Umbraco Versions and their Support Timeframe

Umbraco is a popular content management system (CMS) that offers users exceptional flexibility, scalability and security features. Understanding Umbraco’s ecosystem, however, is a crucial task for users who wish to harness its full potential and effectively maintain their websites. Part of that is knowing which versions are still receiving support.

This article aims to provide clarity on Umbraco’s different release types and the support phases governing each version’s lifecycle.

We’ve created a timeline of current Umbraco versions and their corresponding support phases, which will allow users to make informed decisions about their platform and any next steps needed to ensure their systems remains up to date.

We’ll also discuss what to do next if your Umbraco version has reached – or will soon reach – End-of-Life status, ensuring you understand your options for maintaining a secure and functional website.

Umbraco Releases and Support Timeline

Umbraco Release Types

Umbraco is committed to maintaining its platform through regular, minor updates issued every six weeks. These minor releases focus on promptly delivering new features, functionality and improvements.

It’s important to note that these updates are never automatically pushed to live websites. This allows users to manage their own change process and roll out changes in their own time, ensuring it won’t break their website or application.

Significant changes that could potentially cause compatibility issues are reserved for new major releases. Currently, Umbraco releases major updates twice annually and these major releases are divided into two types: Standard Support and Long Term Support (LTS) releases.

Umbraco Standard-Term Support (STS)

Standard Support releases are regular Umbraco updates that introduce new features, enhancements and bug fixes. They keep the platform current with evolving technologies, address any potential security vulnerabilities and enhance user experience.

However, STS updates do not ensure backward compatibility with previous versions, requiring users to upgrade to access major new features and security patches.

Umbraco Long-Term Support (LTS)

Long Term Support (LTS) releases are designed for users prioritising stability and predictability over frequent feature updates. These versions provide an extended support period compared to standard releases, typically spanning several years.

Umbraco LTS versions focus on critical bug fixes, security patches and performance enhancements, while also ensuring backward compatibility and platform stability. This allows existing installations to upgrade smoothly without major disruptions, offering users a consistent platform for an extended duration.

Umbraco Support Phases

Umbraco follows a structured support framework comprising three phases: Support, Security, and End of Life (EOL). Understanding these phases - and knowing which stage your current Umbraco version is in – is essential to guarantee the stability, security and functionality of your website or application.

1. The “Support” Phase

During the Support Phase, the software version receives regular attention and updates from the Umbraco development team.

This phase involves addressing bugs, providing technical assistance, and releasing updates to enhance functionality and user experience. Users can expect active support forums, updated documentation, and assistance from both the community and official Umbraco support channels.

2. The “Security” Phase

Once an Umbraco version transitions to the Security Phase, it means it has reached the end of its standard support period.

In this phase, the focus shifts to solely addressing security vulnerabilities and providing critical security patches. Non-security-related bug fixes or feature enhancements are generally not provided during this phase.

Users are strongly advised to upgrade to a more supported version to continue receiving comprehensive assistance and access to new features.

3. End of Life (EOL)

The End of Life (EOL) Phase signifies that the version is no longer actively supported or maintained by the Umbraco team. During this final phase, Umbraco do not release any further updates, bug fixes or security patches.

Users still relying on EOL versions are at risk of security vulnerabilities and may encounter compatibility issues with newer technologies.

I-Finity highly recommend that anyone using an EOL version of Umbraco should upgrade or migrate to a supported version to ensure their websites remain secure and compatible with evolving web standards.
