6) Service Level Agreement

For Kyligence products deployed in the production environment, Kyligence technical support will meet the following initial response Service Level Agreement depending on the type of Support Subscription:

The product lifecycle of a major version of a Kyligence product ends 24 months after its next major version’s general availability date. After a major version’s product lifecycle, its iteration is over. 6 months after the product lifecycle marks the end of the support lifecycle. Customers should upgrade to the next major version of the Kyligence product to get product upgrades and technical support service.

Kyligence product’s version number is A.B.C.D, in which A is the major version number, B is the major iteration version number, C is the minor version number, and D is the build number.

Major Version: A major version release changes the major version number and build number (A.b.c.D). A new major version indicates key architecture changes and significant new features.

Major Iteration Version: A major iteration version release changes the major iteration version number and build number (a.B.c.D). A new major iteration version indicates new features and enhancements.

Minor Version: A minor version release changes the minor version number and build number (a.b.C.D). A new minor version indicates the enhancement of existing features.

Maintenance Version: A maintenance version release only changes the build number (a.b.c.D). A new maintenance version indicates only bug fixes.
