[META] Lightning 8.x-3.002

Will be released on 21 February. This will be the last release on the 8.4.x branch of Core and the last on 3.0.x branch of Lightning.

Scheduler

The Scheduler will not be ready for 3.0.2. It will likely be part of the 3.1.1 or 3.1.2 release.

• #2935715: Content authors should be able to set the date the content should be published
  This should be fairly straightforward. I think we only hid this on the creation form because we didn't have the UX worked out.
• #2936757: Schedule multiple transitions for a single node in serial
  This is more difficult. Consider using a separate, non-revisionable, non-translatable, non-fieldable entity and a multiple cardinality reference to that per revision/language.
