May 30, 2019 There are just two updates in this release, both to fix API issues so there are no user visible changes.
- RF-126 (Re)Work-around Facebook Ads per Adset Limit
Facebook limits the number of ads in an Adset to 50. In this update we’ve improved the selection process for what ad gets removed to make room for the new ad when an Adset reaches that limit. Specifically, we consider only inactive ads and sort them by date last updated. The oldest of these inactive ads is removed if needed to make room for a new one.
- RF-80 Reimplement MTurk API
AWS rolled out a completely new API and associated SDKs. The old one ceases to work June 1, so this is a required update.
