Every CloudBees Jenkins solution is based on a custom build of the Jenkins core. These CloudBees core releases are based on the Jenkins community's Long-Term Support (LTS) releases. This page compiles the release notes of Jenkins Core versions included in the different products:
x.y.z where z < 10 means that a community-built Jenkins LTS core has been used.x.y.z-cb-w where z < 10 means that a CloudBees-built Jenkins LTS core has been used, which should contain the same content that the x.y.z community release.x.y.z where z > 10 represents CloudBees-built Jenkins LTS cores that include additional backports, such as security fixes released after community support for the that LTS line has ended.org.jenkins-ci.mainjenkins-warwarThe documentation is available here.
