We've done a little bit of advance planning and there are now three
milestones which developers will be using to schedule upcoming
Issues and merge requests have been assigned to the relevant milestone.
All dates are approximate.
We will also be announcing (here) when the next release would include
database migrations so that admins have more notice of scheduled
downtime. When a milestone includes database migrations, other changes
which also include a database migration will be moved to that
milestone so that admins can minimise total downtime.
The next release is expected to include the changes from the 2018.12 milestone.
The 2019.02 milestone already includes database migrations.
