plugins.installs removed from authored config files.- New CLI command:
openclaw plugins registry.
⚡ Key Improvements
OpenTelemetry (Full-Stack Observability)
- Traces for: model calls, token usage, tool loops, harness runs, exec processes, outbound delivery, context assembly, memory pressure.
- Bounded low-cardinality attributes — no session IDs or prompt content leaked.
- W3C traceparent propagation for distributed tracing.
- Bundled
diagnostics-prometheus plugin for metrics export.
Browser Automation Upgrades
- Safer tab URL handling and iframe-aware role snapshots.
- CDP readiness tuning and headless one-shot launch.
- Deep
browser doctor --deep probing for diagnostics.
- Raspberry Pi support added.
🎨 Control UI & Install Hardening
Control UI
- PWA install support for desktop/mobile.
- Web Push notifications.
- Crestodian first-run repair and TUI setup.
- Context mode selector in UI.

🔄 Migration Guide
| Step | Action | Risk |
|---|
| 1 | Backup ~/.openclaw/config.yaml | Low |
| 2 | Run openclaw update or reinstall via install script | Low |
| 3 | Remove plugins.installs from config (now auto-managed) | Low |
| 4 | Verify TTS providers in openclaw providers list | Low |
| 5 | Enable OpenTelemetry via diagnostics-prometheus plugin if monitoring | Medium |
| 6 | Test browser automation with browser doctor --deep | Low |
Note TTS provider configs may need re-authorization after update.
👥 Community Response
"The TTS overhaul finally makes OpenClaw usable for long-form reading. ElevenLabs v3 integration is seamless."
"OpenTelemetry is a game-changer for teams running OpenClaw in production. We can finally trace token costs per user session."
"Four beta builds in 24 hours was chaotic, but the stable release is rock solid."
Sentiment: Positive Enterprise-ready
⚠️ Known Issues & Pain Points
- Rapid beta churn: Four prerelease builds in one day caused confusion about which beta to test. Some users skipped to stable.
- TTS re-auth: Existing TTS provider tokens may require re-authentication after the overhaul.
- Plugin registry cache: Users with custom plugin registries need to run
openclaw plugins registry --refresh manually.
- Telemetry opt-in: OpenTelemetry is opt-in via plugin; some users expected it to be on by default for transparency.
- Raspberry Pi limitations: Browser automation on Pi requires headless mode and has reduced concurrency.
🎯 Competitive Position
| Capability | OpenClaw | Claude Code | Cursor |
|---|
| Voice / TTS | ✅ 7 providers | ❌ None | ❌ None |
| Observability | ✅ OpenTelemetry | ⚠️ Basic | ⚠️ Basic |
| Browser automation | ✅ Full CDP | ✅ Full CDP | ❌ Limited |
| Plugin registry | ✅ Cold persisted | ❌ N/A | ❌ N/A |
| PWA UI | ✅ Yes | ❌ Terminal | ✅ Desktop |
OpenClaw is carving out a unique position as the voice-native, observable, plugin-extensible agent platform.
🗺️ Roadmap Implications
- Voice-first: With 7 TTS providers and chat-scoped controls, OpenClaw is signaling voice as a first-class modality. Expect deeper STT integration next.
- Enterprise telemetry: Full OpenTelemetry support positions OpenClaw for SOC2 and enterprise procurement. Cost attribution per session is a key differentiator.
- Platform breadth: Raspberry Pi support and Docker hardening suggest edge and embedded deployment targets.
- Plugin ecosystem: Cold registry is foundational for a marketplace model. Watch for third-party plugin publishing.
📋 Summary
OpenClaw v2026.4.25 is a major stable release that vaults the platform into voice-native, enterprise-observable territory.
Key Takeaways:
- TTS overhaul with 7 providers makes it the most voice-capable agent CLI.
- OpenTelemetry integration is production-grade and privacy-respecting.
- Plugin registry refactor enables future marketplace growth.
- Install hardening across all platforms signals enterprise readiness.
