General release information
Umbraco CMS, known for its flexibility and user-friendliness, has a structured release cycle. This cycle ensures that users regularly have access to new features, improvements, and security updates.
Release cycles and cadences of Umbraco
To keep the development of Umbraco CMS predictable and structured, Umbraco follows a clearly defined release cycle and cadence. This system ensures that users have regular access to new features, enhancements, and essential security updates.
Major releases
Twice a year, Umbraco releases a major update. These releases include significant updates, such as new features, improvements, and sometimes breaking changes. Major releases are often linked to the latest developments in the .NET framework, keeping the platform up-to-date with the latest technologies.
Minor releases
Every six weeks, a minor release is issued. These releases include new features and functionalities that are backwards compatible. They do not contain breaking changes and are aimed at further refining and expanding the capabilities of the CMS.
Patch releases
Patches are released as needed. They primarily focus on fixing regression issues (bugs in the latest minor) and, in some cases, on security issues.

Short-Term Support (STS) and Long-Term Support (LTS) in Umbraco
Umbraco offers two types of support for its releases to meet various user needs: Short-Term Support (STS) and Long-Term Support (LTS).
- Short-Term Support (STS): STS releases have a shorter lifespan and are ideal for users wanting quick access to new features. These releases receive full support until the next STS or LTS release, followed by a three-month security-only phase.
- Long-Term Support (LTS): LTS releases, released every fourth major release and synchronised with .NET LTS releases, provide long-term stability for larger projects. They receive nine months of full support followed by twelve months of security-only support.

End-of-Life (EOL) of older Umbraco versions
The End-of-Life (EOL) concept is a crucial aspect of the lifecycle of software products, including Umbraco CMS. EOL marks the point at which a specific version of Umbraco no longer receives official support or updates. This includes the termination of both the 'Support' and 'Security' phases.
For older versions of Umbraco, such as Umbraco 7, 9 and 11, reaching EOL status has specific implications:
- No further updates: After the EOL date, these versions will no longer receive patches, security updates, or new features.
- Security risks: Continuing to use a version that has reached EOL can lead to increased security risks, as any new security vulnerabilities will not be addressed.
- Recommendation to upgrade: Users of older Umbraco versions are strongly advised to upgrade to a more recent, supported version of the CMS to benefit from enhanced features, better performance, and, most importantly, improved security.
- No further support from Umbraco available: This means that in the event of unforeseen challenges or issues, we can no longer rely on Umbraco's support.
Umbraco releases: support and security phases
To ensure the safety and stability of the Umbraco CMS platform, Umbraco provides a clear framework of support and security phases for the maintenance and upgrade of each major release. This system ensures that users and developers always have access to a reliable and secure CMS while benefiting from the latest features and improvements.
- The 'support' phase Each major release of Umbraco has a 'Support' phase of 9 months, extended to 24 months for LTS versions. During this phase, Umbraco addresses bugs, regressions, and security issues. New projects can be initiated in Umbraco Cloud. The focus is on stability with critical fixes, without new features.
- The 'security' phase After the 'Support' phase comes the 'Security' phase, which lasts for 3 months, or 12 months for LTS versions. Here, Umbraco focuses exclusively on security issues. At the end of this phase, the version reaches End Of Life (EOL) and its use is discouraged.
- Patches Patches typically target the latest minor of a major release. Critical security patches may also focus on earlier minors, depending on the situation. In Umbraco cloud, these are applied automatically. Minor updates can be optionally set to automatic in the cloud.
