# Feature roadmap

In the following list, each feature is associated with a corresponding
milestone. The convention for the priorities are:

* P0 feature will block the milestone; we will delay the milestone
  date until the feature is shipped.
* P1 feature can delay the milestone if the feature can be shipped
  with a reasonable delay.
* P2 feature will be dropped and rescheduled for later rather than
  delaying the milestone.

We will update this list when reaching each milestone. Some milestones
may also be refined if appropriate.
