Product 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.

From version 24.10

Version numbers

Releases of Centreon are named according to the year and period of delivery. For example, Centreon 22.10 was released in October 2022. All modules and components of the Centreon software suite use the same version numbers.

Release frequency

Starting with Centreon 24.10, Centreon will release one major version per year.

Minor versions, with bug fixes and minor improvements will be released on a monthly basis. A Service Pack version, cumulating all minor versions changes, will typically be delivered after six months.

Maintenance and security updates

• All Open Source major versions are supported for 18 months.
• Commercial major versions released in 2024, 2026 and any even years are LTS versions (supported for 3 years).
• Commercial major versions released in 2025, 2027 and any odd years are supported for 18 months.

Lifecycle

The lifecycle of a version is divided into three phases:

1. First phase: Bugs of all severity levels (minor, major, critical, blocker) and security issues are fixed according to their priority. Functional enhancements are added.
2. Second phase: Major, critical bugs and blockers, or security issues are fixed according to their priority.
3. Third phase: Blockers or security issues are fixed according to their priority.

The prioritization is determined 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 25.10 triggers the second phase of Centreon 24.10.

The third phase of a version begins when the second next major version is available. For example, the release of Centreon 26.10 triggers the third phase of Centreon 24.10 and the second phase of Centreon 25.10.

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 were supported for 18 months. The lifecycle of a version is divided into three phases:

1. First phase: Bugs of all severity levels (minor, major, critical, blocker) and security issues are fixed according to their priority.
2. Second phase: Major, critical bugs and blockers, or security issues are fixed according to their priority.
3. Third phase: Blockers or security issues are fixed according to their priority.

The prioritization is determined 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

Since version 21.10, versions are supported for two years. The lifecycle of a version is divided into two phases of 12 months each.

1. First phase: Bugs of all severity levels (minor, major, critical, blocker) and security issues are fixed according to their priority.
2. Second phase: Major, critical bugs and blockers, or security issues are fixed according to their priority.

The prioritization is determined by Centreon’s Product team.
