Sitefinity 15.4 Update: AI-Ready CMS Features That Help Marketers Get Things Done
March 31, 2026
AI discovery is replacing “10 blue links.” This post breaks down what’s new in Sitefinity 15.4—AI-friendly structured content, built-in SEO and Brand Agents, RAG retrieval and dynamically generated experiences—so your content stays visible in both search engines and AI assistants.
Long story short, the Feather projects hosted on GitHub will be no longer our primary source for a build. It will be a mirror repo of Feather’s implementation without having control over it.
Serving content to your audience is hard when you have different groups of people to target. For those cases generic content or long articles targeting everyone are not a good option. The simplest solution is to use personalized articles and pages. In the context of Sitefinity, this is an easy job.
Today I’m excited to announce the release of Sitefinity 10, which focuses on enterprise-grade identity management, security, performance and increased developer productivity that IT Administrators and Developers are going to enjoy. Don’t worry Marketers, there’s plenty of love for you as well.
