OpenClaw v2026.4.11: Active Memory, Teams & WhatsApp Resilience

OpenClaw shipped two major stable releases in two days — v2026.4.10 (Apr 11) and v2026.4.11 (Apr 12) — and the combined changelog is one of the most impactful for B2B sales teams since the product launched. Two headline features stand out: an opt-in Active Memory sub-agent that gives your AI SDR a real-time memory refresh before every reply, and full Microsoft Teams integration with reactions, media, and OAuth. Below is the no-fluff breakdown every B2B export team should read before upgrading.

What Changed — B2B SDR Edition

1. Active Memory Plugin: Your Agent Never Forgets Again

The biggest architectural addition in v2026.4.10 is the Active Memory plugin — a dedicated memory sub-agent that fires before the main reply. Instead of relying solely on MemOS snapshots loaded at session start, Active Memory queries your conversation history and knowledge base in real time, right before the agent speaks.

For a B2B SDR agent handling dozens of simultaneous WhatsApp threads, this is a game-changer:

• Configurable modes: message (last N messages), recent (recent turns), or full (complete context). Start with recent for SDR workloads.
• Live inspection: Run /verbose to see exactly what memory the agent pulled before it replied.
• Opt-in: Enable via plugins.slots.contextEngine in your OpenClaw config. Docs: docs.openclaw.ai/concepts/active-memory

Key fact: In production SDR deployments, agents that surface customer history (BANT scores, past objections, quoted prices) in every reply see 2–3× higher follow-up response rates compared to stateless agents.

With Active Memory, your agent automatically recalls that Ahmed from Dubai was quoted $4,200 FOB for 500 units two weeks ago — without you needing to remind it.

PulseAgent note: On PulseAgent managed plans, Active Memory is pre-configured with mode: recent out of the box — no plugin wiring needed.

2. Microsoft Teams: Now a First-Class B2B Channel

v2026.4.10 and v2026.4.11 together deliver a complete Microsoft Teams integration overhaul:

For B2B export companies selling to enterprise buyers in Western markets, Teams is increasingly the real communication channel — not email. Your AI SDR can now react with ✅ to acknowledge receipt, pin key quotes to thread history, and download shared RFQ documents automatically.

How to enable: Set up channels.teams in your OpenClaw config with delegated OAuth credentials. The setup wizard now handles the full auth flow.

3. WhatsApp Reconnect Resilience (Finally)

v2026.4.10 fixed a long-standing issue (#30806, #46299): when a WhatsApp connection dropped and reconnected, inbound replies, media, composing indicators, and queued outbound deliveries could be silently lost.

For 24/7 AI SDR operation, a midnight reconnect event no longer means lost leads at 3am. The fix preserves the full delivery queue across reconnect gaps.

v2026.4.11 adds: WhatsApp now correctly honors the configured default account when the active listener helper is used without an explicit account ID — preventing a subtle mis-routing issue where replies from a secondary account were routed to the wrong thread.

4. Gateway Thread Routing: Multi-Channel Threads Stay Intact

A comprehensive fix in v2026.4.10 ensures that subagent messages, cron announcements, stream-relay replies, and session-fallback messages all land in their originating thread — not a random top-level channel. This affects Slack, Telegram, Mattermost, Matrix, and ACP targets.

For multi-channel SDR pipelines (WhatsApp for initial contact → Telegram for follow-up → Email for formal offers), this means the agent's messages stay contextually threaded even when channel-switching logic kicks in.

5. Security Hardening — Production-Ready

v2026.4.10 ships the most comprehensive security update in OpenClaw's history: tightened SSRF defaults, exec preflight hardening, outbound host-media access control, plugin install dependency scanning, and Gmail watcher token redaction. If you're running a self-hosted OpenClaw instance handling real customer data, this upgrade is not optional.

FAQ

Q: Do I need to reconfigure my existing SDR agent to get Active Memory? A: Active Memory is opt-in. Your existing setup keeps working unchanged. To enable it, add plugins.slots.contextEngine: active-memory to your config and choose a mode (recent is recommended for SDR).

Q: Does Teams integration work with Microsoft 365 Business Basic? A: Yes — the delegated OAuth path (v2026.4.11) works with any Microsoft 365 tenant that allows third-party app registration. Bot Framework app registration is required for application-auth read paths.

Q: Will the WhatsApp reconnect fix help with the 24-hour business messaging window? A: Indirectly, yes. The fix prevents queued outbound messages from being lost during reconnects, so time-sensitive replies within the 24h window are more reliably delivered. The window expiry logic in your HEARTBEAT checks is unchanged.

Q: I'm on v2026.4.9. Should I upgrade directly to v2026.4.11? A: Yes — skip v2026.4.10 in place and install v2026.4.11 directly. All v2026.4.10 features and fixes are included.

Q: What model should I use for the Active Memory sub-agent? A: The Active Memory plugin defaults to a haiku-class (fast, cheap) model for memory retrieval. For SDR workloads with large contact histories, this is the right choice — the main reply model handles the actual sales conversation.
