What is Customer.io?

Customer.io spent the summer pushing messaging off the screen and into location, time, and the lock screen

The summer release cycle put more than ten features into the product, and the coherent ones are about context rather than content: geofences trigger workflows when someone enters or leaves a physical location, live notifications render as iOS Live Activities and Android Live Updates, date triggers now read attributes on custom objects, and a notification inbox retains pushes. Around that sits infrastructure work — SMS via Sinch, Infobip and Vonage, multiple mobile apps per platform in one workspace, send-rate controls on automations — and an LLM actions surface where knowledge sources can be attached once and reused across prompts. The most recent entry is editor ergonomics in Design Studio.

◆ Current state

The summer release cycle put more than ten features into the product, and the coherent ones are about context rather than content: geofences trigger workflows when someone enters or leaves a physical location, live notifications render as iOS Live Activities and Android Live Updates, date triggers now read attributes on custom objects, and a notification inbox retains pushes. Around that sits infrastructure work — SMS via Sinch, Infobip and Vonage, multiple mobile apps per platform in one workspace, send-rate controls on automations — and an LLM actions surface where knowledge sources can be attached once and reused across prompts. The most recent entry is editor ergonomics in Design Studio.

◆ Where it's heading

The platform is expanding the set of things that can start a message and the set of places one can land, which is a different axis from the segmentation-and-copy tooling most of this category competes on. Geofences and live notifications both take work that previously required a specialist vendor or custom device code and make it a workflow primitive. The LLM actions work is following the same instinct — reusable knowledge sources are the beginning of prompt infrastructure rather than a prompt box — but it is the least developed of the threads. Meanwhile send-rate control and multi-app support read as enterprise deployment blockers being cleared.

◆ Prediction

Expect the location and live notification surfaces to gain the operational controls that continuous device features require, and the LLM actions path to keep accreting reusable pieces. Design Studio is receiving steady editor polish, so a broader component authoring release is plausible.

OpenEMM 26.11 reaches GA eight days after its beta.

◆ Current state

OpenEMM released 26.11.169 as the general-availability build of the 26.11 line on November 12, eight days after the 26.11.136 beta. The notes list only the frontend version. The 26.05 line it replaces reached GA in July and has had only frontend builds since.

◆ Where it's heading

OpenEMM keeps its twice-yearly cycle: a beta, a GA, then months of frontend-only maintenance builds. The notes never say what a line changes, so the cadence is the only visible signal.

◆ Prediction

Expect frontend-only 26.11 maintenance builds over the coming months; the entries give no hint of feature content.
