What’s new in Nimbus

You can now browse and install pre-built AI agents directly from the Nimbus Marketplace. Over 40 agents are available at launch, covering lead routing, support triage, churn detection, and onboarding automation. Install any agent in one click and customize its triggers and actions to fit your workflow.

Marketplace agents are maintained by Nimbus partners and the community. Each agent includes usage documentation, required integrations, and a sandbox preview mode before you go live.

Every change to a workflow is now versioned automatically. You can view a full history of edits, see what changed between versions, and restore any previous state with one click. Version history is retained for 90 days on all plans.

This makes it safe to experiment — if an edit breaks a production workflow, rolling back takes seconds. Each version also includes the editor’s name and a timestamp, visible in the activity log.

Workflow cold start time has been reduced from an average of 340ms to under 80ms across all regions. This improvement is the result of pre-warming our runtime containers and optimizing the graph initialization layer.

Synchronous workflows that previously felt slightly delayed — like approval flows responding to a form submit — should now feel nearly instant.

Resolved a bug where HubSpot contact sync would create duplicate records when a workflow was triggered within 200ms of a previous run for the same contact ID. This affected approximately 0.4% of HubSpot-connected workspaces.

Affected workspaces have been identified. Duplicate records created between May 10–25 can be cleaned up using the new deduplication tool under Settings → Integrations → HubSpot.

The authentication header for outbound webhooks has changed from X-Nimbus-Token to Authorization: Bearer. This aligns with industry standards and simplifies integration with third-party services that expect standard Bearer auth.

If you have existing webhook steps you will need to update your receiving endpoints to read the new header format. The old header will continue to be sent in parallel through June 30, 2026 to give you time to migrate.
