Release Schedule

OpenDaylight releases twice per year. The six-month cadence is designed to synchronize OpenDaylight releases with OpenStack and OPNFV releases. Dates are adjusted to match current resources and requirements from the current OpenDaylight users. Dates are also adjusted when they conflict with holidays, overlap with other releases or are otherwise problematic. Dates are the release deadlines intended for managed projects. Self-managed projects that wants to integrate the distribution have one week to release once managed projects are ready.

Each milestone is usually evaluated at a TSC meeting, which dictates deadlines. Nominal deadline is midnight UTC on the particular date. As an example, a date of 2022-10-06 means that all deliverables are due no later than 2022-10-06T00:00:00Z. The corresponding TSC meeting happens either on 9am or 10pm Pacific time. The slack time between the deadline and the actual call can be used for justified last-minute work if the need arises (though in general WE SHOULD NEVER need it). If such last-minute work results in a SimRel candidate build not being available, the reasons for that need to be discussed at, and documented as part of, the corresponding TSC meeting.
