OpenClaw v2026.5.20-beta.1 Release Summary

OpenClaw v2026.5.20-beta.1 brings a significant array of enhancements focused on communication channel depth, enterprise-grade governance, and the stability of complex agent orchestrations. This release is particularly noteworthy for its expansion of Discord voice capabilities and the introduction of a formal policy system to ensure workspace conformance.

Key Changes

Discord Voice & Realtime Enhancements

OpenClaw has significantly expanded its Discord integration to support more dynamic voice interactions:

• Voice User Following: Voice sessions can now follow configured Discord users into voice channels. This includes multi-user handoff, bounded reconciliation for large user sets, and preservation of DAVE recovery state (#84264).
• Realtime Bootstrap Context: Discord voice sessions now include bounded profile context (IDENTITY.md, USER.md, and SOUL.md) in realtime voice session instructions by default, providing agents with immediate grounding in their persona and user context (#84499).

Enterprise Policy & Conformance

A new bundled Policy plugin has been introduced to provide operators with a way to express and audit workspace requirements (#80407). This system allows for:

• Channel Conformance: Defining rules (e.g., denying specific providers like Telegram) in a policy.jsonc file.
• Auditable Proof: The policy check --json command produces an attestation hash binding the policy, evidence, and findings, creating a durable audit trail.
• Automated Repair: Through doctor --fix, operators can opt-in to workspace repairs that automatically disable non-conforming channel settings.

Agent Orchestration & Stability

Several deep architectural fixes improve the reliability of subagents and complex runs:

• Subagent Recovery: Fixed a critical issue where subagent completion announcements could fail to surface to the requester if the original run was stale. The system now forces a message-tool handoff to ensure results are delivered (#83700).
• Subagent Target Constraints: Wildcard allowlists (allowAgents: ["*"]) are now constrained to configured agents only, preventing the accidental creation of arbitrary agent state roots on disk (#84357).
• LLM Timeout Flexibility: The system now honors explicit models.providers.<id>.timeoutSeconds values for cloud providers, removing the implicit 120s ceiling that previously caused aborts during long first-token waits for models like Anthropic Opus (#83979).

Provider & Integration Updates

• xAI OAuth: Added device-code OAuth login, enabling remote and headless setups to authorize xAI without requiring a localhost browser callback (#84005).
• OpenRouter Routing: Now honors provider-level params.provider routing policies (#84499).
• Anthropic Routing: Fixed routing for shorthand model references (e.g., anthropic/opus-4.7) to ensure they use the Claude CLI runtime when configured (#84374).

Impact

Performance & Liveness

• Event Loop Optimization: High-frequency diagnostic events are now processed in chunks (max 100 per turn), preventing diagnostic bursts from monopolizing the gateway event loop and causing liveness stalls (#82937).
• Cron Isolation: Scheduled work targeting the main session now runs on a dedicated cron-owned wake lane. This prevents background automation from blocking interactive human web-chat turns (#82767).

Data Integrity & Security

• Cron Store Preservation: Fixed a P0 data-loss bug where legacy plain-array jobs.json stores were treated as empty and clobbered during upgrades (#84433).
• Security Hardening: Hardened the creation of update restart scripts by using exclusive creation in generated temporary subdirectories (#84088) and added a final allowlist check for rebuilt system.run shell arguments (#84090).

User Experience

• Codex Auth Clarity: The /codex account command now correctly respects explicit authentication order over the lastGood heuristic, ensuring the displayed active profile matches the runtime selection (#84412).
• Image Sanitization: Browser screenshots and labeled snapshots now honor the global agents.defaults.imageMaxDimensionPx limit (#84595).

Upgrade Guide

Breaking Changes & Migration

• Subagent Wildcards: If you previously relied on allowAgents: ["*"] to target unconfigured agent IDs, you must now list those IDs explicitly in the allowlist to maintain that behavior.
• Mattermost Routing: Mattermost events with unresolved channel types will now fail closed (be ignored) rather than defaulting to regular channel traffic. Ensure your Mattermost channel configurations are complete.
