# Release cycle model

A new version of SonarQube Server is released every two months, with a new Long-Term Active (LTA) version (previously known as LTS) released every year. LTA is a functionally complete version of the product that will receive longer-term support.

This means that there are six releases of SonarQube Server per year, including the LTA version at the beginning of each year.

## Version scheme <a href="#version-scheme" id="version-scheme"></a>

SonarQube Server releases follow the following version scheme:

`YYYY.ReleaseNumber.PatchReleaseNumber`

The support policy is as follows:

* The latest version receives new features, enhancements, patches, and technical support.

<summary>How do I know if my SonarQube version is active?</summary>

1. In SonarQube Server, in the footer next to the version number, you can immediately see if your version is *active* or *no longer active.*

2\. Administrators can go to the **Administration** > **System.** As per above, you can see in the footer if you are on an active version.
