Sulu ships 2.6 and 3.0 in lockstep, and the 3.0 line still reads like a maintenance branch.

What is Customer.io?
Location becomes a trigger, Twilio stops being the only SMS path, and the LLM layer gets a memory
The summer window widens both ends of the automation graph. On the input side, geofences turn physical entry and exit into workflow triggers and date triggers now read attributes off custom objects; on the output side, SMS opens to Sinch, Infobip, and Vonage instead of Twilio alone, and live notifications add a persistent, continuously updating message format on iOS and Android. The LLM side gains a workspace-scoped Knowledge Library that both LLM actions and the Agent can read, replacing per-prompt copy-paste. Channel-based message limits and unsubscribe-preserving profile merges tighten the send-side guardrails underneath all of it.
What is n8n?
n8n's daily patch train hides the real work: hardening its MCP server into a proper auth resource.
n8n ships patches almost daily across three live branches (2.31.x, 2.32.x, 2.33.x), so the changelog reads mostly as noise. Underneath it, nearly every substantive commit lands in one of two places: the AI agent builder and the MCP server. The 2.33.0 minor is the clearest example, a very large bundle with no features section at all, only fixes.

Location becomes a trigger, Twilio stops being the only SMS path, and the LLM layer gets a memory
◆ Current state
The summer window widens both ends of the automation graph. On the input side, geofences turn physical entry and exit into workflow triggers and date triggers now read attributes off custom objects; on the output side, SMS opens to Sinch, Infobip, and Vonage instead of Twilio alone, and live notifications add a persistent, continuously updating message format on iOS and Android. The LLM side gains a workspace-scoped Knowledge Library that both LLM actions and the Agent can read, replacing per-prompt copy-paste. Channel-based message limits and unsubscribe-preserving profile merges tighten the send-side guardrails underneath all of it.
◆ Where it's heading
Customer.io is systematically loosening the assumptions its automation graph was built on: one workspace one app, one SMS vendor, one blunt frequency cap, prompts as the only place LLM context can live. Each release swaps a hardcoded shape for a configurable one, which is what a platform does when its largest accounts have outgrown the original model. The AI work follows the same instinct — not a chatbot bolted on, but retrieval and context turned into workspace-level objects that the rest of the system can reference.
◆ Prediction
Expect the Knowledge Library to spread past LLM actions into more of the Agent's surface, and the per-channel controls to keep filling in — the release notes name WhatsApp and SMS capping outside Twilio as a live gap, which is an odd thing to leave open right after opening SMS to three new vendors.
n8n
5.0MKT AUTO
n8n's daily patch train hides the real work: hardening its MCP server into a proper auth resource.
◆ Current state
n8n ships patches almost daily across three live branches (2.31.x, 2.32.x, 2.33.x), so the changelog reads mostly as noise. Underneath it, nearly every substantive commit lands in one of two places: the AI agent builder and the MCP server. The 2.33.0 minor is the clearest example, a very large bundle with no features section at all, only fixes.
◆ Where it's heading
The MCP work has moved past merely exposing a server toward protocol compliance: OAuth protected-resource metadata served at the bare well-known path, the RFC 9207 iss parameter on authorization error redirects, PKCE negotiation and token expiry handling. Agent-side changes point the same direction, with secrets scrubbed before they reach agent memory, MCP connection failures made non-blocking for agents, and workflow deletion refused while an unpublish is still running. This is the unglamorous half of making agents safe to run inside someone else's instance.
◆ Prediction
With the auth and audit plumbing largely landed, the next visible move is agent capability that depends on it, such as delegated MCP access, rather than another round of protocol fixes.
