UMBRACO updates

Get maximum benefit from your Umbraco site with the latest updates and releases. Our Certified Umbraco team is ready to help you with a migration.

Therefore, you should migrate to the latest Umbraco version

The latest Umbraco release always includes the newest functionalities.


Additionally, the following improvements are ensured:


  • Security: Updates in the latest version of Umbraco CMS often include important security patches that protect your website from known vulnerabilities. By migrating to the latest version, you can benefit from enhanced security and reduce the risk of your website being compromised.

  • Performance: Newer versions of Umbraco may have performance optimizations and improvements that make your website faster and more responsive. This can enhance the user experience and contribute to better search engine rankings.

  • Functionality: Each version of Umbraco typically introduces new features, improved user interface, and updates to existing functionality. By migrating to the latest version, you gain access to these features, which can enhance the editing experience for content editors and provide you with more tools to manage and expand your website.

  • Support and maintenance: As an open-source platform, Umbraco relies on an active community and a large developer network. By keeping yourself up to date and on the latest version, you can receive better support from the community and also benefit from updates and bug fixes performed by the Umbraco team.

  • Compatibility: When using older versions of Umbraco, compatibility issues can arise with third-party add-ons and integrations. By migrating to the latest version, you ensure the best compatibility with the latest setup of add-ons and tools available to Umbraco users.


It's important to note that migrating to the latest version of Umbraco CMS requires planning, testing, and implementation to ensure a seamless transition. It may be a good idea to involve an experienced Umbraco developer who can assist you through the process and ensure everything works as expected after an upgrade.


We recommend always keeping up with the new releases.

If you are currently working on, for example, Umbraco 8, you cannot immediately migrate to the latest version. Continuous migration is needed from Umbraco 8 to Umbraco 9, and then to Umbraco 10, and so on.

It can be a substantial effort, so instead, you should regularly ensure the update of your Umbraco site.

Umbraco releases

Starting from the release of Umbraco 9 (September 2021), a new and improved version (major) is released twice a year. This means that approximately every six months, you should upgrade your current Umbraco version if you want to ensure that you are always working with the best software.


Every 4th major version (every two years) will be long-term supported (LTS), while the remaining versions will be standard-term supported (STS).


Note that all versions before Umbraco 7 are no longer supported.



Long-term Support (LTS)

LTS consists of two phases: the support phase and the security phase.


The support phase begins immediately after a major release. Its purpose is to fix errors and issues and lasts for 9 months. For an LTS release, the support phase lasts for 12 months.


Following that is the security phase, during which only security-related issues are addressed. This phase lasts for 3 months and is extended to 12 months for an LTS release.



End-of-Life (EOL)

After the security phase, the release is considered End-of-Life (EOL), and it is no longer recommended to use it.


Read more about LTS and EOL here.



Umbraco also releases small updates and additions to the current CMS every 6 weeks. The purpose of these is to introduce new features, and they consist of minor improvements and non-disruptive changes.


Patch versions are released as needed and primarily address regression issues (bugs in the latest minor release) and, in some cases, security issues.


When using Umbraco Cloud, all new projects are based on the current major version of Umbraco CMS by default. However, if you want to create a new project on a previous major version, that is possible.


And Umbraco Heartcore is automatically upgraded, so there are no concerns regarding LTS and EOL.

That's what our partners say

Social og Sundhedsskolen
We are very informal ourselves, and that was also what we where looking for in a bureau. It may well be too large and formal for many agencies. So we were looking for something informal and where we are at eye level with those we are talking to. And we have experienced that at MCB.

We have been very happy with the collaboration with Tine who has always been easy to get in touch with, and she has listened to us and challenged us.

MCB has been very responsive and has taken our ideas and brought them to life for us. And they have done it in a way that does not feel like sales at all costs. Bo has been very honest several times when solutions and ideas have not been financially viable for us. And we are happy about that honesty.

Umbraco 9 has reached its End-of-Life. The version is no longer supported, and we recommend that you do not use it.

Three features, in particular, stand out compared to Umbraco 7:

  • Infinite Editing: Your ability to experience a more streamlined and uninterrupted workflow.
  • Language Variants: Built-in features that assist in managing multilingual content.

What happens to previous Umbraco versions?

Technically, you can still use previous versions after their End-of-Life, but it is not recommended.

Here are the implications:


  • Risk of security issues: After EOL, no security patches or updates will be provided. While the software may still function, there is no guarantee that it will remain as secure as possible.

  • No guarantee of bug fixes: Any discovered bugs will not be addressed. This also means that your Backoffice may be affected as web browsers automatically update, and any changes in browser behavior can impact your Backoffice.

  • Outdated features and lack of new functionalities: You won't have access to the latest features, and you won't be working with the fastest and best version of Umbraco CMS. The CMS may also not be as reliable and user-friendly as you would like.
    It is therefore recommended to stay up-to-date with the latest supported version of Umbraco CMS to ensure security, stability, and access to the latest features and improvements.
