Release Process
Right after update release 11.0.<n-1> was branched from mercurial repository jdk11u-dev to jdk11u, the release The release cycle for release 11.0.<n> starts . As the very first step, its initial stage in the jdk11u-dev repository will be repository as soon as the previous release enters its second stage and is confined to the jdk11u repository. The starting point is tagged with jdk11.0.<n>+0. Once the previous release has happened, jdk11u-dev begins a cycle of being tagged on a weekly basis - when new changesets have been pushed - and the latest tag is promoted from jdk11u-dev to jdk11u. The tags have the format of jdk11.0.<n>+<build>, where <n> is the placeholder for the update release and <build> is the monotonically increasing build number.
About 6 weeks before its release, or One of the first changes should be to bump the version, e.g. something similar to JDK-8219710. At about 6 weeks before its general availability (GA), an update release enters ramp down phase 2 (RDP2) and the current state of jdk11u-dev will be transported to jdk11uenters Rampdown. From that point onwards, the update release is stabilized by only accepting very select fixes in jdk11u. Eligible candidates are fixes that Oracle has brought to their correspondent JDK11 update release, fixes for , such as regressions, high priority issues or and test fixes. Builds from jdk11u will be tagged Tagging again takes place on a weekly basis , - when new changesets have been pushed. The tags will have the format of jdk11.0.<n>+<build>, where <n> is the placeholder for the update release and <build> is the monotonically increasing build number. Each tag that gets set in jdk11u will be changes have occurred - but this time, it occurs in the opposite direction, with jdk11u changes being integrated back to jdk11u-dev in a timely manner. At about 2 weeks before GA. At the end of the month prior to the release month, a complete freeze will be anounced announced for jdk11u, allowing the maintainers of the security changes (currently Red Hat) to integrate and test these into the repository and perform final testing of the collected fixes in a secure, internal environment. At the On release day, these the final batch of changes will be merged into pushed to jdk11u and the final tags jdk11tags jdk11.0.<n>+<build> and jdk11.0.<n>-ga will be set. To complete the process, jdk11u changes are integrated back into jdk11u-dev.
