What’s New in Sitefinity: Six Updates You Need to Know in 2025

Sep 29, 2025

Sitefinity has been busy in 2025. From the launch of its AI Assistant and native Next.js support to smarter analytics and an upcoming LTS release, these updates reshape how organizations build and manage digital experiences. Learn what’s new and how Enqbator can help you take advantage of these changes.

The pace of innovation in digital experience platforms is accelerating, and Progress Sitefinity is keeping stride. Over the past year, Sitefinity has rolled out meaningful enhancements that improve how teams build, manage, and personalize content. Here’s a clear rundown of six updates that matter and why they’re worth your attention.

1. Sitefinity AI Assistant goes mainstream

Sitefinity introduced an AI Assistant for Cloud customers on modern versions. Powered by Azure OpenAI, it gives your site a chat-style interface so visitors can ask questions and get answers from your content in seconds. You can embed it via a widget, configure scope, and keep multiple assistants for different audiences.

Why it matters: It turns large content libraries into quick answers. Ideal for help centers, patient education, policy portals, and documentation sites.

2. Native Next.js support

Developers can pair Sitefinity’s enterprise CMS with a modern Next.js front end. This brings fast rendering, great SEO, and a clean path to headless and composable architectures without giving up Sitefinity’s editorial tools.

Why it matters: You get the best of both worlds — a modern React experience for users and a familiar admin experience for editors.

3. Sitefinity 15.3 doubles down on AI

  • AI content refinement and optimization right inside the editor
  • Natural language media search to find images faster
  • Azure AI Translator integration for multilingual publishing
  • Usability upgrades for widgets, layouts, and in-place editing

Why it matters: Marketers move faster while keeping quality high, and editors spend less time hunting for assets or rewriting content from scratch.

4. Lifecycle policy and the road to 15.4 LTS

Progress updated the lifecycle policy so teams can plan upgrades with confidence. Version 15.3 is current, and 15.4 is expected to be the next Long-Term Support milestone.

Why it matters: If you are on older versions, now is the moment to schedule your upgrade so you keep security fixes, support, and modern features.

5. Sitefinity Insight gets smarter

Sitefinity Insight added improvements across analytics and personalization, including better journey mapping, segmentation, and onboarding so teams can act on data faster.

Why it matters: Clearer insights lead to better targeting and higher conversion, especially when paired with the new AI tools.

6. Progress expands its AI vision

Progress is investing in retrieval-augmented generation and semantic search that complement Sitefinity. Expect tighter connections between your content, search, and personalization as these capabilities evolve.

Why it matters: Your CMS becomes an intelligent layer that can recommend, summarize, and guide users to the right answer faster.

What this means for you

From conversational AI and smarter editing to Next.js front ends and a clearer upgrade path, Sitefinity is pushing forward on both marketer and developer needs. If you require compliance, performance, and flexibility, these updates open doors for better experiences with less maintenance overhead.
