4.11.0 (Jan 9, 2024)
- Added impressionsListener method in the IntegrationConfig builder to set Sync or Async Listener execution.
- Fixed localhost to read files with yml ending.

4.10.2 (Dec 1, 2023)
- Added getTreatmentsByFlagSets without attributes.
- Fixed some issues for flag sets: Not logging a warning when using flag sets that don't contain cached feature flags.

4.10.1 (Nov 8, 2023)
- Fixed handler for response http headers.

4.10.0 (Nov 2, 2023)
- Added support for Flag Sets on the SDK, which enables grouping feature flags and interacting with the group rather than individually (more details in our documentation):
  - Added new variations of the get treatment methods to support evaluating flags in given flag set/s.
    - getTreatmentsByFlagSet and getTreatmentsByFlagSets
    - getTreatmentWithConfigByFlagSets and getTreatmentsWithConfigByFlagSets
  - Added a new optional Flag Sets Filter configuration option. This allows the SDK and Split services to only synchronize the flags in the specified flag sets, avoiding unused or unwanted flags from being synced on the SDK instance, bringing all the benefits from a reduced payload.
    - Note: Only applicable when the SDK is in charge of the rollout data synchronization. When not applicable, the SDK will log a warning on init.
  - Updated the following SDK manager methods to expose flag sets on flag views.
- Added `defaultTreatment` property to the `SplitView` object returned by the `split` and `splits` methods of the SDK manager.
