What is Mautic?
Mautic is patching three supported branches at once while 7.2 grinds through release candidates.
The project maintains 5.2, 6.0, and 7.1 simultaneously, and it showed: one coordinated security release patched SQL injection, SSRF, and server-side template injection across all three branches on the same day. Since then the visible work has been a 7.1.3 bugfix rollup — campaign restart and infinite email-resend loops, GrapesJS builder regressions — and a 7.2 release candidate line now on its second RC, tagged in late July with no compiled release notes.
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.

Mautic
5.0MKT AUTO
Mautic is patching three supported branches at once while 7.2 grinds through release candidates.
◆ Current state
The project maintains 5.2, 6.0, and 7.1 simultaneously, and it showed: one coordinated security release patched SQL injection, SSRF, and server-side template injection across all three branches on the same day. Since then the visible work has been a 7.1.3 bugfix rollup — campaign restart and infinite email-resend loops, GrapesJS builder regressions — and a 7.2 release candidate line now on its second RC, tagged in late July with no compiled release notes.
◆ Where it's heading
This is maintenance-shaped output from a community project carrying a wide support matrix. The 7.2 RC notes are dominated by dependency bumps, refactoring, and developer-experience work rather than new marketing automation capability, and the campaign engine keeps surfacing scheduling bugs that suggest that subsystem is where the complexity sits. A second RC without notes points to stabilisation rather than late feature additions.
◆ Prediction
Expect 7.2.0 to reach stable off the current RC line, and expect any further fixes to be backported across all three supported branches as the coordinated May security release was.

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.
