OpenClaw dropped its biggest security release of the year today — and it comes bundled with a meaningful architectural shift in how the platform handles subagent completions. Version 2026.2.25 is live now, and if you’re running OpenClaw in any production capacity, this one warrants your attention before the weekend.

The Headline: 30+ Security Fixes in a Single Release

That’s not a typo. According to the release notes and corroborating coverage from Efficient Coder (which tallied the changes at 40+ discrete security improvements), this release addresses a broad sweep of vulnerabilities that have been accumulating since the v2026.2.24 cycle. The categories span:

  • Reactions auth hardening — Permissions checks on emoji reactions tightened; previously, certain token configurations could allow unauthorized reaction writes
  • Pairing isolation fixes — Cross-node pairing leakage scenarios addressed in the device pairing flow
  • Exec escape patches — Shell execution contexts now enforce stricter sandboxing, reducing command injection surface
  • Webhook guards — Inbound webhook validation strengthened against replay and spoofing attacks

For teams running OpenClaw with external integrations — particularly webhook-heavy setups or multi-node pairings — these are the patches you’ve been waiting for.

Subagent Delivery: From Heuristics to a State Machine

The more interesting architectural change is the subagent completion announce dispatch refactor. Previously, how a completed subagent’s results got routed back to the requester session involved a degree of heuristic fallback logic that could behave inconsistently under load or unusual session configurations.

v2026.2.25 replaces that with an explicit queue → direct → fallback state machine:

  1. Queue path — If the requester session has an active message queue, completed subagent results are dispatched there first
  2. Direct path — If no queue is active but the session is live, results deliver directly via the session channel
  3. Fallback path — For sessions that have closed or become unreachable, results are persisted and surfaced on next reconnect

This is a meaningful reliability improvement for long-running pipeline architectures where subagents may complete after their parent session has cycled. If you’re building agentic pipelines with sub-agents that run for minutes or longer, this change makes completion delivery substantially more predictable.

Breaking Change: heartbeat.directPolicy Reverts to allow

This is the one to flag in your changelogs. A prior release had changed heartbeat.directPolicy default to deny as a security-hardening measure. v2026.2.25 reverts this default back to allow.

What this means in practice: If your deployment relies on the deny default behavior — specifically, if you’ve built access controls that assume heartbeat direct delivery is blocked unless explicitly permitted — you’ll need to explicitly set heartbeat.directPolicy: deny in your config to preserve that behavior after upgrade.

Teams that never touched this setting and were confused by blocked heartbeats in recent builds will find things “just work” again post-upgrade. The release notes suggest the deny default experiment revealed too many legitimate use cases that relied on direct heartbeat access.

Android: Chat Streaming and Markdown Rendering

Beyond security and architecture, the Android client gets two quality-of-life improvements:

  • Chat streaming — Responses now stream incrementally on Android rather than arriving as a single block, matching the behavior users expect from web and iOS
  • Markdown rendering — Code blocks, headers, and formatted lists now render correctly in the Android chat UI

These were long-standing gap items for Android users and represent genuine usability improvements for mobile-first workflows.

Dependency Bumps Worth Noting

The release also updates:

  • Bedrock SDK to 3.998.0 (AWS users maintaining Bedrock integrations should validate their client configs)
  • TypeScript native preview to 7.0.0-dev.20260225 — this is a development dependency for contributors, not a runtime change for most deployments

Should You Upgrade Now?

For most users: yes, and soon. The security fixes alone justify the upgrade cycle. The heartbeat policy change is the only behavioral delta that requires configuration review, and it only affects deployments that deliberately set directPolicy: deny.

If you’re running a large production instance, the standard guidance applies: test on staging first, validate your heartbeat configs, then roll forward. But the subagent delivery improvements and security hardening make this a high-priority upgrade rather than a routine one.
