Release support and commitments

Learn about the WEKA software release cycle, support timelines, and upgrade policies to maintain system reliability and security.

WEKA provides a structured release cycle to deliver regular updates while ensuring long-term product support.

Release cycles

WEKA offers two types of release cycles:

• Innovation cycle: A new innovation cycle starts twice a year and includes monthly updates for six months. These releases deliver new features, enhancements, and security updates.

• Long-Term Support (LTS) cycle: WEKA designates an LTS release after every two innovation cycles. An LTS release is supported for two years, providing a stable and reliable platform. For example, version 4.4 is the LTS release that follows the 4.2 LTS release, as illustrated in the support phases diagram below.

Support phases

Each release cycle consists of distinct support phases. The length of each phase depends on whether the release is an Innovation or LTS version.

• Innovation: This phase lasts for six months for non-LTS releases. It includes new features and proactive updates.

• Proactive updates: This phase is the first year of an LTS release. It provides new features, OS and hardware compatibility enhancements, and security updates.

• Critical updates: This phase is the second year of an LTS release. It delivers essential security updates and minimal OS and hardware support.

Update and upgrade policy

To ensure you benefit from the latest improvements and security enhancements, adhere to the following policies:

• Innovation releases: You must apply updates within 90 days of their release to remain supported. For example, it is not permissible to use version 4.3.0 for a year without updating to the newer 4.3.x releases. WEKA addresses defects in subsequent releases rather than as hotfixes for older releases.

• Upgrade paths: You can transition from an innovation release cycle to an LTS release. WEKA guarantees upgrades from one major LTS version to the next.

• End of support: You must plan an upgrade to a supported version before your current version reaches the end of its critical update period. For assistance with planning and performing your upgrade, contact the Customer Success Team.

  WEKA does not support software versions that have reached their end-of-support date and disclaims liability for any issues that arise from using unsupported versions.
