FDv2 is now available through an Early Access Program for the JavaScript, React, Android, and React Native client-side SDKs.

Data Saving Mode introduces several key enhancements:

• Improved resilience: recover more gracefully during network disruption or when streaming is unavailable.
• Lower reconnect overhead: reuse the SDK's current state on reconnect and request only what changed, often reducing repeated data transfer by more than 90%.
• Better performance for larger-scale client-side use cases: especially helpful when payload size, reconnect behavior, or bandwidth usage matter.
• Automatic fallback behavior: supported implementations improve behavior when streaming is unavailable.
