Notable changes to 4.7 Release CycleReduce release cycle length to 6 months:

– 4 months development– 2 months freeze, with earlier creation of release branch based on risk assessment– Xen 4.7 will be slightly longer to support future June / December releases

Fixed and predictable Release dates– Beginning of June and December of each year– Eat into next cycle if we don't release on time

Fixed cut-off date: – Freeze dates: last day of March and September of each year– No more freeze exceptions, but heads-up mails about freeze will be sent a few weeks

beforehand
