In the Trusty Tahr release schedule there are two phases called Feature Definition Freeze and Feature Freeze. It is pretty clear what the latter means but the wiki description of the first is not so clear. What happens with this phase?
The wiki description is:
By this date, all features with updates to be landed in main for the
release must be named and acknowledged by the Release Team. Having
this freeze gives them a chance to identify any features which should
be subject to an earlier Partner Update Deadline or Feature Freeze
deadline because they are especially risky. The list of features
should be sent to the Release Team mailing list.
It's a deadline to get all blueprints set into the appropriate
priority and approved for the next release.
Blueprints should have all Work Items properly defined in the "Work Items"
section.
Also, in order to show up properly on http://status.ubuntu.com/ubuntu-t/, blueprints
must be marked as approved, have an importance set and targeted to the
release.
