Umbraco 17: LTS and built for growth, stability, and scale
Umbraco version 17 is a Long-Term Supported version of Umbraco CMS. This means Umbraco 17 brings a stable and supported foundation until November 27, 2028.
Whether you're starting a new project on Umbraco 17 or upgrading from a previous version of Umbraco, this release is packed with helpful, modern features for editors and developers alike.
Umbraco 17 is the current active version of Umbraco - available on Umbraco Cloud and NuGet.
Key Features of Umbraco 17
Runs on Microsoft .NET 10 LTS
By being updated to the latest .NET version, you can take full advantage of all the latest optimisations and feature improvements on .NET. And like Umbraco 17, .NET 10 is a LTS version, which means that your Umbraco 17 projects will be future-proofed until Q4 2028.
Load balancing the Backoffice
With Umbraco 17, the backoffice can be set up to run across multiple servers just like the front-end website. This means better performance for busy and big content teams, improved resilience, and a simpler infrastructure overall.
Consistant handling of dates
All system dates (creation, updates, publishing, logs, etc.) are now stored and exposed in UTC, with a built-in migration that updates existing data automatically. With this, you get a new Date Time Picker that includes date, time, and timezone selection.
Cloud-Ready from Day One
Umbraco 17 is available immediately on Umbraco Cloud, which include Umbraco Deploy and Forms. This ensures fast onboarding and scalable, managed hosting on the latest Umbraco version.
The jump from Umbraco 13 to 17
We know that many go from one LTS version to the next, taking full advantage of 3 years of feature stability and no breaking changes. Now it's time to jump to the next LTS, and Umbraco 17 is a milestone upgrade for many, as it involves the migration to a new and modern backoffice architecture (introduced in Umbraco 14).
To help ease the jump from Umbraco 13 to 17, we have gathered all changes - and how to handle them - in the Umbraco 17 beta blog post.
The latest and greatest features
Umbraco version 17 is the active version of Umbraco CMS, receiving new features and improvements until Umbraco 18 is released in Q2 2026. After that, Umbraco 17 will continue to receive 18 months of bug, regression, and security fixes, followed by a final 12 months of security-only fixes.
Running your website or project on an LTS version ensures access to the latest features and improvements while staying fully supported for 3 years without major breaking changes.
Being on the latest version also provides a smooth path to the next major Standard-Term Supported (STS) version of Umbraco.
