For customers using unsupported versions older than 13.3 or within the 14.x range, upgrading to a supported version is strongly desired. The latest Long-Term Support (LTS) options include 13.3 LTS and 14.4 LTS as well as the latest available version within the 15-product line – Sitefinity 15.2. These versions uphold continued security, stability and support.
If your project still relies on Web Forms or if your pages are written using a hybrid approach (Web Forms + MVC within the same page), consider modernizing your front-end by transitioning to ASP.NET Core or Next.js for better performance, flexibility and futureproofing.
Additionally, migrating to Sitefinity Cloud can help streamline future upgrades, reduce maintenance efforts and improve scalability.

* Progress strongly advises against using Web Forms for production deployments in any version beyond 13.3 LTS, which remains the last officially supported versionfor Web Forms. Customers who choose to deploy Web Forms-based websites on versions beyond 13.3 do so at their own risk. Web Forms capabilities are no longer eligible for support, feature development or bug fixes - including security updates. Any newly introduced or discovered issues, including critical bugs without workarounds, will not be addressed.
