flow.

Subagent Workspace Separation

A particularly welcome fix: subagents now properly maintain their cwd and workspace separation. Previously, shared runtime state could bleed between parent and subagent contexts. Hook context now stays prompt-local, session locks release on timeout abort, and Codex app-server/helper failures no longer tear down shared runtime state.

Channel Delivery and Identity Improvements

Both releases bring reliability work across the full channel surface:

  • Matrix, iMessage, Slack, Discord, WhatsApp, Telegram, Teams — safer outbound plugin hook handling and more reliable channel identity resolution
  • iOS Pro UI — updated session picker with better state preservation
  • Gateway chat transport — improved onboarding flow

How to Upgrade

Upgrade via npm (check the official OpenClaw releases page for the exact version tag and any migration notes specific to your environment):

# Refer to official docs for exact upgrade command
# Check: https://github.com/openclaw/openclaw/releases

⚠️ Note: Always check the official release notes before upgrading, particularly for any breaking changes to provider configuration or plugin APIs.

Other Additions Worth Noting

  • MiniMax streaming music — audio generation with streaming output
  • Encrypted PDF extraction — documents behind passwords can now be processed by ClawPDF
  • Fal Krea images and NVIDIA model support — expanded provider surface for image and inference workloads
  • Voice catalogs — updated voice selection for TTS workflows
  • iMessage reaction approvals — approve or deny agent actions via iMessage reactions
