Today we're announcing the general availability of Structured Data Files (SDF) v4.2 in the DoubleClick Bid Manager API. Highlights of this release include:

• Support for TrueView connected TV bid adjustments
• Ability to inherit Insertion Order start and end dates at the Line Item level
• Renaming changes to better align SDF with the Display & Video 360 UI

All SDF users are encouraged to begin requesting v4.2 files to take advantage of these new features. To do so, simply pass 4.2 as the value of version when calling Sdf.download. For users with workflows that are dependent on older SDF formats, details of the file format changes between versions can be found in the release notes.
