Customer.io is widening what a journey can express and where its agent can be reached.
Two threads run side by side. The automation engine keeps gaining expressiveness: per-channel rate limits in early August, and now a Wait Until block that accepts multiple delays, time windows, and And/Or/nested condition groups. Separately the AI agent moved into Slack, while messaging reach grew with transactional WhatsApp and support for multiple mobile apps in one workspace.
n8n ships 2.40.0 with AI builder hardening while laying v3 storage migration groundwork
n8n is running an unusually high release cadence—multiple patch releases per day across both the v1 LTS and v2 main line. The 2.40.0 minor release advances the ai-builder surface with better 429 error handling on channel integrations, reusable credential display for Instance AI agents, and a fix that correctly preserves Anthropic extended-thinking blocks across multi-tool-call chains. API key scoping now allows global members to grant folder-level permissions, giving enterprise deployments finer access control.

Separately the AI agent moved into Slack, while messaging reach grew with transactional WhatsApp and support for multiple mobile apps in one workspace.
The Wait Until change is the clearest read on where the builder is heading: logic that previously needed a chain of wait steps now collapses into one block, which makes journeys shorter and harder to misread. Paired with rate limits and the wait-before-continuing option, timing and pacing are becoming first-class controls rather than things you assemble from primitives. The agent work runs on a separate track, pushing the product into tools people already sit in.
Expect the nested And/Or condition model to spread from Wait Until into other branching actions, since the release describes grouping as a property of the path rather than of that single block.

n8n is hardening its agentic AI infrastructure release by release: the ai-builder receives iterative UX improvements, the AI Agent node is being shored up for production multi-step chains, and MCP toolkit execution has been extended to distributed worker nodes. A v3 storage migration is being prepared in parallel—a storage directory rename with an explicit breaking-change migration rule now baked into the release pipeline—which means self-hosted operators will need to update paths and env vars before upgrading to v3.
v3 will ship the storage directory rename as its primary breaking change, following the deprecation warnings and migration rules being added now; operators relying on N8N_DB_PING_TIMEOUT or legacy storage paths should audit configurations ahead of the major version.
