The community produces feature releases every 6 months. Check the Community Lustre Roadmap to find out when the next one is scheduled. At the beginning of the development cycle, the features that will be included into the upcoming release are decided, and a landing schedule is worked out to ensure that not all of the features try to land in the week before the code freeze. The feature code freeze may be as early as 3 months prior to the release date, depending on the number and scope of features that are to be landed.

1. T-7 A call for features is sent out to the lustre-devel mailing list. The amount of change that can be landed for a given release is limited so it is prudent to respond early if you feel that you will have a feature that warrants consideration for inclusion. Expect to be asked to provide the information on the Feature Landing Checklist below - either completed or with estimates as to when any missing portions will be completed. Typically, feature development is already well underway before a feature is scheduled for landing.
2. T-6 Initial review of candidate features to define the scope of the release. A test plan is created and the Community Lustre Roadmap is updated. A landing schedule is created so that feature landings are spaced out to make it easier for intermediate testing to identify when features introduce regressions. If serious regressions are found when a feature is landed then it will be reverted from master until the problems have been addressed. It should be obvious that not all changes can land in the last weeks before the feature freeze, hence the requirement that features already be close to completion before scheduling them for landing.
3. T-3 Feature Freeze - feature landing is finished, bug fixes only from now on. The Community Lustre Roadmap is updated.
4. T-1 Code Freeze - critical bug fixes only from now on. A release candidate (RC) is tagged and release testing commences
5. T0 GA announced and RPMs available for download from the Intel Whamcloud download site
