OpenClaw v2026.5.12-beta.3 Release Summary

Key Changes

This release focuses on expanding the capabilities of the Plugin SDK, refining the orchestration of subagents, and hardening the stability of various channel integrations. A major highlight is the introduction of new workflow seams in the Plugin SDK, allowing developers to create more complex, host-mediated agent behaviors.

Plugin SDK & Workflow Enhancements

• New Workflow Seams: Plugins can now register typed session actions, send session-bound attachments through host-owned delivery, and schedule future session turns via the existing cron-compatible scheduler.
• Finalize Retry Support: Plugins can now request bounded retries before a reply is finalized, enabling more robust quality control for agent outputs.
• Priority Queuing: Queued next-turn injections now support priority levels, allowing critical updates to be processed ahead of standard turns.

Agent & Session Orchestration

• Subagent Session Management: Subagent sessions are now visually nested under their parent sessions in the Control UI using a └– prefix, making complex agent hierarchies easier to navigate.
• Exec Reference Preservation: Background exec process references are now preserved across session compaction, ensuring that long-running tasks are not orphaned when the context window is refreshed.
• Subagent Heartbeat Optimization: Redundant heartbeat wake-ups for subagent session completions have been skipped to prevent spurious LLM invocations on parent sessions.

Channel & Provider Updates

• Slack Integration:
  • Added replyBroadcast support for thread replies, allowing agents to post to both a thread and the parent channel.
  • Implemented allowBots: "mentions" mode to prevent infinite reply loops in multi-agent environments.
  • Improved file attachment handling in DMs by fetching fresh download URLs via files.info.
• Telegram Integration:
  • Fixed thinking status defaults in the /status and /think menus to correctly reflect model defaults and session overrides.
  • Added support for forcing video media to be sent as documents to avoid compression.
• iMessage Integration: Added support for tapback reaction forwarding as inbound agent events.
• Model Providers:
  • llama.cpp: Now supports opportunistic discovery of the actual loaded runtime context (n_ctx) via the /props endpoint, providing more accurate token usage metrics.
  • OpenAI-compatible: Improved streaming transport to drain split frames, preventing stalled sessions during high-latency responses.

Infrastructure & Tooling

• pnpm 11 Upgrade: The workspace has been upgraded to pnpm 11, aligning project settings and build allowlists within pnpm-workspace.yaml.
• Memory Management: Introduced a bounded compaction step for MEMORY.md during dreaming promotions to prevent unbounded file growth and potential gateway freezes.
• Cron Enhancements: Added a direct cron.get path (via CLI and Gateway RPC) for inspecting single stored cron jobs by ID.

Impact

Fixed Issues

• Memory Leak/Growth: Fixed a critical bug where MEMORY.md could grow unboundedly, leading to bootstrap overflow and gateway freezes (#73691).
• Subagent Orphanage: Resolved an issue where subagents lost references to running exec processes after session compaction (#79284).
• Gateway Stability: Fixed a race condition in gateway inflight deduplication for send and poll requests (#68341).
• TUI Responsiveness: Fixed a hang where the TUI became unresponsive to Ctrl+C/SIGINT after a gateway disconnect (#75379).
• Security: Redacted sensitive WhatsApp/libsignal session material from raw gateway terminal logs to prevent secret exposure (#76306).

Performance Improvements

• Streaming Efficiency: Gateway streaming fan-out now shares serialized event envelopes across recipients, reducing redundant JSON serialization on the hot path (#80299).
• Session Resolution: Scoped sessions.resolve calls now only load the requested agent's store rather than loading all agent stores simultaneously, significantly reducing memory pressure (#51264).

Upgrade Guide

Breaking Changes & Migration

• pnpm 11: Users performing source installs must upgrade to pnpm 11. The bootstrap process has been updated to handle the new pnpm-workspace.yaml configuration.
• Memory-Wiki Scopes: The wiki.ingest method now requires operator.admin scope, and wiki.obsidian.search now requires operator.write scope. Users with restricted gateway tokens may need to elevate their permissions to continue using these features.
