Umbraco V17: Everything you need to know

Umbraco V17 is built on Microsoft’s latest technology (.NET 10). This provides a stable and secure foundation that organizations can rely on for years to come.

In practice, this means less worry about maintenance and more confidence that your website will keep running smoothly. At the same time, developers can work faster and more efficiently, often resulting in better website performance.

In Umbraco V17, the backoffice—the place where you manage your website—has been greatly improved. Whereas it used to run on a single server, it can now run across multiple servers at the same time.

In practice, this means the backoffice is faster and more stable, especially when many people are working on the website simultaneously. Multiple editors can update content at the same time without issues, the chance of downtime is reduced, and everything keeps running smoothly.

In Umbraco V17, dates and times are stored in the same way everywhere. This ensures that everyone, no matter where they are in the world, sees the same time.

In practice, this makes scheduled publications—such as when a page goes live—more reliable. Reports and logs are also clearer and easier to understand.

Planning content has also become easier. There’s a new date and time picker that supports time zones. Editors only see the time zones relevant to them, which is especially helpful for organizations operating internationally.

In 2025, the Umbraco backoffice was reviewed by an accessibility expert. Many of the improvements from that review have been implemented in Umbraco V17, making the backoffice more consistent and predictable.

Editors who use assistive tools, such as screen readers, also benefit from these updates. Some technical improvements are still being finalized and are expected to be released in 2026. All of these updates make the backoffice easier and more efficient to use for everyone.
