We're happy to announce that 
v201905 of the Google Ad Manager API is available starting today. This version introduces a long-requested feature: 
Targeting Presets. The new 
TargetingPresetService allows you to read your network's targeting presets in a familiar 
Targeting object that can be applied to line items, forecasts, and proposal line items.
This release also introduces support for configuring and reporting on 
custom dimensions, and new 
Programmatic features such as 
Pause and 
Resume actions for Proposals.
For a full list of API changes in v201905, see the 
release notes.
For questions about these or any other API changes, reach out to us on the 
Ad Manager API forums.
