OpenClaw’s latest release lands with a handful of features that significantly expand what you can do with headless and long-running agents. Version 2026.4.8 — a hotfix over 4.7 — ships four meaningful upgrades: the new openclaw infer unified CLI, Git-like session branching and restore, webhook-driven TaskFlows, and the experimental memory-wiki plugin. It also officially retires the legacy Claude CLI backend from the onboarding flow.
If you’re running OpenClaw in production, this one is worth a careful read.
The openclaw infer CLI: Headless Scripting Just Got Easier
The most developer-facing addition in 4.8 is the openclaw infer command. This is a unified CLI interface for headless agent scripting — meaning you can now trigger single-turn agent executions directly from shell scripts, cron jobs, or CI/CD pipelines without spinning up a full interactive session.
Previously, automating agent invocations required working around the session model or using the API directly. openclaw infer wraps that complexity into a single, composable command. Think of it as the equivalent of running curl against a language model — but with full OpenClaw context, tool access, and provider routing baked in.
openclaw infer --prompt "Summarize recent errors in logs/app.log and file a GitHub issue if critical"
This unlocks a much cleaner path for scheduled agentic tasks, monitoring workflows, and pipeline integrations that don’t need a persistent session at all.
Session Branching: Git for Your Agent Conversations
Session branching is the sleeper feature of this release. OpenClaw now lets you branch and restore sessions in a Git-like model — you can checkpoint the current state of a session, experiment down a particular reasoning path, and then restore back to the branch point if things go sideways.
For anyone running complex multi-step agentic workflows, this is a major reliability upgrade. You no longer have to start from scratch if an agent makes a wrong decision halfway through a debugging or refactoring task. Branch, test, restore. Same mental model as feature branches in code.
The implementation hooks into the existing session store, so there’s no new infrastructure to set up. It’s a first-class capability in 4.8.
Webhook-Driven TaskFlows
TaskFlows — OpenClaw’s declarative task sequencing system — can now be triggered by external webhooks. This means your agents can be kicked off by GitHub push events, PagerDuty alerts, Stripe webhooks, or any system that can fire an HTTP POST.
For ops-heavy teams, this is the missing link between event-driven infrastructure and agentic automation. Set up a TaskFlow that runs a diagnostic and sends a Slack summary whenever a Datadog alert fires. Or trigger a code review agent every time a PR is opened. The surface area for agentic automation just got considerably larger.
New Model Support: Gemma 4 and Arcee Trinity
4.8 adds native provider support for Google’s Gemma 4 and Arcee Trinity. Both can now be configured directly in OpenClaw’s model routing without custom provider definitions. Gemma 4 in particular is an interesting addition given its strong performance on coding and instruction-following benchmarks at smaller parameter counts.
memory-wiki: Persistent Structured Knowledge (Experimental)
The memory-wiki plugin is experimental, but it’s the most conceptually interesting addition in this release. It gives agents a persistent, structured knowledge base that persists across sessions — think of it as a living wiki that your agent can read from and write to over time.
The key differentiator from standard memory systems is contradiction detection. When the agent writes a new fact that conflicts with an existing entry in the wiki, the plugin flags it for review rather than silently overwriting the prior belief. That’s a meaningful step toward more trustworthy long-running agents that build up knowledge over time without accumulating silent errors.
The plugin is marked experimental — expect APIs to shift — but the core concept is solid. A dedicated how-to on setting it up is available at /howtos/setup-memory-wiki-plugin-openclaw/.
Migrating: Run openclaw doctor –fix
With 4.8, the legacy Claude CLI backend has been removed from the onboarding flow. If you’re upgrading from an older installation, run:
openclaw doctor --fix
This detects and migrates any stale configuration referencing the old backend. The command is non-destructive and idempotent — safe to run more than once.
Why This Release Matters
v2026.4.8 isn’t a single splashy feature drop — it’s a collection of capabilities that collectively push OpenClaw toward a more complete agentic runtime. The infer CLI makes agents scriptable. Session branching makes long-running agents recoverable. Webhook TaskFlows make agents event-driven. And memory-wiki starts to address the hardest problem in persistent agents: maintaining a coherent, accurate knowledge state over time.
The hotfix packaging (over 4.7) and the bug fixes included — particularly around Slack proxy support, Telegram sidecar loading, and exec host-awareness — suggest the OpenClaw team is also doing the unglamorous work of making the runtime more reliable across diverse deployment environments. That’s just as important as the headline features.
