General release information
Umbraco CMS, known for its flexibility and user-friendliness, has a structured release cycle. This cycle ensures that users have regular access to new features, improvements and security updates.
Release cycles and cadences of Umbraco
To keep Umbraco CMS development 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.
Twice a year, Umbraco releases a major release. These releases contain significant updates, including 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.
A minor release comes out every six weeks. These releases contain new features and functionalities that are backwards compatible. They contain no breaking changes and focus on further refining and extending the capabilities of the CMS.
Patches are released when needed. They mainly focus on fixing regression issues (bugs in the latest minor) and, in some cases, security issues.
Short-Term Support (STS) and Long-Term Support (LTS) in Umbraco
Umbraco offers two support types 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 who want 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 and then 12 months of security-only support.
Current and future versions of Umbraco
End-of-Life (EOL) of older Umbraco versions
The End-of-Life (EOL) concept is a crucial aspect in 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 ending both the 'Support' and 'Security' phases.
- No further updates: After reaching the EOL date, these versions will no longer receive patches, security updates or new features.
- Security risks: Continued use of a version that has reached EOL may 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 Umbraco support available: This means that in case of unexpected challenges or problems, we can no longer rely on Umbraco support.
Umbraco releases: support and security phases
To ensure the security 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 enhancements.
- The 'Support' phase Every major release of Umbraco has a 9-month 'Support' phase, extended to 24 months for LTS versions. During this phase, Umbraco fixes bugs, regressions and security issues. New projects can be started 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 3 months, or 12 months for LTS versions. Here, Umbraco focuses exclusively on security issues. At the end of this phase, the version is End Of Life (EOL) and its use is discouraged.
- Patches Patches usually focus on the last minor of a major release. Critical security patches can also target earlier minors, depending on the situation. With Umbraco cloud, these are performed automatically. Minor updates are optionally enabled automatically on cloud.
