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 reaches its first release candidate on .NET 11 GA.
Umbraco 19.0.0-rc1 arrived on 12 November, two weeks after the first beta, and moves the release onto .NET 11 GA. The beta brought reusable Library content to every block editor and search into core; rc1 adds Entra ID SQL authentication, action groups in menus, an API switch that lets code block schema changes per environment, and a fix that admits one request per process into the content write path on load-balanced sites. The 18.3 and 17.8 candidates are still on rc2, which resolved seven security advisories.

◆ 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 reaches its first release candidate on .NET 11 GA.
◆ Current state
Umbraco 19.0.0-rc1 arrived on 12 November, two weeks after the first beta, and moves the release onto .NET 11 GA. The beta brought reusable Library content to every block editor and search into core; rc1 adds Entra ID SQL authentication, action groups in menus, an API switch that lets code block schema changes per environment, and a fix that admits one request per process into the content write path on load-balanced sites. The 18.3 and 17.8 candidates are still on rc2, which resolved seven security advisories.
◆ Where it's heading
The 19 cycle is moving quickly from beta to candidate, and rc1 is about hardening rather than new editor features: dependencies on GA, environment-level permissions and load-balancing performance. The 17 and 18 lines are kept in step on security fixes while 19 matures.
◆ Prediction
Expect 18.3 and 17.8 to go stable, followed by further 19 release candidates and a 19.0.0 stable release built on .NET 11.
