OpenClaw v2026.5.28: Agent Runtime Stability and Channel Delivery Improvements

OpenClaw just shipped v2026.5.28, and it's all about making agent runtimes more resilient. The changelog is dense, but the core message is simple: fewer crashes, cleaner state, and safer messaging. For anyone building multi-agent systems, this update fixes some gnarly edge cases.

What Changed

Agent and Codex runtime recovery got a major overhaul. Subagents now keep their cwd and workspace strictly separated. That means no more accidental cross-agent file contamination. Hook context also stays prompt-local — a subtle but critical fix if you're chaining complex workflows.

Session locks now release properly on timeout abort. Before, they'd sometimes hang around, blocking subsequent runs. Live OpenClaw locks survive cleanup, so ongoing agents don't get killed when another session times out. And stale restart continuations? Gone. The runtime explicitly avoids them now.

Codex app-server and helper failures won't tear down shared runtime state anymore. That's a big one for reliability. If one component hiccups, it doesn't bring the whole house down.

Channel delivery and session identity got safer too — across outbound plugin hooks, Matrix room IDs, iMessage reactions, and more. The team tightened up parsing and validation, so malformed messages don't break delivery.

Why It Matters

For developers running OpenClaw agents in production, these changes reduce silent failures. Subagent isolation is table stakes for security and correctness. The session lock fix prevents resource leaks — something that can cause cascading outages in high-throughput environments.

But the real win is the Codex runtime recovery. When an app-server crashes, you want your agent to keep going, not restart from scratch. This update makes that possible.

In practice, expect fewer unexplained agent deaths and more predictable message delivery. It's the kind of release that doesn't add flashy features but makes everything else work better.
