[4.0.0-beta]

May 5th, 2023

New Features

The 4.0.0-beta release introduces a new primary feature, Advanced Audience Targeting
enabled through integration with Optimizely Data Platform (ODP) (#474,#481,#482,#483,#484,#485,#487,#489,#490,#494).

You can use ODP, a high-performance Customer Data Platform (CDP), to easily create complex
real-time segments (RTS) using first-party and 50+ third-party data sources out of the box. You can create custom schemas that support the user attributes important
for your business, and stitch together user behavior done on different devices to better understand and target your customers for personalized user experiences. ODP can
be used as a single source of truth for these segments in any Optimizely or 3rd party tool.

With ODP accounts integrated into Optimizely projects, you can build audiences using segments pre-defined in ODP. The SDK will fetch the segments for given users and
make decisions using the segments. For access to ODP audience targeting in your Feature Experimentation account, please contact your Optimizely Customer Success Manager.

This version includes the following changes:

  • New API added to OptimizelyUserContext:
    • fetchQualifiedSegments(): this API will retrieve user segments from the ODP server. The fetched segments will be used for audience evaluation. The fetched data will be stored in the local cache to avoid repeated network delays.
    • When an OptimizelyUserContext is created, the SDK will automatically send an identify request to the ODP server to facilitate observing user activities.
  • New APIs added to OptimizelyClient:
    • sendOdpEvent(): customers can build/send arbitrary ODP events that will bind user identifiers and data to user profiles in ODP.

For details, refer to our documentation pages:

Breaking Changes

  • OdpManager in the SDK is enabled by default, if initialized using OptimizelyFactory. Unless an ODP account is integrated into the Optimizely projects, most OdpManager functions will be ignored. If needed, OdpManager to be disabled initialize OptimizelyClient without passing OdpManager.
  • ProjectConfigManager interface has been changed to add 2 more methods getCachedConfig() and getSDKKey(). Custom ProjectConfigManager should implement these new methods. See PollingProjectConfigManager for reference. This change is required to support ODPManager updated on datafile download (#501).
