OpenClaw 2026.4.2 Is Out
OpenClaw 2026.4.2 ships with three changes that matter for B2B sales automation: restored Task Flow orchestration, hardened exec security defaults, and new WhatsApp reaction guidance.
B2B SDR Agent Template v3.5.0 is fully compatible — no breaking changes for SDR deployments.
What's New
1. Task Flow — Background Orchestration Restored
The core Task Flow substrate is back with managed-vs-mirrored sync modes, durable flow state tracking, and openclaw flows inspection primitives.
For B2B SDR agents, this unlocks:
- Background lead nurture sequences that persist across sessions
- Multi-step follow-up workflows that survive gateway restarts
- Parallel prospect tracking — manage 50+ active leads without context overflow
Task Flow is available automatically in 4.2. No configuration required.
2. Exec Security — Now Default
OpenClaw 2026.4.2 makes security=full with ask=off the default exec mode. Previously, this required explicit configuration in exec-approvals.json (added as a fix in b2b-sdr-template v3.3.1 for 4.1 compatibility).
The template keeps the explicit config for forward-compatibility, but new installs on 4.2 will work correctly even without it.
3. WhatsApp reactionLevel
OpenClaw 2026.4.2 adds reactionLevel guidance for agent reactions to customer messages. Three levels are available:
| Level | Behavior | B2B SDR Recommendation |
|---|---|---|
"none" |
No reactions | Default — safest for new accounts |
"selective" |
React to key messages | ✅ Confirmations, 👀 Inquiries |
"active" |
React to all messages | High engagement, use carefully |
For B2B SDR, "selective" strikes the right balance — it signals responsiveness on quotes and inquiries without over-automating.
Breaking Changes (Not SDR-Relevant)
Two breaking changes in 4.2 do not affect standard B2B SDR deployments:
- xAI plugin:
tools.web.x_search.*→plugins.entries.xai.config.xSearch.*— only if you use xAI web search - Firecrawl plugin:
tools.web.fetch.firecrawl.*→plugins.entries.firecrawl.config.webFetch.*— only if you use Firecrawl
Run openclaw doctor --fix to migrate either config automatically.
