Release: 17.0.0

[github-actions[bot]]

Release date: 2025-11-27
Long term supported version? Yes

Umbraco 17 is the new Long-Term Support (LTS) release, marking a stable foundation for many years of updates.

Extensions are now first-class citizens: older extension methods are phased out with clear, supported alternatives.

New features include support for .NET 10, load-balanced backoffice, and consistent UTC date handling with time zone support.

Direct LTS-to-LTS upgrade is supported, e.g., from Umbraco 13 straight to 17 (with migrations applied automatically).
