Rolling Release (RR)
The Rolling Release focuses on delivering the latest and newest features every three months. In addition to new features and other innovation updates, each Rolling Release also provides security patches and bug fixes. To benefit from the newest features, the highest security as well as from our technical support, you must download and install each upgrade.
If you prefer to get frequent upgrades to cutting-edge functionalities, then the Rolling Release is the lifecycle model to go with.
The Rolling Release has 3 months of Full Support followed by 4 months of Fade-Out Support. Customers have four months to change from one Rolling Release version to the next Rolling Release version. The new support period starts as soon as the newest version is delivered.
This means that you have to upgrade at least twice per year to stay supported.
Example: You install the RR version of May 2020. You skip the next version (August 2020). When the November 2020 version is released, you upgrade directly to that. You must perform this upgrade within one month.
The Full Support stage starts with the release of a new Rolling Release version. Each new version includes software enhancements and new functionalities as well as updates, to improve the stability and performance of the platform and to address security vulnerabilities. Additionally, customers are entitled to receive technical support.
At the end of the Full Support period, the next RR version will be released. We recommend upgrading to this new version as soon as it is released.
RR Full Support starts on the day of the availability of the release and ends on the day before the availability of the next Rolling Release (RR+1).
The Fade-Out stage of a Rolling Release version starts as soon as the following, newest Rolling Release version (RR+1) is available. An RR version in Fade-Out stage must not be used for new Nevis projects.
During the Fade-Out stage, you are still entitled to receive technical support. But Nevis will no longer provide security patches or bug fixes.
RR Fade-Out Support ends one month after the latest RR version (RR+1) has entered the Fade-Out Support stage. This results in one month of overlapping Fade-Out Support of two Rolling Releases.
At the end of the Fade-Out Support period, after altogether 7 months of RR support, the product lifecycle of a Rolling Release is over.
