That means three years of guaranteed stability, updates and security fixes, making it the most reliable foundation for new projects or long-term upgrade paths.
Why Umbraco 17 Matters
This isn’t just a small step forward. Version 17 introduces a rethink of how the back office works and how extensions are built. Key changes include:
- Modern Frontend Architecture using Lit and web components, delivering faster performance and a cleaner development experience
- Extensions Reimagined with custom functionality and packages needing updates to fit the new framework, bringing more consistency and flexibility
- Aligned with .NET 10 for a modern, future-proof development stack
For editors this should mean a more responsive, user-friendly experience. For developers it’s a chance to work with a more modern, maintainable platform.
From 16 to 17
Umbraco 16 introduced some important stepping stones, including a brand new Rich Text Editor (RTE). This editor is faster, easier to use and more consistent across content. Sites moving from v15 or earlier will benefit from this upgrade before stepping into the broader changes in 17.
Why LTS Versions Matter
Running on an LTS version means:
- Ongoing security updates and bug fixes for three years
- Less pressure to upgrade with every minor release
- A stable platform for long-term projects
In short, if you’re starting a new Umbraco project, targeting 17 is the smart choice.
Preparing for the Upgrade
For teams on v13 or earlier, moving to 17 will take planning, especially if you rely on custom extensions. We’ll be working closely with clients to map out upgrade paths that keep projects stable while unlocking the benefits of the latest platform.
