What is Cello?
Cello is wrapping its referral platform in AI assistants — for growth managers, referrers, and now AI coding tools via MCP.
Cello has been shipping every week, layering in three parallel AI surfaces: an in-portal Assistant for growth managers, AI-powered sharing-message suggestions for referrers, and a brand-new MCP Server that lets developers' AI tools introspect, validate, and recommend changes to a Cello account. Around those, the team is hardening the developer experience (Event Feed for integration debugging, Flutter SDK in beta) and polishing the referrer widget (dark mode, dual-offer layouts, micro-loop reminders).
What is Umbraco CMS?
Umbraco 19's first beta moves to .NET 11 and puts reusable content in every block editor.
Umbraco has three lines moving at once. The first 19.0 beta moves to .NET 11, extends reusable Library content to every block editor and brings search into core. The 18.3 and 17.8 candidates are on a second round, and rc2 on both lines resolves the same seven security advisories, among them a backoffice account takeover through sign-in redirect manipulation.

◆ Current state
Cello has been shipping every week, layering in three parallel AI surfaces: an in-portal Assistant for growth managers, AI-powered sharing-message suggestions for referrers, and a brand-new MCP Server that lets developers' AI tools introspect, validate, and recommend changes to a Cello account. Around those, the team is hardening the developer experience (Event Feed for integration debugging, Flutter SDK in beta) and polishing the referrer widget (dark mode, dual-offer layouts, micro-loop reminders).
◆ Where it's heading
Cello is positioning itself as the AI-augmented referral platform across three personas: program operators get AI recommendations and benchmarks, end-users get AI-assisted personalization, and developers get an MCP Server they can wire into their own coding agent. Performance Benchmarks and Recommendations indicate Cello also wants to own the optimization layer, not just the rails — telling customers what to do next, not only what's happening.
◆ Prediction
Expect the MCP Server and AI Assistant to converge — likely an agentic workflow where the AI Assistant proposes a change and an MCP-connected coding agent applies it. Mobile (Flutter, the existing React Native and iOS/Android components) will probably keep gaining feature parity since referral flows are still desktop-biased today.
Umbraco CMS
6.3MARKETING
Umbraco 19's first beta moves to .NET 11 and puts reusable content in every block editor.
◆ Current state
Umbraco has three lines moving at once. The first 19.0 beta moves to .NET 11, extends reusable Library content to every block editor and brings search into core. The 18.3 and 17.8 candidates are on a second round, and rc2 on both lines resolves the same seven security advisories, among them a backoffice account takeover through sign-in redirect manipulation.
◆ Where it's heading
The maintenance phase visible through September has given way to a major-version cycle. Version 19 consolidates work that had been spread across packages and settings: search moves from a package into core, and Document Blueprints move from Settings to the Library. Its breaking list is long, covering ImageSharp 4, the segment model and the removal of code scheduled for 19, and 18.3's ImageSharp licence check is already catching projects that reference that package directly.
◆ Prediction
18.3.0 and 17.8.0 are dated 29 October on GitHub, though neither has reached this feed yet. The 19 line should continue through further betas, with runtime async the item the team has singled out for feedback.
