Products lifecycle policy
Centreon has been publishing new releases of the Centreon solution at regular intervals since version 18.10, enabling the community, businesses and developers to plan their roadmaps with the guarantee of upstream visibility on the latest open source capabilities.
Version numbers
Releases of Centreon are named according to the year and period of delivery: XX.04 for the spring release, and XX.10 for the fall release. For example, Centreon 21.04 was released in spring 2021. All modules and components of the Centreon software suite use the same version numbers.
Release frequency
Centreon delivers two releases per year. The first will occur in the spring and will be major (including new products or features as well as larger architecture changes), while the second will be in the fall and will be minor (including primarily enhancements and fixes to existing features). Between these two, Centreon will regularly deliver minor updates (versioned YY.MM.NN), including security/vulnerability fixes, bug fixes and enhancements to the software.
Maintenance and security updates
Until version 21.04
Version 21.04 and prior versions have been supported for 18 months. The lifecycle of a version is divided into three phases:
- First phase: Bugs of all severity levels (minor, major, critical, blocker) and security issues are fixed according to their priority.
- Second phase: Major, critical bugs and blockers, or security issues are fixed according to their priority.
- Third phase: Blockers or security issues are fixed according to their priority.
Prioritization is made by Centreon’s Product team.
The first phase of the lifecycle begins on the day of a version release.
The second phase of a version begins when the next major version is available. For example, the release of Centreon 21.04 triggers the second phase of Centreon 20.10.
The third phase of a version begins when the second next major version is available. For example, the release of Centreon 21.04 triggers the third phase of Centreon 20.04 and the second phase of Centreon 20.10.
From version 21.10
From version 21.10, versions are supported for 2 years. The lifecycle of a version is divided into 2 phases of 12 months each.
- First phase: Bugs of all severity levels (minor, major, critical, blocker) and security issues are fixed according to their priority.
- Second phase: Major, critical bugs and blockers, or security issues are fixed according to their priority.
Prioritization is made by Centreon’s Product team.
