 - Added `requestDropAgeHours` initial config property to set a time limit after which the requests would be removed if not sent to the server
 - Added a call to enroll users to A/B tests when getting a remote config value: 'getValueAndEnroll'
 - Added a call to enroll users to A/B tests when getting all remote config values: 'getAllValuesAndEnroll'
+- Added app version in all API requests.
 
 - Fixed sending '--' as carrier name due to platform changes from iOS version 16.4. This version and above will now not send any carrier information due to platform limitations.
 - Mitigated an issue where users could not enroll to an A/B tests if enrollment request has failed
