Changes from v0.5 to v2.0
Key Changes are outlined here: [Line Item V2 Changes](🔗)
A Line Item is the workhorse of the Buzz system. It corresponds to a given buying activity, usually defined by a set of targeting criteria. Line Items belong to Campaigns, and the sum of all budgets cannot exceed the Campaign budget.
Each Line Item is associated to a single Campaign and may be associated with one or more Creatives through the Creative Line Item Association. Line Items must have Creatives assigned before they can be set to Active. Note, multiple Creatives can be assigned to a single Line Item, and a single Creative can be assigned to multiple Line Items.
