Release Schedule
================
-OpenDaylight releases twice per year, on the Thursdays closest to March 7th and
-September 7th.
-
-The six-month aspect of the cadence is designed to synchronize OpenDaylight
-releases with OpenStack and OPNFV releases. The closest-Thursday aspect is
-designed to cause release events to occur on the same day as TSC meetings.
-Dates may be manually adjusted if they conflict with holidays or are otherwise
-problematic.
+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.
